I have just been given a job to sandblast this tier Crane of steel surface area 512 sqm. though I have been in this business for 4yrs now, I see this different because I discovered some of the steel members torn at welded joint and some will too light after sandblasting. anyone with experience to suggest maintenance plan.
Best advice I can give is that if a tower crane has welded joints that are torn get off it, dismantle it, and either have it fixed and certified or junk it. It is not worth your life.
Is it a whirly all assembled and on rails kind of crane, or a dismantled tower crane that you erect on a building site kind of crane? If it's in pieces on the ground send any pieces that need repair to a certified crane repair company, or consult the manufacturer for some advice.
thanks guys, am grateful, am confident on it now.
