Information

Large industrial doors can be found everywhere in modern factories. However, the industrial door is heavy, and if there is a safety accident, the consequences are very serious, so its safety performance is very important.

 

Safety hazards in the use of industrial doors:

1. Do not use if the door is stuck.

2. Installation and wiring must be carried out in accordance with building construction standards and electrical standards.

3. The end of the door guide rail should be equipped with a mechanical limit device or a buffer booster to prevent the door from sliding out.

4. It is strictly forbidden to release the wrench during operation.

5. It is forbidden to operate the remote control where the door is not visible. At the same time, keep the remote control well and prohibit children from touching or playing to prevent danger.

6. Please fix the control box on a wall column 1.4 meters above the ground to prevent children from accidentally touching it.

7. Before repairing and moving the door opener of the industrial door, please cut off the power supply, and at the same time, make sure that the door body of the industrial door has been locked, and do it without the danger of falling under its own weight.

8. When the door is running, it is strictly forbidden for pedestrians and vehicles to pass or stay under the door.

 

 

The principle and function of the light curtain safety system of the industrial door:

Safety light curtain, also known as photoelectric safety protection device (also known as safety protection device, punching protection device, infrared safety protection device, etc.), is mainly composed of a light projector and a light receiver. The light emitter emits modulated infrared light, which is received by the light receiver, forming a protective net. When an object enters the protection net, and the light is blocked by the object, through the internal control circuit, the light receiver circuit responds immediately, that is, a signal is output in the output part, the door stops closing immediately and starts to open again. The most direct and efficient security solution can effectively solve 80% of the security problems in the use of industrial doors.

The safety light curtain system can be applied to high-speed rolling doors, combination doors, car wash doors, fire doors, cold storage doors, and freight elevator doors.

 

Why did we choose light curtains?

In order to prevent the functional failure of industrial doors, the most common safety devices on the market are mainly airbags and photoelectric switches.

 

Airbags mainly play a protective role and exist to protect the safety of pedestrians and vehicles. However, the controller needs to regularly check the airbag installed on the industrial sliding door to see whether its rebound function is normal when it encounters resistance, whether it is damaged by external force, and whether there is air leakage. If the airbag of the industrial door is found to be leaking or damaged by external force, it is necessary to replace the airbag with a new one immediately. Additionally, the system requires touching objects before being activated. In the case of a moving object, the damage may have been done by the time the door stopped opening. So he is more expendable.

 

The photoelectric switch requires no additional maintenance, but it's still not our preferred option because the photoelectric sensor doesn't cover the entire door opening. If a smaller object passes through the door, the photocell may not notice it. The light curtain covers the majority of the door opening, so we think it's the best choice for an industrial door security system.
