External Reloading Vestibules: Architectural Space & Thermal Efficiency
In high-performance logistics buildings, installing dock levelers and sectional doors inside the primary building perimeter can create internal thermal bridges and consume valuable floor storage space. Loading Dock Houses (Reloading Vestibules) solve this by relocating the entire docking assembly—dock leveler, dock shelter, and sectional door—outside the main facility walls, preserving interior storage space and creating an airtight thermal buffer zone.
1. Dock House Structural Engineering & Thermal Cladding
DoorHan reloading houses are self-supporting modular steel structures installed directly against the exterior warehouse facade:
- Heavy-Duty Welded Frame: Engineered from high-strength galvanized steel sections designed to absorb dynamic forklift loads and exterior snow/wind pressures.
- Insulated Sandwich Panel Enclosure: Clad in 40 mm or 80 mm polyurethane foam sandwich panels, forming a complete thermal barrier that keeps rain, wind, and ambient heat away from loading goods.
- Space Optimization: Reclaims up to 15 m² of interior floor space per loading bay, allowing racking to be placed directly up to the warehouse exterior wall.
- Integrated Drainage & Sloped Roof: Built-in water management gutters direct stormwater runoff safely away from docking vehicles.
2. Inflatable Dock Shelters (D.SH-INF Series)
While standard curtain dock shelters provide mechanical brush/flap sealing, temperature-controlled pharmaceutical and deep-freeze logistics facilities require near 100% airtightness. DoorHan inflatable dock shelters deliver superior sealing efficiency:
- Radial Blower Inflation in 15 Seconds: When a truck backs into the bay, powerful internal blowers inflate heavy-duty Cordura cushions around the top and side panels of the trailer body within seconds.
- 98% Airtight Perimeter Seal: Inflatable cushions conform perfectly to irregularities, hinges, and ribbed trailer walls, preventing air infiltration and maintaining cleanroom hygiene.
- Automated Retraction: When loading is completed, the blowers deactivate, and internal counterweights/springs rapidly retract the cushions back into protective wall housings before the vehicle drives away.
3. Integrated Dock Control Systems
DoorHan master loading bay control panels interconnect the dock leveler, inflatable shelter, sectional door, and exterior traffic light into a single foolproof safety sequence:
- 1. Truck docks → 2. Inflatable shelter inflates → 3. Sectional door opens → 4. Dock leveler deploys onto truck bed → 5. Exterior traffic light turns Red → 6. Loading proceeds under complete climate protection.
