Product Description

FORWARD C4 CORING DRILL RIG


FORWARD'S C4 is a compact crawler mounted rig with all the user-friendly functions drillers are looking for and all at their fingertips. The rigs are built under strict quality control protocols and are rigorously tested before dispatch.
 
The C4 has been built with reliability in mind and is assembled using only the very best first-world components such as Rexroth pumps and HAVE valves, Rexroth and Eaton hydraulic motors, Manuli Hoses and Cummin engines.

The C4 has the 4 speeds gear box provides free combination of torque and rotation speed.

The C4 equipped PQ chuck and 3500 mm stroke of rotation facilitates handling of rods of 3 meters length.

The wonderful convenience of control of feeding pressure, Real time reading of drilling data on gauges on the control panel. Mud pump and mixer powered by the rig's hydraulic system, controlled directly on the rig's panel

With safety in mind, the C4 has all the features that you'd expect in a modern rig such as safety guards and emergency stop buttons on all corners of the rig, fire extinguishers and optional automatic Co2 fire suppression.

ROTATION HEAD

• The 4 Speed Rotation Head can accept all sizes of coring rods up to PQ.
• Patented chuck jaws and hydraulic opening/spring close function insures a fail-safe operation.
• The Rotation Head is connected direct to the hydraulic feed cylinder which simplifies the whole mast design and minimizes maintenance.
• The Rotation Head also rotate to the side and opens the whole mast up to run casing or pull tubes etc.  

MAST

• The Rigid design of the mast provides superior performance and reliability even under the toughest geological conditions.
• The set-up controls are mounted at the side of the rig and can be isolated from the circuit during drilling operations.
• The Mast raise cylinders are equipped with balancing valves to increase safety.
• The folding mast allows the rig to be transported on short trailers or in a shipping container.
• The Dump Mast reaches the ground at angles up to 45degrees and ensures all the pullback forces are absorbed by the ground and not the rig.

CONTROL PANEL

• Both the Rotation and Fine Feed controls are fitted with friction dampeners with positive and easy to find neutral positions.

 

• All the gauges are conveniently located for ease of monitoring.

HOOD:
The steel hood provides adequate protection from the elements yet opens up for ease of
maintenance.

HYDRAULIC SYSTEM:
All the hydraulic pumps are genuine Variable Displacement, Pressure Compensated, Load Sensed Sauer Danfoss Piston pumps.     

MAIN HAUL WINCH:
The Haul Winch is securely mounted central to the rig chassis.

WIRELINE WINCH:
The Wireline Winch has auto spooling and 1500 meters capacity.
 
CRAWLER CHASSIS:
The Crawler chassis is manufactured in house and has quality Korean sourced hydraulic drive motors.

MUD PUMP:
The 1000psi mud pump is conveniently located at the front of the rig for ease of maintenance but high enough to allow a descent angle of attack when traversing creek beds
