Model 016 Heavy-Duty Vertical Lifting Fabric Door
The Model 016 Heavy-Duty Vertical Lifting Fabric Door is engineered for large-scale openings and demanding industrial environments subject to extreme moisture, high dust concentrations, heavy wind loads, and severe temperature fluctuations.
Constructed with dual-layer vinyl-coated polyester fabric separated by internal structural aluminum beams, Model 016 delivers exceptional wind resistance, structural rigidity, and thermal buffer insulation. During opening, the door leaf folds upward into a compact stack beneath the header casing, requiring minimal headroom and side clearance even on oversized openings up to 16,000 mm (W) × 12,000 mm (H). Individually engineered for project-specific structural loads, it provides reliable operation with minimal maintenance requirements.
Key Engineering Features
- Dual-Layer Fabric & Wind-Resistant Intermediate Beams
- The door leaf consists of two layers of 1100 dtex vinyl-coated polyester clamped to horizontal aluminum intermediate beams. This creates an internal insulating air pocket and transfers positive/negative wind loads directly to the heavy-duty vertical side guides, resisting wind pressures from 0.7 kPa to 1.6 kPa (Class 3–5 per EN 12424).
- Four-Hook Mechanical Safety Arrestor System
- Heavy-duty safety catches are mounted to both ends of the bottom steel profile. The two upper hooks function as positive wind locks when the door is closed, while the two lower hooks serve as anti-drop arrestors that instantly engage the vertical guide channels if a lifting belt slackens or severs.
- Engineered for Severe Environmental Conditions
- Rated for continuous operation in wind speeds up to 20 m/s and standard ambient temperatures from -35°C to +70°C (extendable to -45°C with optional Arctic fabric).
- High Environmental Tightness & Acoustic Attenuation
- Full perimeter sealing across top, sides, and bottom achieves Class 3 Water Permeability and an air leakage rate of 12 m³/(m²·h) (Class 2, ref. EN 13241). The dual-curtain air cavity provides 15 dB Rw (ISO 717) sound reduction.
- Soft Optical Safety Bottom Seal
- The bottom aluminum/steel profile features heavy-duty sealing rubber and an integrated optical safety edge sensor that reverses door movement upon contacting an obstruction.
- Reliable Electric Drive & Dual-Motor Capability
- Powered by a dedicated electric hoisting drive system (configured with dual synchronized lifting motors for door heights exceeding 15 meters) to ensure smooth and controlled vertical travel at 0.2 – 0.3 m/s.
- IP-Rated Heavy-Duty Control Enclosure
- Supplied with a dedicated Model 0451 control enclosure (carbon steel or stainless steel, 400 × 500 × 200 mm) featuring built-in safety interlocks, pushbuttons, and expandable interfaces for automated access, radar, and facility BMS integration.

Specialized Curtain Options
Model 016 can be configured with tailored fabric options for specific facility requirements:
- Standard PVC Curtain: Double-layer tear-resistant 1100 dtex polyester fabric resistant to mechanical wear and welding sparks. Available in Blue or Grey (Optional: Yellow, Red, White).
- Arctic Curtain: Engineered for cryogenic cold storage and sub-zero climates down to -45°C. Supplied in RAL 5010 Blue.
- Acoustic Curtain: Integrated multi-layer acoustic lining (approx. 2 m height) fitted between outer curtains, reducing industrial noise transmission.
- Heat-Resistant / Chemical-Resistant Curtain: Engineered with specialized coatings (3 material formulations available) to withstand radiant heat, slag, or corrosive chemical environments.
- Security Curtain: Features internal woven galvanized steel wire mesh between curtain plies for enhanced cut and intrusion resistance.
Architectural Mounting Options
Model 016 can be adapted to various structural layouts:
- Interior Wall Mounting (Recommended): Positioned on the interior wall face to completely protect drive mechanisms and vertical guides from exterior elements.
- In-Jamb Mounting: Positioned directly inside the structural door opening to accommodate tight side-room layouts (protective bollards recommended for guide rails).
- Exterior Wall Mounting: Installed on the exterior building facade where interior overhead space is restricted or indoor environmental conditions are harsh.
Industrial Applications
- Aviation Hangars & Shipyards: Large-scale portals for aircraft maintenance bays, shipbuilding halls, and dry docks.
- Mining & Mineral Processing: Heavy truck maintenance workshops, raw material storage facilities, and abrasive dust containment bays.
- Heavy Manufacturing & Metal Smelting: Steel mills, foundries, and fabrication plants exposed to high ambient heat or weld sparks.
- Waste Treatment & Composting Plants: Large doorways requiring positive odor containment, corrosion resistance, and high wind resistance.
Frequently Asked Questions (FAQ)
A: The safety arrestors are mounted at both ends of the bottom beam. During normal closed positioning, the two upper hooks engage the vertical guides to act as structural wind locks. If a lifting belt loses tension or snaps, the two lower spring-loaded arrestor hooks instantly clamp into the guide channels to prevent the door leaf from dropping.
A: The door leaf utilizes internal structural aluminum intermediate beams that securely clamp the dual-layer fabric. These beams distribute external wind pressures across the entire door width directly into the extruded aluminum side guide rails, providing certified resistance from 0.7 kPa to 1.6 kPa (Class 3–5 per EN 12424).
A: For installations where the clear door height exceeds 15 meters, or where project-specific structural weights demand additional lifting capacity, Model 016 is equipped with synchronized dual-motor hoisting units to ensure balanced, stable, and reliable vertical stacking.
A: Yes. The standard PVC curtain operates reliably between -35°C and +70°C. For extreme cold-climate installations down to -45°C, an optional low-temperature Arctic curtain (RAL 5010) is available. For high-temperature radiant heat or chemical exposure, specialized heat-resistant fabric coatings are available.
A: When opening, Model 016 lifts from the bottom, causing the fabric plies and intermediate beams to fold neatly into a vertical stack directly beneath the header casing. It requires zero rear ceiling track horizontal run and minimal side clearance, making it suitable for oversized portals where ceiling clearance is occupied by overhead cranes or ductwork.
