3.5 Ton In-Floor Full Rise Scissor Lift

The CAV J-35 is a premium in-floor scissor lift designed for workshops that value both functionality and workplace aesthetics. Its flush-mounted, in-floor configuration is one of its most distinctive features. When the lift is in its lowest position, the platforms sit perfectly flush with the surrounding concrete floor, creating a smooth, unobstructed surface across the entire workshop bay. This design eliminates the trip hazards associated with above-ground lift bases and allows vehicles, floor jacks, and tool trolleys to roll freely over the lift area when it is not in use. The clean, integrated appearance also gives the workshop a more professional and organized look, which can be an important consideration for customer-facing facilities.

The J-35 delivers a maximum lifting height of 2150mm, providing full standing clearance for technicians working underneath the vehicle. This full-rise capability makes the lift suitable for a wide range of repair and maintenance tasks, from brake and tire work to more involved underbody inspections and component replacements. The platforms measure 550mm in width and can be extended from 1540mm to 1700mm in length, allowing technicians to adjust the platform configuration to suit vehicles with different wheelbases. The distance between platforms is also adjustable from 800mm to 850mm, providing further flexibility for positioning the lift under various vehicle chassis designs.

The lifting system is powered by a 2.2kW motor and features hydraulic synchronization to ensure both platforms rise and fall in perfect unison. This synchronization is a critical engineering detail that avoids unexpected unevenness between the platforms, which could cause instability or make it difficult to position the vehicle securely. The lift reaches its full height in 50 to 60 seconds, a steady and controlled pace that allows for smooth operation. The mechanical safeties are operated pneumatically, engaging and releasing through an air supply system that requires 6-8Mpa of pressure. These safeties provide reliable mechanical locking at multiple points throughout the lifting range, giving technicians confidence that the platforms will hold their position even if hydraulic pressure fluctuates.

Safety features on the J-35 are comprehensive and thoughtfully integrated. The automatic stop at maximum lifting height protects the lift from over-extension, shutting off power to the motor once the designated top position is reached. This feature preserves the integrity of the hydraulic cylinders and the scissor mechanism over the long term. An overload valve is included in the hydraulic system, which halts lifting operations if the weight on the platforms exceeds the rated 3.5-ton capacity. The lowering speed control valve regulates the descent rate, ensuring the platforms lower smoothly and steadily rather than dropping too quickly. All operations are managed through a 24V push-button control system, which operates at a low voltage for enhanced operator safety. Four lifting pads are included with the lift, protecting the vehicle's jacking points from direct metal contact.

Product highlights

Flush-Mounted, In-Floor Design

The flush-mounted, in-floor design of the CAV J-35 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. This is particularly valuable in busy workshops where every square meter of floor space needs to be utilized effectively.

Hydraulic Synchronization for Level Lifting

The hydraulic synchronization system on the J-35 ensures that both platforms move in perfect harmony during lifting and lowering. This is a critical feature for stability and safety, as uneven lifting can cause a vehicle to shift or become unstable, particularly if its weight distribution is not perfectly balanced. The synchronization system automatically compensates for any minor variations in hydraulic pressure, keeping the platforms level throughout the entire travel range. This engineering detail gives technicians confidence that the vehicle will remain stable and secure during every operation.

Pneumatic Mechanical Safeties

The mechanical safeties on the J-35 are operated pneumatically, meaning they engage and release through compressed air rather than manual levers or complex electrical actuators. This pneumatic engagement provides a positive, reliable locking action that holds the platforms securely at the selected working height. The mechanical nature of the locks means they are not dependent on hydraulic pressure to maintain their hold, so the platforms will stay in position even if hydraulic pressure is lost. The air-operated release makes lowering smooth and controlled, allowing technicians to manage the descent with precision.

Comprehensive Safety Protection Systems

CAV has equipped the J-35 with multiple independent safety systems that work together to protect both the operator and the equipment. The automatic stop at maximum lifting height is a simple but effective safeguard that protects the lift from over-extension, which could otherwise damage the hydraulic cylinders or the scissor mechanism. The overload valve provides load protection, halting lifting if the rated capacity is exceeded. The lowering speed control valve ensures a smooth, controlled descent, preventing the platforms from dropping too quickly and potentially jarring the vehicle or causing injury. These three systems address different failure scenarios, providing layered protection that enhances overall workshop safety.

24V Low-Voltage Control System

The J-35 uses a 24V push-button control system for all lifting and lowering operations. This low-voltage design is a thoughtful safety consideration, as it reduces the risk of electrical shock in a workshop environment where technicians may be working with tools and equipment that are grounded or wet. The 24V system is also compatible with a wide range of workshop electrical setups, making installation more straightforward. The push-button controls are intuitive and easy to use, allowing technicians to operate the lift confidently even with limited training.

Extendable and Adjustable Platforms

The platforms on the J-35 are designed with flexibility in mind. They extend from 1540mm to 1700mm, accommodating vehicles with different wheelbases, from compact cars to larger sedans and SUVs. The distance between the platforms is also adjustable from 800mm to 850mm, allowing technicians to position the platforms to match the vehicle's chassis width. This adjustability makes the J-35 a versatile lift that can handle a wide variety of vehicle types without the need for adapters or additional accessories.
