INCREASE THE PULLING AND LIFTING CAPACITY
Umholi : Wire Rope Winches

The pulling and lifting capacity of Maxiwinch Wire Rope Winches can be increased greatly by use of sheave blocks inn various configurations. These can increase the nominal capacity of the winch by 2, 3 or more times (see illustration above).

Allowance must be made for friction in the sheaves. Always ensure that the capacity of the sheave blocks, anchor points and all fittings are suitable for the load.
