A crawler-type lifter comprises a lifter body; a crawler belt used for walking is fixed under the lifter body; a telescopic supporting frame is fixed to the edge of the lifter body; four lifting armsof the same structure are hinged to the lifter body; the lifting arms can extend upwards; connecting pieces are fixed to the upper ends of the lifting arms; all the connecting pieces can connect a working platform, and the working platform can be fixed; thelifting arms are divided into a lower arm, a middle arm and an upper wall from bottom to top, wherein the middle arm is sleeved in the lower arm and can slide relative to the lower arm, the upper arm is sleeved in the middle arm and can slide relative to the middle arm, and when the middle arm and the upper arm move upwards to the limit, thelifting arms can still keep supporting. The invention further discloses a pushing method using the crawler-type lifter. Compared with the prior art, the crawler-type lifter has the technical effectsthat the lifting arms are designed to be three-stage sleeve pushing, are not limited by hydraulic pressure, and can be pushed to a higher height, thereby meeting the market requirements.

    一种履带式升降机,包括车身,车身的下方固定用来行走的履带,车身的边缘固定伸缩支撑架,车身铰接四个结构一样的升降臂,升降臂能向上伸出,升降臂的上端固定连接件,所有的连接件都能将工作平台连接、且能完成对工作平台的固定;升降臂从下往上分为下臂、中臂、上壁,中臂套在下臂内且两者能相对滑动,上壁套在中臂内且两者能相对滑动,中臂、上壁向上运动到极限时,升降臂仍能保持支撑。本发明还公开了一种使用上述履带式升降机的推送方法。相对于现有技术,本发明的技术效果为,本发明升降臂设计为三级套管推送,不受液压的限制,能推送到比较高的高度,满足了市场需要。
