Lifting platform for vehicles has two operating pistons for a pump device guided coaxially therein for synchronised movement of two lifting surfaces

摘要

The at least two lifting surfaces (12, 13) which are movable by an associated hydraulic lifting device are associated with two operating pistons (10, 11)for a pump device which are guided coaxially in said pump device (16). The pump device has two coaxial pump cylinders in which the operating pistons are guided and which are biased by a pressurised medium.
