Trost came to us because several parts of their crane were writhed due to an unknown reason. A possible cause is that the jib tipped over when the boom was fully extended, or that it remained hanging at a perpendicular angle. Trost looked for a repair service that was qualitatively outstanding yet more cost-efficient than simply turning to the manufacturer to buy completely new parts.
Boom reparation 2x new upper hood, calibration, 2x torsion cancellation
Boom parts T1 and T2 suffered minimal torsion and could be calibrated as such. This type of calibration is not a simple task, seeing as the steel type St 960 has a very high maximum yield point. Thanks to the expertise that Rusch has at its disposal, we still succeeded in completing this task. For the client, this resulted in a solution that is both cost-efficient and carries a quality assurance by Rusch.
With 2 other boom parts, T3 and T4 respectively, the upper hoods were writhed to such an extent that it was necessary for us to divide these parts. We were able to re-use the lower hood parts by means of calibration. We replaced the 2 upper hoods and welded them back onto the lower hoods. We were able to spare the front and back axles, after which we could also re-use the lockout gates and weld them back on.
