The KPH370.50 standard version lift has two long two-stage and two shorter three-stage arms. The arm’s extensions slide on spring mounted rollers allowing easy use and a steady load. The LIKU version offeres EXTRA long three-stage arms ideal to lift long wheel base vehicles like the Ford Transit van and Mercedes Sprinter van. The 3rd extending member of each arm is constructed of solid steel (not a tube). This will maintain low arm height at rocker panels of cars without crushing/"biting" the panel. The lift design incorporates pulling pistons that allow the column and carriage to be more compact in shape offering more distance between columns without consuming more overall space. Pulling cylinders,although more expensive to produce,reduce stress on seals creating longer live. Other features of the KPH370.50 include:
