Doughty Heavy Duty Pulleys

These heavy duty pulleys have been completely redesigned. The sheaves are constructed of MOS 2 Nylon with ball races for smooth friction free operation. The side plates are 5mm thick steel to provide an immensely strong construction. The design has been tested to a stringent 10:1 ratio. As standard, the blocks are made up from single, double and triple sheaves with the quadruple being assembled from two doubles. Five way blocks are made from a triple and a double. Should you require your sheaves to operate in reverse directions please phone us and we will advise on a way of achieving your objective. To order, firstly choose your basic block then select one of the fittings
shown alongside for each of your basic blocks.

It is best to place your order like this:
Please supply: 2off DOUT42901 c/w DOU42990
The fittings will then be supplied fitted to the correct blocks. We can, of course, supply the fittings and blocks as separate items.

Never exceed the manufacturers safe working loads.
