The crawler crane comprises a base, a connecting seat is rotationally connected to the lower wall of the base, two crawler wheels are connected to the two sides of the connecting seat, side plates are fixedly arranged on the side faces of the two crawler wheels, and two supporting seats are symmetrically and rotationally arranged on the two side plates; the four supporting seats are rotationally arranged on the side plates on the two sides through rotating rods, two rotating grooves corresponding to the rotating rods are symmetrically formed in each side plate, limiting mechanisms corresponding to the rotating rods are arranged in the four rotating grooves, and a control table is further fixedly arranged on the base. According to the principle that current can be generated when a closed loop wire cuts magnetic induction lines, the magnetic plate is remotely controlled to move up and down to control the current direction in the wire so as to control the change of magnetic poles on the iron core, so that the magnetic block is driven to rotate forwards or reversely to complete forward and reverse power transmission of the motor, and remote control over lifting of the cargo boom is achieved.
本发明公开了一种可远程操控的履带式起重机,包括底座,所述底座的下壁上转动连接有连接座,所述连接座的两侧连接设置有两条履带轮,两个所述履带轮的侧面均固定设置有侧板,两个所述侧板上均对称转动设置有两个撑座,四个所述撑座均通过转杆转动设置在两侧侧板上,两个所述侧板上均对称开设有两个与转杆对应转槽,四个所述转槽内均设有与转杆对应的限制机构,所述底座上还固定设置有控制台。本发明利用闭合回路导线切割磁感线会产生电流的原理,通过远程控制磁板上下移动来控制导线中电流方向来控制铁芯上的磁极变化,从而带动磁块进行正转或者反转完成电机的正反向输电,从而实现对起重臂升降的远程控制。
