Изобретение относитс  к области испытаний транспортных средств, в частности к способам испытаний лиф- . тов и может быть использовано дл  измерени  т говой способности канатоведущего шкива лебедки лифта.This invention relates to the field of vehicle testing, in particular to methods for testing bodice. It can also be used to measure the pull capacity of the elevator winch pulley.

Наиболее близким техническим решением к изобретению  вл етс  способ измерени  т говой способности канатоведущего шкива лебедки лифта, заключающийс  в том, что измен ют нагрузку одной из ветвей до наступлени  проскальзывани  канатов в ручь х кана оведущего шкива и регистрируют величину этой нагрузки 1 .The closest technical solution to the invention is a method for measuring the traction capacity of the elevator winch driving pulley, which consists in changing the load of one of the branches before the rope slips in the runway pulley and records the value of this load 1.

Недостатком способа  вл етс  невысока  точность измерени  и большие трудозатраты..The disadvantage of this method is low measurement accuracy and large labor costs.

Цель изобретени  - повышен11е точности измерени  и сокращение трудозатрат при измерении.The purpose of the invention is to improve measurement accuracy and reduce labor costs during measurement.

Дл  этого производ т спуск противовеса кабины наего буферную пружину и регистрируют величину пружины на воздейст вие противовеса при равновесии системы кабина - противовес в момент начала проскальзывани  канатов в ручь х канатоведущегошкива и в момент полного ослаблени  нат жени  канатной ветви противовеса , причем т говую способность канатоведуцего шкива определ ют по величине дополнительной нагрузки, значение которой получают из следующей расчетной формулы:To do this, the cab counterweight of the buffer spring is lowered and the spring value is measured by the counterweight effect when the cabin – counterbalance system is balanced at the moment the ropes begin to slip into the cable driver’s lines and the tension of the counterweight rope is completely relaxed, and the rope-carrying pulley is determined by the value of the additional load, the value of which is obtained from the following calculation formula:
