Summary of the Invention
[0005] Conventional designs all require an excessive increase in the number of parts. Focusing on the points mentioned above, the present invention aims to provide a cargo handling vehicle and a special cargo handling device equipped with a lighting component that has a simple structure and does not interfere with loading, unloading, or unloading of cargo. [Means for solving the problem]
[0006] A cargo handling vehicle having a vehicle section and a special equipment installed on the vehicle section, wherein the special equipment is capable of carrying a container, the special equipment has a cargo handling arm, and is capable of performing a loading operation in which the cargo handling arm is driven to pull the container onto the vehicle section and an unloading operation in which the container placed on the vehicle section is lowered to the ground by the cargo handling arm, and has a guide roller on which the container is placed, the guide roller is freely rotatable, and the container is in an inclined position with the guide roller as a fulcrum during at least one of the loading or unloading operations, the cargo handling vehicle has a lighting member, the lighting member is directly or indirectly attached to a member related to the guide roller.
[0007] Components related to the guide roller include the guide roller's support shaft, fixed shaft, brackets and stays that support the guide roller, etc. Components that rotate or oscillate along with the guide roller are also considered components related to the guide roller. The guide roller itself is also included in the components related to the guide roller. In this embodiment of the cargo handling vehicle, the container tilts with the guide roller as a pivot point. Since the guide roller supports the container, it is located below the container. In this embodiment of the cargo handling vehicle, the lighting member is directly or indirectly attached to a member related to the guide roller, so that the lighting member does not interfere with the container even when the container is tilted.
[0008] In the above-described embodiment, it is desirable that the lighting member is positioned so as to protrude outward in the width direction from the contact position of the guide roller with the container.
[0009] According to this embodiment, the lighting component is easily visible to following vehicles.
[0010] In each of the embodiments described above, it is preferable that the guide roller is mounted via a fixed shaft, the member associated with the guide roller is the fixed shaft, and the lighting member is mounted on the fixed shaft and positioned to protrude in the width direction from the guide roller.
[0011] According to this embodiment, fewer additional parts are needed.
[0012] In each of the embodiments described above, it is preferable that the loading arm has a dump arm, which is rotatably fixed and supports the container, swinging by power to tilt the container.
[0013] According to this embodiment, containers can be loaded and unloaded smoothly.
[0014] In each of the embodiments described above, the cargo handling arm preferably comprises a lift arm and a hook arm, wherein the lift arm is powered to swing, and the hook arm is equipped with an engaging portion for engaging with the container, is attached to the lift arm, and moves linearly.
[0015] This embodiment applies to a type of cargo handling vehicle known as a slide-type vehicle.
[0016] In each of the embodiments described above, it is preferable that the cargo handling arm comprises a lift arm and a hook arm, wherein the lift arm is powered to swing, and the hook arm is equipped with an engaging portion for engaging with the container, is attached to the lift arm, and swings relative to the lift arm.
[0017] This aspect is directed to a cargo handling vehicle called a swing type.
[0018] Another aspect for solving the same problem has a vehicle part and a special equipment device installed on the vehicle part. The special equipment device has an inclination means and a fulcrum member, and a part of the special equipment device or a load carried on the special equipment device can be inclined with the fulcrum member as a fulcrum by the inclination means. In the cargo handling vehicle, it has a lighting member, and the lighting member is characterized in that it is located at a position protruding in the vehicle width direction with respect to the fulcrum member.
[0019] In the cargo handling vehicle of this aspect, a part of the special equipment device or a load carried on the special equipment device is inclined with the fulcrum member as a fulcrum. That is, the object to be inclined (a part of the special equipment device or the load) is inclined with the fulcrum member as a fulcrum. Since the fulcrum member is located below the object to be inclined, even if the object to be inclined is in an inclined posture, it will not interfere with the lighting member. Also, in the cargo handling vehicle of this aspect, since the lighting member is located at a position protruding in the vehicle width direction with respect to the fulcrum member, the lighting member is easily visible from the following vehicle.
[0020] In each of the above aspects, it is desirable that the fulcrum member is attached via a fixed shaft, and the lighting member is attached to the fixed shaft and provided at a position protruding in the width direction of the fulcrum member.
[0021] According to this aspect, few additional parts are sufficient.
