It is better to check the safety door of the construction elevator frequently

The powerful role of construction elevator safety doors in construction There are two main types of construction elevator safety door systems. Mechanical brake type: There is a small exposed door panel between the car door and the landing door, about 3 to 4 cm. When the door is closed, someone or something in the middle will first meet the safety door. This will cause the door to open again so no one will be hurt.

Construction elevator safety door, optical brake type: usually have infrared laser sensor. The principle is very simple, just like the welcome door. The laser safety device in the elevator is installed between the landing door and the car door. When the door is closed, as long as there is an obstacle in the middle that reflects the laser, it will command the door to open automatically again. The possible risks of the elevator generally include: Squeeze, impact and fall, shear; people are hit, and the car exceeds the limit stroke to cause impact.

Car overspeed or fall due to broken rope; structure damage due to material failure and loss of strength, etc. In addition to full consideration of the rationality and reliability of the structure, the reliability of the electrical control and drag In view of various possible risks, set up safety devices to ensure the smooth progress of the construction and avoid safety accidents caused by the protective doors of the elevator floors under construction.

The key to solving this problem is to strictly control the closing of the protective door. We persevere in strengthening management on this issue, and set up safe and reliable protective doors that can be closed at all times to effectively curb the occurrence of safety accidents from the source. It can be seen that construction elevators The protective door plays a very important role in construction, so everyone must check the construction elevator protective door regularly during the construction process to avoid accidents.
