In Vimpeli, Maansiirto Mika Pyhälahti Oy is pleased with the delivered Robi EH300E hydraulic breaker. In demanding applications, attachments must also be of the highest quality, especially when the company operates across a wide geographical area with a versatile transport fleet. The CAT excavators operated by Maansiirto Mika Pyhälahti most commonly work at crushing plants, where the hard Finnish rock puts both the machines and attachments to a demanding test.
“I have been working in the industry for more than 30 years, so I have gained extensive experience with different hydraulic breaker brands and models. When it was time to purchase a new breaker, I contacted Ramtec’s sales representative Juhani Rannikko. We quickly found a product that suited our requirements. The Robi EH300E met our technical requirements precisely, and the purchase process was easy and straightforward,” says Mika Pyhälahti.
“The breaker arrived in early summer, and after the initial adjustments, the unit has operated flawlessly without any teething problems. Considering its power, the lightweight breaker has already worked for more than 400 hours at the end of the CAT 336 excavator boom. Our contracts, which often involve working two shifts, have put the Robi to a demanding test. Feedback from our operators has consistently been that the Robi delivers powerful yet smooth impacts. This combination is difficult to achieve, as I have tested other brands over the years. The smooth impact is naturally comfortable for our operators working long shifts, and at the same time, this feature is sure to contribute to the durability of the excavator itself.”
Regular maintenance keeps the jobsite running.
“Our company has always placed a strong emphasis on regular and high-quality maintenance, and the Robi is no exception. When needed, our own maintenance operations are complemented by Ramtec’s professional after-sales services. For example, based on our positive experiences with spare parts and maintenance services, we have strong confidence in Ramtec’s operations. This ensures a long service life for the breaker, even in demanding applications,” Pyhälahti emphasizes.
ROBI EH300E is a powerful and user-friendly hydraulic breaker
- Powerful and consistent impact energy – The Robi EH300E’s fixed impact energy ensures that every blow is equally powerful. Consistent quality is one of Ramtec’s fundamental service commitments.
- Smoother operation and effective vibration damping – The slim and durable housing combined with effective vibration damping reduces stress on both the breaker and the excavator boom. In Maansiirto Mika Pyhälahti’s practical experience, the combination of powerful yet smooth impacts has received particular praise.
- Long service life and easy maintenance – The breaker’s construction, lubrication and serviceability are designed to extend its service life and reduce total operating costs. High-quality manufacturing together with our after-sales service ensures that the breaker remains in operation for a long time.
Ramtec’s Juhani Rannikko, who sold the Robi EH300E breaker to Pyhälahti, is pleased with the feedback received.
“Information from professionals is invaluable to us, and we carefully consider their feedback when developing our products. The Robi EH300E is a good example of this: for instance, the durability of its bottom plate has been improved based on customer requests, while we have also invested in the breaker’s wear resistance and damping. When Pyhälahti purchased the breaker, they knew exactly what they required from the product, and it is great to hear that the Robi has met the expectations of experienced professionals in the industry,” Rannikko concludes.
