Tractor Mounted Drill
Technical Features
KALA KTM-130
Tractor mounted Rigs are specially designed for fast & cost effective drilling, economical alternative to crawler mounted drill. The drill is capable of drilling 102-115 mm dia holes up to a depth of 130 feet in Blast hole drilling using down the hole Hammer and bits.
MAST
Heavy duty drilling mast fabricated out of robust welded sections & designed for vibration free and continuous duty conditions.
Rotary Head
Piston type air motor with spur type heavy duty gear box
Feed Unit
Piston type air motor with spur-cum-worm type gear box
STABILISER
During drilling, entire load of the unit is shifted on to three hydraulic jacks provided. Desired set up of the unit is achieved by individual/separate leveling control through hydraulic directional control valves guided by a spirit level indicator to obtain desired setup in rough terrain. Additional Double check valve is incorporated in the hydraulic system as extra safety measures.
HYDRAULIC SYSTEM
The source of power is drawn from Tractor prime mover to operate hydraulic pump of adequate capacity for actuating hydraulic stabilizers, raising/lowering of mast.
OPTIONAL SPECIAL TROLLEY
If desired, a double axled special trolley (with articulate front axle) can be manufactured & supplied by us at extra cost to conveniently house compressor, diesel tank for entire unit, drill tubes and other accessories and allied items, which can be towed by the KTM-130 Tractor Mounted Drill
