Dock Shelters & Sealers
DoorHan curtain and inflatable dock shelters provide an airtight thermal seal around vehicle trailers during loading and unloading. Engineered with tear-resistant PVC fabric and resilient aluminum frames to prevent energy loss and weather ingress.
Engineering Overview & Technical Standards
Energy-Saving Inflatable and Curtain Dock Shelters
DoorHan dock shelters provide an airtight thermal seal between the building door aperture and the rear of the parked commercial vehicle, shielding warehouse interior personnel, cargo, and material handling equipment from rain, wind, airborne dust, and extreme ambient temperatures. Essential for cold storage distribution, food processing hubs, and pharmaceutical facilities, our dock shelters preserve the cold chain and drastically lower facility HVAC costs.
Our product lineup features classical mechanical curtain shelters with collapsible aluminum scissor frames and premium inflatable dock shelters with high-speed radial air blowers.
Key Technical Specifications & Engineering Standards:
- Collapsible Front Frame: Hinged aluminum scissor frame retracts upon off-center truck contact, preventing structural wall damage and returning automatically to working position.
- High-Tear Fabric Materials: 3 mm thick heavy-duty multi-layer polyester fabric coated with wear-resistant PVC; high elasticity and tear resistance across -35°C to +70°C.
- Inflatable Air-Tight Sealing: Inflatable cushions adapt perfectly to diverse trailer heights and widths, achieving over 95% environmental sealing efficiency.
- High-Visibility Guide Chevrons: High-visibility vertical white alignment chevrons guide transport drivers into accurate dock bay centering.
- Integrated Top Drainage: Sloped top roof channel diverts rainwater runoff away from the active loading portal.
Quality Assurance & Engineering Compliance:
DoorHan dock loading systems, hydraulic levelers, and external dock houses comply strictly with European standard EN 1398 and CE Machinery Directive 2006/42/EC. Each leveler platform is factory proof-tested for dynamic point load capacities up to 100 kN with built-in emergency velocity fuses to prevent platform free-fall during unexpected truck departures. Full architectural pit installation drawings, civil foundation guides, and hydraulic line diagrams are available for engineering teams.
DoorHan dock shelters deliver substantial energy savings and ensure rigorous sanitary compliance across certified logistics facilities.
