C5A Core Drilling Rig

 FORWARD’S new C5 we named C5A 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 C5A has been built with reliability in mind and is assembled using only the very best first-world components such as Sauer Danfoss pumps and PVG valves, Danfoss and Eaton hydraulic motors, Manuli Hoses and Cummins engines.
 
The C5A is extremely compact but has depth capabilities that are only found on much larger rigs. AND, it drives straight into a shipping container which makes it extremely economical to ship anywhere in the world.
 
With safety in mind, the C5A 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 2 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 slides off 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
  • When the rig is shutdown or being transported the Control Panel can be locked to prevent damage or vandalism.
  • Both the Rotation and Fine Feed controls are fitted with friction dampeners with positive and easy to find neutral positions.
  • There is an auto alarm function for low level of hydraulic oil.
  • 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 metres 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.
