Abstract

See full text

A counterbalancing arrangement and a method for counterbalancing two mutually movable parts, which is arranged to counteract the gravitational force of at least one of the movable parts. The counterbalancing arrangement includes a gas spring and a compressor system. The compressor system is designed to sense a pressure in the gas spring and to adjust the pressure if the pressure deviates from a predetermined value. The counterbalancing arrangement can be used for counterbalancing an industrial robot arm and is capable of maintaining its working capacity regardless of any gas leakage and variations in the ambient temperature so as to result in very few unwanted stops occasioned by a need for servicing the balancing spring of the counterbalancing arrangement.
