Tensioning device for pairs of cables - which form closed loop and are driven by electro-motor with two drums that adjust tension in cables

摘要

The tensioning device consists of two drums (5) rotating about a shared axis and driven by a shared electromotor (19). The cables (1, 2) from the drums pass around diametrically opposite wheels (30) mounted at the end of lateral arms attached to the shared stationary spindle of the drums. The motor is supplied with electricity via wires within the cables or from a battery built into the device.
