Product Features

Pure Mechanical Screw Drive, Zero Oil Pollution
Different from traditional hydraulic lifts, this four-post lift adopts engine-driven screw-nut mechanical transmission, completely eliminating hydraulic oil leakage, oil pipe aging and oil contamination problems. It maintains clean and tidy workshop environment, meeting high-standard maintenance and production environmental requirements.
Four-Column Synchronous Lifting, Ultra-Stable Operation
Equipped with four high-precision lifting screw columns and synchronous linkage system, the platform keeps horizontal and balanced during the whole lifting process. It effectively solves tilt and jitter issues caused by uneven cargo load, ensuring stable support for vehicle maintenance and engine disassembly operations.
Full Mechanical Self-Locking, Higher Safety
The professional screw self-locking structure enables stable height locking at any position. Even in case of power failure or equipment failure, the platform will not slide or fall, providing continuous safety guarantee for under-platform manual operation, far safer than ordinary hydraulic locking modes.
Heavy-Duty Reinforced Structure, Durable & Low Maintenance
The whole machine adopts thickened steel frame and wear-resistant alloy screw rod, with strong compression resistance and anti-fatigue performance. It supports long-term high-frequency heavy-load operation, with fewer wearing parts and no regular oil replacement required, greatly reducing later maintenance costs and downtime.
Simple Operation & High Efficiency
Integrated electric control system realizes one-key lifting and lowering with sensitive response and stable running speed. Operators can freely adjust working height according to maintenance needs, effectively improving the efficiency of vehicle inspection, engine disassembly and equipment overhaul.
Flexible Customization & Wide Adaptability
Platform size, lifting stroke and load grade can be customized according to on-site working conditions. Optional mobile walking device enables flexible position switching, adapting to fixed stations and multi-scene mobile maintenance operations.

Application scenarios & Vedio

1. Automobile Repair & Maintenance Workshop
Widely used for daily maintenance, chassis inspection, tire replacement and bottom overhaul of cars, SUVs and light trucks. Stable lifting and self-locking safety ensure reliable support for long-time under-vehicle operation.
2. Engine Disassembly & Overhaul Station
Specially applicable for disassembly, maintenance and assembly of automobile engines, gearboxes and heavy mechanical core components. The stable and non-slip platform provides safe and convenient operating conditions for precision component overhaul.
3. Heavy Vehicle Maintenance Center
Suitable for overhaul and maintenance of medium and heavy trucks, buses and engineering vehicles. Super heavy-load capacity and anti-tilt structure meet the lifting demands of large and heavy vehicles.
4. Industrial Mechanical Equipment Overhaul
Used for height-adjustable lifting support during disassembly and maintenance of large industrial equipment, mechanical parts and production line devices, improving the convenience of high-altitude overhaul work.
5. Professional Inspection & Testing Institution
Applied for vehicle performance testing, chassis parameter calibration and equipment safety detection. The high-precision synchronous lifting ensures horizontal platform level, guaranteeing accurate detection data.

Gradin Customized Solutions

For this heavy-duty series, we can engineer load capacities up to [300] tons, with platform dimensions and lifting heights customized to your operational envelope. Requirements exceeding our standard engineering matrix will undergo a Finite Element Analysis (FEA) by our engineering team to ensure structural viability before proposing a solution.

To initiate the engineering proposal, please provide the following baseline data:

  • Rated Load Capacity

  • Maximum Lifting Height & Closed Height

  • Platform Dimensions (L x W)

  • Duty Cycle (e.g., operational cycles per hour/day)

  • Environmental Conditions (e.g., indoor/outdoor, washdown, explosion-proof)

  • Pit depth or overhead clearance constraints

Yes. The control systems can be equipped with standard communication protocols (e.g., Profinet, Modbus, Ethernet/IP) utilizing [Siemens / Allen-Bradley / Omron] PLCs. This ensures seamless I/O signal synchronization with upstream/downstream conveyors, AGV/AMR units, and your central control room.

Every custom unit undergoes a mandatory Factory Acceptance Test (FAT) prior to dispatch. This includes continuous operational testing at 100% rated load, static overload testing at [120% / 125%] capacity, and the physical triggering of all mechanical anti-fall and hydraulic safety interlocks. FAT documentation and video proof are included in your engineering package.

Upon final approval of the General Arrangement (GA) drawings, the manufacturing lead time is typically 4 to 8 weeks. Oversized structural components are engineered with a modular design to fit into standard shipping containers (20FT/40HQ). On-site assembly utilizes pre-engineered bolted flange connections and heavy-duty aviation plugs, strictly eliminating the need for field welding.

We provide a standard [12/24]-month warranty covering the structural frame and primary hydraulic/electrical components. To minimize operational downtime, a comprehensive set of standard consumables (e.g., cylinder seal kits, travel switches, relays) is shipped alongside your equipment. During the warranty period, replacement parts for non-human-induced failures are dispatched via priority air freight (DHL/FedEx) within 48 hours.

Beyond the warranty, we guarantee lifetime engineering support. Your custom equipment's CAD drawings, electrical schematics, and BOM (Bill of Materials) are permanently archived in our system. This ensures you receive uninterrupted remote troubleshooting, maintenance guidance, and exact spare parts matching for the entire lifecycle of the equipment.
