Crankshaft Repair on Vessel of Auxiliary Engine | Small Diameter
RA Power Solutions have been extending onsite crankshaft grinding services all over the world for the last forty-three years. Our Present capacity is up to 700 mm diameter.
We have observed that the shipping companies having Auxiliary engines installed on their vessels are facing serious problems in case there is damage to the crankshaft. The companies extending the onsite crankshaft repair services based in Europe, USA, UAE, etc do not have the equipment which is compact and portable enough to undertake the grinding of crankshaft having small diameter and small bearing width.
In this situation, the leading crankshaft repair companies ask clients to remove the crankshaft from the engine block and send it to the workshop. In some cases, they even reject the crankshaft to save themselves from embarrassment.
