Introduction
In modern logistics, warehousing, and retail distribution, maintaining energy efficiency and cargo protection during loading operations is increasingly important. A dock shelter provides a vital barrier between the warehouse and the truck, reducing outside air exchange, protecting goods, and enhancing workplace comfort.
Among the different types, the Mechanical Dock Shelter (MDS) remains one of the most cost-effective and reliable solutions. With a simple structure, strong fabric curtains, and durable foam-filled panels, it provides consistent sealing performance suitable for standard trucks in everyday operations.
Product Overview
A Mechanical Dock Shelter consists of an aluminum alloy frame, flexible top and side curtains, and durable foam reinforcement.
When a truck reverses into the dock, the top and side curtains press against the vehicle body, forming a barrier that reduces heat loss, prevents dust entry, and shields goods from wind and rain.
Key Features
- Strong and lightweight aluminum alloy frame.
- Reinforced PVC fabric with good abrasion resistance.
- Foam-filled curtains providing flexible compression.
- Airtightness performance of up to 70%.
- Suitable for a wide range of truck dimensions.
How Does a Mechanical Dock Shelter Work?
Working Principle
- The truck reverses toward the loading bay.
- The top curtain adjusts to different truck heights (1000–1200 mm).
- The side curtains compress against the truck body (600 mm).
- A semi-sealed environment is formed, reducing dust, wind, and rain infiltration.
Technical Specifications
The following table presents the standard specifications for Mechanical Dock Shelters:
| Size (W × H) | Top Hanging Curtain | Side Hanging Curtain | Frame Structure |
| 3200 × 3400 mm | 1000–1200 mm | 600 mm | Aluminum alloy |
| 3400 × 3400 mm | 1000–1200 mm | 600 mm | Aluminum alloy |
| 3400 × 3600 mm | 1000–1200 mm | 600 mm | Aluminum alloy |
| 3600 × 3800 mm | 1000–1200 mm | 600 mm | Aluminum alloy |
Advantages of Mechanical Dock Shelters
1. Cost-Effective Solution
Mechanical dock shelters are more affordable than inflatable types while still providing effective sealing for general use.
2. Energy Efficiency
Although not fully airtight, they reduce temperature loss by around 70%, lowering energy costs for climate-controlled warehouses.
3. Long Service Life
With a simple structure and durable aluminum alloy frame, mechanical dock shelters are resistant to wear and require minimal upkeep.
4. Adaptability to Standard Trucks
The adjustable top curtain and flexible side curtains make them suitable for common truck sizes.
5. Enhanced Protection
By limiting dust, wind, and rain entry, they improve workplace comfort and cargo safety.
Application Scenarios
Warehouses & Distribution Centers
Mechanical dock shelters help improve loading efficiency while reducing energy consumption.
Retail Chains & Supermarkets
