Trucks portacables big and motorised: with engine of alternating current with variation of speed by converter of frequency
The design of the systems of the trucks portacables motorised developed by Vahle, distinguishes by his reliability and by the accurate manipulation of the cables. In concrete, even in bad meteorological conditions, such like storms, snow or rain, the system has showed his efficiency in cranes of transfer of containers. In his greater part, the maintenance limits to a periodic visual inspection.
