Abstract

An elevator device where a reduction in the lifetime of the main rope is kept as small as possible even if the diameter of the drive sheave is reduced. The elevator device uses a hoist (10(10A)) having the drive sheave (9) with the diameter not more than 29 times as large as the diameter of the main rope, and at least an elevator car (1) and counterbalance weight (2) have rope sheaves (7a, 7b, 11 (12a, 12b)). The diameters of the rope sheaves (7a, 7b, 11 (12a, 12b)) are set greater than the diameter of the drive sheave (9).

Description

technical field [0001] The invention relates to an elevator installation having an elevator car which is raised and lowered in a hoistway. Background technique [0002] In the existing elevator equipment, the elevator car and the counterweight are connected by the main sling, and the main sling is wound on the driving pulley through the steering sheave, the elevator car and the sheave on the The driving pulley makes the elevator car and the counterweight go up and down. In the above-mentioned existing elevator equipment, in order to reduce the damage caused by the frictional drive to the main rope and reduce the bending resistance, etc., the general method is to make the driving pulley and the rope The diameter of the wheel is set to be 40 times or more the diameter of the main hanger. However, in recent years, a main hanger with improved bending performance has been developed by using synthetic fibers such as aramid and Kevlar. Rope, and the main hanger with longer service...
