How to correctly use dual anti fall devices on tower cranes

Time:2024-10-15 09:08:19 Click:171

With the daily construction of high-rise buildings, the operating height of tower cranes is also constantly increasing. When the height of the tower crane exceeds the specifications of the anti fall device, the tower crane driver can use dual anti fall devices for safety protection. Some people may think that dual anti fall devices are worn simultaneously, but this is not the case. Below, Guanhang will explain the use of dual anti fall devices on tower cranes.

The major advantage of using dual anti fall devices is mainly reflected in the length, because if the length of the steel wire rope of the anti fall device is not enough, the tower crane driver can only release the protection when wearing the anti fall device halfway down, and climb the remaining height without safety protection. To ensure the safety of the tower crane driver throughout the entire process, we can adopt a method of lengthening the steel wire rope with dual anti fall devices.

When the first anti fall device is lowered to the midpoint, we can continue to fasten the safety hook of the second anti fall device that was previously fixed at this position, then release the restraint of the first anti fall device and fix the safety hook of the first anti fall device at this position. This way, we can safely lower the second anti fall device to the ground while wearing it. After lowering to the ground, secure the safety hook of the second anti fall device.

When we climb up, we can follow the reverse operation process. This is the important safety protection role that dual anti fall devices play when climbing tower cranes up and down. If you want to learn more about the use of anti fall devices, please feel free to consult the official website of Guanhang at any time.
