In high-altitude operations, in order to ensure safety, the use of safety protection equipment is mandatory. Usually, belt-type or half-length safety belts are used. In this layer of safety protection, there is only one hook on the safety belt and no buffer. When falling from a place, the belt or half-length seat belt is likely to cause damage to the human lumbar spine.
In addition, the use of ordinary seat belts may cause insufficient safety clearance distance, or frequent use of seat belt hooks affects work efficiency. In order to solve these problems, fall arresters can be used.
The retractable fall arrester, also known as the speed difference anti-dropping device, is a product that can protect people when falling from a high altitude.
The fall arrester adopts the method of high-hanging and low-hanging under our normal working conditions, and its safety rope is free to expand and contract with our body. Under the action of the internal mechanism of Chenghua fall arrester, it is in a semi-tensed state, which makes the operating staff have no sense of concern.
When the staff did not pay attention when they were working, they accidentally stepped on it. When the falling speed of the wire rope of the anti-dropping device exceeds 1 m/s, the runner drives the brake teeth to act, brake the runner, and the wire rope is stopped. Can't fall.
In the event of a fall, the pull-out speed of the safety rope of the fall arrester will be significantly increased. At the same time, the internal locking system of the fall arrester will automatically lock immediately, so that the pull-out distance of the safety rope does not exceed 0.2 meters. The impact force is less than 2949N, and there is no harm to the person who missed the foot.
When the load is released, it will automatically resume work. After the staff completes the work, the safety rope of the fall arrester will be automatically recovered into the device for us to carry.
The anti-dropping device has stable locking, high safety factor and good reliability, and it can effectively solve the accident caused by the staff falling and swinging excessively and hitting other objects during tilting operations.
