4 Ton In-Floor Alignment Scissor Lift

The CAV SA-4.0U is a premium in-floor alignment scissor lift engineered for workshops that demand both precision and power. Its flush-mounted, in-floor installation is one of its most practical features. When the lift is retracted, the platforms sit level with the surrounding concrete floor, creating a smooth, obstruction-free surface across the entire bay. This design eliminates trip hazards, allows vehicles to be driven over the lift area without obstruction, and gives the workshop a clean, professional appearance. The 4500mm platform length provides generous support for a wide range of vehicles, from compact hatchbacks to full-size sedans, SUVs, and light commercial vehicles.

The SA-4.0U delivers a maximum platform lifting height of 1700mm, providing comfortable standing clearance for a wide range of under-vehicle tasks. 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 50 to 60 seconds. The air operated single-point lock release system allows the operator to disengage the safety locks from a single convenient point, simplifying the lowering procedure and reducing operator fatigue. Multiple locking positions throughout the lifting range provide secure mechanical support at various heights, allowing technicians to choose the most comfortable working position for each specific task.

What truly sets the SA-4.0U apart as an alignment lift is the built-in slip plates. These plates allow the vehicle's wheels to move laterally during alignment adjustments, enabling precise toe, camber, and caster measurements. This built-in functionality eliminates the need for separate alignment accessories or portable slip plates, saving both setup time and workshop space. For workshops that require full alignment capability, turntables are available as an optional accessory, further expanding the lift's utility. The built-in secondary rise jack is another valuable feature that extends the lift's functionality. With a lifting height of 450mm, this secondary jack allows technicians to lift individual wheels off the platforms for tire rotation, brake work, or wheel removal. This feature eliminates the need for a separate floor jack when working on wheels and brakes, streamlining the service process. The jack is operated through the same pneumatic system, keeping the workspace uncluttered and the workflow efficient.

Product highlights

In-Floor Flush-Mounted Installation

The in-floor, flush-mounted design of the CAV SA-4.0U is a significant advantage for workshops that prioritize efficient use of space and workplace safety. When the lift is retracted, the platforms sit level with the concrete floor, creating a completely flat surface across the bay. This means there are no raised ramps or base plates for technicians to trip over, and vehicles can be driven or rolled over the lift area without any obstruction. The design also simplifies shop layout, as the lift does not consume valuable above-ground space when not in use. For customer-facing facilities, the clean, integrated appearance projects a professional image that can enhance the overall workshop experience.

Built-In Slip Plates for Alignment Precision

The built-in slip plates on the SA-4.0U are a core feature that transforms the lift into a dedicated alignment platform. These plates allow the rear wheels to move laterally as alignment adjustments are made, enabling the precise measurements needed for accurate toe, camber, and caster settings. The slip plates are integrated into the platform design, so there is no need for separate portable plates or adapters. This not only saves time during setup but also ensures consistent, repeatable results. For workshops that perform multiple alignment jobs each day, this built-in functionality is a significant productivity booster.

Air Operated Single-Point Lock Release

The air operated single-point lock release on the SA-4.0U simplifies the lowering process while maintaining reliable safety engagement. Instead of requiring the operator to release locks at multiple corners of the lift, the system centralizes the release mechanism into one easy-to-reach control point. This design reduces the complexity of the lowering procedure and allows the technician to maintain full control of the descent while keeping an eye on the vehicle and surrounding area. The pneumatic operation provides smooth, consistent engagement every time.

Built-In Secondary Rise Jack

The built-in secondary rise jack is a valuable feature that extends the SA-4.0U's functionality well beyond standard lifting. With a lifting height of 450mm, this secondary jack allows technicians to lift individual wheels off the platforms for tire rotation, brake pad replacement, and wheel removal. The jack is integrated into the lift's design, so there is no need for a separate floor jack or hydraulic jack stand. This built-in capability saves time, reduces the number of tools needed in the workspace, and keeps the workflow efficient. The jack is operated through the same pneumatic system as the main lift, making it easy to use and manage.

Multiple Locking Positions for Versatile Working Heights

The multiple locking positions built into the SA-4.0U give technicians the flexibility to choose the ideal working height for each specific task. For tire and brake work, a moderate height may be sufficient, while underbody inspections and suspension repairs might benefit from the full 1700mm of clearance. The ability to lock the lift at various heights also accommodates vehicles with different profiles, from low-slung sports cars to taller SUVs. This versatility means a single lift can serve multiple functions within the workshop, reducing the need for additional specialized equipment.

Large Diameter Cylinders for Powerful Lifting

The hydraulic lifting system on the SA-4.0U features large diameter cylinders that deliver powerful and reliable lifting performance. These cylinders provide consistent force throughout the lifting range, ensuring smooth operation even under heavy loads. The large diameter also contributes to the system's durability, as the cylinders are better able to withstand the stresses of daily professional use. The 3kW motor drives the hydraulic pump efficiently, providing the power needed for heavy daily use while maintaining smooth, controlled operation.

Optional Turntables for Full Alignment Capability

For workshops that require full alignment capability, the SA-4.0U can be equipped with optional turntables. These turntables allow the front wheels to pivot freely during alignment adjustments, enabling precise steering axis measurements. The turntables are designed to integrate seamlessly with the lift's platform, providing a professional alignment station that eliminates the need for separate alignment equipment. This optional upgrade allows workshops to expand their service offerings without investing in a separate alignment rack.
