Pronal lifting Bags are pneumatic devices especially designed and shaped to perform mechanical functions such as pushing, pressing, guiding, clamping, blocking, damping, lifting and moving.

They are ruggedly constructed from high-resistance fabric coated with synthetic rubber formulated for industrial environments.

Offering perfect distribution of thrust, they are normally inflated with compressed air or other fluids such as water, oil and glycol (depending on the application).

Lifting bags are easy to integrate into conventional mechanical systems. Typical applications include presses, moulds, conveyors, handling robots and lifting tables.

Pronal lifting bags differ from Pronal's highly portable lifting cushions in that they are typically fixed and custom-shaped to particular tasks.
