To resolve high-throughput sorting bottlenecks in automated warehouses, our engineering team developed this rugged reciprocating cantilever fork lift VRC. Sized specifically for 30kg parts bins, our design coordinates high-speed chain-driven vertical travel with field-level automation grids.
Deflection-Free Cantilever Prongs: Our heavy-duty dual-pronged steel forks withstand asymmetrical load moments during high-speed vertical cycles.
Direct-Drive Chain Mechanics: We utilize premium alloy leaf chains driven by a 2.2kW gearmotor to eliminate belt slippage.
Profinet Cyclic Handshake: Our control layout utilizes a native communication bus to sync conveyor transitions without cycle lag.

To prevent column twisting and guide-track binding under continuous duty, we weld the vertical mast using custom cold-rolled steel channels instead of lightweight hollow tubes.
Our drive system relies on heavy-duty double-strand leaf chains, coupled with a 2.2kW Chengbang gearmotor, delivering positive-displacement vertical hoisting with zero backlash.
We apply a high-solid RAL 6002 polyurethane finish over grit-blasted steel to resist the constant sliding abrasion of plastic parts bins over years of operation.
We install self-lubricating sintered bronze bushings at all critical chain-attachment pivot pins to reduce the need for daily greasing.
Our split-column design incorporates dedicated inspection ports, allowing our field technicians to easily check chain tensioners and adjust proximity limit switches.
Our engineering division supports every custom vertical lift with a comprehensive 12-month parts warranty backed by active online PLC diagnostics.
We pre-configure the control panel with an integrated Profinet communication card to enable native cyclic I/O mapping with your master warehouse PLC.
Our system incorporates twin motorized roller conveyors at the loading stations to automate pallet-free box transfers with zero manual sorting errors.
We pre-wire all on-board field sensors to a centralized junction box utilizing quick-disconnect industrial connectors to simplify on-site installation.
We mount redundant photoelectric sensors at the transfer zones to immediately drop motor power if a tote bin exceeds the maximum safe envelope.
Our physical safety package features robust steel wire caging with solenoid-interlocked doors, preventing active access to the carriage zone during cycles.
Our direct-acting mechanical slack-chain switches stop the drive instantly if any chain tension loss or cargo jam occurs.
Industry Standards & Compliance:
Designed to fully satisfy the strict ASME B20.1 safety standards for conveyors and vertical lifts.
Configured in full accordance with OSHA machinery safeguarding guidelines to eliminate mechanical entrapment hazards.
CE certified under the European Machinery Directive 2006/42/EC for our automated vertical reciprocating conveyors.
High-travel vertical material transfer between factory floor and elevated mezzanine warehouse platforms.
Workpiece height positioning in automotive assembly and mechanical component maintenance cells.
Interfloor logistics delivery of raw materials and finished packaging boxes in printing plants.
Transitioning heavy roll-cages and manual pallet jacks between different height warehouse loading decks.
Safe cargo lifting inside compact warehouse elevators where vertical guide space is restricted.
Vertical feeding of materials into processing machinery in chemical packaging facilities.
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.
