[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. [Example]

[0011] <Overall structure> FIG. 1 is an external side view of a crane 100 with an electric hoist according to a first embodiment.

[0012] The electric hoist crane 100 is installed in a building. As shown in FIG. 1, the electric hoist crane 100 includes a girder 10, a first traveling rail 11, an electric hoist 16, a crane saddle 20, a structure 40, and a recovery unit 60. In the following description, as shown in FIG. 1, the direction in which the girder 10, which will be described in detail later, extends is referred to as the X direction. The direction in which the first traveling rail 11, which will be described in detail later, extends and intersects (is perpendicular to) the X direction is referred to as the Y direction. The direction that intersects (is perpendicular to) the X direction and the Y direction is referred to as the Z direction.

[0013] <First running rail 11> The first traveling rails 11 are provided on structural members such as pillars of a building. The first traveling rails 11 are made up of a pair of first traveling rails 11a and 11b arranged opposite each other inside the building. The first traveling rails 11a and 11b extend parallel or approximately parallel to each other in the Y direction.

[0014] <Crane Saddle 20> The crane saddle 20 is provided so as to be able to travel on the first traveling rail 11. Specifically, the crane saddle 20 is composed of a crane saddle 20a provided so as to be able to travel on the first traveling rail 11a, and a crane saddle 20b provided so as to be able to travel on the first traveling rail 11b.

[0015] That is, the pair of crane saddles 20a, 20b are arranged so as to be able to travel on the pair of first traveling rails 11a, 11b. This allows the crane saddle 20 to travel along the Y direction, which is the direction in which the first traveling rails 11 extend. The traveling operation of the crane saddle 20 is controlled by a traveling inverter device 12. The traveling inverter device 12 is provided on the girder 10, which will be described later.

[0016] The crane saddle 20a has a saddle frame 21a and a first traveling mechanism 121a. The saddle frame 21a has a long side extending along the Y direction. The saddle frame 21a supports the first traveling mechanism 121a.

[0017] The first traveling mechanism 121a has a traveling drive wheel 25a and a traveling driven wheel 26a installed on the first traveling rail 11b, and an electric motor (motor) that rotates and drives the traveling drive wheel 25a. The traveling drive wheel 25a is rotatably supported via an axle 27a near one end of the saddle frame 21a in the Y direction.

[0018] The running driven wheel 26a is rotatably supported via an axle 28a near the other end of the saddle frame 21a in the Y direction. In the following description, the side in the Y direction where the running driven wheel 26a is provided is referred to as the +Y side, and the side where the running drive wheel 25a is provided is referred to as the -Y side.

[0019] The crane saddle 20b has a saddle frame 21b and a first traveling mechanism 121b. The saddle frame 21b has a long side extending along the Y direction. The saddle frame 21b supports the first traveling mechanism 121b.

[0020] The first traveling mechanism 121b has a traveling drive wheel 25b and a traveling driven wheel 26b installed on the first traveling rail 11b, and an electric motor (motor) that rotates and drives the traveling drive wheel 25b. The traveling drive wheel 25b is rotatably supported via an axle 27b near the end of the saddle frame 21b on the negative side in the Y direction. The traveling driven wheel 26b is rotatably supported via an axle 28b near the end of the saddle frame 21b on the positive side in the Y direction.

[0021] <Girder 10> The girder 10 extends in the X direction, i.e., in a direction intersecting the Y direction in which the first traveling rail 11 extends. The girder 10 is connected to a crane saddle 20a at one end in the X direction and to a crane saddle 20b at the other end in the X direction. Because the girder 10 is connected to the crane saddle 20a, the girder 10 is arranged so as to be movable along the Y direction in which the first traveling rail 11 extends.

[0022] In the following description, the side of the X direction where the crane saddle 20a is provided is referred to as the positive X side, and the side where the crane saddle 20b is provided is referred to as the negative X side.

[0023] The girder 10 is provided with a traveling inverter device 12, a second traveling rail 13, and a structure 40. An electric hoist 16 is also provided on the girder 10 so as to be able to travel on the second traveling rail 13. That is, the structure 40 includes the electric hoist 16. The girder 10 is connected to the electric hoist 16.

