What are the structural components of the hook group
Hook group consists of two parts: hook and roller slide group. There are two common hook groups, namely short hook and long hook.
The long hook group uses ordinary hooks. The hook is supported on the hook beam and the moving pulley is supported on a separate pulley shaft. When used, it will reduce some effective lifting height. The short hook group uses a long hook, and the moving pulley is directly installed on the hook beam. Since a separate pulley shaft is eliminated, the overall height is smaller, which increases the effective lifting height accordingly. The pulleys of the short hook group are installed on both sides of the hook, and the number of pulleys is even. They are suitable for pulley groups with smaller magnifications. When the magnification is large, the number of pulleys increases and the hook beam increases, which will make the hook group weigh too much. Therefore, the short hook set is only used for cranes with smaller loads.
For the convenience of hooking, the hook is required to be able to rotate about the vertical and horizontal axis. Therefore, the hook must be supported on the hook beam with thrust force, and the nut at the tail of the hook is pressed on the thrust bearing. The hook beam of the short hook group is the rotation shaft. The hook beam of the long hook group has an annular groove where the shaft end is matched with the fixed shaft baffle, allowing the beam to rotate; while the shaft end of the pulley group above is a flat notch, which does not allow the pulley shaft to rotate.
The above is the structure of the hook group and the two common types of hook groups.
