ORBITER H is a triple pulley with rotating conical sides made of aluminum alloy. The running surfaces are mounted on ball bearings. The three chambers protect the ropes from wear due to mutual friction. Two carabiners can be attached in the upper opening. ORBITER H is ideal for the construction of pulley systems with a max. transmission ratio of 6 to 1. The pulley is suitable for ropes with a diameter = 13 mm.
