The Lift-It confined space 4:1 pulley set combines double pulleys with a progress capture in order to raise and lower a load. The two double pulleys create a 4:1 mechanical advantage system so the user only has to pull 25% of the weight of the load.

When lifting with the cam engaged, the rope will be held in place if the user releases their grip on the rope. When the cam is disengaged, allowing the rope to slide through the pulley system lowers the load.

Note: Although each component used in the confined space pulley system has the appropriate EN certification, since this system is assembled from components it is not certified as a complete system. It is up to the user to determine appropriate safety margins.
