Parts Remanufacturing

Helping customers maintain productivity while reducing lifecycle costs

Hitachi Construction Machinery operates globally a business that remanufactures hydraulic pumps, hydraulic cylinders, drive equipment and other equipment as parts with performance equivalent to brand new ones.
We collect used components, disassemble, wash, repair and replace inner parts at our remanufacturing plant, and sell them as remanufactured components at around 60 to 70 percent of the price of a brand-new product.
For example, at a large overseas mine located far from the city, mining machinery continues to operate almost 24 hours a day.
When a failure occurs, it takes time to restore functionality while ordering the necessary parts for replacement.
Hitachi Construction Machinery has set up component remanufacturing plants around the world. By supplying remanufactured components from a plant that is closer to a mine, the machinery can be restored earlier, helping the customer maintain productivity and reduce lifecycle costs.
The re-use of parts and components also reduces industrial waste.
As an initiative towards building a circulating society, we will continue to promote the component remanufacturing business to ensure that remanufactured components can be supplied in a stable manner.

Revive, REMANUFACTURE once again.

40 years ago, the UH07-5 hydraulic excavator was actively operating in the market. This video shows how hydraulic components from that machine are being remanufactured today.

Previously, these old used parts had no intrinsic value and were destined only for the scrapyard. However today, Hitachi Construction Machinery’s technical capabilities, experience and know-how, allows them to restore these components back to their former glory.
