Tensioner exhibition
1, "1 + 1 = 2": advertising cloth tensioner hook a wire rope can lift 5 tons, two wire rope can lift 10 tons, this view is extremely incorrect. As the angle of the plumb line becomes larger, the force of the wire rope will continue to increase significantly.
2, wire rope, chain is safe: some employees think that the safety factor of wire rope rigging and chain is very high, generally will not overload, even if the overload wire rope breakage and signs, but the premise of all this is in the spreader intact state. In actual use will often vary degrees of wear spreader, if the wear serious spreader may be in the lifting rated load range can suddenly break, the wire rope in the case of damage will also be no signs of fracture, so we must often check the timely scrapping.
3, single plate lifting pliers on the rated tonnage number is a load, two should be twice, this view is not entirely correct. Because the veneer lifting pliers are used in pairs, so most manufacturers tensioner price pliers on the rated tonnage number is a pair of load amount, a few manufacturers exception, so check the manual in detail before use.
