The invention relates to the technical field of lifting equipment, in particular to a heavy-load engineering lift truck which is characterized in that a controller and a lifting box body are arranged on a transport truck body, the lifting box body comprises an external copper protective cover and is provided with a bearing tray sliding up and down, and an abnormal speed detection assembly connected with the controller is arranged in the lifting box body; an electromagnetic part connected with the controller is arranged in the bearing tray, a tray bearing frame is arranged on the outer side of the bearing tray, and a traction assembly connected with the bearing tray is arranged on the upper portion of the lifting box and used for controlling the bearing tray to move up and down. The abnormal speed detection assembly detects an abnormal signal and sends the abnormal signal to the controller, the controller controls the electromagnetic part to be powered on to obtain magnetism, due to electromagnetic induction between the external copper protection cover and the electromagnetic part, resistance for high-speed descending or ascending of the bearing tray is generated in the external copper protection cover, and then the bearing tray is made to be stable and slow in speed.
本发明涉及升降设备技术领域,具体涉及一种重载工程升降车,运输车体上设置有控制器和升降箱体,升降箱体包括外置铜保护罩,升降箱体设置有上下滑动的承载托盘,升降箱体内设置有与控制器连接的非正常速度检测组件,承载托盘内部设置与控制器连接的电磁件,承载托盘外侧设置有托盘承载架,升降箱体上部设置有与承载托盘连接的曳引组件,曳引组件用于控制承载托盘上下移动,当承载托盘上下移动速度不正常时,非正常速度检测组件检测到非正常信号将其发给控制器,控制器控制电磁件通电获磁,由于外置铜保护罩与电磁件之间的电磁感应,外置铜保护罩内产生与承载托盘高速下降或者上升的阻力,进而使得承载托盘平稳缓速。
