What are the specific differences between fall suspension safety harnesses and area restriction safety harnesses

There are obvious differences in the design and use of fall suspension safety harnesses and area restriction safety harnesses, which are mainly reflected in their design purpose, use environment, structural characteristics and working principles. The following is a detailed comparison of the two safety harnesses:

1. Design purpose

Fall suspension safety belt: mainly used to prevent high-altitude workers from falling accidents. Its design purpose is to quickly lock and withstand the impact force generated by the fall when a person falls accidentally, thereby protecting the life safety of the person.

Area restriction safety belt: mainly used to restrict the activities of workers in a specific area to prevent them from entering a dangerous area or leaving a safe area. Its design purpose is to reduce the risk of contact with dangerous objects or entering a dangerous area by limiting the range of activities of people.


2. Use environment

Fall suspension safety belt: widely used in high-altitude operations such as electricity, telecommunications, and construction. In these environments, workers need to perform high-altitude operations frequently, so fall suspension safety harnesses become essential protective equipment.

Area restriction safety belt: more used in industrial production, construction and other scenes. In these environments, workers need to work in a specific area, and the area-restricted safety belt can effectively limit their range of movement and ensure safety.

3. Structural features

Falling suspension safety belt: usually equipped with a sturdy hook and anti-fall device. These devices can be quickly locked when a person falls accidentally, and withstand the impact force caused by the fall. In addition, the falling suspension safety belt also has high comfort and flexibility to adapt to different working environments and work needs.

Area-restricted safety belt: usually equipped with a rope or belt with adjustable length, the size of the restricted area can be adjusted as needed. Some area-restricted safety harnesses are also equipped with a telescopic anti-fall device, which can move freely within a certain range, but when a person approaches a dangerous area, the restrictive function of the telescopic device will prevent the person from moving forward.

4. Working principle

Falling suspension safety belt: When a worker falls accidentally, the anti-fall device will quickly lock the safety rope to prevent the person from falling further. The working principle of this safety belt is based on the principle of mechanics, and the locking device is used to withstand the impact force caused by the fall.

Area-restricted safety belt: The restriction function is achieved through the tightener and pretensioner of the safety belt. When a vehicle collides or brakes suddenly (for area-restricted seat harnesses for vehicles), the seat belt retractor will quickly tighten the seat belt to fix the driver and passenger's body tightly to the seat. At the same time, the pretensioner will perform an emergency stretch before the seat belt is tightened to eliminate the initial gap between the seat belt and the driver and passenger, ensuring that effective protection can be provided immediately when a collision occurs. For industrial area-restricted seat harnesses, the working principle is to limit the range of movement of people through telescopic devices or adjustable ropes.

In summary, there are obvious differences between fall suspension seat harnesses and area-restricted seat harnesses in terms of design purpose, use environment, structural characteristics and working principles. In practical applications, the appropriate type of seat belt should be selected according to the specific working environment and safety requirements.
