AI Technical Summary
Traditional steel structure lifting equipment is not convenient for horizontal adjustment of the position of lifting components and is not convenient for overall movement, making it difficult to carry out lifting operations in designated areas.
A steel structure lifting device with a crawler-mounted walking mechanism, a geared motor, a servo motor, and an electric push rod was designed. The crawler-mounted walking mechanism enables the movement of the lifting device, the geared motor adjusts the angle of the lifting components, and the electric push rod adjusts the boom and the diagonal support legs to ensure the stability of the lifting device on uneven ground.
It enables convenient and stable lifting of the spreader in designated areas, and extends the service life of the spreader.
