The difference between fire elevator and ordinary elevator

The difference between fire elevators and ordinary elevators: ordinary elevators are not allowed to be used in the event of a fire. The fire elevator can be used by firefighters for fire fighting and rescue in the event of a fire.

Ordinary elevators do not have a fire fighting function, and people are prohibited from taking the elevator to escape in the event of a fire. Because when it is affected by high temperature, or power outage, or catches fire, it will inevitably affect the people who take the elevator, and even take their lives.

A fire elevator is an elevator with certain functions for firefighters to extinguish and rescue when a fire occurs in a building. Fire elevators usually have a complete fire protection function: it is a dual-circuit power supply, that is, if the building's working elevator power supply is interrupted, the emergency power supply of the fire elevator can automatically switch on and continue to run. It has an emergency control function, that is, when a fire occurs upstairs, it can accept instructions and return to the first floor in time, instead of continuing to accept passengers, it can only be used by firefighters. It reserves an emergency evacuation exit on the top of the car, in case the elevator door opening mechanism fails, you can also evacuate here. For the main part of a high-rise civil building, when the floor area does not exceed 1500 square meters, one fire elevator should be installed; when it exceeds 1500 square meters but less than 4500 square meters, two fire elevators should be installed; when the floor area exceeds 4500 square meters , There should be three fire elevators. The shaft of the fire elevator should be set up separately, and no other electrical pipes, water pipes, air pipes or ventilation pipes should pass through. The fire elevator shall be equipped with an antechamber, which shall be equipped with a fire door to make it have the function of preventing fire and smoke. The load capacity of the fire elevator should not be less than 800 kg, and the plane size of the car should not be less than 1m×1.5m. Its function is to be able to carry large fire-fighting appliances and place life-saving stretchers. The decoration materials in the fire elevator must be non-combustible building materials. Waterproof measures should be taken for the power and control wires of the fire elevator, and the doorway of the fire elevator should be provided with flooding waterproof measures. There should be a dedicated telephone in the fire elevator car, and a dedicated control button on the first floor.
