Tractel Griphoist

Increase the capacity of the GRIPHOIST-TIRFOR

The lifting and pulling power of GRIPHOIST-TIRFOR winches can be greatly increased by the use of multiple sheave blocks. These can increase the nominal capacity of the GRIPHOIST-TIRFOR machine by 2, 3 or 4 times or more (see diagram below). For most applications, an allowance must be made for friction in the sheaves. Ensure that the capacity of the blocks, fittings and anchor points are suitable for the load. When using the GRIPHOIST-TIRFOR for pulling purposes, it should be remembered that the necessary pulling effort is not equal to the weight of the load to be moved. It should be calculated.
