The rope pulley with a hinged side panel and hook is designed for heavy-duty use, similar to the SRL-K rope pulley. The rope pulley is made entirely of metal with a painted finish. A major advantage of the rope pulley is its high-quality ball bearing. Thanks to the hinged side mechanism, the rope can be easily inserted, and a high-strength swivel hook is also included. The pulling force of the rope pulley is 40 kN, 64 kN, or 100 kN.
