Ive been running a 22 Ton Grove Rt for one of my customers. I normally would nt run someone else cranes but they give me a lot of good work ,so i help them out.The machine came to the current owners from a rental co. and was well maintained ,but still a rental. Going through the fine print in the inspection documents the other day ,i find the inspection letter has a qualifying clause in it. Certification valid subject to slewing ring bolts being torqued to manufacturers specs. No mention of any checking for wear on the actual bearing.I know these bolts are fcking important, but to direct the owners to just grab a torque wrench and pull on them dosent make sense ,if you did find a loose one its probably stretched and if you moved the others at all your most likely stretching them to. Not to mention ,its no simple job to access all these bolts . If it were mine and i was asked to retorque the bolts id lean toward just replacing replace the bolts after the tolerances on the bearing it self were checked and verified good . Am i being too fussy?
