The Ravaglioli U Series double scissor lifts, Nos. 535 and 540, are available in 7,000-lb and 9,000-lb capacities and are ALI/ETL certified. The hydraulic system uses advanced, twin-cross synchronization that consists of two hydraulic systems, which are cross-locked between each platform. The result is a synchronized lift without any cross beams between platforms. There is also a multi-position, pneumatically operated mechanical lock on each platform. The lifts have platform lengths that can be adjusted to lift the smallest car to light trucks and they have lift heights of 75". The 535 has a low-pickup height of only 3-7/8".
