According to different operation and wearing types, it can be divided into full body safety belt and half body safety belt:
1. Full body harness, that is to say, the whole body is covered with safety belt, equipped with waist, chest and back suspension points. It can be disassembled into a half body safety belt and a chest safety belt. The biggest application of full body safety belt is to enable rescue workers to work in a "head down" manner. Second, it is unnecessary to consider the safety belt slipping. For example, in deep well rescue, rescue workers need to "head down" and get close to the trapped people.
2. Half body hasty harness, that is, the safety belt only covers the half of the body (generally the lower part of the body, but it is like a chest type safety belt, which is used for the protection of the upper part of the body). Its use scope is relatively narrow compared with the whole body safety belt, and it is generally used for "seat suspension".
The parameters of safety belt are working tension (WS) and bursting tension (BS). According to different standards and manufacturers, the above parameters are also different.
