74 E&MJ; • OCTOBER 2017 www.e-mj.com EQUIPMENT GALLERY Caterpillar announced its new MD6310 rotary blasthole drill enables effi cien- cy and productivity improvements. Cat electronics deliver advanced trouble- shooting for effi cient drill operation and scalable automation, the company reported. The building blocks include drill assist, semiautonomous and re- mote-control operation, and machine health reporting. Ideal for 12-meter (m) and 15-m bench heights, the rig is ap- plication-built for effi cient single-pass drilling down to 13.7 m (44.9 ft) or 17.5 m (57.4 ft), depending on mast confi gu- ration. It offers up to 30° angle holes for cast blasting. Reaching deeper hole depths than predecessor Cat rigs, the MD6310 better matches specifi c drill and blast require- ments when working with electric rope shovels or other loading tools that require a tall and steep muck pile, the compa- ny reported. Standard on the rig is a drill depth indicator, auto-level/retract and au- to-mast. The rig drills up to 311-millimeter (mm) hole diameters. When equipped with the 13.7-m mast, it delivers up to 289.13 kilonewtons (kN) pull-down and hoist capacity to drill hole depths reaching 62.5 m. The 17.5-m mast delivers up to 382.5 kN pull-down and hoist capacity for drilling hole depths down to 48 m. The rig is powered by a Cat C32 ACERT Tier 4 Final engine that produces 760 kilowatts (kW) at 1,800 rpm, or a Tier 2 equivalent engine producing 770 kW at 1,800 rpm. Its compressors feature variable air control that can be adjusted to 50% less volume to meet application requirements. Water injection with tank capacity of 1,514 liters is standard on the MD6310 and is integral to Drill Assist for collaring the hole and dust suppres- sion. A high-volume water injection sys- tem is available with additional tank. www.cat.com Filter Kits for Mobile Equipment Kolberg-Pioneer Inc. (KPI) has new fi lter kits for all of its equipment that improve engine performance in dusty environments. The fi lter kits cover all access doors and openings. They can be easily retrofi tted to any model. The fi lter media is replaceable using a simple retention system with posi- tive locking pins and clips. The media can also be purchased in bulk. www.kpijci.com New Rotary Blasthole Drill
