The sliding hangar door is designed for large hangars and is highly reliable and energy efficient. It consists of multiple independent door bodies that can be opened by sliding in one or two directions, with flexible opening width, thus reducing construction costs. The main components include frame, shell, track, running wheel, guide wheel, seal, drive transmission system, electrical control system and safety protection device. It is suitable for airport aircraft maintenance hangars, large manufacturing workshops and aircraft manufacturing plants.
The driving motor of the push-pull hangar door has two modes: direct drive and indirect drive. Direct drive is when the motor directly drives the wheel, using static friction to transmit power. It is suitable for light and small doors and has the characteristics of simple structure, fast response, and easy maintenance. Indirect drive is when the motor drives the winch, using the friction between the wire rope and the winch pulley for transmission. It is suitable for heavy doors or scenes that require precise control, but the structure is complex and the maintenance requirements are high.
The choice of drive mode needs to comprehensively consider factors such as the size, weight, door opening speed requirements, and maintenance capabilities of the door.
The control part is the core of the safe and efficient operation of the hangar door. It uses PLC as the core component to achieve precise control and multiple safety protections, including maintenance door interlocking, to ensure the safety of personnel and equipment.
A safe inching button mode is adopted to avoid misoperation, and an automatic fire alarm function is set to ensure rapid evacuation.
Equipped with an advanced touch screen, it displays door status and alarm information in real-time, improves operational convenience, intuitiveness, and system intelligence, and significantly enhances the safety and reliability of the hangar door.
The main body of the electric sliding hangar door is as follows:
1. Anti-collision device: The door leaf stops automatically when it accurately senses obstacles to prevent accidental injuries.
2. Anti-surge suppression: Protect the motor and electrical system from surges.
3. Door stop detection: When the door leaf is blocked, the relevant sensor can identify and automatically stop the door to prevent the door from being forced open.
4. Motor short circuit protection: Block a series of safety accidents caused by motor short circuit.
5. Power supply phase loss protection: Stabilize voltage and current and other related electrical problems.
6. Limit device: Let the door leaf stop accurately at the set position to prevent over-positioning.
7. Anti-derailment device: Prevent major accidents caused by door leaf derailment.
8. Sound and light alarm: Accurately alarm and warn of things that appear in the door body.
9. Operation warning light: Within 5s~10s before the door body opens and closes, an sound and light alarm appears to warn or prompt relevant personnel to be safe and alert.
10. Small door switch interlocking device: The system is equipped with large and small door switch interlocking devices so that the door body can operate in an integrated manner.
Electric lift hangar doors are widely used in airport aircraft maintenance hangars, large manufacturing workshops, aircraft manufacturing plants, military base hangars, aviation exhibition centers and logistics centers.
High reliability, good energy saving effect, flexible opening width, low construction cost, efficient drive system, advanced control system, complete safety system, simple maintenance, strong applicability and other advantages ensure long-term stable operation, improve operating efficiency and safety, and meet the customized needs of different scenarios.
