ことを特徴とする巻上下装置。 In construction machinery equipped with lifting objects that move along an erected leader, one end of the rope wound around a drive pulley driven by a hydraulic motor etc. is wrapped around a guide sheave and a sheave at the leader top. The rope is guided to the object to be lifted and lowered, and the rope is wound around one end to pull up the object, and the other end of the rope is wrapped around a guide sheave and a guide sheave at the lower part of the leader to guide the object to the object to be lifted and lowered. A hoisting/lowering device characterized in that an object to be lifted and lowered is pulled down by winding a rope on the other end side, and a tension pulley is provided at a predetermined position of the rope.