[0022] In each of the above aspects, it is desirable that the lighting member is swingable, and when a part of the special equipment device or a load carried on the special equipment device is inclined with the fulcrum member as a fulcrum, the lighting member is directly or indirectly urged by the object to be inclined and rotates.
[0023] For example, it is desirable that the lighting member is pushed directly or indirectly by the object to be inclined and rotates. According to this embodiment, the lighting member rotates in response to a change in the orientation of the inclined object. Therefore, it is less likely that waste discharged from the inclined object will come into contact with the lighting member.
[0024] In each of the embodiments described above, the special equipment is a device for mounting a container, and it is desirable that the container can be tilted using the pivot member as a pivot point.
[0025] This embodiment applies to container transport vehicles. According to this embodiment, even if the container is tilted when loading or unloading, it will not interfere with the lighting components.
[0026] In each of the embodiments described above, the special equipment is a vehicle carrier and has a lift frame and a slide body, and it is desirable that the lift frame is tilted with the pivot member as a pivot point.
[0027] This embodiment applies to vehicle carriers. According to this embodiment, even when the sliding body is in an inclined position when loading or unloading vehicles, it will not interfere with the lighting components.
[0028] In each of the embodiments described above, it is desirable that the special equipment includes a cargo bed or cargo box, and that the cargo bed or cargo box can be tilted with the pivot member as a pivot point.
[0029] This embodiment is intended for dump trucks and garbage collection vehicles. According to this embodiment, the lighting components will not interfere with the cargo bed or cargo box even when it is tilted.
[0030] Another embodiment for solving a similar problem is a cargo handling vehicle having a vehicle section and a special equipment installed on the vehicle section, wherein the special equipment has a tilting means and a pivot member, and the tilting means makes it possible to tilt a part of the special equipment or a load mounted on the special equipment with the pivot member as a pivot, and the cargo handling vehicle has a lighting member, wherein the lighting member is directly or indirectly attached to a member related to the pivot member.
[0031] Members related to a pivot member include members that support the pivot member, members that rotate or swing together with the pivot member, and members that rotate or swing around the pivot member as a central point. The pivot member itself is also included in the members related to the pivot member. For example, if a special equipment is used to load containers and has a loading arm, and drives the loading arm to perform a loading operation to pull the container onto the vehicle and an unloading operation to lower the container from the vehicle to the ground, then the loading arm can be said to be a component related to the pivot member. Furthermore, if the loading arm has a dump arm, then the dump arm can be said to be a component related to the pivot member. If the loading arm has a lift arm, then the lift arm can be said to be a component related to the pivot member. In this embodiment of the cargo handling vehicle, the lighting member is directly or indirectly attached to a member related to the pivot member, so that it does not interfere with the lighting member even when the container or the like is in an inclined position.
[0032] Another embodiment for solving a similar problem is a cargo handling vehicle having a vehicle section and a special equipment installed on the vehicle section, wherein the special equipment is for carrying a container, and the special equipment has a cargo handling arm, which is capable of performing a loading operation in which the cargo handling arm is driven to pull the container onto the vehicle section and an unloading operation in which the container placed on the vehicle section is lowered to the ground by the cargo handling arm, and has a lighting member, which is attached directly or indirectly to the cargo handling arm.
[0033] In this embodiment of the cargo handling vehicle, the lighting member is attached directly or indirectly to the cargo handling arm, so that it does not interfere with the lighting member even when the container or the like is in an inclined position.
[0034] Another embodiment for solving a similar problem is a special cargo handling device mounted on a vehicle that performs a predetermined function, the special cargo handling device having an inclination means and a pivot member, wherein the inclination means is capable of inclining a part of the special cargo handling device or a load mounted on the special cargo handling device with the pivot member as a pivot point, the special cargo handling device having a lighting member, the lighting member being positioned to protrude in the width direction of the vehicle relative to the pivot member.
