The patented cam mechanism provides selectable lift cycles for optimized mechanical advantage—offering a standard 3/4″ stroke for rapid lifting or a 3/8″ ratchet cycle in low gear for increased leverage under heavy loads. This dual-mode design improves force efficiency, reduces operator strain, and ensures consistent performance in demanding service environments.
