Two single-stage jacks were manufactured for an indirectly operated hydraulic elevator as part of a drive system modernization project. At a Bavarian automotive plant, vehicle parts with a maximum payload of 15,000 kg are transported 40 m by a triple-stage unit with a frequency-controlled drive from ALGI. The two jacks, with a piston diameter of 285 mm and a length of 20 m, will be lowered into the shaft by crane tomorrow morning.
