3.5 Ton On-Floor Double Scissor Lift

The CAV JB-35 is a professionally engineered on-floor double scissor lift designed to meet the demands of busy automotive workshops. Its double scissor configuration provides exceptional stability and lifting capacity, making it suitable for a wide range of repair and maintenance tasks. The lift is mounted directly on the workshop floor, which simplifies installation compared to in-floor designs while still delivering a low profile that does not create excessive obstructions in the workspace. The super low-profile design is one of the JB-35's most valuable features. With a minimum height of just 110mm, this lift allows even the lowest sports cars and vehicles with aggressive lowering kits to drive onto the platforms without the need for additional ramps or wooden blocks. This is a significant advantage for workshops that service performance vehicles or modified cars with reduced ground clearance.

The JB-35 is powered by an advanced electro-hydraulic system featuring four hydraulic cylinders that work together to deliver smooth and powerful lifting performance. This four-cylinder configuration provides more consistent power distribution compared to two-cylinder designs, reducing the risk of binding or uneven lifting. The 2.2kW motor drives the hydraulic pump efficiently, raising the lift to its maximum height of 1830mm in 50 to 60 seconds. This full-rise height provides ample standing clearance for technicians working beneath the vehicle, making the lift suitable for a wide range of under-vehicle tasks. The hydraulic synchronization system is a critical engineering feature that ensures both platforms rise and fall in perfect unison. This synchronization avoids unexpected unevenness between the platforms, which could otherwise cause the vehicle to shift or become unstable. The system automatically compensates for any minor variations in hydraulic pressure, maintaining level platforms throughout the entire travel range.

The JB-35 features air-operated safety locks that engage mechanically at multiple points throughout the lifting range. These locks provide secure, reliable support that does not rely on hydraulic pressure to maintain its hold, so the platforms will stay in position even if hydraulic pressure is lost. The pneumatic engagement and release system makes operation smooth and straightforward, allowing technicians to lock and unlock the lift with minimal effort. Safety is further enhanced by the inclusion of an overload valve that halts lifting 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. An automatic stop at the maximum lifting height protects the lift from over-extension, cutting power to the motor once the designated top position is reached. All operations are controlled through 24V push-button controls, which operate at a low voltage for enhanced operator safety. This is a particularly important feature in busy workshop environments where electrical safety is a priority. The platforms on the JB-35 measure 600mm in width and can be extended from 1520mm to 2060mm in length, accommodating vehicles with different wheelbases from compact cars to larger SUVs and light commercial vehicles.

Product highlights

Four-Cylinder Electro-Hydraulic System

The four-cylinder electro-hydraulic system on the CAV JB-35 delivers exceptional lifting power and smooth operation. Unlike two-cylinder designs that can experience uneven pressure distribution, the four-cylinder configuration spreads the lifting force evenly across both platforms, ensuring consistent and reliable performance. This design also provides a degree of redundancy; if one cylinder experiences a minor issue, the remaining three can still support the load during a controlled descent. The 2.2kW motor drives the hydraulic pump efficiently, providing the power needed for heavy daily use while maintaining energy efficiency.

Super Low-Profile Design for Low Vehicles

The 110mm minimum height of the JB-35 is a standout feature that sets it apart from many other scissor lifts. Standard lifts often require additional ramps or adapters to accommodate low-clearance vehicles, which adds time and complexity to the service process. The JB-35 eliminates this hassle, allowing sports cars, modified vehicles, and other low-profile cars to drive on easily without any additional equipment. This feature expands the range of vehicles a workshop can accept and reduces the risk of damage to vehicle body kits and underbody components during the drive-on process.

Hydraulic Synchronization for Level Lifting

The hydraulic synchronization system on the JB-35 ensures that both platforms move in perfect harmony throughout the lifting and lowering cycle. This is a critical safety feature that prevents the platforms from becoming uneven, which could cause a vehicle to shift or become unstable. The synchronization system automatically adjusts for any minor variations in hydraulic flow, keeping the platforms level even under uneven load distribution. This engineering detail gives technicians confidence that the vehicle will remain stable and secure during every operation.

Air-Operated Safety Locks

The air-operated safety locks on the JB-35 provide secure mechanical engagement at multiple points throughout the lifting range. These locks are engaged and released pneumatically, which offers several advantages over manual or purely electrical systems. The pneumatic operation provides a positive, reliable locking action that holds the platforms securely at the selected height. The mechanical nature of the locks means they are not dependent on hydraulic pressure to maintain their hold, providing an additional layer of safety. The air release system makes lowering smooth and controlled, allowing technicians to manage the descent with precision.

Comprehensive Multi-Layer Safety Protection

CAV has equipped the JB-35 with multiple independent safety systems that work together to protect both the operator and the equipment. The overload valve protects the lift from load-related issues, halting lifting if the rated 3.5-ton 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. The automatic stop at maximum lifting height protects the lift from over-extension, which could otherwise damage the hydraulic cylinders or the scissor mechanism. These three systems address different failure scenarios, providing layered protection that enhances overall workshop safety.

24V Low-Voltage Control System

The JB-35 uses a 24V push-button control system for all lifting and lowering operations. This low-voltage design is a thoughtful safety consideration that 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 Platforms for Versatile Fit

The platforms on the JB-35 are designed with flexibility in mind. They extend from 1520mm to 2060mm, accommodating vehicles with different wheelbases, from compact hatchbacks to larger sedans and SUVs. The 600mm platform width provides stable support for a wide range of tire sizes. This adjustability makes the JB-35 a versatile lift that can handle a wide variety of vehicle types without the need for adapters or additional accessories.
