【摘要】 在电梯改造过程中常涉及到对轿厢的改造。从电梯曳引条件的角度 ,分析了常见电梯轿厢重量改变对曳引能力的影响情况。认为 :当轿厢与对重同时增加重量时 ,允许的载重量增加 ;当轿厢增加重量而对重不增加时 ,允许的载重量减少 ,且有打滑的可能 ;当轿厢与对重同时减少重量时 ,允许的载重量也将减少 ,亦有打滑的可能更多还原

【Abstract】 The influence on traction capability caused by the change of elevator car’s weight is analyzed in the terms of lift traction condition, for elevator rebuilding is always related to the car rebuilding. The conclusion that, when the weight of both elevator car and its counterpoise increases, the allowable load will enhance; while the weight of elevator car increases but not that of the counterpoise, the allowable load will decrease with likelihood of skidding; and when the weight of both elevator car and its counterpoise decreases, the allowable load will decrease with likelihood of skidding, is drawn.更多还原
