The sewer cleaning work is a very complex project. Workers need to use rescue tripods to move into the sewer to carry out the cleaning operation. The operation steps are as follows:First, adjust the height of the support to ensure the stability of the tripod. Then, install the rope winch and pulley, connect the anti-fall device, and wear a well-fitting safety belt. After connecting the hook of the safety belt to the safety hook of the winch and the anti-fall device, you can start working.
Some work sites are very complex, so the workers need to maintain sufficient physical strength to escape in time when encountering unexpected problems.
