The mast is approximately 15-3/4 ft(4.5m) from the bottom of the slide base. The mast is pivoted on the drill frame, permitting separation of the drill with the mast horizontal. Quick mast disconnect is standard. Sheaves are provided for the cathead rope and the winch cable.
The cathead is hydraulically driven from the drill rig hydraulic system. The cathead drum is 6″ (152mm) in diameter.
- Line Pull : 1000 lb. (454 kg)
- Speed : 415 ft/min (126m/min)
The hydraulic hoist utilizes a worm gear drive with a sealed case. Gears and tapered roller bearings run in oil. Housing and drum are designed to prevent fouling of the cable. Hoist is provided with a safety brake to prevent roll back.
A hydraulically operated sliding base provides 16 inches (406mm) of travel to provide clearance for hoisting tools. The sliding base can be mounted on any flat surface of adequate size.
Hydraulic jacks are available for rear and front mounting.
Double axle trailers are available for transporting and drilling with the rig. Steel ramps are provided for removing the rig from the trailer.
Welded steel water tanks mount at the front of the truck rig drill platform. Track rigs do not come with optional water tanks.
Dimensions vary with the truck or carrier size. Welded construction consists of structural steel and deck plates. Running lights are included.
Standard D-25 truck rigs require a minimum of an F-550, Chevy 5500, or larger. Options may be limited dependent on truck provided.
Above deck rod rack and underbody rod rack are standard with drill platform. Optional rod storage under the water tank is also available.
Above deck auger rack is standard with drill platform. Underbody fixed or hinged auger racks are available.
Tool boxes are available for above or below deck mounting in several sizes.
Pump is frame mounted and driven from the rig hydraulic system.
- Moyno 3L4 or 3L6 with variable speed
The feed frame sheave mount bolts to the top of the feed frame to allow use of the cathead and winch when drilling with the mast horizontal. This permits drilling in 10 ft (3m) overhead clearances with a skid mounted rig.
The drill can be mounted on a steel skid with an overall length of 116″(2946mm) and a width of 48″(1219mm). The arms of the skid are removable for ease of drilling and maneuvering.
Skid rigs are available with an integrated winch mounted to the front of the frame. This allows for self-maneuvering the rig using an anchor point.
Casters clamp to the skid frame for ease of movement on hard surfaces.
