Description

Technical Field

[0001] This invention relates to the field of frozen food conveying technology, and is particularly applicable to a frozen food transport device. Background Technology

[0002] Frozen products in blocks are usually transported to designated areas for cutting and packaging by a combination of manual handling and conveyor line transportation. After a batch of frozen products is frozen, they are first moved to the conveyor line by manual handling, and then transported to different designated areas by the conveyor line. This transportation method is inefficient and time-consuming.

[0003] To meet the conveying requirements, multiple conveyor lines need to be laid out on the ground, which occupies ground space and increases the initial equipment investment cost. To meet the requirements of continuous production, manual handling is required and the conveyor lines need to run continuously, which increases the energy consumption of the conveyor lines and the failure rate.

[0004] In response to the above situation, in order to better reduce costs, reduce labor intensity, utilize space, and improve the performance of the equipment, there is an urgent need for a transportation device that can achieve multi-area transportation without occupying ground space and without requiring manual handling. Summary of the Invention

Therefore, they should not be construed as limiting the scope of protection of this invention. The embodiments of this invention will now be described in detail with reference to the accompanying drawings.

[0029] It should be understood that the accompanying drawings are for illustrative purposes only.

[0030] A frozen food transport device, such as Figures 1-20 As shown, it includes a large trolley module 1, a small trolley module 2 mounted on the large trolley module 1, a lifting module 3 connected to the small trolley module 2, a clamping module 4 mounted on the lifting module 3, a stabilizing module 5 to prevent the frozen product 8 from shaking, and a control system 6 to realize the automated operation of the device.

[0031] like Figures 1-4 As shown, the trolley module 1 includes a trolley main beam 12, a trolley end beam 13, a trolley moving assembly, a trolley drive assembly 14, and a transmission assembly. A rail 11 is installed at the top of the operating site. The trolley main beam 12 is connected to the trolley end beam 13, which is mounted on the rail 11. The trolley drive assembly 14 drives the transmission assembly and simultaneously drives the trolley moving assembly to move the trolley end beam 13 along the rail 11.

[0032] Specifically, at least two main beams 12 are provided, and they are arranged in parallel. There is space between two adjacent main beams 12 to facilitate the installation of the trolley module 2. At least two end beams 13 are also provided. The end beams 13 are located at both ends of the main beams 12 and are used to connect the main beams 12, forming a stable trolley frame with the main beams 12 and the end beams 13.

[0033] The trolley moving assembly is configured as trolley traveling rollers 15. The trolley end beam 13 adopts a box-shaped structure. The trolley traveling rollers 15 are installed inside the trolley end beam 13 and extend out of the trolley end beam 13 to contact the rail steel 11. The trolley drive assembly 14 includes a trolley drive motor 141 and a trolley reducer 142. The trolley drive motor 141 is mounted on the trolley end beam 13, and the trolley reducer 142 is connected to the trolley drive motor 141. The trolley reducer 142 is installed outside the trolley end beam 13. To enable the transmission of power from outside the trolley end beam 13 to the trolley traveling rollers 15 inside the trolley end beam 13, and to avoid the trolley reducer 142 directly bearing the radial load and impact load of the trolley traveling rollers 15, while ensuring reliable transmission and convenient maintenance, a transmission assembly is set up for transmission.

[0034] The transmission assembly is configured as a gear pair, which smoothly transmits the output torque of the trolley reducer 142 to the roller shaft of the trolley traveling roller 15, allowing the trolley traveling roller 15 to travel smoothly along the rail steel 11 without affecting its load-bearing function. Alternatively, the transmission assembly can be configured with sprocket and chain drive, synchronous belt drive, friction wheel drive, worm gear drive, etc., to achieve rotational movement of the traveling roller on the rail steel 11.

[0035] like Figure 2 , Figures 5-7 As shown, the trolley module 2 includes a trolley main beam 21, a trolley end beam 22, a trolley moving assembly, and a trolley driving assembly 23.

[0036] Specifically, at least two main beams 21 are provided for the trolley, and they are arranged in parallel; at least two end beams 22 are also provided, and the end beams 22 are located at both ends of the main beams 21 to connect the main beams 21 and form a stable trolley frame. The end beams 22 are located on the main beam 12 and can drive the trolley frame to move on the main beam 12. Specifically, rail steel 11 is laid on the main beam 12, and the end beams 22 are located on the rail steel 11.

