RA Power Solutions has more than four decades of experience in providing in situ crankshaft grinding, in situ crankshaft inspection and in situ grinding crankpins, and repair of the crankshaft of large high-capacity marine engines or engines installed for various applications.
In olden times whenever the crankpin or main journal of the crankshaft was damaged due to bearing failure or any other reason, the crankshaft was removed from the engine block by disassembly of the complete engine, packed, and taken to the workshop for grinding on a stationary crankshaft grinding machine.
This exercise not only delayed the commissioning of the engine but also cost it a fortune. In the early 80s, we received many crankshafts in our plant from overseas including Qatar, South America, etc. weighing more than 9 tons by Sea/Air.
With the introduction of an onsite machining tool, it is possible to undertake the repair of the crankpin and main journal. RA Power Solutions undertakes onsite grinding of crankshaft and main journal of the diameter ranging from 35 mm to 700 mm. The repair is possible without disassembling the engine and there is no need for the removal of the crankshaft. The portable and lightweight crankshaft machining tool is inserted from the window for grinding and polishing.
The onsite crankshaft grinding machine design used by us is of the latest design and is a technological revolution. It is centerless equipment and works on the same concept as of bench-type crankshaft grinding machine. No reference to the radius fillet of the crankpin is taken as in case of an accident the radius fillet gets damaged.