[0024] <Second running rail 13> The second traveling rail 13 is a rail along which an electric hoist 16 (described later) travels, and is connected to the girder 10. The second traveling rail 13 is composed of second traveling rails 13a and 13b that are arranged opposite each other in a pair on the girder 10. The second traveling rails 13a and 13b extend parallel or approximately parallel to each other in the X direction.

[0025] <Traction inverter device 12> The traveling inverter device 12 controls the movement of the crane saddle 20 described above. Specifically, the traveling inverter device 12 outputs a drive signal that indicates the direction and amount of rotation of the electric motors of the first traveling mechanisms 121a, 121b, based on a control signal output from an operation input device 3 of the electric hoist 16 described below. This causes the traveling drive wheels 25a, 25b to rotate, and the crane saddle 20 moves to the + side in the Y direction or the - side in the Y direction on the first traveling rail 11. As the crane saddle 20 moves, the girder 10 connected to the crane saddle 20 moves to the + side in the Y direction or the - side in the Y direction.

[0026] 1 shows the case where the traveling inverter device 12 is arranged on the wall surface on the +Y direction side of the girder 10. However, the traveling inverter device 12 is not limited to being arranged in the position shown in the figure, and may be arranged on the wall surface on the +Y direction side of the girder 10, for example.

[0027] <Structure 40> The structure 40 is provided on the above-mentioned girder 10. The structure 40 includes an electric hoist 16, a walkway 51, and a handrail 52.

[0028] <Electric hoist 16> As described above, the electric hoist 16 is disposed on the girder 10. Therefore, the electric hoist 16 can move in the Y direction together with the girder 10 in response to movement of the girder 10 along the Y direction. In addition, the electric hoist 16 can move relatively in the X direction on the second traveling rail 13.

[0029] The electric hoist 16 has a hoist 1, an operation input device 3, a crane hook 4, a hoist control unit 5, and a hoist frame 6. The hoist 1 is mounted on the hoist frame 6. The hoist 1 has, for example, an electric motor, a reducer, a drum around which a wire rope is wound, etc. One end of the wire rope is provided with a crane hook 4 for suspending a load.

[0030] The hoist frame 6 supports second traveling mechanisms 2a and 2b that cause the electric hoist 16 to travel on the second traveling rail 13. The second traveling mechanism 2a has a traveling drive wheel 14a arranged on the second traveling rail 13a, a traveling drive wheel 14b arranged on the second traveling rail 13b, and an electric motor that rotationally drives the traveling drive wheels 14a and 14b.

[0031] The traveling drive wheels 14a, 14b are rotatably supported on the hoist frame 6 via an axle 17a on the negative side in the X direction. The traveling drive wheels 14a, 14b are rotationally driven by an electric motor mounted on the hoist frame 6.

[0032] The second traveling mechanism 2b has a traveling driven wheel 15a arranged on the second traveling rail 13a and a traveling driven wheel 15b arranged on the second traveling rail 13b. The traveling driven wheels 15a and 15b are rotatably supported on the hoisting machine frame 6 via an axle 17b on the positive side in the X direction.

[0033] As a result, when the second running mechanisms 2a, 2b move on the second running rail 13, the hoisting machine frame 6 supporting the second running mechanisms 2a, 2b and the hoisting machine 1 mounted on the hoisting machine frame 6 can move along the X direction.

[0034] The hoist control unit 5 controls the operations of the hoist 1 and the second traveling mechanisms 2a, 2b in response to an operator's operation of the operation input device 3. Specifically, the hoist control unit 5 outputs a drive signal that indicates the direction and amount of rotation of the electric motor of the first traveling mechanism 2a in response to the operation of the operation input device 3. This causes the traveling drive wheels 14a, 14b to rotate, and the electric hoist 16 moves on the second traveling rail 13 to the +X side or the -X side.

[0035] The operation input device 3 accepts operations by an operator to operate the crane with electric hoist 100. The operation input device 3 outputs a control signal to the hoist control unit 5 or the traveling inverter device 12 in accordance with the operation performed by the operator. The operations that can be controlled by the operation input device 3 include movement of the crane hook 4 and the suspended load along the Z direction, movement along the Y direction, and movement along the Z direction. In the Z direction, the side where the crane hook 4 approaches the hoist 1 is defined as the +Z side, and the side where the crane hook 4 moves away from the hoist 1 is defined as the -Z side.

