The pin‑type flexible stacking door is specially engineered for super‑large industrial door openings. It adopts unique overhead pin‑shaped stacking folding structure, completely cancels ground rail, so all kinds of large vehicles and heavy equipment can pass without barriers. Multiple groups of high‑strength truss wind‑resistant beams are embedded inside the door curtain, cooperating with heavy‑duty electric hoist drive system. Double‑layer PVC‑polyester composite fabric curtain provides excellent wind‑resistance, dust‑proof, waterproof and partial thermal‑insulation performance. Equipped with complete anti‑fall safety protection system, it solves the difficulty of super‑large‑size door application in heavy‑industry scenarios. Widely used for aircraft hangars, shipyards, sandblasting & painting workshops and large‑scale manufacturing plants. Support full‑custom dimension, fabric color, observation window and safety configuration for global industrial projects.
Pin‑type flexible stacking door belongs to overhead folding flexible large door series. Different from ordinary rolling doors, it folds the whole curtain upward in pin‑shape and stores above the doorway when opening, without occupying side‑space. No‑ground‑rail design avoids ground‑rail damage caused by heavy‑vehicle rolling. Internal truss beams undertake wind pressure, making it suitable for outdoor exposed large openings. This product focuses on solving large‑span access requirements for heavy‑industry, aerospace and ship‑building projects.
Double‑layer high‑strength PVC‑polyester fabric curtain; multi‑group galvanized steel truss wind‑resistant beams arranged in pin‑type layout; top heavy‑duty electric hoist lifting system; side heavy‑load guide rails; wire‑rope lifting mechanism; anti‑fall safety locking device; double‑limit travel control; infrared safety photocell and acousto‑optic warning lamp. Optional transparent observation window embedded on curtain. Frequency‑conversion control cabinet supports emergency manual release under power‑off status.

Steel truss beam cutting & welding & anti‑rust treatment → guide‑rail processing → high‑strength PVC fabric hot‑welding splicing → pin‑type beam‑curtain assembling → hoist & wire‑rope system installation → safety anti‑fall device fitting → control cabinet wiring → whole‑door cycle debugging & wind‑load simulation inspection → export packing.
Fabric tensile‑strength and fire‑retardant inspection; steel‑truss welding & anti‑rust test; whole‑door lifting cycle test; anti‑fall locking function simulation test; limit‑position calibration; safety‑device full‑function checking before shipment.
Sufficient overhead headroom space must be reserved above doorway. The wall or steel‑structure frame must bear the total weight of door and lifting system. Reserve power supply for hoist and control cabinet. Provide complete installation drawings and technical specification; local construction team can finish on‑site assembly.
Clean curtain surface dust and dirt regularly. Check truss‑beam welding points, wire‑rope abrasion condition and fastening bolts every 6‑12 months. Strictly inspect anti‑fall safety locking device periodically. Replace aged curtain fabric and worn wire‑rope timely; do not operate door under overload condition.
Please provide doorway width & height, local wind‑load requirement, installation environment and special configuration demands. We will offer customized quotation and structural‑design proposal for pin‑type flexible stacking door projects.
