Carriages are moved on the main cable with the help of the traction cable through the cable winch. The load to be transported is principally attached to the carriage and transported along the cable line.
Motorised skyline cranes are equipped with a motor to drive the lifting cable, which is wound on a drum on the carriage. The standard model is transported with a cable winch. Motorised skyline cranes are used above all on building sites.
