AI Technical Summary
During the travel of existing cranes, the hook is prone to large swings, which makes it difficult to clamp the object and may cause it to collide or fall off.
By setting a limiting plate and a connecting rod structure inside the lifting frame, and using a motor to drive the threaded rod and connecting rod to move the slider, the swaying of the limiting plate is reduced. At the same time, rollers and a gear system are installed on the hook to reduce friction and achieve stable movement.
It effectively reduces the sway of the hook, improves the stability of the limit plate, and reduces the friction of the hook when moving, ensuring the smooth clamping and transportation of items.
