ABSTRACT:
A rope traction device used as a winding instrument for a moving scaffold and other construction, loading and unloading and conveying machines, includes a sheave which is rotated by a motor through a speed reduction gear and around which a part of a traction rope is wound, and is movable along the rope by rotating the sheave. The sheave is provided with a rope groove formed by a pair of parallel and planar side plates substantially along the entire circumference of the sheave for receiving a part of the rope therein and resiliently pressing the rope on its side portions. The rope traction device includes an improved brake system according to which slots elongated in the circumferential direction are formed in each clutch member and each slot has a greater depth axially in the central portion thereof than in other portions. Steel balls are provided in the slots so as to be movable between the central portion and other portions of the slots so as to change the distance between the clutch members and thereby apply and release the brake.