[0036] The operation of the crane 100 with electric hoist in response to the operation input device 3 is as follows.

[0037] When the operator operates to move along the X direction, the operation input device 3 outputs a control signal to the hoisting machine control unit 5. Based on the input control signal, the hoisting machine control unit 5 causes the second traveling mechanisms 2a, 2b to travel on the second traveling rail 13 toward the +X side or the -X side in the X direction. As a result, the hoisting machine 1 moves toward the +X side or the -X side together with the second traveling mechanisms 2a, 2b, and therefore the crane hook 4 and the suspended load move toward the +X side or the -X side in the X direction.

[0038] When the operator operates to move along the Y direction, the operation input device 3 outputs a control signal to the traveling inverter device 12. Based on the input control signal, the traveling inverter device 12 causes the first traveling mechanisms 121a, 121b of the crane saddle 20 to travel on the first traveling rail 11 toward the + side in the Y direction or the - side in the Y direction. As a result, the girder 10 connected to the crane saddle 20 and the electric hoist 16 arranged on the girder 10 move toward the + side in the Y direction or the - side in the Y direction. As a result, the crane hook 4 and the suspended load move toward the + side in the Y direction or the - side in the Y direction.

[0039] When the operator operates to move along the Z direction, the operation input device 3 outputs a control signal to the hoisting machine control unit 5. The hoisting machine control unit 5 drives the electric motor of the hoisting machine 1 based on the input control signal. This causes the drum of the hoisting machine 1 to rotate, and the wire hook attached to the drum is wound up or let out, so that the crane hook 4 and the suspended load move to the + side or - side of the Z direction. In other words, the load (suspended load) is moved up and down by the electric hoisting machine 16.

[0040] <Cloud Communications Department 37> As shown in Fig. 4, when an operator inputs a predetermined command from the operation input device 3, the traveling inverter control unit 34 housed in the traveling inverter device 12 controls the traveling inverter 35. The frequency, voltage, and current required for control are applied from the traveling inverter 35 to the traveling electric motors 47a, 47b, and at the same time, the traveling brakes 48a, 48b are controlled to be released, thereby moving the electric hoisting machine 16 in the X direction and -X direction along the girder 10.

[0041] Operation information for the electric hoist-equipped crane 100 in the X, -X, Z, and -Z directions is stored in the hoisting / traversing inverter control unit 31, and information for the Y and -Y directions is stored in the traveling inverter control unit 34. A cloud communication unit 37 is provided so that operation information for the X, -X, Z, -Z, Y, and -Y directions can be acquired and edited at a remote location without the need to go to the locations where the hoisting / traversing inverter control unit 31 and the traveling inverter control unit 34 are installed.

[0042] The cloud communication unit 37 acquires information about operation in the X direction, -X direction, Z direction, and -Z direction from the hoisting / traversing inverter control unit 31. Furthermore, operation information about the Y direction and -Y direction is sent from the traveling inverter control unit 34 to the hoisting / traversing inverter control unit 31 via the communication path 36.

[0043] The cloud communication unit 37 also acquires operation information for the Y direction and the -Y direction from the hoisting / traversing inverter control unit 31. The cloud communication unit 37 transmits the operation information for the X direction, -X direction, Z direction, -Z direction, Y direction, and -Y direction to a cloud server 38, which is a computer, via the Internet communication network 42.

[0044] Cloud server 38 stores operation information for the X direction, -X direction, Z direction, -Z direction, Y direction, and -Y direction, and transmits the information from server 38 to display terminal 41 when a request is received from display terminal 41. The operation information includes the movement speed and operation time of electric hoist equipped crane 100 in the X direction, -X direction, Y direction, and -Y direction.

[0045] Here, the information to be displayed on the display terminal 41 may be transmitted directly from the communication unit 37 to the display terminal 41 using short-range communication such as Bluetooth or Wi-Fi, without going through the Internet communication network 42. Examples of the display terminal 41 include a tablet terminal, a mobile phone (smartphone), and a PC.

[0046] The hoisting / traversing inverter device 31, the traveling inverter device 12, the cloud server 38, and the display terminal 41 may each be configured with hardware and software that includes a processing device such as a processor and a memory unit that stores programs, and the processing device reads and executes the programs to realize various functions.

