Lifting performance is good or bad all depends on its lifting capacity, not lifting the more heavy his performance is better, and in the use of the process of failure, what kind of goods use what kind of chain electric hoist, not overqualified, not small material.
1 some electric hoist in order to sell the use of imported famous brand products, each product has a sign, above the production of TWO-DIMENSIONAL code, can scan the two-dimensional code to identify the authenticity.
2 ring chain electric hoist has a variety of tonnage, according to their own product characteristics and weight, choose the appropriate ring chain electric hoist, do not waste, not to overload.
3 electric hoist has a certain strength, under the load is not destroyed. With a certain stiffness, there is enough resistance to deformation, under the load, its deformation (elongation, compression or bending, etc.) can be kept within the allowed range.
4. It is required to have enough ability to maintain the original shape balance, that is, it should have a certain stability.
