*250, 500 & 750 Kg Lifting capacity based on the recomended wire rope (sized) with a nominal factor of safety of 5:1. For theatre applications an 8:1 factor of safety on wire ropes is generally required. For the application and required factor of safety required see table below.
Note. Prior to wire rope selection, consider the rope construction for flexibility and verify that the MBL (minimum braking load) of the rope (for single rope attachment) equates to and provides the required factor of safety for the application.
