In-Ground Hydraulic Scissor Alignment Lifts

In-Ground hydraulic scissor alignment lifts is a vehicle maintenance lifting solution specifically developed for high-end quick-service shops and tire service centers. Its pit-embedded installation design ensures the equipment sits completely flush with the ground when retracted, eliminating floor-level obstructions. This makes it an excellent choice for creating a fully flat workshop with a scissor-type vehicle lift.

With a main platform rated load of 4000kg, this heavy-duty in-ground sub-scissor lift equipment sets an industry-leading benchmark, capable of stably supporting large SUVs, full-size MPVs, light passenger vans, and certain medium-duty commercial vehicles.

A key advantage of this equipment is the integrated secondary lift jack system. Featuring a secondary lift height of 450mm, this in-ground large-scissor lift with secondary lift capability can raise an additional 450mm after the main platform reaches 1850mm, achieving a total working height of 2300mm. This provides ample standing room for tasks such as four-wheel alignment sensor installation, suspension system repair, and tire replacement. Structurally, the equipment boasts an ultra-long platform length of 4500mm for this in-ground large-scissor lift, paired with a single platform width of 625mm to form a spacious and stable vehicle support base. The power system utilizes a 3kW motor, operating at an air pressure of 0.4MPa and an oil pressure of 20MPa, ensuring a smooth and powerful lifting process.

Traditional floor-mounted large-scissor lifts have platforms that sit above the ground after installation, creating physical obstacles that impede vehicle traffic and workshop workflow planning, while also requiring additional space for the equipment itself. This equipment adopts a pit-embedded in-ground sub-scissor lift design, leaving the platform flush with the ground after installation, allowing vehicles to pass unobstructed when not raised. Real-world data shows this solution improves effective workshop floor space utilization by over 25%, making it especially suitable for space-constrained four-wheel alignment bays and quick-service chain stores.

The curb weight of large commercial vehicles, full-size SUVs, and luxury MPVs often exceeds 3000kg. Traditional 3500kg-class lifts approach their load limit when handling such vehicles, posing potential safety risks with long-term use. This equipment offers a rated load capacity of 4000kg for heavy-duty in-ground sub-scissor lift equipment, a 14% increase over conventional industry products. Validated by finite element analysis, under a full 4000kg load condition, structural deformation is less than 0.6mm, ensuring a service life exceeding 10 years in high-frequency, heavy-load scenarios with over 20 cycles per day.

Four-wheel alignment and undercarriage repairs demand significant lift height. Insufficient height forces technicians to bend or squat for extended periods, severely impacting operational precision and comfort. After the main platform rises to the 1850mm height of this in-ground large-scissor lift, the built-in secondary jack can lift an additional 450mm, reaching a total working height of 2300mm. This allows a 1.85-meter-tall technician to walk upright completely under the vehicle, improving operational comfort by 60%, reducing four-wheel alignment sensor installation time by 30%, and significantly enhancing adjustment accuracy.

Traditional four-wheel alignment lift platforms are often under 4200mm in length. When handling large MPVs with wheelbases exceeding 3400mm, or light passenger vans like the Mercedes-Benz Sprinter, the tire support points often fall near or beyond the platform edges, creating safety risks. This equipment features a 4500mm extra-long platform in-ground large-scissor lift, which, combined with a 625mm single platform width, can cover various vehicle models with wheelbases up to 3900mm. This ensures tires are fully supported within the platform area while providing ample working space for technicians on both sides under the vehicle.

Traditional mechanical locks require manual operation for each point, posing fall risks due to oversight or operational error. This equipment features a pneumatic release in-ground sub-scissor lift design, utilizing a central pneumatic control system for synchronized opening and closing of all safety locks, reducing the single descent operation time to under 5 seconds. The equipment can only execute the descent command when all safety locks are fully engaged and in position, providing "zero misoperation" safety protection physically and increasing bay turnover efficiency by 25%.
