ABSTRACT:
A balance weight system for a unit includes a cylinder and a piston rod having a first end secured to the unit to move therewith. The piston rod further includes a second end with a piston head slidably received in the cylinder and separating the cylinder into a lower chamber for containing hydraulic oil and an upper chamber for containing air. A tank includes hydraulic oil contained in a lower part thereof and a working gas contained in an upper part thereof. A tube has a first end in the hydraulic oil in the lower part of the tank and a second end communicated with the lower chamber of the cylinder. The working gas exerts a pressure on the hydraulic oil to supply the piston rod with a force sufficient to uphold the unit. A motor is provided for moving the unit in a vertical direction.
