Unlike pneumatic and hydraulic cylinders, these jacks incorporate high-strength rubber and fabric diaphragms, meaning that they have no sliding components with gaskets; these makes Olmec pneumatic jacks totally reliable, strong and absolutely maintenance-free.

The internal telescopic system with a mechanical limit stop device ensures that the fixing plates cannot shift off balance or tilt. The patended pneumatic control system for easier jack descent without load, also guaranteeing totale retraction. All models are equipped with relief valve set at 10 BAR (143 P.S.I.) and a locking device to prevent the cylinder from descending during a pneumatic pressure loss.

Both the portable and wheeled versions are fitted with convenient grips allowing the lift/lower buttons to be operated at the same time.

Other key features of our jacks are their silent operation, the capability for operation in dusty environment and explosion risk, as well as on uneven surfaces, and rapid lifting response.
