Blasthole drilling isnt easy workfor man or machine. It requires strength, resilience and drilling smarts to adapt to ever-changing rock conditions. Terex Reedrill ensures you get the job done efficiently with the SK-L Rotary Blasthole Drill. Everything about the SK-L was designed with high efficiency and high productivity in mind. The SK-Ls robust frame and mast design; unique pulldown and hoist system; ergonomic cab; and conveniently located and service-friendly heavy-duty components make the SK-L built to drill.

Pulldown and hoistThe SK-Ls unique cable pulldown and hoist system incorporates a single, double-acting feed cylinder complete with cable auto-tensioner. With up to 110,000 lbs (49,895 kg) of pulldown force, the SK-L is a valuable partner in hard rock drilling applications. The SK-Ls 86,000 lbs (39,010 kg) of available hoist force further add to its value, especially when pulling out of a hole in fractured ground with possible collapsing boreholes or in multi-pass and angle drilling operations where sidewall friction can be problematic.

Drill deeperThe SK-L is equipped with a strutless mast for 65.7 ft (20 m) single-pass hole depth. What does this mean for you? Reduced cycle times between holes and moving parts that are kept to a minimum, leading to lower operating costs. Designed to drill up to 15 in (381 cm) diameter holes in hard or soft rock formations, the SK-L achieves a maximum hole depth of 215 ft (65 m) with the long mast configuration.

For even deeper reach, an optional 54 ft (16.5 m) single-pass mast configuration is capable of producing a maximum hole depth of 279 ft (85 m).

Pipe handlingAll Terex Reedrill rotary blasthole drills are manufactured with a patented Hydraulically Operated Break Out wrench (HOBO), which is designed to increase drill productivity. From the convenience of the cab, the operator can break joints simply and safely with the hands-free wrench. The SK-L has taken this proven design and enhanced it with a variable grip that handles a range of different pipe ODs without re-tooling.

More uptime = more profitsThe SK-L is designed for field serviceability. Easy access to filters and dipsticks, as well as lubricant fill and drain points, makes scheduled maintenance quick and efficient. That equates to more up-time. The SK-Ls new A-frame design features an in-board mast-mounting arrangement with a completely bolt-on pivot shaft that makes

servicing a breeze. The SK-L is configured with Mesabi Coolers with replaceable cores, making the machine even more service-friendly. The SK-Ls auto-cable tensioning system keeps cables tight for long life, and its on-board drill-health monitoring system ensures timely preventative maintenance before minor faults develop into major failures.

a room with a viewWithin the walls of the SK-Ls 47.5 ft2 (4.4 m2), FOPS-certified cab are smartly designed features to improve operator comfort, efficiency and productivity. A full-length drill window with a broad view of the drill deck, and a roof window with a clear view of the top of the carousel and rotary head, help the operator accurately and quickly perform drilling functions.

Other cab features that increase productivity include:

Ergonomically designed split console

Backlit panels and gauges

Touch-screen drill monitoring

On-board monitoring of drill performance and drill-health

Programmable logic for a fully integrated electronic/hydraulic control system

Quiet environment, down to 72 dBa

getting thereThe SK-Ls superior maneuverability is provided by a crawler-mounted, excavator-type undercarriage, designed and built to Terex Reedrill specifications. A three-point oscillating suspension allows the drill to negotiate rugged, uneven terrain without transferring excessive torsional forces to the main frame. It also allows continued stability while tramming between holes.
