4 Ton On-Floor Alignment Scissor Lift

The CAV SA-4.0S is a thoughtfully engineered on-floor alignment scissor lift designed for workshops that need professional alignment capability without the disruption of in-floor installation. The surface-mounted design means the lift sits on top of the existing concrete floor, requiring no cutting, trenching, or major modifications to the workshop surface. This significantly reduces installation time and cost while still delivering the stable, reliable lifting performance that CAV is known for. The 4500mm platform length and 645mm platform width provide generous support for a wide range of vehicles, from compact passenger cars to full-size SUVs and light commercial vehicles. The 200mm minimum height allows most vehicles to drive onto the platforms easily, including those with moderate ground clearance.

The SA-4.0S delivers a maximum platform lifting height of 1750mm, providing comfortable standing clearance for a wide range of under-vehicle tasks including alignment adjustments, brake service, tire replacement, and suspension repairs. The hydraulic lifting system features large diameter cylinders that provide powerful and reliable lifting performance, driven by a 3kW motor that raises the lift to full height in approximately 60 seconds. This steady, controlled lifting pace ensures smooth operation and reduces the risk of load shifting during the lifting cycle.

What truly sets the SA-4.0S apart as an alignment lift is the built-in slip plates. These plates allow the vehicle's rear wheels to move laterally during alignment adjustments, enabling precise toe, camber, and caster measurements without the need for separate portable slip plates or adapters. This built-in functionality saves valuable setup time and ensures consistent, repeatable results. For workshops that require full alignment capability including front wheel steering measurement, turntables are available as an optional accessory. The air operated safety lock release system lets operators disengage the safety locks smoothly and reliably, while multiple locking positions throughout the lifting range provide secure mechanical support at various heights. The built-in secondary rise jack offers 350mm of additional lift for individual wheels, making tire rotation, brake work, and wheel removal faster and more efficient. The pneumatic release system operates at 0.6-0.8Mpa air pressure, delivering consistent engagement every time.

Product highlights

Surface-Mounted On-Floor Installation
Sits directly on existing concrete, requiring no cutting or trenching. Installation is faster and costs significantly less than in-floor alternatives. The design also allows relocation if workshop needs change.

Built-In Slip Plates for Alignment Precision
Enable rear wheels to move laterally during alignment adjustments for precise toe, camber, and caster measurements. Eliminates the need for separate portable plates that can shift during use.

Air Operated Safety Lock Release
Delivers smooth, consistent release action without the variability of mechanical cables. Requires less maintenance and reduces operator fatigue in busy workshop environments.

Built-In Secondary Rise Jack
Provides 350mm of additional lift for individual wheels, eliminating the need for a separate floor jack. Operates through the same pneumatic system as the main lift.

Multiple Locking Positions
Allows technicians to choose the ideal working height for each task, from tire and brake work to full 1750mm clearance for underbody inspections.

Optional Turntables
Enable front wheel steering measurements for full alignment capability. Integrates seamlessly with the lift platform without requiring a separate alignment rack.
