The GG Door Electric Upward-Folding Door utilizes an electric drive system to open by folding upward, transferring space usage from the ground to overhead areas. This design offers significant space savings and provides a wide, unobstructed passage.
Structural Composition
Door Frame:
Each side of the frame is equipped with at least two guide rails. The lower sections of the rails run parallel, while the upper sections curve outward in arcs with varying starting points and angles. The top of the frame includes a storage compartment for horizontally stowing the folded door panels.
Folding Door Panels:
Consist of at least three hinged door sections, with concealed hinges between adjacent panels. The top panel features a central guide wheel, and additional guide wheels are installed at the junctions of even- and odd-numbered panels below, each engaging with different guide rails.
Power Mechanism:
Comprises a drive shaft, motor, and drive chains. The drive shaft is mounted above the frame, with two drive chains attached to both sides of the door. The upper ends connect to the drive shaft, and the lower ends fix to the bottom panel. The motor rotates the shaft, driving the chains to move the door.
Working Principle
The power mechanism drives the door panels upward via the chains. Guided by the rails and wheels, the panels fold sequentially into the overhead storage space for opening, and unfold downward for closing.
Product Features
Space Efficiency:
The upward-folding design maximizes overhead space utilization, minimizing ground obstruction and maximizing passage width.
Smooth Operation:
Equipped with synchronized lift mechanisms (e.g., multiple belts on a single drum), ensuring quiet, stable operation with audio-visual open/close indicators.
Excellent Sealing:
Full perimeter sealing with tight frame contact, insulated edges, and optional bottom air-tight for enhanced thermal and acoustic insulation.
Safety & Reliability:
Includes safety limit systems, optional infrared sensors, and anti-fall components to ensure secure operation.
Applications
Ideal for large-span openings, especially where side or overhead space is limited. Commonly used in small hangars, garages, hotels, and other wide-entrance facilities.
