This Fork-Arm CVC (Continuous Vertical Conveyor) acts as an ultra-high-speed vertical bridge for the non-stop transfer of palletized goods or heavy containers across multiple facility levels. Built by Gradin as a custom engineered-to-order (ETO) solution, the system is specifically rated for high-intensity duty cycles, achieving a high-throughput capacity of 2,000 units per hour (2000 P/H). Unlike standard reciprocating lifts, the fork-arm mechanism allows for simultaneous loading and unloading during the continuous vertical loop, effectively eliminating the wait times associated with single-platform cycles. Engineered for 24/7 integration with high-density automated storage and retrieval systems (AS/RS), this Fork-Arm CVC ensures a synchronized, vibration-free flow of materials, significantly increasing the vertical logistical throughput in modern distribution centers and manufacturing plants.

High-Frequency Structural Integrity & FEA Validation
Operating at 2,000 pieces per hour creates massive dynamic stress. Every Gradin 2000P/H Fork-Arm CVC is engineered using Finite Element Analysis (FEA) to eliminate structural fatigue.
Vibration Control: Precision-welded masts designed for zero-deflection at maximum velocity.
High-Tensile Chains: We utilize pre-stretched alloy chains to prevent operational elongation.
Precision Guidance: Precision-ground rails ensure a perfectly smooth vertical material flow 24/7.
Intelligent Servo-Driven Synchronization Logic
The bottleneck of high-speed lifts is the timing between conveyors and fork arms. Our bespoke PLC timing logic ensures micro-second coordination.
Zero-Collision Flow: Servo-drive systems eliminate the risk of product damage at in-feed stations.
Real-Time Sync: Seamlessly integrates with your production line tempo via Profinet or EtherCAT.
Millimeter Accuracy: Every item is picked up and deposited with extreme precision, even at peak throughput.
Adaptive Fork Design and Interface Flexibility
Unlike standard lifts, our CVC adapts to your specific cargo center of gravity. We engineer bespoke fork geometries for your pallets or totes.
Protective Handling: Forks can be equipped with soft-touch materials to protect sensitive packaging.
Layout Optimization: Available in C, Z, or S-flow configurations to maximize your vertical floor space.
Modular Scalability: Easily adjustable to accommodate future changes in your product dimensions.
[E-commerce & Fulfillment] – High-Frequency Sortation
In high-volume hubs, vertical speed defines shipping capacity. The Gradin 2000P/H Fork-Arm CVC enables continuous flow between picking and packing floors.
Eliminate Waiting: Removes the “dwell time” associated with standard reciprocating lifts.
Acoustic Comfort: Customized with full sheet-metal enclosures for low-noise environments.
[Food & Beverage] – Multi-Level Automated Logistics
Designed for high-output bottling or processing plants moving finished goods to high-level palletizers.
Hygiene Standard: Available in stainless steel with wash-down grade components (IP66).
Data Transparency: Industry 4.0 connectivity provides real-time tracking for every crate or carton.
[Automotive & Manufacturing] – Just-in-Time (JIT) Delivery
Providing a stable vertical link for transporting heavy automotive totes or specialized parts containers.
Bi-Directional Flow: Move full parts containers up while returning empty bins down simultaneously.
Heavy-Duty Reliability: High-torque motors and redundant safety interlocks ensure zero downtime.
Redundant Safety & High-Speed Monitoring Architecture
Safety in high-speed automated environments is our most critical engineering priority.
Interference Detection: Laser-based sensors at all ports execute a controlled stop if an item is misaligned.
Fail-Safe Mechanicals: Equipped with anti-backrun gears and torque limiters for total chain protection.
Compliance: Meets and exceeds international regulatory standards for high-tonnage automated vertical flow.
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.