[0047] <Sidewalk 51> The walkway 51 is a passageway through which workers walk when performing maintenance, inspection, etc. on the electric hoist 16. The walkway 51 is arranged along the side wall surface of the girder 10. Therefore, the walkway 51 extends along the X direction. In the Y direction, the walkway 51 only needs to have a width sufficient for workers to pass through. Note that the example shown in FIG. 1 shows a case in which the walkway 51 is provided on the side wall surface on the negative side in the Y direction of the girder 10.

[0048] <Handrail 52> The handrail 52 is provided on the walkway 51 to prevent workers from falling, etc. The handrail 52 is provided along the X direction in the Y direction (width direction of the walkway 51) on the side of the walkway 51 that is not in contact with the girder 10 (i.e., the negative side in the Y direction).

[0049] The handrail 52 has multiple posts 521 and a beam 522. The multiple posts 521 extend from the upper surface (the surface on the positive side in the Z direction) of the walkway 51 to the positive side in the Z direction. The multiple posts 521 are arranged at predetermined intervals along the X direction near the end of the walkway 51 on the negative side in the Y direction. The beam 522 extends in the X direction and is fixed to bridge over the upper ends (ends on the positive side in the Z direction) of the multiple posts 521. The length from the surface on the positive side in the Z direction of the walkway 51 to the beam 522, i.e., the height of the handrail 52 in the Z direction, is, for example, 90 cm or more. A collection unit 60, the details of which will be described later, is provided on the handrail 52.

[0050] <Collection Section 60> The collection unit 60 is fixed to the handrail 52, which is the structure 40. The collection unit 60 collects CO2 contained in the atmosphere around the electric hoist crane 100. As shown in FIG. 1, multiple collection units 60 are provided in a range R1 along the X direction in which the handrail 52 extends. Note that the multiple collection units 60 are not limited to being provided over the entire range R1 shown in FIG. 1, and may be provided in a part of the range R1. Alternatively, one collection unit 60 may be provided in the range R1 of the handrail 52.

[0051] The range R1 to which the recovery unit 60 is fixed is a rectangular surface whose long sides run along the X direction and whose short sides run along the Z direction, intersecting (perpendicular to) the Y direction. Therefore, the range R1 is located on the flow path of the airflow generated when the crane saddle 20 runs on the first traveling rail 11 and the electric hoist-equipped crane 100 moves along the Y direction. In other words, the recovery unit 60 is disposed on the flow path of the airflow generated by the travel of the crane saddle 20.

[0052] As shown in FIG. 1, the recovery unit 60 is arranged on the Y-direction side with respect to the sidewalk 51 and the handrail 52, that is, on the outside of the sidewalk 51 and the handrail 52. The recovery unit 60 arranged on the handrail 52 as described above includes a CO2 adsorbent 50 and a case 63 that detachably supports the CO2 adsorbent 50.

[0053] <CO2 adsorbent 50> The CO2 adsorbent 50 is fixed to the handrail 52 in a state of being housed in the case 53. The CO2 adsorbent 50 is processed into a filter shape in which an adsorbent substance processed into a powder or granular form is enclosed in a breathable pack, and absorbs and stores (adsorbs) CO2 contained in the surrounding atmosphere.

[0054] As an example of the adsorbent substance of the CO2 adsorbent 50, those that perform physical adsorption using zeolite or activated carbon, which are currently mainstream as carbon dioxide recovery and separation materials, can be mentioned. Further, as other examples of the adsorbent substance, those that perform chemical adsorption and absorption using an amine-supported inorganic porous body, supported activated carbon, etc., and chemical absorption carbonate systems such as Ca looping can be mentioned. However, the adsorbent substance and adsorption method of the CO2 adsorbent 50 are not limited to the above.

[0055] <Calculation of the adsorption amount of the CO2 adsorbent 50> On the display terminal 41, the CO2 adsorption rate and adsorption amount of the CO2 adsorbent 50 are displayed. Here, when the next inspection date of either or both of the annual inspection and the monthly inspection is approaching, the remaining number of days that can be adsorbed and an icon prompting attention to the tab may be displayed.

[0056] Also, the date of the previous CO2 adsorbent replacement and the predicted date of the next replacement are updated when the replacement is carried out. The replacement completion date is the date saved in the cloud server 38 when the checkbox is pressed during the replacement implementation, and the volume ratio of the CO2 adsorption amount is reset to 0% by pressing the checkbox.

