In Situ Crankshaft Grinding | Onsite Services | Innovative Repairs | Bangladesh

When it comes to maintaining engine performance, the crankshaft is the most important component. Found in marine vessels, power plants, and heavy machinery, it’s a crucial part of the engine. But when it gets damaged or worn out, it can bring operations to a screeching halt, leading to expensive repairs and downtime. Traditionally, fixing a crankshaft meant removing it entirely— a process that’s time-consuming, costly, and a logistical headache. RA Power Solutions is a global leader in crankshaft repair, which has brought its revolutionary in situ crankshaft grinding technology to Bangladesh. This innovative solution is changing the game for industries across the country.

What is In Situ Crankshaft Grinding?

In simple terms, in situ crankshaft grinding is a way to repair crankshafts without taking them out of the engine. Instead of dismantling the entire machine and sending the crankshaft to a workshop, the repair is done right where the equipment is located. Using specialized portable grinding machines, technicians can restore the crankshaft’s journals (the smooth, polished surfaces that connect to other engine parts) to their original size and finish. This ensures the engine runs smoothly and extends its lifespan, all without the hassle of removal.

Why RA Power Solutions Stands Out

RA Power Solutions is a trusted name in the world of crankshaft repair, with 4 decades of experience and a reputation for excellence. The company has brought its expertise to Bangladesh, offering in situ crankshaft grinding services to industries like shipping, power generation, and manufacturing. Their team of skilled technicians uses advanced crankshaft grinding machines to deliver repairs that meet or exceed OEM (Original Equipment Manufacturer) standards. This is especially valuable in Bangladesh, where industries often face logistical challenges and need quick, cost-effective solutions to keep operations running.

The Benefits of In Situ Crankshaft Grinding:

Less Downtime, More Productivity:

Since the crankshaft doesn’t need to be removed, repairs are completed much faster. This means less downtime for businesses and more time for productivity.

Precision Repairs:

RA Power Solutions uses cutting-edge technology to ensure the crankshaft is restored to its original specifications. This precision ensures the engine performs at its best and lasts longer.

On-Site Convenience:

Whether it’s a remote power plant or a ship docked at a port. RA Power Solutions can bring its portable grinding machines to the site. This flexibility is a huge advantage for industries in hard-to-reach locations.

One standout example of RA Power Solutions’ impact in Bangladesh is their work with a major power plant. The plant’s crankshaft had worn down over the years of use, threatening to shut down power generation. Instead of going through the lengthy and expensive process of removing the crankshaft. RA Power Solutions’ team performed in situ grinding onsite. They restored the crankshaft to its original condition, ensuring the plant could continue operating without interruption. This not only saved the plant from costly downtime but also demonstrated the effectiveness of in situ grinding in real-world scenarios.

As industries in Bangladesh continue to grow, the demand for efficient and reliable maintenance solutions is on the rise. In situ crankshaft grinding is perfectly positioned to meet this demand. RA Power Solutions, with its advanced technology and experienced team, is leading the charge. By adopting this innovative technique, businesses in Bangladesh can reduce repair costs, minimize downtime, and keep their operations running smoothly.

Crankshaft Repair | Grinding of Crankshaft | Crankshaft Machining – RA Power Solutions

RA Power Solutions has been working on high-capacity diesel engine overhaul, repair, and maintenance, and grinding of crankshafts for the last 45 years. During our work on engines on board a vessel or in large engineering plants, we have observed that the incidents of crankshafts getting damaged due to accidents are becoming increasingly often.

As we are aware that the crankshaft is the heart of the engine. Using the connecting rod, the crankshaft converts reciprocating motion to linear movement, which drives the engine. RA Power Solutions has the process, technology, and onsite crankshaft grinding machines ranging from 35 mm to 700 mm, and crankshaft repair is now possible without disassembly of the crankshaft from the engine. The repair of the crankshaft is possible irrespective of its length and weight, as we have the equipment available up to 700 mm in terms of diameter.

The crankshaft, in general, has various applications, including diesel generating sets and marine engines. Typical areas of crankshaft applications are as follows:

Compressors
Railway vehicles/engines
Power generators
Forging hammers
Pumps
Marine engines, etc.

The crankshafts of high-capacity engines used for marine and land-based applications are of forged steel. RA Power Solutions has experienced technicians and advanced technology equipment, i.e., an in situ crankshaft grinding machine. To maintain the dimensions and tolerances strictly as per the manufacturer’s specifications and recommendations.

Major parameters maintained after crankshaft grinding and repair and grinding of the crankshaft, are as follows:

Taper and ovality can be maintained within 0.02/0.03 mm or less as per the requirement of the engine manufacturer.
The portable in situ crankshaft grinding machine used by RA Power Solutions. The technicians are capable of maintaining a surface finish of far less than 0.03 RA value.
The high surface finish achieved after grinding the crankpin and main journal diameters significantly improves performance. It enhances the life of the connecting rod and main bearings.

Inspection of Crankpin Before Repair & Grinding

The radius profile of both the end of the crankpin or main journal and the lubricating oil profile is maintained strictly as per the original profile.
The straightness/runout of the crankshaft is checked, and the crankshaft is straightened if required by the peening process.
Counterweight can be replaced in case of damage, and supporting threads are repaired onsite.

During our work of more than four decades, we have repaired more than 10,000 crankshafts used for different applications. All the repairs are executed with a guarantee. We are an ISO-certified company and also meet the standards requirements like DNB, Lloyd’s, etc. All our technicians possess Indian CDC and can join the vessel in a short time in any part of the world.

Crankshaft grinding and repair are essential processes in the field of engine maintenance and precision engineering.