[0037] The trolley moving assembly includes trolley traveling rollers 24, which are disposed inside the trolley end beam 22 and extend out of the trolley end beam 22 and contact the rail steel 11.

[0038] The trolley drive assembly 23 includes a trolley drive motor 231, a trolley reducer 232, a connecting shaft 233, and a sprocket assembly. The trolley drive motor 231 is mounted on the main trolley end beam 13. The trolley reducer 232 is connected to the trolley drive motor 231. When the trolley drive motor 231 rotates, the trolley reducer 232 rotates synchronously. To ensure that the two trolley end beams 22 can move synchronously and stably on the two main trolley beams 12, the trolley reducer 232 is configured as a dual-output reducer, and sprocket assemblies are provided at both ends of the dual-output reducer.

[0039] The connecting shaft 233 is mounted on another large trolley end beam 13. Sprocket assemblies are mounted at both ends of the connecting shaft 233. Because the span of the connecting shaft 233 is large, a support bearing is mounted on the large trolley end beam 13. The connecting shaft 233 is connected to the support bearing to prevent the connecting shaft from deforming or shaking.

[0040] The sprocket assembly includes a traction chain 234, sprockets 235, and a chain fixing seat 236. Four sprockets 235 are provided, and each sprocket 235 is connected to the two output shafts of the dual-output reducer and the two ends of the connecting shaft 233. The same traction chain 234 is provided on two sprockets 235 near the same main beam 12 of the trolley. Two traction chains 234 are provided on the four sprockets 235. The chain fixing seat 236 is provided on the trolley end beam 22. After the traction chain 234 passes over two sprockets 235, its two ends are respectively connected to the chain fixing seat 236. The trolley drive motor 231 drives the trolley reducer 232 to rotate, which in turn drives the sprockets 235 at both ends of the reducer 232 to rotate, thereby pulling the traction chain 234 to rotate. Since both ends of the traction chain 234 are fixed to the trolley end beam 22, the trolley module 2 moves along the length of the main beam 12 of the trolley through the traction of the two sets of traction chains 234. The direction of movement of the trolley module 2 can be changed by changing the forward and reverse rotation of the trolley drive motor 231.

[0041] To prevent the traction chain 234 from rubbing against the trolley main beam 21 when it moves, a chain bracket is provided on the trolley main beam 21, and the traction chain 234 is mounted on the chain bracket.

[0042] like Figure 8 As shown, the lifting module 3 includes an electric hoist 31, which is mounted on the main beam 21 of the trolley. The electric hoist 31 is connected to the clamping module 4 through a flexible traction component, which drives the clamping module 4 to lift and lower, thereby driving the frozen product 8 to lift and lower.

[0043] Furthermore, the flexible traction component consists of two steel wire ropes 32 extending from the electric hoist 31. One end of each steel wire rope 32 is connected to the electric hoist 31, and the other end is fixedly connected. Specifically, a first pulley assembly 33 is provided on the trolley main beam 21, and a second pulley assembly 34 is provided on the clamping module 4. One steel wire rope 32 passes vertically downward through the second pulley assembly 34 in the clamping module 4 and returns, then is fixed. The other steel wire rope 32 passes through the first pulley assembly 33 between the trolley main beams 21, then passes vertically downward through the other second pulley assembly 34 in the clamping module 4 and returns, then is fixed. When the electric hoist 31 operates, it drives the clamping module 4 to move vertically and synchronously.

[0044] Furthermore, two sets of the first pulley assembly 33 are provided, one at the middle of the trolley main beam 21 and the other at the end away from the electric hoist 31. Each first pulley assembly 33 includes a pulley seat and a pulley. The pulley seat is fixed to the trolley main beam 21, and the pulley is mounted on the pulley seat and can rotate on the pulley seat. Another strand of the wire rope 32 passes through the bottom of the first pulley to prevent wear and reduce effort, then passes through the second pulley, causing the wire rope 32 to change direction and extend towards the clamping module 4. It then passes through another second pulley assembly 34 of the clamping module 4 and returns. When the electric hoist 31 retracts the rope, the two wire ropes 32 are pulled upwards simultaneously, causing the clamping module 4 to rise vertically; when the electric hoist 31 releases the rope, the two wire ropes 32 are released simultaneously, and the clamping module 4 descends vertically simultaneously. The wire ropes 32 on both sides are subjected to balanced force and have consistent stroke, ensuring that the clamping module 4 remains horizontal, without tilting or twisting during the lifting and lowering process.

