D50KS blasthole drill

The Sandvik D50KS is a diesel powered, self-propelled crawler mounted blasthole drill for mining. It is a powerful mid-range production drill and comes with a low pressure air compressor for rotary drilling. Its normal range is 152 to 229 mm (6" to 9") diameter holes, but it can optionally drill up to 251 mm (9 7/8") hole size. Maximum hole depth is 45 m (148') with 7"

drill pipe. First pass capability is 8,7 m (28' 6"). The maximum pulldown is 222 kN (50 000 lb) and bit load 267 kN (60 000 lb). Thanks to its heavy duty hydraulic system, the D50KS delivers the rotary horse power for maximum productivity throughout its hole size range.
