A high-throughput continuous vertical conveyor (CVC) engineered for extreme sorting frequencies. 100% custom-built, it utilizes synchronized mechanical fork-arms to interface flawlessly with grid conveyors, achieving an ultra-high throughput of up to 3000 pieces per hour without intermittent indexing delays or payload collisions.
Payload Geometry: Fork spacing, comb matrices, and carrier pitch are strictly calculated for your unique cartons or totes to eliminate jam-ups at peak velocity.
Synchronous Actuation: Servo-driven logic and closed-loop VFDs ensure absolute timing precision during rapid horizontal-to-vertical transfer.
Kinetic Integrity: FEA-validated drive chains and hardened steel fork-arms engineered to withstand continuous, high-cycle mechanical fatigue without elastic stretch.

Operating a Gradin 3000P/H Fork-Arm CVC at extreme velocities introduces immense harmonic stress. Unlike generic vertical conveyors that suffer from structural sway at high frequencies, our systems utilize advanced Finite Element Analysis (FEA) to optimize the mast “spine.” This engineering-first approach neutralizes resonant energy during rapid carrier indexing. By utilizing high-yield box-section alloy steel, we ensure the structure maintains absolute verticality even under 100% continuous duty cycles. Every fork-arm is individually modeled to neutralize torsional stress, ensuring that cargo remains perfectly horizontal during 2.0 m/s+ vertical transitions. This structural stiffness is critical for preserving the fatigue life of the system over decades of 24/7 operation.
Managing 3,000 units per hour requires a sophisticated digital pulse. The Gradin 3000P/H Fork-Arm CVC bypasses the mechanical shocks of traditional lifts via a Closed-Loop Servo Architecture integrated natively into our drive logic. Utilizing the Siemens S7-1500 PLC suite, the system achieves sub-millimeter deck alignment (±1mm) at every floor transition. This precision is essential for high-speed automated sortation hubs where pallet-jack or robotic handshakes demand zero-bump thresholds. Furthermore, our Active Buffer Logic allows the carrier loop to dynamically adjust velocity. If a downstream bottleneck is detected by the WMS, the CVC shifts into an intelligent buffering mode, storing units vertically to prevent an upstream line stoppage.
The Gradin 3000P/H Fork-Arm CVC functions as a transparent node within your facility’s digital nervous system. It is designed for seamless integration with modern AS/RS (Automated Storage and Retrieval Systems). Through Profinet, EtherCAT, or 5G connectivity, the system facilitates a real-time data handshake, reporting carrier occupancy, torque profiles, and unit coordinates directly to your MES. Our bespoke tooling DNA means the fork-arms are engineered specifically for your tote or pallet footprint, maximizing stability during aggressive vertical pulses. To ensure maximum uptime, integrated vibration sensors and motor torque profilers track the “health signature” of every carrier. This Predictive Maintenance Monitoring identifies component wear before it results in unplanned downtime, transforming maintenance from a reactive task to a scheduled strategy.
In the fast-paced world of e-commerce, moving 3,000+ totes per hour vertically between automated mezzanine levels is a primary operational hurdle. The Gradin 3000P/H Fork-Arm CVC eliminates this bottleneck with lubrication-free drive belts and sub-second handshakes with sortation networks. By removing the need for traditional chains, we eliminate chain-stretch and the resulting maintenance downtime, ensuring a continuous vertical items-per-minute (IPM) flow that standard reciprocating lifts cannot match.
Frozen goods distribution requires non-stop vertical movement in environments where standard lubricants freeze and metal becomes brittle. The bespoke Gradin 3000P/H Fork-Arm CVC is engineered with thermal-rated mechanical alloys and IP65-rated control enclosures. Our oil-free drive maintains 24/7 continuous flow without the leakage or freezing risks inherent in hydraulic or standard chain systems, preserving the thermal integrity of the facility while moving hundreds of units per hour.
Vertical transit between cleanroom floors requires a system that generates zero particulate matter and zero harmonic resonance. The custom Gradin 3000P/H Fork-Arm CVC utilizes high-tension polyurethane belts and stainless-steel cladding to maintain ISO Class environmental sterility. The vibration-dampened architecture ensures silent operation (< 60 dB), making it ideal for ergonomic workplaces and high-precision assembly links where mechanical noise must be minimized.
Redundant Architecture as the Absolute Priority
Safety in high-flux, multi-carrier vertical logistics—especially in facilities where humans interface with automated open shafts—is the core of our engineering mandate. The Gradin 3000P/H Fork-Arm CVC exceeds international regulatory standards through a multi-layered redundancy loop:
Active SIL 3 Risk Mitigation: We integrate ultra-fast jam-detection sensors and secondary mechanical lockouts to prevent carrier collisions and structural impact in the event of an obstruction.
Perimeter Safety Interlocks: Every system is designed with full-height shaft enclosures and high-speed power doors, electronically interlocked with the ASME B20.1 safety PLC logic to ensure zero operator access during high-velocity cycles.
Fail-Safe Mechanical Braking: Redundant electromagnetic braking systems provide a 200% holding torque safety margin. These engage instantly during an E-stop or power loss, securing the entire carrier loop and protecting high-value cargo from vertical drift.
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.
