Zinko Ratchet Jacks are the most versatile general-purpose jacks available. Rugged construction permits safe, efficient lifting, lowering, skidding, moving, sustaining and leveling with full capacity on the toe or on the head. Cannot be tipped under load. Safety speed trigger can be tripped only when NOT under load. The lever and fulcrum principle is applied in this simply constructed, fast-acting jack. Downward stroke of the lever rises bar one notch at a time and the pawls spring into position, automatically holding the load and releasing the lever for the next lifting stroke.
