Mechanical Lift Tables utilize springs and shock absorbers to assist in raising and lowering loads. Various spring options are available depending on the weight that will be handled in your specific application. Pneumatic Lift Tables utilize air bags to raise and lower loads. An air compressor will be required to inflate the air bags to the correct air pressure. A chart will be included with the purchase of the pneumatic lift table providing the recommended air pressure specifications depending on the load weight and required height of the platform.
