Use of round sling and hoisting method of steel pipe sling

1
Advantages of circular sling when lifting trees
The round sling has the same advantages when lifting trees, because the round sling is more close to the tree rod when connecting with trees, so that it is not easy to fall off in the lifting process
Moreover, the appearance of the flexible lifting belt is relatively soft, which can not cause damage to the big tree when bearing force
At present, the specifications and models of lifting belts used for lifting trees are: 1
5m soft sling, 1m round sling or flexible round sling

Hoisting steel pipe with round sling
It is also possible to use round polyester sling to lift steel pipes, but it should be noted that flexible sling cannot lift steel pipes with obvious edges and corners and welds, because the wear resistance of synthetic fiber round sling is poor
When lifting steel pipes with obvious edges and corners, it will accelerate the damage of protective leather belt, so as to reduce the service life of sling, In addition, if the damaged belt is not found in time during the hoisting process, the hoisting accident will be caused

Compared with the angular steel pipe, the welded steel pipe will cause greater damage to the hoisting belt, because the narrow weld has a local impact on the synthetic fiber hoisting belt during hoisting, and it is not easy to be found during hoisting
Therefore, once the weld cuts the hoisting belt, the hoisting accident is inevitable
The hoisting of steel pipes and pipelines starts from understanding the hoisting tools to avoid losses and accidents caused by lack of information
