Hard fast door

Hard fast door application site

Hard fast door——A new type of metal industrial door that is fast, energy-saving, sealed, efficient, wind-resistant, and environmentally friendly. It has high reliability and practicality, and its operating speed is more than 6 times that of industrial sliding doors. , with extremely high work efficiency and higher safety, hard fast doors are gradually replacing industrial sliding doors.

Turbine hard fast door can prevent outsiders from intruding At the same time, it can resist weather changes, can block indoor and outdoor air convection, and is used in frequent access passages. It is an ideal choice for industrial energy saving and consumption reduction.

Hard fast door turbine track

Twin spiral turbine

The aluminum alloy fast door adopts a double-spiral turbine structure. The guide rail is conducive to the acceleration of the door body, making the door body more stable when running at high speed, reducing the generation of noise, and improving the safety index. The single unit currently used on the market The turbine structure is prone to cracks in environments with large temperature differences, which can lead to safety accidents in serious cases.

Hard fast door control system

Control system

Lafayette fast door custom electric control box, stable performance, frequency conversion control, screen display, easy to monitor and troubleshoot. The Lafayette custom servo motor used, regardless of Whether in gas or dust environments, it can operate reliably in both hazardous areas.

Hard fast door lifting method

Upgrade method

Turbine spiral guide rail is a standard design specification and is the best solution when there is enough space above the door. When there is a certain limit to the depth of the upper space to compensate for the height of the upper space, the elliptical lifting method can be considered

Hard fast door panel

Door panel structure

Aluminum alloy quick door panel is double layerThe stretched aluminum plate is made of one-time composite, with fine pressed stripes on the surface, anodized and organic coloring, and polyurethane foam filling in the middle. The internal broken bridge design in the middle can improve the thermal insulation effect, prevent indoor and outdoor temperature loss, and save energy. The surface of the door panel has been treated with 5 layers of organic coloring, which greatly improves the corrosion resistance.

Security device

Lafayette fast door is equipped with infrared/safety light curtain and safety bottom edge. There are infrared/safety light curtains on both sides of the door frame. When there is an infrared/safety light curtain under the fast door When there is an obstacle, the door remains open; whenthe doorWhen an object passes through when descending, the door will open to the open position, and the descent will be delayed until there are no obstacles below. Sometimes, because the object is in the blind spot of infrared safety protection, the safety bottom edge is equipped so that when the door body is pressed against the obstacle below, the door body quickly rebounds to the most open position, effectively protecting the objects below or pedestrians to avoid accidents. At the same time, Lafayette fast doors also have safety devices such as radar induction, geomagnetic induction, remote control induction, Bluetooth radio frequency, pull rope switch, interlocking and other safety devices.