[0035] The special cargo handling equipment of this embodiment is a device for converting a vehicle into a cargo handling vehicle, and is mounted on the vehicle to perform predetermined functions. According to this embodiment, even if the inclined object is tilted, it will not interfere with the lighting member. [Effects of the Invention]
[0036] The cargo handling vehicle and special cargo handling equipment of the present invention ensure that lighting components do not get in the way during loading, unloading, or unloading of cargo. [Brief explanation of the drawing]

[Modes for carrying out the invention]
[0038] Embodiments of the present invention will be described below. The invention as described in the claims is not limited to the embodiments described below. In the following explanation, the front and rear relationships are based on the front and rear of the cargo handling vehicle 1. That is, the front side means the side with the driver's seat 100, and the rear side means the opposite side. The lateral and width directions are both perpendicular to the front and rear directions of the cargo handling vehicle 1. The cargo handling vehicle 1 of this embodiment is a container transport vehicle of a type called a sliding type. The cargo handling vehicle 1 is a container transport vehicle called a detachable body vehicle and is equipped with a loading / unloading handling arm 3 for loading and unloading containers 2 between the vehicle and the ground. The loading / unloading handling arm 3 functions as a tilting means for tilting the container 2. Furthermore, as one of the cargo handling arms, there is a dump arm (dumping cargo handling arm) 16 for dumping the container 2. The dump arm 16 also functions as a tilting means for tilting the container 2.
[0039] First, let me briefly explain the overview of cargo handling vehicle 1. As shown in Figures 1 and 2, the cargo handling vehicle 1 has a vehicle section 5 and a special equipment 17. Vehicle section 5 is the body of a known truck, has an engine, and rotates its wheels to travel on the road.
[0040] The special equipment 17 is a device for loading and unloading containers 2 between the vehicle section 5 and the ground, and is mounted on the vehicle section 5. The special equipment 17 includes a container mounting section 11 on which the container 2 is placed, a dump arm (dumping load handling arm) 16, and a loading / unloading load handling arm 3. The container placement section 11 is the part on which the container 2 is placed, and has a frame (not shown) made of steel. The rear end of the dump arm 16 is attached to the frame 30 via a pin (not shown). The dump arm 16 swings relative to the frame 30, as shown in Figure 2.
[0041] The loading and unloading load handling arm 3 is composed of a hook arm 20 and a lift arm 21, as shown in Figure 2. The hook arm 20 has an overall shape that is roughly "L"-shaped, and a hook (engaging part) 23 is provided at its tip. The lift arm 21 has an overall straight shape. The cross-sectional shape of the lift arm 21 is frame-shaped. The base end of the hook arm 20 is inserted into the tip side of the lift arm 21. Therefore, the hook arm 20 can move linearly relative to the lift arm 21, and the overall length of the loading / unloading handling arm 3 itself can be extended or retracted. A slide cylinder (not shown) is attached to the hook arm 20, and by extending and retracting the slide cylinder, the hook arm 20 moves linearly relative to the lift arm 21. The lift arm 21 is pivotably attached to the middle section of the dump arm (dumping load handling arm) 16.
[0042] A lift cylinder 25 is attached to the lift arm 21. The lift arm 21 and the dump arm 16 have engaging parts (not shown), and by engaging these engaging parts, the lift arm 21 and the dump arm 16 can be swung together in the upright direction. Conversely, by disengaging the engaging parts, the lift arm 21 can be swung individually in the upright direction. In other words, when the lift cylinder 25 is extended with the engagement between the lift arm 21 and the dump arm 16 disengaged, as shown in Figure 1, only the lift arm 21 swings in the upright direction, and the container 2 can be lowered. When the lift cylinder 25 is extended with the lift arm 21 and the dump arm 16 engaged, as shown in Figure 2, the dump arm 16 swings in the upright direction and tilts, and the container 2 is dumped.
[0043] The container mounting section 11 is a frame on which the container 2 is mounted. Guide rollers 31a and 31b are provided at the rear end of the container mounting section 11. The guide rollers 31a and 31b are flanged rollers as shown in Figures 3 and 4. Specifically, the guide rollers 31a and 31b have a cylindrical roller body 32 that contacts the bottom of the container 2 and applies the load of the container 2, and a conical flange 33 is attached to the end of the roller body 32. The guide rollers 31a and 31b are supported on the fixed shaft 35 so as to be able to rotate freely. That is, the guide rollers 31a and 31b have bearings (not shown) inside, and the fixed shaft 35 is inserted through these bearings. The fixed shaft 35 is attached to the frame 30, and the guide rollers 31a and 31b are rotatably attached to the frame 30 via the fixed shaft 35.