[0045] Specifically, because the clamping module 4 has a large weight after clamping the frozen product 8, in order to prevent the fixed end from falling off, wedges 35 are set at the movable ends of the two steel wire ropes 32, and wedge sleeves 36 are set on the main beam 21 of the trolley, with the wedges 35 placed inside the wedge sleeves 36.

[0046] The vertical lifting drive mechanism of the clamping module 4 is not limited to the electric hoist 31. It can also be an electric roller double drum mechanism, a servo motor double drum mechanism, a hydraulic cylinder lifting mechanism, a ball screw lifting mechanism, or a lifting chain lifting mechanism, all of which can achieve stable vertical lifting of the clamping components of the frozen products 8.

[0047] like Figures 9-12As shown, the clamping module 4 includes a connecting main beam 41, a clamping power assembly, and a clamping assembly. The second pulley assembly 34 has the same structure as the first pulley assembly 33, and two sets of the second pulley assembly 34 are respectively located on both sides of the connecting main beam 41. The clamping power assembly is mounted on the connecting main beam 41, and the clamping assembly is connected to the clamping power assembly. The clamping power assembly drives the clamping assembly to clamp or release the frozen product 8.

[0048] Specifically, the clamping power assembly includes an air compressor 421, an air tank 422, a self-control valve 423, and a clamping cylinder 43. The air compressor 421, air tank 422, and self-control valve 423 are all mounted on the connecting main beam 41. A cylinder mounting seat is mounted on the connecting main beam 41. The clamping cylinder 43 is connected to the cylinder mounting seat via a pin. Multiple clamping cylinders 43 are evenly arranged along the length of the connecting main beam 41. The control system 6 sends a clamping or releasing signal, the air compressor 421 delivers compressed gas to the air tank 422, and the compressed air in the air tank 422 is delivered to or depressurized by the automatic valve to the clamping cylinder 43, causing the clamping cylinder 43 to extend or retract.

[0049] Of course, the clamping power assembly can also be driven by an electric push rod, a servo motor with a lead screw and nut mechanism, or a hydraulic cylinder.

[0050] The clamping assembly includes clamping rods 441, each corresponding to a clamping cylinder 43. Further, a clamping ear plate is provided in the middle of the clamping rod 441. The clamping cylinder 43 is rotatably connected to the clamping ear plate. One end of the clamping rod 441 is rotatably connected to the connecting main beam 41. The clamping cylinder 43 drives one end of the clamping rod 441 to rotate around its connection point with the connecting main beam 41, while the other end moves towards or away from the frozen product 8 to clamp or release the frozen product 8. Specifically, the clamping cylinder 43 is connected to the clamping ear plate via a pin; clamping mounting seats are provided on both sides of the connecting main beam 41, and the end of the clamping plate is loosely connected to the clamping mounting seat, allowing free rotation.

[0051] To ensure reliable clamping of the frozen product 8, spike teeth 442 are provided on the side of the clamping rod 441 near the frozen product 8. The spike teeth 442 extend out of the clamping rod 441 and can be evenly distributed along the clamping rod 441. The clamping cylinder 43 drives the clamping rod 441 to move towards the frozen product 8, and the spike teeth 442 embed into the frozen product 8, firmly locking it in place to prevent it from falling. When the frozen product 8 reaches the designated position, the clamping cylinder 43 retracts, the connecting rod moves away from the frozen product 8, and the spike teeth 442 pull out the frozen product 8, placing it in the designated position. Specifically, the tips of the spike teeth face the top of the clamping rod. After the spike teeth are inserted into the frozen product, the upward-facing tips effectively prevent the frozen product from sliding down due to gravity, improving the firmness and stability of the clamping and preventing the frozen product from falling off during transport or clamping.

