Tensioner exhibition

1, "1+1=2" : advertising burler lifting hook of a wire rope can lift 5 tons, two wire rope can lift 10 tons, this view is not correct.With the increase of the Angle of plumb line, the stress of wire rope will increase greatly.

2, wire rope, chain is safe: some employees think the safety factor of wire rope and chain is very high, generally not overload, even if overload wire rope break there are signs, but the premise of all this is in the sling intact state.In the actual use of different degrees of wear and tear sling, if the serious wear and tear of the crane may be in the scope of rated load can suddenly break, wire rope in the case of damage will also be no sign of fracture, so it is necessary to frequently check timely scrap.

3, the rated tonnage on the veneer lifting pliers is the load of one, two should be twice, this view is not entirely correct.Since single plate lifting pliers are used in pairs, the rated tonnage on the tensioner price pliers of most manufacturers is a load of a pair, with a few exceptions, so please check the manual carefully before use.
