Reciprocating Cyclic Lifting
Adopts professional reciprocating mechanical structure to realize continuous cyclic up-and-down conveying, effectively improving production line circulation efficiency and avoiding intermittent standby waste of traditional lifting equipment.
High-Frequency Stable Operation
Optimized transmission and bearing structure adapts to long-term high-frequency cyclic work, with stable operating rhythm, low vibration and low noise, meeting the continuous production needs of automated workshops.
Precision Positioning & Docking
Equipped with precise positioning and calibration components, it achieves accurate stop and docking of pallets and fixtures, ensuring consistent assembly and conveying accuracy of the production line.
Strong Compatibility & Customization
Supports customized load capacity, lifting stroke and platform size, compatible with various standard pallets, custom tooling fixtures and different specifications of workpieces, adapting to diverse production line layouts.
Complete Safety Protection
Built with anti-blocking, overload protection, emergency stop and limit protection devices to prevent equipment failure and workpiece damage during high-frequency reciprocating operation, ensuring production safety.
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.