[0044] As will be described later, when unloading or loading container 2, container 2 moves horizontally on the container mounting section 11. That is, container 2 maintains a horizontal position and moves linearly in the front-rear direction of the vehicle. At that time, the bottom of container 2 rests on guide rollers 31a and 31b, as shown in Figure 4. Since guide rollers 31a and 31b rotate freely, container 2 moves smoothly in a straight line. Furthermore, when unloading or loading container 2, the front of container 2 is lifted, causing container 2 to tilt. At this time, container 2 maintains contact with guide rollers 31a and 31b. As a result, container 2 swings around guide rollers 31a and 31b as pivot points. In other words, guide rollers 31a and 31b also function as pivot members, and container 2 (loaded material) (object to be tilted) mounted on the special equipment 17 tilts around guide rollers 31a and 31b as pivot points.
[0045] The cargo handling vehicle 1 of this embodiment has unique lighting members 40a and 40b. The lighting components 40a and 40b are composed of a group of lights 43 and a lighting support member 45. The lighting support member 45 is composed of a lighting support plate portion 47 and a connecting portion 48. The lighting group 43 consists of an upper light group 52 in which taillights 50 and brake lights 51 are arranged in a row, and a reverse light 55 provided below the upper light group. The light support plate portion 47 of the light support member 45 is a plate that supports the aforementioned light group 43. The light group 43 is attached to the lower region of the light support plate portion 47. The connecting portion 48 is a cylindrical part provided on the upper edge of the lamp support plate portion 47.
[0046] In this embodiment, the lighting members 40a and 40b are indirectly attached to the guide rollers 31a and 31b via a fixed shaft 35. The fixed shaft 35 is a component related to the guide rollers 31a and 31b, and in this embodiment, the lighting members 40a and 40b are directly attached to the fixed shaft 35, which is a component related to the guide rollers 31a and 31b. Furthermore, since the guide rollers 31a and 31b also function as pivot members, it can be said that the lighting members 40a and 40b are directly attached to the fixed shaft 35, which is a member related to the pivot member. In this embodiment, the total length of the fixed shaft 35 is longer than the total width of the two guide rollers 31a and 31b, and both ends of the fixed shaft 35 protrude laterally (in the width direction) from the two guide rollers 31a and 31b. The lighting members 40a and 40b are attached to the protruding portion. Specifically, a fixed shaft 35 is inserted through the cylindrical connecting portion 48 of the lighting members 40a and 40b. The lighting members 40a and 40b are suspended from both ends of the fixed shaft 35 and are swingable. The lighting members 40a and 40b are suspended from the portions of the fixed shaft 35 that protrude from the guide rollers 31a and 31b. The lighting members 40a and 40b are attached to the fixed shaft 35 and are positioned to protrude in the width direction from the guide rollers 31a and 31b.
[0047] In this embodiment, an automatic unloading operation can be performed by driving the loading / unloading arm 3 to lower the container 2. Furthermore, an automatic loading operation can be performed by driving the loading / unloading arm 3 to load the container 2. Additionally, a dumping operation can be performed by driving the dump arm (dumping arm) 16 to dump the container 2.
[0048] Next, we will explain the operation of the loading and unloading arms 3 of the special equipment 17 when unloading container 2, and the relationship between container 2, guide rollers 31a and 31b, and lighting members 40a and 40b. When the cargo handling vehicle 1 is loaded with container 2 and is traveling, each cargo handling arm is in the travel position shown in Figure 5(a). Specifically, the dump arm 16 is in a horizontal position and is resting on the container loading section 11. The lift arm 21 is also in a horizontal position, and container 2 is resting on the dump arm 16 and the container loading section 11. The position of container 2 is approximately horizontal. The hook arm 20 is located at the front end.
[0049] Then, the loading and unloading arms 3 of the special equipment 17 are driven to lower the container 2 to the ground. The lowering operation is carried out by sequentially executing the following steps. (1) Hook arm retraction process. (2) Lift arm swinging process.
[0050] (1) Hook arm retraction process The hook arm retraction process is a process in which the hook arm 20 is moved backward by a slide cylinder (not shown). By moving the hook arm 20 backward, the container 2 slides backward. That is, as shown in Figures 5(a) and (b), a portion of the container 2 rests on the guide rollers 31a and 31b, and since the guide rollers 31a and 31b rotate freely, the container 2 moves in a straight line while resting on the guide rollers 31a and 31b. As a result, the rear end of the container 2 protrudes rearward from the container mounting section 11, as shown in Figure 5(b).
