Vehicle Restraints
Once the lorry backs to the position of loading / unloading, its tail end will touch and press down the entire steel frame with a built-in spring to allow it to back-up completely against the steel frame. Then the operator presses the control button to hoist up the hook and hook the cross-bar of the lorry tail; The hook could bear a force as high as 16,000Kg. The locking device will also automatically adjust the fixing condition with the cross-bar of the lorry bar to ensure safety per the floating height of the lorry tail during loading and unloading. After the loading or unloading is finished, the operator will press the button again to release the hook. If the lorry deviates from or the cross-bar of the lorry tail isn't at the effective locking position, the locking device will be under wrong working conditions. Then, the alarming device will sound an alarm and warn the operator that the lorry isn't locked normally.
