Excavator is the equipment used to dig, move & handle earth on a large scale. These are widely used in the mining industry. They are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform (known as the "house"). The house sits atop an undercarriage with tracks or wheels.
The losses resulting from the defect or breakdown of equipment amount to incredible sums, often far higher than the cost of maintenance, repair or reclamation. It is for this reason that mining industries have to take preventive and periodic maintenance of the equipment.
We understand the importance of the breakdown of running equipment and hence offer in situ job repair by our expert technicians to minimise lead time and also assure job to be completed within stipulated time.

In mining, Earthmoving equipment has to handle all the mineral ores of all different shapes and sizes. The wear factors are not always the same. There are a few excavators which handle rocks/boulders (limestone) whereas there are a few that handle minerals in disintegrated form (iron ore/latterite). In the case of limestone, the bucket will lose its life due to impact & gouging abrasion when the limestone is scooped out of the surface. Whereas, in the case of the latterite, the bucket loses its life because of impact and scratching abrasion. These types of wear factors are the most common in buckets.
We can overcome the wear caused by impact, gouging abrasion and scratching abrasion, if the base material is induced with evenly distributed primary, secondary & tertiary carbides in the matrix. The even distribution of the larger chromium carbides along with eutectic carbides & martensite in austenite provides the answer to the problem. These carbides avoid wear by avoiding the contact of the abrasive media with the softer austenite as the wear of the carbides is very low compared to austenite. Meanwhile, austenite has shock absorption ability. Hence this formation increases the operating life.
In our EWAC product range – EDP 600 is the ideal solution to overcome this problem. It has the following features:
Saving :
Based on the performed calculations and experience of mining personnel, it has been observed that in terms of economy, reclamation of an excavator bucket is more cost-effective than purchasing a new one and it is around less than 50% of the actual price of the original one.
Our unique relationship within the mining industry has been established over many years. Eutectic's engineers have developed a comprehensive understanding of specialized problems experienced within the industry. We aim to provide the most practical and cost-effective solution.
