The DCR L130-F5 (maximum drilling diameter: 165mm) uses a clean engine that complies with emission regulations (EPA Tier 4 Final / EU Stage V). The Super Economy Mode PLUS cutting-edge fuel-saving technology used on the new drill allows the operator to select the engine speed during drilling operations according to rock quality, reducing fuel consumption while maintaining drilling performance. In addition, a compressor with powerful flushing capability and a high-performance dust collector provides high drilling capacity and reduced cycle time. The conventional frame and boom shape have been revised to simplify transportation and maintenance operations.
The environmentally friendly, clean engine complies with market-specific emission regulations and achieves the highest level of low-emission components with significantly reduced PM (particle compounds) and NOx (nitrogen oxides) emissions.
The iMS monitor screen allows selection of the engine speed during drilling from three levels (1600, 1800, and 2000 min-1), and by selecting the appropriate engine speed according to the rock quality, the Super Economy Mode, the most advanced fuel-saving technology, contributes to improved fuel efficiency while maintaining drilling performance. In addition, a new system with New Auto Throttle Control has been added to further reduce fuel consumption.
Equipped with a high-pressure, large-capacity air compressor with a standard discharge pressure of 2.5MPa and a standard discharge volume of 24.3m3/min (at engine speed of 1,800 min-1) and a maximum discharge pressure of 2.3MPa and a maximum discharge volume of 27.0m3/min (at engine speed of 2,000 min-1). The combination of a high-performance dust collector with a large air volume (75m3/min) and a pre-cleaner as standard equipment provides excellent drilling performance.
Powerful flushing and a high-performance dust collector significantly reduce residual cuttings and ensure shorter cycle time. The suction hood slides up and down, allowing the operator to check the collaring and to easily treat the mouth of the hole.
The rig's cab meets ROPS/FOPS specifications and outside air induction air conditioners are standard equipment to maintain a comfortable indoor environment. Its airtightness allows for comfortable work under a variety of operating conditions. A finger control switch-type travelling lever is adopted, enabling travelling operation in a natural working posture and reducing fatigue in work. While there is also a centralised display of machine operating and maintenance information on a 7in colour LCD panel (iMS Monitor). When an abnormality is detected, it is shown on the display to shorten troubleshooting time.
A semi-automatic rod changer is equipped to continuously perform a series of complex operations from addition to collection of rods by simply pulling down one-rod changer control lever in one direction. Speedy movements shorten the cycle time. In addition, the use of a rotary rack system that allows free selection of rods makes it possible to equalise rod life.
By reviewing the conventional frame and boom shape, a transport attitude height of 3,500mm was achieved without removing boom parts, which meets local market road traffic laws.
Finally, the maintenance posture of the guide shell is horizontal and its height above the ground is lowered, making maintenance of the guide shell easier than before.
