AI Technical Summary

Technical Problem

Fully electric unmanned transport vehicles currently require manual lifting and lowering of cargo when transferring between vehicles of different heights, which is inconvenient and labor-intensive.

Method used

Installation of a pantograph-type electric lift system that mechanically moves cargo up and down on the top surface of the vehicle, operated by a commercially available electric remote control device.

Benefits of technology

Enables easy transfer of cargo between vehicles of different heights, reducing labor requirements and facilitating tasks such as fruit harvesting by raising storage containers to fruit height.

Abstract

To provide an electric pantograph type lift system device as a vertical movement device, which can transfer a load loaded on the top plate of a fully electric unmanned transport vehicle to another transport vehicle of a different height with a small amount of effort. [Solution] The electric pantograph lift system device has a base plate 1 for mounting the device on the top plate of a fully electric unmanned guided vehicle, and a top plate 2 for placing loads on it, with guide rails 1b and mounting brackets provided on the top surface of the base plate 1, and an electric piston 6 attached. Guide rails 1b and mounting brackets are provided on the underside of the top plate 2, and a pantograph assembly is rotatably attached to the mounting brackets of the base plate 1 and the top plate 2. An electric remote control device plate 5 is attached to the shorter side of either the base plate 1 or the top plate 2, and an electric remote control device is attached to the electric remote control device plate 5. Loads can be easily transferred to the loading platform of another transport vehicle of a different height with little force.