[0051] (2) Lift arm swinging process The lift arm swinging process is a process that follows the hook arm retraction process, in which, with the hook arm 20 moved to its rear end, only the lift arm 21 is swung in the upright direction. As a result, container 2 slowly tilts. Specifically, as shown in Figure 5(c), the lift arm 21 is swung backward (clockwise in the diagram) to tilt the container 2.
[0052] As described above, container 2 protrudes rearward from the container mounting section 11, and even at this time, container 2 is in contact with the guide rollers 31a and 31b, and tilts with the guide rollers 31a and 31b (pivot members) as pivot points, as shown in Figure 5(c). When container 2 tilts, the rear end of container 2 moves downward. Although there are lighting components 40a and 40b below container 2, container 2 does not interfere with the lighting components 40a and 40b. In other words, in this embodiment, the lighting members 40a and 40b are attached to a fixed shaft 35 that supports the guide rollers 31a and 31b.
[0053] Focusing on the positional relationship in the front-to-back direction, the lighting members 40a and 40b are located approximately at the same position as the centerlines of the guide rollers 31a and 31b. Furthermore, focusing on the height direction, the lighting members 40a and 40b are located below the centerlines of the guide rollers 31a and 31b. In this embodiment, the bottom of the container 2 is supported by guide rollers 31a and 31b, and the container 2 is tilted with the guide rollers 31a and 31b (pivot members) as pivots. Therefore, the portion of the container 2 that is lower than the height of the guide rollers 31a and 31b is limited to the portion behind the portion that is in contact with the guide rollers 31a and 31b. In contrast, as mentioned above, the front-to-back positions of the lighting members 40a and 40b are the same as the centerlines of the guide rollers 31a and 31b, so the container 2 does not interfere with the lighting members 40a and 40b. Then, the lift arm 21 is swung further backward (clockwise in the diagram) to bring the rear end of the container 2 to the ground. The lift arm 21 is swung further backward (clockwise in the diagram) to bring the front end of the container 2 to the ground as shown in Figure 5(d), and the container 2 is lowered to the ground.
[0054] When loading container 2, the aforementioned operations are performed in reverse. Even when loading container 2, it tilts using the guide rollers 31a and 31b (pivot members) as pivots, so container 2 does not interfere with the lighting members 40a and 40b. Furthermore, as described above, the cargo handling vehicle 1 can dump the container 2. Even when dumping the container 2, the container 2 tilts using the guide rollers 31a and 31b as pivot points, so the container 2 does not interfere with the lighting members 40a and 40b.
[0055] The embodiment described above is a cargo handling vehicle 1 referred to as a slide type, but the present invention can also be applied to a cargo handling vehicle 200 referred to as a swing type, as shown in Figure 6. The loading and unloading load handling arm 3 of the swing-type cargo handling vehicle 200 is composed of a hook arm 20 and a lift arm 21. The loading and unloading load handling arm 3 has a hook arm 20 attached to the tip of the lift arm 21 so as to be able to swing at an angle, and its overall shape is roughly "L"-shaped. A hydraulic cylinder 22 is attached between the hook arm 20 and the lift arm 21, and the angle of the hook arm 20 relative to the lift arm 21 changes by extending and retracting the hydraulic cylinder 22.
[0056] A hook (engaging part) 23 is provided at the tip of the hook arm 20. The base end of the lift arm 21 is pivotably attached to the vehicle section 5, and the loading / unloading load handling arm 3 as a whole is pivotable. A lift cylinder 25 is also attached to the lift arm 21, and the loading / unloading load handling arm 3 as a whole is pivotable by the lift cylinder 25.
[0057] The operation of the swing-type cargo handling vehicle 200 is well known, so I will explain it briefly. When lowering container 2, the hook arm 20 is swung backward (clockwise in the diagram) as shown in Figure 7(b), and then the lift arm 21 is raised and changed to an inclined position as shown in Figure 7(c). In this embodiment as well, the bottom of the container 2 is supported by guide rollers 31a and 31b, and the container 2 is tilted with the guide rollers 31a and 31b (pivot members) as pivots. Therefore, the portion of the container 2 that is lower than the height of the guide rollers 31a and 31b is limited to the portion behind the portion that is in contact with the guide rollers 31a and 31b. In contrast, as mentioned above, the lighting members 40a and 40b are located at the same position as the centerlines of the guide rollers 31a and 31b, so the container 2 does not interfere with the lighting members 40a and 40b. As shown in Figure 7(d), container 2 is slowly lowered to the ground.
