This FTF (Forest Traction Force) class 4.5 pulley series was produced to comply with DIN EN 17822 specifications for forestry ground traction. Double closure using threaded screw and split pin offers the highest safety factor as unintentional opening is impossible. Aluminium side plates and the polyamide sheave make the pulley a real lightweight. The large sheave diameter is particularly gentle on both plastic and steel winch ropes. The fitting for round slings allows space for both single and double use. The pulley's colour code and marking simplify selecting the correct equipment for the winch's tensile load.