[0052] To further prevent the frozen product 8 from falling during transport, a protective assembly is installed on the connecting main beam 41. This assembly includes a protective cylinder 451, a protective connecting rod 452 connected to the protective cylinder 451, and a protective support plate 453 connected to the protective connecting rod 452. The protective cylinder 451 is located at both ends of the connecting main beam 41, and protective mounting seats are provided at both ends of the connecting main beam 41. One end of the protective cylinder 451 is mounted on the protective mounting seat, and its output end is connected to the protective connecting rod 452. Protective ear plates are provided on the protective connecting rod 452, and the protective cylinder 451 is rotatably connected to the protective ear plates. One end of the protective connecting rod 452 is rotatably connected to the connecting main beam 41, and the other end is connected to the protective support plate 453. When the lifting module 3 lifts the frozen product 8, the protective cylinder 451 drives the protective connecting rod 452 to move. One end of the protective connecting rod 452 rotates around the connection point with the connecting main beam 41, and the other end drives the protective support plate 453 to rotate towards or away from the bottom of the frozen product 8.

[0053] The protective tray 453 can cover all frozen products 8, or a set of protective components can be set under each frozen product 8. In this solution, the protective tray 453 covers all frozen products 8.

[0054] To maximize the number of clamps, the clamping components are provided on both sides of the connecting main beam 41. Therefore, protective components are also provided on both sides of the connecting main beam 41. When the protective cylinder drives the protective connecting rod to rotate, the protective tray 453 closes or opens below the frozen product 8.

[0055] like Figure 13As shown, to facilitate the transport of frozen goods 8 in any direction, a rotating assembly 7 is installed on the connecting main beam 41. The rotating assembly 7 includes a rotating beam 71 and a rotating drive assembly 72. At this time, the second pulley assembly 34 is installed on the rotating beam 71, and the lifting module 3 is connected to the rotating beam 71 via a steel wire rope 32. The rotating drive assembly 72 includes a rotating drive motor, a rotating reducer 721 connected to the rotating drive motor, a drive gear 722 connected to the rotating reducer 721, and a driven gear 723 meshing with the drive gear 722. The rotating drive motor and the rotating reducer 721 are both installed on the rotating beam 71. The driven gear 723 is connected to the connecting main beam 41. The drive gear 722 drives the driven gear 723 to rotate, thereby driving the clamping module 4 to rotate.

[0056] To ensure the connection between the clamping module 4 and the rotating assembly 7, a connector is provided on the connecting beam to connect the connecting beam and the driven gear 723. Specifically, the connector includes a rotating shaft 725 connected to the driven gear 723 and a rotating bearing 724 mounted on the rotating beam 71. The connection between the rotating shaft 725 and the rotating bearing 724 ensures the connection between the clamping module 4 and the rotating assembly 7 without affecting the rotation of the clamping module 4. Furthermore, a connecting housing is provided on the connecting beam, and the rotating bearing 724 is disposed within the connecting housing. The rotating shaft 725 is inserted into the middle of the rotating bearing 724, and a connecting nut is provided at the end of the rotating shaft 725 away from the driven gear 723. The connecting drive motor drives the connecting reducer to rotate, synchronously driving the driving gear 722 to rotate the driven gear 723, thereby rotating the clamping module 4 to meet multi-angle placement requirements.

[0057] like Figure 1 , Figure 13 As shown, since the clamping module 4 is pulled by the wire rope 32, when the trolley module 2 moves left and right or the trolley module 1 moves forward and backward, swaying in different directions will occur due to inertia. To ensure the stability of the device and avoid swaying, a stabilizing module 5 is provided on the clamping module 4. One end of the stabilizing module 5 is connected to the trolley module 2, and the other end is connected to the clamping module 4. The stabilizing module 5 has a degree of freedom of extension and retraction in the vertical direction and provides a rigid constraint against swaying in the horizontal direction for the clamping module 4. When the clamping module 4 is raised or lowered, the stabilizing module 5 generates corresponding extension and retraction deformation. In this solution, the stabilizing module 5 can be set as a crank assembly or a telescopic sleeve.

[0058] Specifically, the crank assembly includes a first connecting arm 51 and a second connecting arm 52. One end of the first connecting arm 51 is connected to the main beam 21 of the trolley, and the other end is connected to the second connecting arm 52. The other end of the second connecting arm 52 is connected to the clamping module 4. The first connecting arm 51 and the second connecting arm 52 are rotatably connected. During the lifting and lowering process of the clamping module 4, the ends of the first connecting arm 51 and the second connecting arm 52 that are far apart from each other gradually move closer or further apart.

