To handle any type of load that is big and heavy when time-constrained these powered trolleys are used. In the case of a regular production cycle these transfer cars represent the best solution. To dispose of steering systems and greater powers for the same dimension and capacity load of the tired self-propelled trailers the cost for these transfer trolleys is lower. These power carts are most commonly used where there is crane work, buildings with store yards, the connection of equipment with department lighting bays, and an industrial building with several bays.
The self-propelled transfer cart is powered by a maintenance-free battery, cable, and diesel, and managed by a wireless remote controller or video panel. It can design and manufacture electric transfer trucks with various table sizes, loads, and functions.
