2. Description of the Related Art Generally, in a self-propelled light-duty carrier, since a vertical wall of a control box for partitioning the platform and the control section is provided between the platform and the control section, a warehouse, etc. When loading and unloading the cargo boxes placed on the shelves on the carrier bed, or when loading the cargo boxes loaded on the cargo carrier on the shelves, the worker shall descend from the control section to perform work. there were.

[0003]

When working in a narrow aisle in which many shelves are arranged side by side, the loads placed on the left and right shelves are loaded and unloaded on the bed, and the aircraft is moved a little to get the loading and unloading. In addition, since the machine body must be moved and the work must be repeated in order, that is, the work must be repeated frequently to and from the vehicle body, resulting in poor work efficiency. An object of the present invention is to improve work efficiency in a narrow passage in which many shelves are arranged in parallel.

[0004]

A characteristic configuration of the present invention for achieving the above object is that an opening for working is provided at the center of a vertical wall provided between a control unit and a cargo bed. is there.

[0005]

When working in a narrow aisle where many shelves are arranged side by side, the operator takes out the luggage placed on the left and right shelves while riding on the control section, It can be loaded on the loading platform through the work opening provided in the center of the vertical wall with the loading platform.

[0006]

As a result of the above construction, the worker can lift the cargo bed and load the cargo while being positioned in the control section, and the work efficiency can be improved.

EXAMPLE FIG. 1 shows a self-propelled light luggage carrier.
This light-duty carrier has a platform 1 that can be lifted and lowered at the front of the vehicle body.
And a control unit A at the rear of the vehicle body, and at the lower part of the vehicle body frame 2, a pair of left and right drive rear wheels 3, 3 and a pair of left and right caster wheels 4, 4 rotatable about the longitudinal axis. Is equipped with. As shown in FIG. 3, the pair of left and right drive rear wheels 3, 3 are respectively connected via an electric motor 6 having a built-in negative brake that operates by cutting off the power supply, and a transmission device in a deceleration case 7. It is configured to be drivable, and runs straight by the same speed drive of the left and right electric motors 6, 6.
In addition, the left and right electric motors 6, 6 are configured to be able to be driven to rotate by a speed difference. As shown in FIG.
Is configured to be able to move up and down through an elevating link mechanism 8 that is installed in an X shape between the elevating link mechanism 8 and one of the elevating link mechanisms 8 and one end side of one link 8a of the elevating link mechanism 8 is provided on the body frame 2. A guide frame 1 pivotally connected to the frame 2a, and one end side of the other link 8b provided on the carrier 1.
The links 8a and 8b are pivotally connected to each other, and the other ends of the links 8a and 8b are slidable along the guide frames 1a and 2a. Then, by swinging a link 8a pivotally connected to the vehicle body frame 2 via an electric cylinder 10 driven by an electric motor 9, the loading platform 1 can be moved up and down.

As shown in FIG. 1, the control section A includes a handle 11 for getting on and off and a lift lever 1 for a loading platform on one lateral side of the vehicle body.
2, high / medium / low speed shift switches SW _1, SW _2, SW ₃ ,
A joystick lever 1 for arranging a control tower 17 equipped with a battery level meter 14, a charging outlet 16 and the like, and for moving the vehicle forward and backward and turning left and right on the other side
A control panel 19 provided with 8 is distributed and arranged, and an operation opening 21 for opening the upper part is provided at the center of the vertical wall 20a of the control box 20 on the cargo bed side. A battery 5 and a controller 15 are arranged inside the control tower 17, a work lamp 22 is further provided on a side portion of a vertical wall 20a of the control box 20 on the side of the loading platform, and a boarding / alighting operation of the control box 20 is performed. A plate 24 for backrest that is swingable around the front-rear axis is provided in each of the operation openings 23. A safety pedal 13 is provided on the floor of the control section A, which can turn off the electric power to the electric motors 6 and 6 for the rear left and right wheels by an operation of the pedal when the aircraft is in an emergency stop.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the configurations of the accompanying drawings by the entry.
