Detail

Product Features

Unique Hollow U-Notch All-Round Operation Design
The exclusive middle U-shaped hollow structure allows large workpieces and equipment components to be embedded in the platform center. Workers can stand on the three-sided solid platform to perform surrounding assembly, welding, inspection and maintenance operations, completely solving the blind spot problem of traditional full-surface lifting platforms. The large customized platform supports multi-person synchronous cooperative work, greatly improving overall operating efficiency.
Ultra-Low Profile Ground Installation, No Civil Works
With an ultra-low folded height of only 90mm, the platform requires no foundation pit excavation, and can be directly fixed on flat concrete ground for rapid installation. It effectively saves workshop civil engineering costs and shortens equipment commissioning cycle, featuring flexible and convenient on-site layout.
Heavy-Duty Structure, Stable Personnel Load Operation
Adopting thickened manganese steel double scissor arm and reinforced overall frame structure, the platform has high rigidity and strong anti-deformation capability. It remains stable without jitter or tilt during full-load multi-person standing operation. Matched with overload protection and hydraulic anti-burst safety devices, it ensures zero-risk operation for personnel aerial work.
Precision Stepless Speed Regulation & Arbitrary Height Locking
Equipped with variable frequency speed regulation system, it supports fast lifting for height adjustment and low-speed creeping for precision assembly. The platform can be locked stably at any required height, adapting to diverse working requirements of rough assembly, fine debugging and precision installation.
Complete Safety Protection, Comply with Industrial Standards
Full-range safety configurations including perimeter anti-pinch safety edge, anti-fall hydraulic protection, mechanical limit device and full surround guardrail effectively avoid clamping, falling and collision accidents. The whole machine complies with EU CE and industrial aerial operation safety standards, ensuring long-term safe and high-intensity workshop operation.
High Customization Flexibility
Platform overall dimension, U-notch opening size, lifting stroke and load capacity can be customized according to workpiece specifications and workshop station layout. It supports customized dust-proof, explosion-proof and anti-corrosion configurations to adapt to special industrial production environments.

Application scenarios & Vedio

1. Automobile & New Energy Vehicle Assembly Workshop
Ideal for chassis assembly, engine peripheral installation and vehicle debugging operations. The U-shaped hollow notch accommodates vehicle frame sinking, enabling workers to conduct all-round bottom and surrounding assembly work, perfectly matching automobile assembly line operation needs.
2. Heavy Machinery & Large Equipment Overhaul
Suitable for maintenance and debugging of large motors, gearboxes, engineering machinery components and mechanical equipment. Large workpieces are placed in the U hollow area, allowing multi-angle inspection, disassembly and maintenance by operators to improve overhaul efficiency.
3. Industrial Equipment Production & Debugging Line
Used as an adjustable fixed-height working station for large mechanical equipment assembly, finished product testing and component fitting. It replaces traditional fixed platforms, flexibly adapting to different assembly heights and improving production line flexibility.
4. Ship & Engineering Component Processing
Customized large-size U-shaped lifting platform is applicable for processing, welding and assembly of oversized castings and ship accessories. Multi-person cooperative operation mode significantly improves the production efficiency of large component processing workshops.
5. Automated Workshop Daily Maintenance
Widely used for height-adjustable access operation of automated assembly lines, stereo racks and conveying equipment. It facilitates daily inspection, component replacement and equipment maintenance, reducing manual operation difficulty and improving workshop maintenance efficiency.

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.