[0058] Furthermore, the cargo handling vehicle 200 can also dump container 2. Even when dumping container 2, since container 2 tilts using the guide rollers 31a and 31b as pivot points, container 2 does not interfere with the lighting members 40a and 40b.
[0059] The cargo handling vehicles 1 and 200 described above are all container transport vehicles, but the present invention can also be applied to other cargo handling vehicles. For example, the cargo handling vehicle 201 may be a vehicle transporter as shown in Figure 8. The cargo handling vehicle 201 has a vehicle section 5 and a special equipment 18. The special equipment 18 has a loading and unloading device 26. The loading and unloading device 26 is broadly composed of a lift frame 60, a tilt mechanism (inclination means) 57, and a slide body 28. The lift frame 60 is installed on the subframe 38 of the vehicle section 5. The subframe 38 is also provided with guide rollers 31a and 31b at its rear end, similar to the previous embodiment. The guide rollers 31a and 31b are supported by a fixed shaft 35 so as to be freely rotatable. Lighting members 40a and 40b are attached to the fixed shaft 35. The lift frame 60 rests on guide rollers 31a and 31b.
[0060] The slide body 28 is slidably mounted to the lift frame 60 and is suspended by a chain (not shown) or the like, which moves linearly along the lift frame 60. A footrest is also provided at the rear end of the slide body 28. Next, the unloading operation of the cargo handling vehicle 201 in this embodiment will be described.
[0061] When lowering the slide body 28 to the ground, the lift frame 60 is retracted as shown in Figure 9(b). The rear end of the lift frame 60 protrudes to the rear of the vehicle. When the lift frame 60 reaches the retracted position, the lift frame 60 tilts to a certain angle. As described above, the lift frame 60 is installed on the subframe 38 of the vehicle section 5 and swings around guide rollers 31a and 31b provided on the rear end side of the vehicle section 5.
[0062] When the lift frame 60 tilts, the lift frame 60 moves downward. Although there are lighting members 40a and 40b below the lift frame 60, the lift frame 60 does not interfere with the lighting members 40a and 40b. In other words, in this embodiment, the lighting members 40a and 40b are attached to the guide rollers 31a and 31b.
[0063] Therefore, focusing on the positional relationship in the front-to-back direction, the lighting members 40a and 40b are at the same position as the centerlines of the guide rollers 31a and 31b. Furthermore, focusing on the height direction, the lighting members 40a and 40b are below the centerlines of the guide rollers 31a and 31b. In this embodiment, the bottom of the lift frame 60 is supported by guide rollers 31a and 31b, and the lift frame 60 is tilted with the guide rollers 31a and 31b as pivot points. Therefore, the portion of the lift frame 60 that is lower than the height of the guide rollers 31a and 31b is limited to the portion behind the portion that is in contact with the guide rollers 31a and 31b. In contrast, as mentioned above, the lighting members 40a and 40b are located at the same position as the centerlines of the guide rollers 31a and 31b, so the lift frame 60 does not interfere with the lighting members 40a and 40b. Then the lift frame 60 is raised to its maximum angle, and the slide body 28 is lowered to the ground.
[0064] The loading and unloading vehicle may be a dump truck as shown in Figure 10, or a garbage collection vehicle as shown in Figure 11. The cargo handling vehicle 202 shown in Figure 9 is a dump truck and has a vehicle section 5 and a special equipment 207. The cargo handling vehicle 202 can tilt its cargo bed 205 using a cylinder (tilting means) 212. The cargo bed 205 swings around a pin (pivot member) 80. Lighting members 40a and 40b are also suspended from the pin 80 so as to be swingable. In this embodiment, a pressing piece 81 is provided on a part of the loading platform 205. The pressing piece 81 is a member whose orientation changes in accordance with the inclination of the loading platform 205. The pressing piece 81 is positioned close to the lighting members 40a and 40b, and when the loading platform 205 tilts, the pressing piece 81 pushes against the lighting members 40a and 40b. As a result, the lighting members 40a and 40b rotate around the pin 80, and their lower ends move forward. In other words, the lighting members 40a and 40b are indirectly biased to rotate by the tilting object (loading platform 205) via the pressing piece 81, and their lower ends move forward. Therefore, when soil and other materials are discharged from the cargo bed 205, it is less likely that the soil and other materials will come into contact with the lighting components 40a and 40b.
