2. Pull back/up Capacity – 19,000 Kgf
3. Pull down Capacity – 9,500 Kgf
4. Max. Pull back/up Speed – 32 mt. /min.
5. Hydraulic Cylinder Qty. – 02 No.’s

The Feed system will be incorporated with Hold back arrangement to control and limit weight on bit, rapid and slow feed arrangement to suit the variable ground conditions.

HYDRAULIC SYSTEM:

The hydraulic system is designed for fuel efficient and high productive capacity. All hydraulic elements like Pumps, Motors, Valves, Suction filter, Return line filter and cylinders shall be of adequate capacities and of reputed makes. Variable displacement Piston pump with Proportional valves are used for Rotation and Feed (Fast and micro feed), mud pump and divert valves are used for auxiliary drives like mast raising, rig leveling, Break-out wrench, Hydraulic oil cooler etc., All hoses shall withstand to High pressure and high temperature. The hydraulic oil shall be filtered during Suction and Return lines. Max. Operating pressure – 150 kg/cm2 Hydraulic Tank capacity – 700 Lt. Filtration (Nom.) – Return line – 10/25 microns Hydraulic Oil Cooler – Fin type Oil to Air The entire Rig is designed to operate at high temperature encountered in the normal weather conditions and is robust and extremely rugged.
