1. Product Overview
The 4-ton gantry lift (gantry-type double-column lift) is the standard chassis maintenance equipment for auto repair stores and 4S stores. It has a rated load-bearing capacity of 4000kg and adopts double columns + top beam. The one-piece gantry structure and dual-cylinder hydraulic drive are specially designed to provide lifting operations for family cars, SUVs, small new energy vehicles, and light commercial vehicles. It is suitable for all types of maintenance projects such as oil change, chassis inspection, four-wheel alignment, tire replacement, and suspension repair.
2. Core basic parameters
1. Rated lifting load: 4000kg (4 tons)
2. Lifting height: 1780–1970mm; minimum lifting height 110–130mm, suitable for low-lying luxury models
3. Lifting speed: rising ≤50 seconds, falling 20-40 seconds
4. Power configuration: 2.2KW hydraulic motor, supporting 380V three-phase/220V single-phase dual voltage
5. Body size
- The inner width of the column is about 2700-3000mm, and the vehicle width is 2300-2700mm
- The height of the whole machine is 3400–3840mm, and the clear height of the workshop must be ≥ 3.8 meters
6. Support arm structure: three-section telescopic symmetrical/asymmetric rocker arm, which can rotate 180° and is suitable for vehicles with different wheelbases
7. Standard accessories: elevated support pad, mechanical safety lock, emergency stop switch, anti-collision rubber pad, synchronized steel cable, operation manual
3. Structure and hardware configuration
1. Integrated gantry frame
Thickened whole-plate bent columns + top through-beam, strong overall rigidity, no shaking when lifting; built-in hidden wiring of oil pipes and cables, neat appearance, avoiding pipeline damage from collision.
2. Dual-cylinder direct-drive hydraulic system
Double-side synchronized hydraulic cylinders, lifting smoothly and without interruption; built-in overload safety valve, automatic pressure relief when overloaded, eliminating the risk of cylinder explosion; transparent oil storage barrel, easy to visually check the hydraulic oil level.
3. Forced synchronous balancing system
Double steel wire ropes synchronously link the sliding platforms on both sides. The lifting and lowering of the columns are completely synchronized during the lifting process to prevent the vehicle from tilting or rolling over on one side.
4. Multiple safety protection mechanisms
- Mechanical fully automatic safety lock: automatically locks when lifted to the position, manually unlocks before lowering, and will not crash even if power is cut off or oil leaks;
- Mechanical top limiter: prevents the vehicle roof from being squeezed by excessive lifting;
- Emergency stop power button at the bottom of the column, one-click shutdown in emergency conditions;
- The support arm has a widened serrated locking block, which is firmly locked after bearing the load, preventing the support arm from slipping;
- The door anti-collision rubber pads on both sides of the column prevent the lift from scratching the car body paint.
5. Adjustable lifting component
Three-section telescopic rocker arm, the front and rear length can be adjusted freely; the spiral heightening support pad is suitable for different types of chassis, and the new energy vehicle chassis guard can also be stably supported.
4. Core functional advantages
1. The working space is wide and suitable for four-wheel positioning
There is no crossbeam on the top to block the chassis area. After lifting, there are no obstacles under the chassis. With the corner plate and locator, a complete set of 3D four-wheel positioning measurements can be directly completed. It is the preferred model for positioning stations.
2. Compatible with all categories of household models
The 4-ton load-bearing capacity covers fuel cars, hybrid/pure electric new energy SUVs, and MPV light commercial vehicles; the minimum low-level lift is 110mm, and supercars and low-riding models can be put on the shelves normally.
3. Durable and easy to maintain
Patented wear-resistant slider structure makes it easy to replace accessories; the hydraulic system seals are standardized and subsequent maintenance costs are low; the whole machine has passed 115% overload and 150% static load safety tests, and will not deform after long-term high-frequency use.
4. Simple and labor-saving operation
It is divided into two styles: unilateral/bilateral manual unlocking. A single person can complete the lifting operation; the hydraulic lifting noise is ≤75dB, and the store operation is quiet and does not disturb people.
5. Easy installation
The ground-mounted design eliminates the need to dig deep foundations and can be fixed on a flat concrete floor; the whole machine is shipped separately and spliced and assembled on-site, with a short debugging cycle and can be quickly put into operation.
5. Applicable scenarios
- Professional comprehensive auto repair stores, automobile 4S service centers
- Quick repair and maintenance shops, special tire positioning stations
- New energy vehicle maintenance workshops, modification stores
- Specialized station for second-hand car inspection and chassis failure repair
6. Adaptable supporting equipment
It can be used simultaneously with a 3D four-wheel aligner, dynamic balancing machine, tire stripping machine and oil recovery machine to build a complete car maintenance station.
7. Key points for safe operation
1. It is strictly prohibited to lift large trucks with overload of 4 tons;
2. After the vehicle is put on the rack, the support arm must be adjusted to the designated support point of the chassis, and it is prohibited to lift plastic guards and oil pans;
3. Lift the vehicle 10cm off the ground and then shake the vehicle gently to confirm that the lock block is tight and the body is stable before raising the vehicle;
4. The equipment needs to be regularly checked for hydraulic oil, wire ropes, and safety locks. If there is any abnormality, it must be shut down immediately for maintenance.
