They inflate with compressed air to create lifting force beneath a load.

They can. Hydraulic Rentals can supply complete pump kits including hoses, couplers, and gauges.

Flat jacks can be powered by hand pumps, electric pumps, air pumps, or gasoline hydraulic pumps depending on the application.

It depends on system size, but many systems can control multiple lift points across large structures.

Freyssi flat jacks are used for low-clearance hydraulic lifting and structural load transfer applications.

Yes. Knockout punching is one of the most common uses for hydraulic punch tools.

Selection depends on lifting capacity, clearance height, and equipment dimensions.

Center hole cylinders operate at a maximum working pressure of 10,000 PSI and are designed for use with compatible high-pressure hydraulic systems.

Two-speed pumps provide faster cylinder extension under low load, then switch to high-pressure output under load.

They can, but when used correctly they are designed to split the nut while minimizing stud damage.

Capacity varies by model, but many air lifting bags can lift several tons or more.

Because they are designed as engineered lifting cylinders rather than portable lifting jacks.
