Method for ensuring and measuring the internal tension of an elevator hoisting rope, and elevator permitting the use of said method

摘要

The invention also relates to a method for ensuring the internal tightness of an elevator hoisting rope ( 9 ) in an elevator provided with hoisting ropes ( 9 ). According to the method, each hoisting rope ( 9 ) is tightened after installation of the elevator to a desired tightness by twisting the rope by the required number of turns in the twisting direction of the braiding, in such manner that the first end of the rope ( 9 ) remains fastened to its anchorage while the second end of the rope is free so as to allow tightening.
