‘DUPLEX’ is a compact and lightweight double pulley device which has a pair of sheaves arranged in parallel.
The shape of its side plates is specially designed for use with a Prusik friction knot in progress capture systems, which simplifies the tasks of lifting loads and setting up polyspasts.
The pulley is mounted on a ball bearing for maximising working efficiency. High precision of manufacturing on CNC machines ensures significant minimisation of friction losses.
