Client Background

TE Connectivity (Dongguan) Co., Ltd. is a core manufacturing base of TE Connectivity in South China, specializing in the R&D and production of high-frequency data signal harnesses, communication consumer electronic harnesses, and connector assemblies. The logistics center at its Houjie factory handles over 60 inbound and outbound shipments daily, covering vehicles from light vans to heavy container trucks. With high-frequency cross-traffic between personnel, forklifts, and trucks at the dock, the facility faces significant pressure on both safety management and operational efficiency.

Core Challenges

1. Multi-Vehicle Compatibility Issues: Traditional hook-style restraints failed to secure older delivery vehicles without standard rear bumpers. Manual wheel chocks were inefficient and unstable due to varying tire sizes, posing safety risks.
2. High Safety and Compliance Requirements: The electronics manufacturing industry demands strict adherence to occupational health and safety standards, requiring elimination of risks such as truck slippage and accidental departures that could cause cargo damage or personal injury.
3. Operational Efficiency Bottlenecks: Manual truck securing took over 12 minutes per vehicle, causing severe congestion during peak hours and impacting the factory’s raw material turnover and finished goods delivery efficiency.

Customized Solution

Maidien deployed the GWL-3000 Automatic Wheel Restraint at its loading docks, delivering a targeted safety upgrade:

• Universal Vehicle Compatibility: High-strength steel locking arms automatically adapt to tires from 500mm to 1200mm in diameter, requiring no rear bumper. With a locking force of 30,000N, it withstands sudden truck slippage impacts.
• Automated Workflow: The system automatically detects the truck and extends the locking arm once positioned. Unlocking is done with a single confirmation after operations, reducing securing time to under 3 minutes per truck.
• Safety Interlock System: Built-in audible/visual alarms prevent dock doors and levelers from operating until the truck is securely locked, eliminating human error. The system can also integrate with warehouse management systems for real-time monitoring.
• Durable & Low-Maintenance Design: IP67-rated for harsh dock environments, with modular components for quick replacement. Mean Time Between Failures (MTBF) exceeds 5,000 hours, reducing long-term maintenance costs.

Project Results

1. Zero Safety Incidents: Truck slippage and accidental departure risks were completely eliminated, ensuring full compliance with ISO 45001 standards and TE Connectivity’s global safety specifications.
2. Significant Efficiency Gains: Dock throughput increased by 35%, handling 15 more trucks daily during peak hours and greatly optimizing supply chain efficiency during busy seasons.
3. Effective Cost Reduction: Cargo damage rates dropped by 90%, maintenance labor costs reduced by 45%, and the project delivered full ROI in under 18 months.
