Different working levels of cranes result in structural differences
Thread Content
Taking a 50T bridge crane as an example, when the service classes are set at A3 and A5 respectively (with all other technical parameters remaining the same), what are the main differences between the two cranes? Is there a big difference in cost? Suppose the procurement requirement is A5, but the crane manufacturer produces and supplies it according to A3. How can this be identified?
Are there no experts in manufacturing or cranes?
