Motorised transport trolley with lift mechanism (CTME) -
These carts can move a load placed on a bench: the trolley enters below the bench, lifts it all, moves it all and sets the bench and the load back on the ground. You can watch it in this video: https://www.youtube.com/watch?v=IZVFg2PCmkY
The loading capacities of the standard versions are 5T or 10T.
They may receive their electrical supply through batteries, which afford them total freedom of work and movement. They may also be supplied from power grid.
Possible movements
The carriage is moved by two motorized wheels, and two or more freely rotating wheels.
The two motors can be activated in any of the two directions independently-differential-system via a keypad (or a remote radio options).
The vehicle moves in a straight line if the two motors are activated in the same direction, or tour, if only one engine is activated, or activated both in different ways.
