The Good Rigging Control System or GRCS is the ultimate tool for lowering heavy loads in a safe and controlled fashion. It provides a 44:1 and a 22:1 mechanical advantage for lifting heavy loads. It has a dead lift rating of 3,000 lb and a working load limit of 2,000 lb.
In this video we are rigging a large section of trunk wood extended over the water and boat house, showcasing the lifting capability of the GRCS.
