The remanufacturing cycle
"Revive, REMANUFACTURE once again."
This project involves the remanufacturing of hydraulic parts for the UH07-5 hydraulic excavator, which was widely used 40 years ago. Although the parts were unprecedentedly old, Hitachi Construction Machinery was able to draw on its technological capabilities as a manufacturer, as well as its previous experience and expertise, to remanufacture parts that were on the verge of being scrapped and restore them to the condition they were in when they were in use.
Collection of used parts
We collect used parts previously installed in our customers' machinery. Please approach the dealer where you purchased the unit for more information on how to return the parts.
Collected parts are transported to our Group's plant for remanufacturing.
Cleaning/disassembly
Each part is cleaned carefully to remove grease and other contaminants.
Bolts and nuts are then removed from the component before it is disassembled into smaller parts.
Evaluation of reusability & repair/assembly
Our technical staff is constantly working to improve the accuracy of the evaluation criteria used to determine whether a parts can be reused so that our customers can continue to use our products with peace of mind. We are also developing processing and repair techniques that allow parts that are worn out or have minor cracks caused by prolonged use to be reused as much as possible.
Inspection/performance testing
We conduct inspections using our state-of-the-art equipment to ensure that the remanufactured parts meets the same standards as a new parts.
Painting/shipping
Parts that pass our performance testing are painted before they are shipped.
