Definition - What does Pneumatic Jack mean?
Pneumatic jacks employ compressed air to transfer forces for the purpose of lifting, pushing or moving heavy machinery or material. Pneumatic power turns electric power into mechanical power with the help of compressed air. Various kinds of pneumatic tools are used in different facets of the construction industry from jack hammers to jacking systems. Pneumatic systems are easy to use and are economical because ordinary air is primarily used which is easily available. In trenchless technology such as pipe ramming, jacks are used for the purpose of lifting heavy pipes, positioning them for installation an jacking them forward during the installation process.
Trenchlesspedia explains Pneumatic Jack
Pneumatic systems typically consist of a pneumatic cylinder, compressor, jack, and a control unit. To make the air to perform better, some of the water vapor is removed and a small amount of atomized oil is added. The compressor compresses the air and passes it to the pneumatic cylinder fitted with a piston, where the change of force takes place from electrical power to mechanical motion. The electrical power is controlled and supplied from the control unit with a solenoid valve. The load can be moved or lifted depending on the type of jack being used. Pneumatic powered jacks and other systems are becoming a favored choice because it is fast, works better with hand driven equipment, and is cost effective.
