Challenge

Demanding Load Requirements: Transporting heavy component assemblies along with the forklift itself, necessitating exceptional dynamic and static load-bearing capacity.
Stringent Safety Standards: The “zero-tolerance” safety standards of aerospace manufacturing required multiple, redundant safety mechanisms to prevent any potential falling or impact risks.
Spatial & Process Integration: The equipment needed to integrate perfectly with the existing factory layout (limited pit depth) and material flow, enabling through-floor access on the first level and matching multiple stop points.
Reliability & Durability: As a critical node in the production process, the equipment demanded extremely high operational reliability and long-term durability to maintain continuous production flow.

Solution

1. Core Design & Performance Specifications

Model: Custom SJD2-6 Double-Speed Lifting Platform
Load Capacity: Rated load of 2000 kg, with a reinforced platform structure capable of withstanding the static pressure and dynamic movement of a 6-ton forklift.
Dimensions: Platform size of 4000mm x 2500mm, providing ample space for large landing gear components and forklift operation.
Operational Efficiency: The double-speed mechanism doubles the platform’s lifting speed for a given cylinder stroke, significantly reducing wait times for component transfer.

2. Core Safety & Reliability Design

Reinforced Structure: Main frame built with 125H national standard heavy-duty guide rails and thickened structural steel (e.g., J160x80x4) to ensure overall rigidity.
Multi-Layered Safety Protection:
- Mechanical Landing Lock: Features physical locking push-rods at each landing level in addition to the hydraulic system lock, providing fail-safe securing.
- Intelligent Overload Protection: Integrated audible/visual alarm system that automatically cuts power upon overload.
- Operation Warning: Activates warning lights and sounds during ascent/descent to alert personnel.
Environmental Resilience: The platform boasts an IP55 protection rating against dust and water jets. The platform surface received specialized anti-rust coating for longevity.

3. Customized Process Integration

Through-Type Logistics Design: Enables straight-line, one-way forklift passage along the 4000mm direction on the first floor, streamlining the workflow.
Door-Platform Interlock: Equipped with interlocked mechanical doors that operate automatically with the platform, enhancing both safety and efficiency.
