Synchronized Dual-Cylinder & 4-Post Stability: Engineered with a 2-cylinder, 4-rail (125H) architecture to ensure balanced force distribution and exceptional platform stability during high-tonnage lifting.
Pitless Installation Versatility: Specifically designed for facilities where floor excavation is impossible; the system mounts directly to the existing concrete floor, utilizing a 10-degree entry ramp for forklift access.
Integrated Roller Door Linkage: Features an automated control logic that synchronizes the lift’s operation with the PVC rolling doors, ensuring the lift remains stationary until all safety barriers are secured.
Forklift-Friendly Entry Ramp: Equipped with a custom-engineered 680mm long ramp with a gentle 10-degree incline, facilitating smooth transitions for manual pallet jacks and heavy-duty forklifts.
High-Strength 125H Guide Rail System: Utilizes industrial-grade 125H structural steel rails to eliminate platform sway and ensure precise vertical alignment over the 3,750mm travel range.
Advanced Wireless & PLC Control: Incorporates a localized control cabinet combined with wireless remote capabilities, allowing for flexible operation and real-time status monitoring from various floor levels.
Multi-Layer Safety Guarding: Features 1.2m high platform guardrails and a full-height diamond-mesh outer enclosure (20x40mm) to prevent unauthorized access and protect personnel during high-capacity cycles.
Industrial Mezzanine Logistics: Providing an efficient vertical link to elevated storage areas in warehouses where floor excavation is restricted, allowing for the safe transfer of 3,000kg palletized loads via forklift.
Heavy Machinery Manufacturing: Facilitating the movement of large sub-assemblies and raw materials between production levels, ensuring a continuous supply chain within the assembly plant.
Automotive Parts Distribution: Ideal for multi-story parts centers requiring a robust, pitless lifting solution to move heavy engines, transmissions, and palletized inventory using manual or electric pallet jacks.
Retrofit Facility Upgrades: Designed for existing buildings with thick concrete slabs where traditional pit-mounted lifts are not feasible, offering a bolt-on solution for vertical material handling.
Integrated Production Lines: Bridging the height gap between incoming material receiving and elevated processing stations, with automated door linkage ensuring synchronized material flow.
Retail and Wholesale Backrooms: Managing the vertical transport of bulky inventory from ground-level docks to mezzanine racking, utilizing the integrated ramp for seamless trolley and pallet jack access.
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.
