发明名称 Support leg moving apparatus and method
摘要 A support leg system for a dock leveler includes a support leg with a striker surface configured to engage a slider bar. When the striker engages the slider bar at a slow speed, the striker will slide down the slider bar and retract the support legs. However, when the striker engages the slider bar at a high rate of speed, the slider bar will deflect and cause the support legs to remain in a supporting position.
