Industrial Vertical Lift Door with Personnel Access Door

Project Overview
We recently installed a high-performance "industrial vertical lift door" at a logistics warehouse in Dongguan city. The door was designed for heavy-duty use, providing thermal insulation, security, and convenient access for personnel and forklifts. The client required a durable, energy-efficient solution with a sleek gray-striped design (RAL 7016) and an integrated man door for easy entry without fully opening the main door.  

Key Specifications & Features
1. Vertical Lift Mechanism & Chain Drive
   - Sectional lifting system: for smooth, space-saving operation.  
   - Chain-driven motor: ensures reliable performance in high-frequency industrial use.  
   - Lifting speed: 120–160mm/s, balancing efficiency and safety.  

2. Robust Door Construction
   - 40mm thick panels with 0.4mm zinc-coated steel (front & back).  
   - High-density polyurethane foam core for thermal insulation (U-value ≤ 2.5 kW/m2) and noise reduction (<45dB).  
   - Concealed joints & anti-pinch hinges (hot-dip galvanized) create a seamless, safe surface.  

3. Integrated Personnel Door
   - A built-in access door allows workers to pass through without fully opening the main door, improving energy efficiency and workflow.  
   - Reinforced frame and lock for security.  

4. Safety & Automation
   - Encrypted remote control (40m range) +manual override (<15kg lifting force).  
   - Obstacle detection & auto-reverse to prevent accidents.  
   - Backup battery for power outages.  

5. Durable Hardware
   - 82B high-tensile springs for smooth counterbalancing.  
   - 2mm galvanized steel tracks and bearing-mounted nylon rollers for long-term reliability.  

Why This Door Was Ideal for the Application
- Energy Efficiency: The insulated panels minimized heat loss, critical for temperature-controlled storage.  
- Space Optimization: Vertical lift design required no overhead clearance, unlike rolling doors.  
- Safety & Convenience: The **personnel door reduced unnecessary full-door openings, saving energy and time.  
- Low Maintenance: Galvanized components resisted corrosion in an industrial environment.  

Client Feedback
The warehouse manager praised the door’s quiet operation, durability, and security, noting that the gray-striped panels (RAL 7016) matched the facility’s modern aesthetic. The integrated access door proved especially useful for shift workers moving in and out frequently.  
This project demonstrates how a well-engineered industrial door can enhance productivity, safety, and energy management in logistics and manufacturing facilities.
