The DG700 was supplied by MSPM, Sandvik Construction's authorised distributor in Myanmar, and has been put to work to boost the quarry's productivity in order to meet rising demand for high-quality aggregates.

Long Life Aggregate Mining is a long-standing Sandvik Construction customer, which currently operates a range of Sandvik crushers and screening equipment, including a CJ613 jaw crusher, CS440 screen and two CH440 cone crushers.

MSPM assisted Long Life Aggregate in choosing the right surface drill rig. The distributor identified that the company required a hydraulic, self-propelled, self-contained, crawler-based rig, which could be easily maintained. The rig would need to offer substantial power and strength in order to provide good performance.

According to Sandvik, the Tiger DG700, which features a robust structure, a low centre of gravity and heavy-duty tracks with an efficient guide system, offers good stability and balance, even in uneven terrain, making it suitable for operations in countries such as Myanmar.

It is also equipped with a fixed boom, an efficient rod-handling system and Sandvik rock drills. In addition, the rock-drilling control system guarantees smooth collaring, thereby improving the rock tools' service life, delivering better hole quality and improved blasting results, Sandvik stated.

The DG700 is equipped with a 179kW Tier 2 engine with a large fuel tank of 425L, helping maximise drilling time. All its maintenance points are on the ground level, and components are placed within easy reach. This was an important consideration in the choice of the drill rig, as daily maintenance will be undertaken at the quarry