[0057] The amount of CO2 adsorbed by the CO2 adsorbent 50 is calculated by the CO2 adsorption amount formula: CO2 adsorption amount (gCO2 / unit) = installation volume (m 3 ) × adsorbent density (kg / m 3) It is represented by (adsorption rate (gCO2 / kg / h) × moving time (h)).

[0058] Installation volume (m 3 ) and the adsorbent density (kg / m 3 ) are used to input and store the values of the installation volume of the CO2 adsorbent 50 mounted on the crane 100 with an electric hoist and the density of the CO2 adsorbent 50 at any timing in the calculation item column, and the input values are called and used during the calculation.

[0059] The adsorption rate (gCO2 / kg / h) and the moving time (h) are used to calculate the amount of CO2 adsorbed by the CO2 adsorbent 50 by using the moving speeds and operation times in the X direction, -X direction, and Y direction, -Y direction of the crane 100 with an electric hoist that the cloud server 38 transmits when receiving a request from the display terminal 41.

[0060] According to the above-described Example 1, the following operational effects can be obtained.

[0061] The crane 100 with an electric hoist includes a structure 40 including an electric hoist 16 that moves a load up and down, a girder 10 provided with the structure 40, and a recovery unit 60 that is fixed to the structure 40 and recovers CO2 contained in the atmosphere. The recovery unit 60 includes a CO2 adsorbent 50 that absorbs and stores CO2 contained in the surrounding atmosphere. Thereby, it is possible to adsorb CO2 present in the atmosphere around the crane 100 with an electric hoist.

[0062] <CO2 Adsorbent 50 Replacement Service> The replacement of the CO2 adsorbent 50 is performed when an alert is displayed on the display terminal 41 owned by the CO2 adsorbent 50 replacement vendor when the CO2 adsorption rate reached by prior agreement between the user of the crane 100 with an electric hoist and the CO2 adsorbent 50 replacement vendor is reached, and it is replaced.

[0063] The user is charged for the amount of CO2 adsorbent 50 used based on the amount of CO2 adsorption displayed on the display terminal 41 for each period agreed upon in advance between the user of the crane 100 with an electric hoist and the exchange company of the CO2 adsorbent 50. The fee based on the amount of CO2 adsorption is calculated as the amount of CO2 adsorption (gCO2 / unit) multiplied by the unit price for use (¥ / gCO2), and is notified to the user of the crane 100 with an electric hoist by the exchange company of the CO2 adsorbent 50.

[0064] Alternatively, a subscription system may be introduced in which the amount is fixed monthly or for any agreed period. In this case, multiple pricing plans are set up for users to choose from. The multiple pricing plans are set based on the replacement frequency of the CO2 adsorbent 50, the CO2 adsorption rate at the time of replacement, and the installed volume of the CO2 adsorbent 50, and the fee includes the cost of parts for the CO2 adsorbent 50, delivery charges, replacement costs, and technical support costs for inquiries. This allows users to have predictable and affordable expenses.

[0065] <Effects of Example 1> Because an electric motor is used to drive the electric hoist 16 and the crane saddle 20, the operation of the electric hoist crane 100 itself does not emit CO2. However, since CO2 is emitted at the power plant that supplies electricity when the electric motor is energized, it can be said that CO2 is indirectly emitted by the electric hoist crane 100.

[0066] In the first embodiment, as described above, the CO2 adsorbent 50 is adsorbed around the electric hoist crane 100 and the amount of adsorption is displayed on the display terminal 41, so that the CO2 adsorbent 50 can be replaced at an appropriate timing before the storage capacity of the CO2 adsorbent 50 reaches 100%. This makes it possible to reduce CO2 emissions resulting from the energization of the electric motor, i.e., the operation of the electric hoist crane 100. As a result, this contributes to carbon neutrality and the suppression of global warming.

