The Heavy-Duty Freight Scissor Lift by Gradin Lifts is engineered to streamline high-volume, multi-level vertical cargo dispatching up to 10,000 kg.
Dual-Deck Space Optimization: Configured with a 3300 x 2000 mm dual-deck assembly, allowing users to load and lift two independent cargo lines simultaneously.
High-Volume Electro-Hydraulics: Driven by dual Φ 160 mm bore cylinders and an 11 kW motor, enabling a stable 3100 mm lifting stroke under full payload.
Zero-Obstruction Pit Design: Integrates a low-profile 635 mm closed height that sits flush with the warehouse floor when fully collapsed, allowing pallet jacks to drive straight on.

To support concentrated rolling loads up to 10 Tons (10,000 kg), the main scissor mechanism is fabricated from heavy-walled Q235 carbon steel rectangular tubes measuring 250 x 150 x 8 mm. This massive structural core is paired with a base frame built from 20# structural channel steel. The lower deck frame utilizes matching 20# channel steel, while the secondary upper deck is constructed from 160 x 80 x 4 mm rectangular tubing to optimize weight-to-strength ratios, eliminating localized steel deflection when loaded by heavy industrial forklifts.
The lifting force is generated by dual heavy-duty cylinders featuring a Φ 140 mm bore and Φ 100 mm piston rods, direct-coupled to a central 7.5 kW hydraulic power pack. Oil flow is regulated through integrated manifold blocks containing velocity-fuses and flow-control valves to guarantee synchronous ascent under unbalanced payloads. The cylinder assemblies are sealed with imported NOK high-pressure seal rings, preventing dynamic fluid bypass and maintaining exact platform elevation over long holding periods during dispatch.
This freight lift is designed for a deep-pit installation (pit dimensions: 5543 x 2635 x 3454.5 mm) with a collapsed self-height of only 635 mm. This low-profile geometry allows the top deck of the dual-platform system to remain completely flush with the surrounding concrete warehouse floor when fully lowered. Pallet jacks, stackers, and automated guided vehicles (AGVs) can transition onto the platform at a 0-degree angle without requiring any transitional metal ramps, drastically accelerating cycle times.
The physical architecture of the lift includes a secondary, vertical post-supported upper deck positioned directly above the primary scissor platform. This dual-level layout is engineered for synchronized warehouse mezzanine loading. While the lower platform transfers heavy machinery or palletized raw materials down to subterranean storage pits, the upper platform can simultaneously accept and transport finished goods up to mezzanine dispatch stations, effectively doubling the vertical throughout of the facility.
Your Problem: Transporting 10-ton palletized cargo between the ground floor and second-level storage mezzanines using dynamic forklift ramps is slow, consumes warehouse floor space, and risks forklift tipping.
Gradin Solution: This pit-mounted scissor platform provides high-speed vertical elevation. A forklift simply deposits a 10-ton batch on the flush-floor deck, and the operator raises it directly to the mezzanine level in under a minute, keeping forklifts on their respective levels and preserving valuable floor space.
Your Problem: Multi-level parking or deep subterranean warehouse basements require separate lift systems to handle inbound and outbound cargo, creating building cost bottlenecks.
Gradin Solution: The dual-deck platform layout allows two vehicles or heavy pallets to be loaded simultaneously. As the lower platform descends to retrieve materials from the basement, the top deck aligns with the main warehouse floor, allowing cargo to flow continuously.
Your Problem: Moving heavy stamping dies or manufacturing molds from central maintenance pits up to floor-level injection lines requires high-capacity cranes and poses severe crane-cable failure risks.
Gradin Solution: Our reinforced 4mm steel deck handles high concentrated point loads. High-capacity mold carts can be driven directly onto the flush platform, which lifts the tooling safely to press bed height for fast, crane-free changeovers.
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.
