Safety guarantee of traction gantry elevator: electrical and mechanical dual protection mechanism

In modern urban life, elevators have become an indispensable tool for connecting the floors of high-rise buildings, and their safety is directly related to the life safety of every passenger. As a common type of elevator in high-rise buildings, traction gantry elevators not only undertake the task of efficient transportation, but also demonstrate advanced technology and design concepts in terms of safety assurance.

Electrical and mechanical dual safety devices: double insurance to protect life
The reason why traction gantry elevators can stand out among many types of elevators is largely due to their perfect safety system. This system is composed of electrical safety devices and mechanical safety devices, which complement each other and provide double protection for elevator operation.

The electrical safety device is the core of intelligent elevator monitoring. It monitors the operating status of the elevator in real time through a series of sensors and controllers, including key parameters such as power supply, car position, speed, etc. Once a power outage or other abnormal situation is detected, the electrical safety device will immediately trigger a warning signal and automatically start the emergency braking procedure. This process is completed almost in milliseconds, effectively avoiding the risk of elevator loss of control or falling due to power failure.

The mechanical safety device is the last line of defense for elevator safety. Even in the event of an electrical system failure, the mechanical brakes can respond quickly and physically lock the elevator car to prevent it from free falling or unexpected movement. These brakes are usually made of high-strength materials and are rigorously tested and calibrated to ensure reliable operation in any emergency situation. In addition, there are buffer devices in the elevator shaft to further absorb possible impact forces and protect passengers from injury.

Strategies for dealing with power outages: both prevention and emergency

In the face of unforeseen power outages, the traction gantry elevator's response strategy reflects the principle of both prevention and emergency.

Preventive measures are mainly reflected in daily maintenance and monitoring. Elevator maintenance personnel regularly conduct a comprehensive inspection of the electrical system, including status assessment of components such as cables, switches, and relays to ensure that all electrical connections are reliable and free of hidden dangers. At the same time, using advanced Internet of Things technology, the elevator management system can upload operating data to the cloud in real time to achieve remote monitoring and early warning. Once an abnormality is found, the maintenance team will be notified immediately for processing.

Emergency measures focus on immediate response when power is interrupted. The power supply department usually notifies the planned power outage information in advance, and the elevator service company formulates a detailed emergency plan based on this. Before a power outage, the elevator service personnel will manually park the elevator at the nearest floor one by one, open the car door, and ensure the safe evacuation of all passengers. In the event of a sudden power outage, the emergency lighting and communication equipment in the elevator will be activated immediately to provide passengers with necessary lighting and external communication channels. At the same time, the electrical and mechanical safety devices will also automatically intervene to ensure that the elevator is in a safe state until the power is restored.
