Mining Hangar Door

Overview

Specifically engineered for open-pit mining truck shop facilities, Shipyarddoor® provides robust, high-performance doors designed to withstand extreme conditions such as 24/7 operations, heavy dust, and sub-zero temperatures at high altitudes. These doors feature high insulation, minimal gaps, no ball bearings, and are easy to install or relocate—ideal for movable mining workshops.Developed with direct client feedback, the Flexible Giant system is built for durability and simplicity. Trusted from Mexico to Australia, Shipyarddoor® redefines expectations in the mining sector.

Key Points:

  • 24/7 Operations:
    Designed for continuous 24/7 use in mining environments using high-resistance fabric and durable gearbox systems.
  • Superior Sealing:
    Unique side sealing pockets and heavy-duty PVC fabric ensure excellent sealing, even in high winds. Bottom and side seals (rubber or brush) are weather-resistant and minimize air gaps.
  • Low Maintenance:
    No springs, ball bearings, or couplings—reducing failure risk from dust, impact, or collision. All components are selected for minimal maintenance.
  • Maximum Dimensions:
    Available up to 50,000 mm x 35,000 mm in a single piece; unlimited width possible with mullion systems.

Comprised of:

  • Steel Structure:
    Dual fabric layers fold in opposite directions, secured to horizontal steel or aluminum beams. Minimum thickness: 600 mm. Intermediate beams with self-lubricating polyamide tires retract without obstructing the door opening.
  • Bottom Beams:
    Engineered to support wind loads and intermediate beam weight. Ensures full sealing and stability under extreme weather.
  • Side Guides:
    Constructed from structural steel with bolt-fixed aluminum rails. Designed for weather-sealing and easy replacement if damaged.
  • Cable System:
    Operates with up to two steel cables per door. Cables are kink-free and guided by large-diameter sheaves to prevent stress or wear.
  • Fabric:
    VALMEX POLYMAR® Fire-ResistWeight: 900–1500 g/m² | Thickness: 2 mmTensile: 4300/4000 N (DIN 53354)Tear Strength: 500/500 N (DIN 53363)UV-resistant, long-life performanceOptional: Arctic, Soundproof, and Secure Fabrics.
  • Fire Resistance:
    Fabric meets DIN 4102-B1 standards: self-extinguishing and fire-retardant, ideal for mining safety compliance.
  • Speed:
    Standard speed: 20 cm/s; optional upgrade to 40 cm/s.
  • Insulation:
    Thermal U-value: < 0.9 W/m²·KSound insulation: 12 dB(A)Optional insulated fabrics available.
  • Wind Resistance:
    Operational wind resistance up to 140 km/h, closed position up to 180 km/h. Custom solutions available up to 230 km/h for hurricane zones.
  • Structural Loading:
    Designed to withstand wind pressure, suction, dead load, and seismic forces per environmental standards.
  • Drive System & Limit Switching:
    Double motors ensure balanced lifting. Redundant limit switches with built-in safety logic prevent overtravel. System includes slack rope detection for safe shutdown.
  • Safety:
    Certified to CE 89/106/EC, EN 13241-1:2003+A1:2011, EN 12978:2008. Standard features: load arrestors, wind locks, thermal resistance, buzzer, and warning lights.Optional: Bottom safety edge, pneumatic safety edge.
