摘　　要：曳引驱动电梯的空载曳引力试验是电梯监督检验和定期检验中都必须进行的试验项目,井道顶部空间不足、对重缓冲距离过大和曳引条件不符合都可能引发冲顶现象,本文介绍了在该试验中发生冲顶现象后的应对办法,以及如何判定冲顶的原因。The traction-driven lift＇s no-load traction test is a necessary test in the lift supervisory inspection and periodical inspection. The impaction can be caused by the top clearances for traction drive lifts, the buffer distance in the pit and the traction condition incompatible. This paper analyzes the reason of impaction in this test and puts forward some countermeasures to avoid the impaction.