[0059] Crank seats 53 are respectively provided at the ends of the first connecting arm 51 and the second connecting arm 52 that are far apart from each other. The crank seats 53 are connected to the main beam 21 of the trolley or the clamping module 4. The crank seats 53 are rotatably connected to the first connecting arm 51 and the second connecting arm 52.

[0060] A first connecting member is provided at the end of the first connecting arm 51 near the end of the second connecting arm 52, and a second connecting member 521 is provided at the end of the second connecting arm 52 near the first connecting member. Specifically, the first connecting member includes a connecting plate connected to the first connecting arm 51, a sealing housing disposed on the connecting plate, and a crank bearing 54 disposed within the sealing housing. A rotating shaft 55 is inserted into the crank bearing 54, and the rotating shaft 55 can rotate within the crank bearing 54. The rotating shaft 55 is connected to the second connecting member 521. Specifically, the rotating shaft 55 extends out after passing through the second connecting arm 52 and the first connecting arm 51, and both ends of the rotating shaft 55 are connected to the first connecting member to prevent the rotating shaft 55 from falling off. The second connecting member 521 has a ferrule structure, which facilitates its installation on the rotating shaft 55. The rotating shaft 55 is connected to the second connecting member 521. When the first connecting arm 51 and the second connecting arm 52 rotate, the crank bearing 54 rotates around the rotating shaft 55.

[0061] To ensure the connection between the rotating shaft 55 and the crank bearing 54, a locking nut is provided at the end of the rotating shaft 55 to prevent the first connecting arm 51 and the second connecting arm 52 from falling off.

[0062] To prevent dust from entering the sealing housing, a dustproof ring is provided at the opening of the sealing housing. To prevent wear between the bearing and the sealing housing, a gasket is provided between the bearing and the sealing housing.

[0063] The sealing housing includes an upper end cover disposed on the first connecting plate and a sealing cover connected to the upper end cover. The upper end cover and the sealing cover are detachably connected, which facilitates the configuration of the internal structure of the sealing housing.

[0064] At least one set of crank assemblies is provided along the length direction of the trolley module 2 and at least one set along the width direction of the trolley module 2 to ensure stability. Preferably, three sets of crank assemblies are provided, and the angle between any two adjacent crank assemblies is configured to be 120° when viewed from above the transport device.

[0065] In some embodiments, such as Figures 16-20 As shown, the stabilizing module can also be configured as a telescopic sleeve. The telescopic sleeve includes a fixed housing 56, a primary telescopic sleeve 57 disposed in the fixed housing 56, and a secondary telescopic rod 58 disposed in the primary telescopic sleeve 57. The fixed housing 56 is connected to the clamping module 4, and the end of the secondary telescopic rod 58 extending out of the primary telescopic sleeve 57 is connected to the trolley main beam 21.

[0066] A locking element 59 is provided at the end of the secondary telescopic rod 58 that is housed within the primary telescopic sleeve 57. A locking element 59 is also provided at the end of the primary telescopic sleeve 57 that is housed within the fixed housing 56. The locking element 59 includes a spring 591 and a locking block 592 provided at the end of the spring 591. The locking block 592 can be provided at both ends of the spring 591 or only at one end. To ensure stability, the locking block 592 is provided at both ends of the spring 591. A first guide slope 593 is provided on the lower end surface of the locking block 592. The first guide slope 593 is provided from the outer end surface of the locking block 592 to the inner end surface and is inclined along the contraction direction. The inclination angle of the first guide slope 593 is set to 30°~60°. In this scheme, the inclination angle of the first guide slope 593 is set to 45°.

[0067] A first positioning slot 561 is provided at one end of the fixed housing 56, and a second positioning slot 571 is provided at one end of the primary telescopic sleeve 57. A second guide slope 594 is provided on both the first and second positioning slots. The first guide slope 593 and the second guide slope 594 are configured to cooperate with each other. The inclination angle of the second guide slope 594 is set to 30°~60°. After the secondary telescopic rod 58 extends to its limit, the spring 591 is released, and the locking block 592 extends and is locked in the second positioning slot 571. After the primary telescopic sleeve 57 extends to its limit, the spring 591 is released, and the locking block 592 extends and is locked in the first positioning slot 561 to prevent the telescopic rod from coming out. At the same time, it restricts the axial movement between the secondary telescopic rod 58 and the primary telescopic sleeve 57, as well as the axial movement between the primary telescopic sleeve 57 and the fixed housing 56. When the telescopic sleeve needs to be retracted, press down on the secondary telescopic rod 58. The locking part moves down synchronously, and the first guide slope abuts against the second guide slope. The axial thrust generates a radial inward force through the first guide slope, squeezing the spring and pushing the locking block out of the slot, thus releasing the axial limit.

