Speed differential anti fall device is a part of the simple anti fall device for transmission lines

The majority of power operations involve high-altitude work, and the majority of high-altitude work involves the operation of transmission line towers. The task of transmission line tower operations is heavy, the location is high, and a large amount of maintenance work is required. In order to improve the safety of high-altitude workers climbing towers and gantries without affecting their work efficiency, power workers use speed differential fall arresters, safety ropes, and other components to form a double safety belt protection method at the work site.

The double safety belt protection method is an advanced anti fall device, which is used in combination with anti fall devices by fixing guide cables on steel structures such as transmission line towers, substation frames, gantry frames, and high-rise buildings.

When an electric worker accidentally falls, the anti slip teeth on the fall arrester will bite, increasing the friction between the bite teeth and the guide cable. The bite teeth will instantly press the guide cable only onto the slide of the fall arrester, preventing the fall arrester from sliding down along the guide cable and ensuring that high-altitude workers are suspended in mid air without falling.

In this new and simple anti fall device, as long as the staff wears the speed differential anti fall device, grasps the main materials of the iron tower, steps on the iron tower foot nails or uses the cement pole foot buckle well, they can climb with confidence, which not only improves the safety factor but also enhances work efficiency, and the installation and use process is also very convenient.
