The invention provides a variable-amplitude trolley and a control method thereof.The variable-amplitude trolley comprises a frame, the frame comprises two force bearing beams arranged in parallel, a cross beam connected between the two force bearing beams and a pulley block supporting beam fixedly connected to the middle of the cross beam, and an anti-swing device is arranged at the bottom of the cross beam; and the anti-swing device is used for preventing the sling or the lifting hook from swinging or adjusting the angle of the lifted heavy object. According to the variable-amplitude trolley, the sling is prevented from swinging by arranging the anti-swinging device, the angle of a lifted object can be adjusted, the working efficiency is improved, and meanwhile potential safety hazards are avoided.
本发明提供了一种变幅小车及其控制方法,该变幅小车包括车架,所述车架包括两根平行设置的承力梁、连接在两根承力梁之间的横梁、固定连接在横梁中部的滑轮组支撑梁,所述横梁的底部设置有防摆动装置,所述防摆动装置用于阻止吊索或吊钩的摆动或调整所吊运重物的角度。本发明的变幅小车通过设置防摆动装置来防止吊索摆动,并且可实现对起吊物体的角度进行调整,不但提高了工作效率,同时避免了安全隐患。
