The invention discloses a crank type lift. The crank type lift comprises a crank type lift main body, fixed leg supports and an emergency landing structure, wherein one fixed leg support is arranged at each corner of a machine body of a crank type lift main body; the fixed leg supports are fixedly connected with the crank type lift main body in a welding manner; and the emergency landing structureis arranged on the surface of one side of an operation platform of the crank type lift main body and is fixedly connected with the operation platform by welding. The practical structure is reasonableand effective; and when the lifted operation platform cannot normally descend caused by machine faults, workers positioned on the operation platform can quickly return to the ground by using the emergency landing structure at the moment, so that possible peril incidents are avoided.

    本发明公开了一种曲臂式升降机,包括曲臂式升降机主体、固定脚支撑和紧急降落结构,所述曲臂式升降机主体的机身的四个角处各设置有一个固定脚支撑,所述固定脚支撑通过焊接的方式与曲臂式升降机主体固定连接,所述曲臂式升降机主体的作业平台的一侧表面设置有紧急降落结构,所述紧急降落结构通过焊接的方式与作业平台固定连接,本实用结构合理有效,在碰到机器故障导致抬升后的作业平台无法正常下降时,此时位于作业平台上的工作人员可以使用紧急降落结构快速返回地面,避免可能发生的危险事故。