[0067] Thus, the crane 100 with an electric hoist of the first embodiment includes a pair of crane saddles 20a, 20b arranged so as to be able to travel on a pair of traveling rails (first traveling rails 11a, 11b), a girder 10 connecting the pair of crane saddles 20a, 20b, a lateral rail (second traveling rails 13a, 13b) arranged on the girder 10 at a direction approximately perpendicular to the traveling rails (first traveling rails 11a, 11b), an electric hoist 16 arranged so as to be able to travel laterally on the lateral rail (second traveling rails 13a, 13b), a CO2 adsorbent 50 fixed to a structure 40 provided on the crane 100 and which recovers CO2 from the atmosphere by directly absorbing and storing CO2 contained in the surrounding atmosphere, and a learning device 70 (see FIG. 5) which estimates the amount of CO2 adsorbed by the CO2 adsorbent 50 based on a CO2 adsorption amount estimation equation that has been learned in advance using operating information of the crane 100.

[0068] An example of the configuration of the learning device 70 is shown in FIG.

[0069] As shown in Figure 5, the learning device 70 has a learning data storage unit 71 that stores learning data necessary for learning the CO2 adsorption amount estimation formula, a learning calculation unit 72 that reads the learning data from the learning data storage unit 71, learns and calculates the CO2 adsorption amount estimation formula, and outputs the CO2 adsorption amount based on the CO2 adsorption amount estimation formula, and a learning result storage unit 73 that stores the CO2 adsorption amount output by the learning calculation unit 72.

[0070] Here, the structure 40 is configured to include a walkway 51 and a handrail 52. The CO2 adsorbent 50 is fixed to the walkway 51 or the handrail 52. The learning device 70 estimates the amount of CO2 adsorption using the travel time and travel speed of the crane saddles 20a, 20b as operation information of the crane 100.

[0071] The learning device 70 is provided, for example, in the travel control unit (travel inverter control unit 34) of the crane saddles 20a, 20b.

[0072] The learning device 70 estimates the amount of CO2 adsorption using the installation volume of the CO2 adsorbent 50, the density of the CO2 adsorbent 50, the adsorption speed of the CO2 adsorbent 50, and the operating time of the crane 100. The learning device 70 estimates the adsorption speed of the CO2 adsorbent 50 from the moving speed of the CO2 adsorbent 50 using the rotation speed of the electric hoist 16, the diameter of the drive wheel, and the reduction ratio of the reduction gear. The learning device 70 estimates the operating time of the crane 100 from the rotation time of the electric hoist 16 for each moving speed of the CO2 adsorbent 50.

[0073] The crane 100 has a display unit that displays the amount of CO2 adsorption. The display unit is provided, for example, in at least one of the input device 3 that accepts operations for operating the crane 100, the travel control unit (travel inverter control unit 34) of the crane saddles 20a, 20b, and the traverse control unit (hoisting / traverse inverter control unit 31) of the electric hoisting machine 16.

[0074] The inspection assistance system for the crane 100 with an electric hoist has a server 38 that communicates with the crane 100 and has a learning device 70. The crane 100 transmits operation information of the crane 100 to the server 38, and the learning device 70 of the server 38 uses the operation information to estimate the amount of CO2 adsorption.

[0075] Alternatively, the inspection assistance system for the crane 100 with an electric hoist has a server 38 that communicates via a cloud communication unit 37 of the crane 100. The cloud communication unit 37 of the crane 100 transmits the amount of CO2 adsorption estimated by the learning device 70 of the crane 100 to the server 38.

[0076] In addition, in the inspection assistance system 100 for a crane with an electric hoist, the server 38 notifies the display device 41 that the CO2 adsorbent 50 needs to be replaced when the amount of CO2 adsorption exceeds a predetermined replacement capacity rate relative to the adsorption capacity of the CO2 adsorbent 50.

[0077] In addition, in the inspection assistance system for the crane 100 with an electric hoist, the server 38 accumulates the amount of CO2 adsorption per agreed period, and the CO2 adsorbent 50 exchange provider bills the user of the crane 100 for the usage fee for the CO2 adsorbent 50, which is determined according to the accumulated amount of CO2 adsorption per agreed period.

[0078] FIG. 6 is an example of a screen showing the CO2 adsorption amount information displayed on the display terminal 41. In FIG.

[0079] As shown in Figure 6, the screen displays the "Last adsorbent replacement date," "Current CO2 adsorption amount," "Current adsorption rate," "CO2 adsorbent replacement alert setting," and "Scheduled date for CO2 adsorption saturation."

[0080] FIG. 7 is an example of a screen displayed on the display terminal 41 to request replacement of the CO2 adsorbent material.

