This electric carriage is used to move small loads (up to about 400kg) in places not viable, where it is not advantageous building a stationary cable crane.
Following the idea of a cable crane in which the power and control signals are integrated into the traction cable, it was possible to develop a simple, lightweight and low cost carriage.
Is used an electric winch as traction element, which moves the carriage along the line.
The carriage is equipped with an electric motor, which moves the lifting hook. This engine is placed on the machine and is powered by the batteries on board. The batteries are recharged via an electronic charger positioned in the control cabinet, near the traction winch. By exploiting the conductivity of the traction cable can transmit the load from electrical cabinet up to the carriage batteries.
The cable crane is controlled by a transmitter. The receiver is mounted on the machine, which communicates with the electrical panel through conductors within the traction cable.
