A rock-crushing contractor in Finland has taken advantage of a remanufactured components programme for the replacement of a key component on a brand of excavators, the Hitachi ZX470LCH-5. Kone-Kostamo Oy only operates one brand of excavator, as it prefers to maintain and service its own fleet of construction machinery, and views the compatibility of parts between the different models as a priority.
The Salo-based company works with the Finnish Hitachi dealer, Rotator Oy.
The excavators are given a major refurb every 10,000 hours. When a main pump was needed for the ZX470LCH-5, Kone-Kostamo’s Workshop Manager asked Rotator for a quotation. They were given the option of using a Hitachi remanufactured component, which was in stock and able to be supplied and fitted to the machine within two days.
Alternative to refurb
“We didn’t have any spare pumps for this model, so buying the remanufactured part from the Hitachi dealer was faster than refurbing the part ourselves,” says Kone-Kostamo’s Foreman, Karri Mäenpää. “This meant that we saved ourselves up to three weeks of downtime, which is vital when you need the machine every day to load the crusher.
“We work well with Rotator and this is a good example of how happy we are with their solutions. It was an easy process: they collected the original ‘core’ component, which needs to be sent off and renewed by Hitachi, at the same time as delivering the Remanufactured pump.
“We would choose to buy a Hitachi Remanufactured part again, especially as it is environmentally friendly, in that we’re helping to extend the life of the part. The peace of mind that comes with having a one-year warranty for the pump is also a bonus. In addition, it was supplied at a good price and the machine was working again with minimal delay!”
As a contractor working for Kiertomaa Oy – the owner of the Saramäki quarry, near Turku in south-west Finland – Kone-Kostamo’s large Hitachi excavator must retain high levels of availability and productivity. This highlights the importance of getting the machine back to work as quickly as possible.
“The situation here is typical of the Finnish market,” said Karri. “Kiertomaa can be flexible, and don’t have to worry about owning and maintaining the machinery. It’s easier for them to concentrate on selling and delivering the materials to road construction sites and asphalt factories.”
Kone-Kostamo was founded in 1956. After entering this sector of the aggregates industry in 1964, it is now one of the most experienced rock-crushing contractors in Finland, employing up to 45 personnel depending on the season.