[0081] As shown in Figure 7, the screen displays "Replacement status," "Automatic periodic replacement service," "Desired replacement date," "Name of person in charge," "Telephone number," and "Email address."

[0082] FIG. 8 is an example of a screen showing previous information displayed on the display terminal 41.

[0083] As shown in Figure 8, the screen displays the "annual adsorption amount" and "replacement information" for a specific date. [Example]

[0084] In the first embodiment, the collection unit 60 is described as being disposed on the negative side in the Y direction with respect to the walkway 51 and the handrail 52, but the location of the collection unit 60 is not limited to this example.

[0085] FIG. 2 is a perspective view of the exterior of a crane 100 with an electric hoist according to a second embodiment.

[0086] As shown in Fig. 2, the recovery unit 60 is disposed on the + side in the Y direction with respect to the walkway 51 and the handrail 52, that is, on the inside of the walkway 51 and the handrail 52. The other configurations are almost the same as those of the crane 100 with electric hoist of the first embodiment shown in Fig. 1, and therefore a description thereof will be omitted.

[0087] According to the second embodiment, it is possible to obtain the same effects as those obtained by the first embodiment. [Example]

[0088] In the first embodiment, the collecting unit 60 is described as being arranged on the handrail 52 which is the structure 40 , but the collecting unit 60 may be arranged on another member of the structure 40 .

[0089] FIG. 3 is a perspective view of the exterior of a crane 100 with an electric hoist according to a third embodiment.

[0090] 3 shows a case where the recovery section 60 is fixed to the hoist frame 6 of the electric hoist 16 included in the structure 40. The other configurations are almost the same as those of the crane with electric hoist 100 of the first embodiment shown in FIG. 1, and therefore a description thereof will be omitted.

[0091] According to the third embodiment, it is possible to obtain the same effects as those obtained by the first embodiment.

[0092] The recovery unit 60 is fixed to the hoist frame 6 of the electric hoist 16 and is arranged in the flow path of the airflow generated by the movement of the electric hoist 16. As a result, an airflow is generated by the movement of the electric hoist 16, and the air around the crane with electric hoist 100 can be ventilated to the CO2 adsorbent 50 without stagnating. As a result, it becomes possible to efficiently adsorb CO2 in the atmosphere as the electric hoist 16 moves.

[0093] 3 shows the case where the recovery unit 60 is arranged on the + side in the X direction of the hoist frame 6, but the recovery unit 60 may also be arranged on the - side in the X direction of the hoist frame 6. Alternatively, the recovery unit 60 may be arranged on both the + side and the - side in the X direction of the hoist frame 6. Furthermore, the recovery unit 60 may also be arranged on both the hoist frame 6 and the main handrail 52.

[0094] Thus, in Example 3, the structure 40 is configured to include the electric hoist 16. The learning device 70 estimates the amount of CO2 adsorption using the traverse time and traverse speed of the electric hoist 16 as operation information of the crane 100.

[0095] The learning device 70 is provided in, for example, the traverse control unit (hoisting / traverse inverter control unit 31) of the electric hoisting machine 16.

[0096] The present invention is not limited to the details described in the above embodiments, and other embodiments that are conceivable within the scope of the technical concept of the present invention are also included within the scope of the present invention.

[0097] For example, instead of placing the recovery unit 60 on the handrail 53 or the electric hoist 16 of the structure 40, the recovery unit 60 may be placed on the walkway 51 of the structure 40. In this case, the recovery unit 60 may be suspended from the end of the walkway 51 on the negative side in the Y direction so that the adsorption surface of the CO2 adsorbent 50 intersects (is perpendicular to) the Y direction.

[0098] The crane with an electric hoist of the above embodiment comprises a structure including an electric hoist that moves a load up and down, a girder on which the structure is mounted, a CO2 adsorbent fixed to the structure that absorbs and stores CO2 contained in the surrounding air, and a learning calculation unit that calculates the amount of CO2 adsorption based on a CO2 adsorption amount estimation formula that has been learned in advance, and displays the amount of CO2 adsorption on a display unit.

[0099] According to the above embodiment, CO2 can be efficiently captured by replacing the CO2 adsorbent around the electric hoist crane at an appropriate time. By appropriately processing the captured CO2, it is possible to contribute to the prevention of global warming. [Explanation of symbols]
