Product Overview

Qingdao XWELL Intelligent Door and Window Technology Co., Ltd. launchesLarge Machine Shed Door: Large Swing DoorAn intelligent industrial door designed specifically for large spaces such as aircraft hangars and maintenance sheds. The product is composed of multiple door panels connected by hinges, which open by moving along an arched track, featuring advantages such as small space occupation, strong wind resistance, and smooth operation. Typical cases include the police helicopter side rotation hangar door project, which fully verifies its applicability and reliability in helicopter hangar scenarios. As a benchmark case in the industrial door field in Henan, this product integrates advanced technologies in structural design, transmission system, and safety protection, providing an efficient and secure door solution for large facilities.

Main Product Features

Structural design: Stable and flexible, adaptable to diverse needs.

Adopting an overhead suspended structure, equipped with guiding tracks at the bottom, the door consists of multiple narrow panels connected by hinges. This design not only ensures operational stability but also allows for flexible assembly according to the size and shape of the door opening, catering to customized needs in different scenarios. For instance, in the case of a police helicopter hangar, the modular assembly of the door panel adapts to non-standard door openings, showcasing high adaptability.

2. Operation modes: Three modes, easy operation

The door moves horizontally along the doorway and side wall with a 90-degree track, significantly saving indoor space. It supports three operation modes: manual mode for emergencies or power failure situations; electric mode for automatic opening and closing driven by a motor; and remote control mode for convenient operation from a distance. The three modes switch seamlessly to meet different operational requirements.

3. Transmission System: Precise and stable, reliable power

Based on structural differences, two solutions are provided: rack and pinion drive and wire rope drive. The door opener can be installed at the head or tail of the door. Through optimized transmission ratio and power distribution, it ensures smooth opening and closing of the door without jamming. For example, in the case of large machine sheds, the rack and pinion drive system, combined with high-power motors, successfully drives doors weighing several tons, with operating noise below 65 decibels.

4. Sealed System: Multi-level Protection, Environmental Isolation

The door periphery, bottom, and center are all embedded with high-elastic sealing strips, forming a triple protection barrier. Measured results show that the sealing system can effectively block dust, rainwater, and sand from entering, while reducing the air exchange between the interior and exterior of the machine room, maintaining internal temperature fluctuations within ±2℃ and humidity stability at 40%-60%RH, providing an ideal storage environment for precision equipment.

5. Security System: Intelligent Early Warning, Active Protection

Equipped with infrared anti-climbing devices and collision sensors, a comprehensive safety network is established. Upon detecting illegal climbing or operational obstacles, the system immediately triggers an alarm and stops the door movement, preventing personnel injuries and equipment damage. In a military hangar case, the safety system successfully identified an employee who mistakenly entered the track, timely braking to avoid an accident.

6. Material and Craftsmanship: Durable and anti-corrosive, extended lifespan

The door frame is made of 304 stainless steel or high-strength aluminum alloy, with an anodized surface treatment for corrosion resistance up to C4 level, suitable for coastal or high-humidity environments. The hinges and hinges use self-lubricating bearings to reduce wear and maintenance frequency. According to long-term tracking data, the average service life of the product exceeds 15 years, far exceeding the industry average.

Product Detailed Parameters

Application Scope

Aviation field

Suitable for civil aviation hangars, military helicopter hangars, general aviation maintenance bases, etc. For example, Qingdao Jiaodong International Airport's wide-body hangar uses XW-SZM type side-hinged doors, with a single door width of 2.8m and a height of up to 12m, meeting the access requirements for large aircraft such as the A380.

2. Industrial Storage

Large logistics warehouses, shipyard gates of shipyards, wind power equipment storage facilities, etc., where high space utilization is required. In a case of a wind power enterprise, replacing the traditional swing doors with side-tilting doors increased the available area inside the storage by 18%, significantly enhancing storage efficiency.

3. Special Facilities

Nuclear power plant protective doors, temporary tunnels construction doors, emergency rescue vehicle storage, etc., which require rapid opening and closing and high sealing properties. In a certain nuclear power plant project, the side-rotating door equipped with radiation shielding lead plate has become the first industrial door case to obtain domestic nuclear-grade certification.

Frequently Asked Questions (FAQ)

Q1: Where does the side-hinged door have a spatial advantage over the swing door?

A: Sliding doors require space for front and rear swinging during opening, while side-hinged doors move along the track to the sides, needing only an additional 100mm of lateral space beyond the door thickness. Taking a 10m wide door opening as an example, a swinging door requires at least 12m of clear width, while a side-hinged door only needs 10.2m, saving space by 15%.

Q2: How is the wind resistance of the door panel ensured?

The door body is constructed with a double-layer skeletal structure, filled with polyurethane foam material inside, covered with 0.8mm thick metal plate on the surface, with the overall bending stiffness increased by 40%. At the same time, the bottom guide wheel and track adopt an embedded design, which can resist the lateral force generated by 12-level strong wind, ensuring the stability of the door body under extreme weather conditions.

Q3: What should I do if the electric mode suddenly loses power?

A: The system is equipped with an uninterruptible power supply (UPS), which allows the door to complete the current opening and closing action or return to its initial position in case of power failure. Moreover, the manual release device enables operators to manually switch the door on and off using a mechanical handle, preventing the hangar from being sealed for an extended period due to power outages.

Q4: What operations are required for daily maintenance?

A: It is recommended to check the hinge lubrication quarterly, replenish with high-temperature resistant lithium-based lubricant; clean the track of foreign objects and inspect the aging degree of the sealing rubber strip annually; replace the transmission chain or钢丝绳 once every three years. Qingdao Xinwei'er offers national warranty service and allows for scheduling a professional team to provide on-site maintenance.

Q5: Can we customize non-standard sizes or special functions?

A: Supports fully customizable production, including door size, material, color, transmission method, etc. Special functions such as explosion-proof design, low-temperature start (-30℃), and intelligent interlock control can all be achieved. A specific requirement document is required, and engineers will provide a personalized solution.
