Engenharia de uma plataforma de elevação de tesoura personalizada em forma de U para testes de energia de alta precisão

Visão geral do cliente

In a recent strategic project for a prominent Energy & Nuclear research facility in China, our engineering team developed a highly specialized U-Shaped Scissor Lift Platform. Designed for the “112 Compression Field Test Center,” this equipment provides a vertical transportation solution for personnel and precision components around a central test turntable. With an 11-meter stroke and integration into a constrained U-shaped pit, this project exemplifies the intersection of structural stability and advanced industrial safety protocols.

Desafio e solução

Desafios do cliente

The project site presented a set of rigorous engineering limitations that made standard lifting solutions inapplicable:

  • Complex Pit Geometry: The platform had to be installed in a U-shaped pit measuring 6980mm in length and 5740mm in width. A 100mm safety clearance from the pit walls was mandatory throughout the entire 11,000mm vertical journey.

  • High-Altitude Stability Requirements: Operating at an 11-meter elevation, the platform required a natural sway of 

     0.5% and a tilt differential of 

     50mm to ensure the safety of personnel performing delicate testing operations.

  • Zero-Wireless Mandate (EMI Compliance): Due to the sensitivity of the compression field testing equipment, the facility prohibited all wireless communication. Every control signal had to be transmitted via physical, shielded cabling.

Solução personalizada GRADIN

To address these challenges, we engineered a bespoke U-Shaped Scissor Lift Platform with an integrated telescopic deck system and a hardwired PLC logic controller.

1. Structural Logic and “U” Architecture

The chassis was constructed from high-tensile structural steel, precision-aligned to the U-shaped pit. The lift utilizes a heavy-duty scissor mechanism optimized for long-stroke stability, ensuring the platform remains rigid even when subjected to horizontal lateral forces at maximum height.

2. Independent Telescopic Zones (A, B, and C)

To provide flexible access to the test subject, the platform features three independently controlled telescopic decks:

  • Zone A: A 3000mm wide extension reaching up to 1500mm, with a dedicated 350kg load capacity.

  • Zones B & C: Optimized for lateral proximity with 700mm extensions.

  • Safety Sensing: Zone A includes non-contact photoelectric limit switches that automatically lock movement when within 50mm of any structural obstacle.

3. EMI-Secure Wired Control System

The electrical architecture is strictly hardwired, featuring a PLC system that manages complex interlocks. The system prevents any vertical movement if telescopic decks are extended or if the 1100mm safety railings are not mechanically secured.

Safety & Compliance Features

Safety is paramount in nuclear and energy testing environments. Our U-Shaped Scissor Lift Platform integrates:

  1. Anti-Fall Protection: Redundant mechanical safety cams to prevent uncontrolled descent.

  2. Emergency Self-Rescue: A manual hydraulic lowering valve allowing operators to descend safely during a total power failure.

  3. Interlock Logic: Preventing lift operations unless the telescopic sections are fully retracted and the manual gates (East, West, and South) are locked.

  4. Environmental Durability: IP55-rated electrical components with waterproof, vibration-proof, and dust-proof enclosures.

Outcome and Reliability

The platform was delivered with a complete technical dossier, including BOMs for all components and a 10-year service life guarantee (based on 10 cycles/day). Since installation, the system has provided the client with a stable, interference-free work environment, significantly enhancing the efficiency of their compression field testing operations in China.
