Crawler Mounted Drill Rig JRD Model CD-360 DTH drilling Rig Hydraulically operated capable of handling 3 mtrs. (10ft) Drill pipe with following Technical specification.
MAST & BOOM :
Sturdy structural Channel Type Mast reinforced with suitable cross members strong enough to withstand high drilling loads. The Boom is provided with a heavy duty lift and swing cylinders to provide rigidity while drilling. The Boom lift , Boom Swing ,Guide Tilt, Guide swivel and Guide Dump arrangements are through hydraulic double acting cylinders allows the operator to achieve a wide range of vertical, horizontal and angle drilling positions.
HYDRAULIC SYSTEM :
The hydraulic system is designed for fuel efficient and high productive capacity. All hydraulic elements like Pumps, Motors, Valves and hydraulic cylinders are adequate capacity and of reputed make.
Variable displacement Hydraulic Pump with proportional Control Valve (PVG 32 Make: Sauer Danfoss) are used for Rotation Unit, Feed Unit (for fast & micro feeding) and for Self Propulsion of the Rig. All hoses can withstand high pressure and high temperature. The Hydraulic oil is fine filtered during suction and return lines in operation.
HYDRAULIC POWER PACK :
Hydraulic Power pack is driven by Diesel Engine water cooled with Power 33H.P @1500 RPM to drive one main Hydraulic Pump.
