Background

The full-electric carrier consists of several major components, including a lifting mechanism, a driving mechanism, an electric control component and a frame component. In the actual use process, the two paving auxiliary wheels are the most easily damaged for the stepping electric carrier, and the stepping electric carrier can be normally used if the paving auxiliary wheels are not arranged; however, when the truck is full, the line of sight is obstructed if the truck travels forward, and workers usually prefer to use the truck in a backward operation according to the actual needs (particularly in the case of an empty truck without an accessory for paving a balance wheel); at this time, the entire vehicle swings right and left as if it were a large penguin, and the carrier travels slowly and unstably.

In addition, the lifting mechanism consists of an oil cylinder power unit, a high-pressure oil pipe and a bridge circuit line.
