About Atlas Copco


PT United Tractors Semen Gresik (UTSG), a joint venture between PT. Semen Gresik (Perse-ro) Tbk and PT. United Tractors Tbk, was incepted as a mine contracting company in October 15, 1992. A specialist in limestone and heavy equipment rental, UTSG is an ISO 9001 and ISO 14001 certified company has won awards as an Astra Friendly Company and Astra Green Company.

For more than a decade, UTSG has been able to keep its fleet of four Atlas Copco ROC F7 surface rigs in good condition, thanks to the service contract with Atlas Copco. A green flag flying over the cab of these rigs signals that it is in proper working condition.

Advantages of Service Agreement

According to Sri Haryanto, Managing Supervisor for the Maintenance Department at UTSG, the company’s target is physical availability. It requires 85% availability for the transportation unit and 87.5% for heavy equipment.

Eleven years ago, UTSG made the decision to contract maintenance work to drill specialists at Atlas Copco. However, it continues maintenance service on its other machines such as excavation equipment and trucks.

Service Technician Slamet Nahdudin from Atlas Copco has been involved in the maintenance of the UTSG’s fleet since 1999. Nahdudin has years of preventative maintenance experience on drill rigs. His expertise is demonstrated by 90% availability for UTSG’s fleet of ROC F7 drill rigs.

Nahdudin credited the quality of the rig, saying maintenance for the most part is a matter of changing the necessary fluids whenever required and conducting audits according to schedule. This has minimized breakdowns and keeps the rigs running smoothly.

Quarrying activity at UTSG’s facility is steady at two shifts per day, seven days a week. 

The mine maintains a 6 m to 9 m bench and exercises 2.75 m spacing and 2.75 m burden. Each drill rig is expected to drill 480 m per day using Atlas Copco Secoroc 3.5 inch bits.  

In this soft rock formation, the service life of each bit is roughly six months, averaging 72,000 meters per bit. The quarry’s current working area is 797,44 hectares and operates at an 80 m depth to sea level.


According to Haryanto, Managing Supervisor for Maintenance, the high rate of availability is attributable to the good relationship with Atlas Copco through good communication. The interaction between Atlas Copco, the maintenance department, and the logistics department are the key components of that relationship.
