The invention discloses a hand-operated elevator capable of achieving fault emergency stop. The hand-operated elevator comprises an elevator body, a lifting cavity with an upward opening is formed inthe elevator body, a lifting column capable of moving up and down is arranged in the lifting cavity, the upper end face of the lifting column extends to the outer side of the upper portion of the elevator body, a lifting platform is fixedly arranged on the upper end face of the lifting column, and a rotary connecting shaft is fixedly arranged on the lower side of the left end face of the lifting platform. According to the hand-operated elevator, the elevator is driven to ascend and descend through hand cranking, the energy-saving effect is achieved, the hand-operated elevator is light and convenient to move, kinetic energy does not need to be provided by a motor, work is very convenient, and the fixed position of the elevator after positioning is combined with tire braking at the same time, so that the stability of the device is obviously improved; and the stability of the lifting platform is high, some device fault problems can be solved, the effect of sudden stop and slow descendingcan be achieved instantly in the emergency falling process of the lifting platform, and the safety coefficient of workers is increased.

    本发明公开的一种能故障紧急停止的手摇式升降机,包括升降机体,所述升降机体内设有开口向上的升降腔,所述升降腔内设有能上下移动的升降柱,所述所述升降柱上端面延伸至所述升降机体上方外侧并固定设有升降台,所述升降台左端面下侧固定设有转动连轴,本发明通过手摇带动升降机升降达到了节约能源的效果,且本发明移动轻便且不需要电机提供动能使工作非常方便,对于升降机的定位后的固定位置与轮胎刹车同时结合,使装置的稳定性明显提高,并且本发明升降台的稳定性高,在能克服一些装置故障问题,在升降台紧急掉落的过程中能瞬间做到急停缓降的效果提高了工人的安全系数。
