A multi-stage scissor lift engineered for high-capacity, high-stroke applications where platform stability and positioning accuracy are non-negotiable. Driven by a rigid chain actuator system rather than hydraulics, it delivers millimeter-level positioning accuracy and holds position mechanically without creep, pressure loss, or fluid maintenance. Every unit is built to order against your specific footprint, payload, and integration requirements.

Zero-Drift Mechanical Actuation An electric motor, gearbox, and rigid chain mechanism drives the platform to the target height and locks it in place mechanically. No hydraulic oil, no pressure loss, no platform drift during extended high-elevation holds — regardless of load duration or ambient temperature.
High-Rigidity Scissor Structure Fabricated from Q345B or Q235B heavy-duty manganese steel rectangular tube sections. Self-lubricating bearings at all pivot points minimize deflection and lateral sway under full load at maximum stroke, maintaining structural geometry throughout the service life of the unit.
Mobility and On-Site Leveling Heavy-duty polyurethane swivel casters allow repositioning across the shop floor without lifting equipment. Manual screw jack outriggers convert the unit to a fixed, level workstation on uneven surfaces in under two minutes — no tools required beyond the standard jack handle.
Engineered-to-Order Configuration Capacity, stroke, platform dimensions, and integration requirements are specified per project. Available configurations include explosion-proof motors for HazLoc environments, cleanroom-grade surface finishes, roller conveyor tops for inline transfer, and PLC integration for AGV handoff protocols.
Automotive and Heavy Assembly EV battery pack mating, chassis sub-assembly positioning, and aerospace component alignment where height repeatability directly affects assembly quality.
Cleanroom and Controlled Environments Pharmaceutical, food processing, and semiconductor facilities requiring oil-free, zero-leak vertical positioning. No hydraulic fluid means no contamination risk to the production environment.
Die and Mold Handling Precise transfer of injection molds and stamping dies to press height without position creep. Mechanical locking holds the platform at the exact transfer elevation for as long as the operation requires.
Automated Production Lines Fixed-height or multi-position transfer stations integrated with conveyor systems and AGV networks. PLC handshake protocols and precision floor-level sensors available as standard engineering options.
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.
