Posted By Robert K Lewis I think strictly you have to accept the latest inspection. The original company will simply insist they were right at the time of test. It is a bit like the MOT - you cannot win the argument Bob

Posted By William Lloyds supply my workplace with insurance for the cranes and from what i know they also say how much it can lift. I would contact whoever supplies your liability insurance to find out more. The reason why you may have had different swl by different engineers could be that one noticed a defect that the other did not and decided to derate the swl to take this into account.

Posted By David A Cooper As an engineer surveyor I have to take the crane manufacturers SWL as the actual one. I wouldnt derate the crane unless I could apply some quantum that made the new SWL a guaranteed safe load. Most detected defects would render the crane out of service rather than derating. I suspect that you may have a situation where the crane is affected by something else for example if it is an overhead crane and the track has a swl then the crane swl is the track swl MINUS the crane weight etc etc...Dave
