对延深使用的提升机过卷现象进行了分析,从运动学角度指出造成过卷的主要因素及其消除的根本途径是控制过卷发生时的初速度。这对其它提升机也是适用的。 This paper analyzes the phenomenon of over hoisting of hoisting machine and points out the main factor of overreaching and the basic way to eliminate it from kinematic point of view is to control the initial velocity of overturning. This is also true for other hoists.
