Engineered vrijdragende takel met heen en weer gaande takel

Product Name: Engineered Cantilever Reciprocating Hoist

Product Model: Gradin CRH Series

Load Capacity: 300 – 8000kg (Customization Available)

Gradin builds cantilever Vertical Reciprocating Conveyors (VRCs) for multi-level material transfer. The single-mast design is intended for installations where a standard 4-post lift will not fit. Every unit is engineered to order. We design and manufacture the guide rails, carriage, and drive system based strictly on your required load capacity, platform dimensions, and travel height.

  • Rapid Response: Expert engineering consultation from day one.
  • Proven Process: Precision from initial concept to final client approval.
  • Certified Quality: ISO/CE compliant with industry-specific safety standards.
  • Direct Value: Transparent, factory-direct pricing for bespoke solutions.
  • Lifetime Support: Technical assistance for the product’s entire operational lifespan.

Detail

Product Features

  • Compact Single-Mast Structure: The cantilever design eliminates the need for a fully enclosed structural shaft. It mounts directly to a load-bearing wall or steel framework, making it suitable for narrow aisles or space-restricted plant areas.

  • Configurable Material Flow: The open-platform structure allows loading and unloading from multiple sides. The hoist is configurable for Z-type (opposite sides), C-type (same side), or L-type (90-degree) infeed and outfeed layouts.

  • VFD-Controlled Operation: Powered by a top-mounted gear motor integrated with a Variable Frequency Drive (VFD). This setup provides controlled acceleration and deceleration, preventing cargo shifting during vertical transit.

  • Gradin Standard Safety Systems: All manufactured units include mechanical anti-fall blocks, slack-chain sensors, overload limiters, and heavy-duty steel mesh enclosures with floor-interlocked access doors to meet international industrial safety standards.

Application scenarios & Vedio

1. Automated Production Line Transfer

Suitable for up-and-down reciprocating transportation of semi-finished products, tooling fixtures, and assembly parts between production floors. The cantilever outreach design realizes offset feeding and docking with production equipment, effectively connecting upper and lower process stations and forming a fully automated closed-loop logistics line.

2. Mezzanine & Multi-Floor Workshop Logistics

Ideal for material handling between factory mezzanines and multi-layer workshops. It makes full use of vertical space without occupying central passage space, solving the problem of vertical transportation in compact layout workshops and improving workshop space utilization.

3. Machinery & Heavy Industry Manufacturing

Used for reciprocating lifting and transferring of mechanical parts, casting components, and packaging materials. The heavy-duty structure adapts to long-term frequent start-stop operation, ensuring stable and consistent material supply for continuous production.

4. Electronic & Intelligent Factory Workshop

Applicable for handling finished products, packaging boxes, and auxiliary materials in precision manufacturing workshops. Smooth operation, low vibration, and high positioning accuracy ensure no damage or displacement of precision materials during vertical reciprocating delivery.

5. Warehouse & Storage Logistics

Perfect for vertical docking between warehouse floors, shelf access, and inbound and outbound reciprocating conveying. It matches automated conveying lines and AGV docking, realizing unmanned and efficient warehouse material transfer.

6. Special Narrow-space Working Conditions

Exclusive cantilever side-output design adapts to narrow installation spaces, wall-mounted layouts, and special station offset docking scenarios where conventional vertical hoists cannot be installed. It provides flexible and customized vertical logistics solutions for special industrial sites.

Gradin Customized Solutions

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.