[0065] The cargo handling vehicle 210 shown in Figure 11 is a refuse collection vehicle and has a vehicle section 5 and a special equipment 220. The cargo handling vehicle 210 has a cylinder (tilting means) 212 that can tilt the cargo box 211. Similar to the cargo handling vehicle 201 shown in Figure 10, the cargo box 211 swings around the centerline of a pin (pivot member) 80. Lighting members 40a and 40b are also suspended from the pin 80 so as to be swingable. A pressing piece 81 is provided on a part of the cargo box 211, and when the cargo box 211 is tilted, the pressing piece 81 pushes the lighting members 40a and 40b, causing their lower ends to move forward. In other words, the lighting members 40a and 40b are pivotable, and when a part of the special equipment (cargo box 211) is tilted with the pivot member (pin 80) as the pivot point, the lighting members 40a and 40b are indirectly pushed via the pressing piece 81 attached to the tilting object (cargo box 211), causing them to rotate and the lower ends of the lighting members 40a and 40b to move forward. Therefore, when debris is discharged from the cargo box 211, it is less likely that the debris will come into contact with the lighting components 40a and 40b. In the embodiment described above, the lighting members 40a and 40b were indirectly pressed (biased) via the pressing piece 81, but the lighting members 40a and 40b may also be directly pressed and rotated by an inclined object such as a loading platform 205, a loading box 211, or a container 2. Alternatively, the pin (pivot member) 80 may be fixed to the cargo bed 205 side, and the pin 80 may be rotated in accordance with the inclination of the object to be inclined, and the lighting members 40a and 40b may be biased and rotated by the rotation of the pin 80.
[0066] In the embodiments described above, the lighting members 40a and 40b are attached to the guide rollers 31a and 31b (pivot members). In other words, in the embodiment described above, a fixed shaft 35 is used as a member related to the guide rollers 31a and 31b and the pivot member.
[0067] Other components related to the guide rollers 31a and 31b and the pivot members include a cargo handling arm. Figure 12(a) shows an example in which a loading / unloading cargo handling arm 3 is used as a component related to the pivot members. In the cargo handling vehicle of the embodiment shown in Figure 12(a), the lighting members 40a and 40b are attached to the dump arm (dumping cargo handling arm) 16 of the loading / unloading cargo handling arm 3. Specifically, the cargo handling vehicle shown in Figure 12(a) is equipped with a loading / unloading load handling arm 3. The loading / unloading load handling arm 3 has a dump arm 16. The dump arm 16 is a member that rotates and swings around a pivot member and is a member related to the pivot member.
[0068] Figure 12(b) shows an example in which a container mounting section 11 is used as a component related to the pivot member. In the cargo handling vehicle of the embodiment shown in Figure 12(b), the lighting members 40a and 40b are attached to the container mounting section 11. In the cargo handling vehicle shown in Figure 12(b), pivot members are attached to the components that make up the container loading section 11. In the cargo handling vehicle shown in Figure 12(b), the container mounting section 11 is a component that rotates and swings around the pivot member; therefore, the container mounting section 11 is a component related to the pivot member.
[0069] In the embodiments described above, a fixed shaft was inserted through the guide roller and the lighting member was attached via the fixed shaft. However, the lighting member may also be attached directly to the guide roller or pivot member. For example, a long roller may be used as the guide roller, and lighting members may be attached to both ends thereof. The functions and number of lamps belonging to the lighting component are not limited, and may include lamps with other functions, or may not include the lamps described in the above-described embodiment. The support structure for the lighting components is also optional.
[0070] The inventions according to the embodiments described above can be substituted or combined as long as no contradictions arise. Furthermore, the above embodiments allow for the free substitution or addition of components between each embodiment, as long as they fall within the technical scope of the present invention.