[0068] At least two sets of telescopic sleeves are provided, and the two sets of telescopic sleeves are arranged along the length direction of the trolley module 2.

[0069] The control system 6 is electrically connected to the large vehicle module 1, the small vehicle module 2, the lifting module 3, and the clamping module 4 respectively to control the operation of each module and achieve automated control.

[0070] The specific operation process of the frozen food transport device 8 is as follows: A signal is sent to the control system 6 to start the trolley drive motor 141. The trolley reducer 142 drives the gear pair to drive the trolley traveling roller 15 at the bottom of the trolley end beam 13 to move linearly along the rail steel 11 and run to the top of the material handling station where the frozen product 8 is to be transferred. The trolley drive motor 231 drives the trolley reducer 232 to rotate, which drives the connecting shaft 233 and sprocket 235 assembly to rotate synchronously. The two sprockets 235 on both sides drive the two sets of traction chains 234 synchronously. The two ends of the traction chains 234 pull the chain fixing seats 236 on both sides of the trolley end beam 22 respectively, so that the trolley traveling roller 24 at the bottom of the trolley end beam 22 moves linearly along the rail steel 11 at the top of the trolley main beam 12 and runs to the top of the frozen product 8. The electric hoist 31 on the main beam 21 of the trolley starts to release the rope. The two steel wire ropes 32 on the electric hoist 31 are released synchronously, driving the clamping module 4 to descend smoothly in the vertical direction. During the descent, the stabilizing component moves down with it and at the same time constrains the clamping module 4 to suppress horizontal swaying and swinging, ensuring that there is no tilt or deviation during the descent. After the clamping module 4 descends to the set clamping height, the electric hoist 31 stops releasing the rope and brakes. The clamping cylinder 43 extends outward, pushing the clamping rod 441 to rotate. The nail teeth 442 on the clamping rod 441 simultaneously press inward and embed into the frozen product 8 to achieve rigid clamping. After the frozen product rises to a certain height from the frozen product loading plane, the protective cylinder 451 extends outward, pushing the protective connecting rod 452 to rotate, causing the protective support plate 453 to close inward, supporting the frozen product 8 below and to the side, forming secondary anti-fall protection. After the clamping and protection actions are completed, the electric hoist 31 reverses the rope and the two wire ropes 32 pull upwards synchronously, driving the clamping module 4 and the frozen product 8 to rise steadily in the vertical direction to the safe hoisting height. The stabilizing module 5 moves upwards and continuously provides guidance and anti-sway constraints. Subsequently, the large trolley module 1 and the small trolley module 2 work together to move to the target placement position, and then the large trolley module 1 and the small trolley module 2 brake and lock at the same time. When the electric hoist 31 starts to release the rope, the clamping module 4 drives the frozen product 8 to descend vertically. When it approaches the placement surface, the protective cylinder 451 is first controlled to exhaust and retract, which drives the protective support plate 453 to fully open outward to avoid the placement space. Then, the electric hoist 31 releases the rope slightly. After the frozen product contacts the placement surface, the clamping cylinder is controlled to exhaust and release pressure, which drives the clamping rod 441 to rotate in the opposite direction to reset. The nail teeth 442 disengage from the frozen product 8, releasing the clamping state and allowing the frozen product 8 to fall smoothly into the designated position.

[0071] After the material is unloaded, all components are reset, or the machine moves directly to the next material handling station to begin the next work cycle.

[0072] This invention primarily designs a frozen food transport device. By installing a bridge at the top, ground space is freed up, and by using a clamping module 4, manual labor is eliminated. A crank assembly prevents swaying of the frozen food 8 when the steel wire rope 32 is lifting and lowering it, while also providing guidance. A rotating assembly 7 enables the transport of the frozen food 8 in any direction. Spike teeth 442 ensure stable clamping of the frozen food 8, and a protective assembly further prevents the frozen food 8 from falling during transport.
