Hydraulic System

On the D-50 unit, oil is supplied by a heavy-duty gear type two-section pump rated at 19 GPM (72 L/min) and 24 GPM (91 L/min) at 2400 RPM.  Maximum operating pressure is 2300 PSI (15,513 k Pa).  The pump is gear driven from the engine accessory drive.

Hydraulic valves are stock sectional body directional control valves with relief.  An optional regenerative spool can be provided for the main feed valve providing a high-speed spindle lift as well as normal operation.  All controls are conveniently located on a single console for ease of operation.

Auger Adapter

A heavy duty universal joint which mounts to the spindle with a single nut is provided for ease in hook-up and adjusting for misalignment.  All components are sized to withstand torque and axial loads encountered under most drilling conditions.  1-5/8” (41.3 mm) female hex is standard, other sizes are available.

Mast

The mast is available in 2 standard lengths for 15 ft(4.6m), and 20 Ft(6.1m) pulls. The maximum mast height is limited by the type of carrier. The mast is pivoted on the drill frame permitting operation of the drill with the mast horizontal. Quick disconnect is standard for both lengths. Sheaves are provided for 1″(25.4mm) manilla rope, 3/8″(9.5mm) and 1/2″(12.7mm) wire rope. The sheaves are 8″(203mm) diameter to reduce fatigue in the wire rope.

Cathead

The cathead is mechanically driven from the drill transmission. The PTO provides 1 speed forward and 1 reverse. Drum is 8″(203mm) diameter and 6″(152mm) long with generously sized anti-four flanges.

  • Line Pull : 5,000#(2270 kg)+
  • Speed : 500 ft/min (153m/min)+

The cathead is mounted to the right rear of the drill and is perpendicular to the long axis of the drill frame.

Hydraulic Hoist

Various capacity options are available. Hydraulic hoists utilize 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. The controls are mounted on the operators console. Hoists are provided with a safety brake to prevent roll-back.

Slide Base

A hydraulically operated sliding base provides 16 in(406mm) of travel to provide clearance for hoisting tools. The sliding base can be mounted on any flat surface of adequate size.

Leveling Jacks

Jacks are available for rear and front mounting. 4″(102mm) bore cylinders are enclosed within telescoping steel tubes for increased durability and stability. Each jack is provided with a pivoted foot pad with a non-slip surface. Standard stroke is 36″(915mm)

Trailer Assembly

Double axle trailers are available in 6000 lb. (2720 kg) and 9000 lb. (4080 kg) capacities for transporting and drilling with the rig. Steel ramps are provided for removing the rig from the trailer.

Water Tank

250 gallon (946 l) or 500 gallon (1892 l) welded steel water tanks mount at the front of the drill platform. Other tanks are available on request.

Drill Platform

Dimensions vary with the truck and carrier size. Welded construction consists of structural steel and deck plates. Running lights are included.

Rod Rack

Above deck rod rack and underbody rod rack are standard with drill platform. Optional rod storage under the water tank is also available.

Auger Rack

Above deck auger rack is standard with drill platform. Underbody fixed, hinged, or hydraulic auger racks are available.

Tool Boxes

Tool boxes are available for above or below deck mounting in several sizes.

Water Pump

Pump is frame or deck mounted and driven from the rigs’ hydraulic system

  • FMC L0918 (425)
  • Monyo 3L6
  • SP40 Hose Pump

Feed Frame Sheave Mount

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 feed frame sheeve mount can only be used with low overhead clearance feed frame.

Skid

The drill can be mounted on a steel skid with an overall length of 116″(2946mm) and a width of 48″(1219mm). The arm of the skid is removable for ease of drilling.

Towing Rack

The towing rack mounts to the front of the main frame. This allows movement of a skid mounted rig in either direction using the hydraulic winch.

Caster Assembly

Casters clamp to the skid frame for ease of movement on hard surfaces.

Side Shifting Base

Hydraulically operated, side to side provides approximately 6″(152mm) of motion left and right of center.

Drillers Step

Heavy duty drillers step can be mounted on the right and/or left side of the drill platform. The step folds up for storage.

Vertical Drop Hammer Rack

The storage rack for the 140 lb. safety hammer can be mounted in the drill platform or on the back of the hydraulic leveling jack on the cathead side of the drill rig.

Hydraulic Chuck

Hydraulic chuck mounts to top of spindle with jaws available through 3-1/2″(89mm)

High Rise Pump Mount

Allows the Moyno 3L6 water pump to be mounted above two (2) 36″(915mm) tool boxes on the drill platform.

Hydraulic Rod Holder & Breakout Wrench

This device is capable of holding up to 8″(203mm) O.D. drill rods or casing. It slides on and off the hole and also moves side to side. The device stores easily under the rig. A hydraulic breakout wrench is provided.

140lb. Automatic SPT Hammer System

The Diedrich automatic SPT hammer system hydraulically lifts a 140 lb.(63.5kg) drive weight and completely releases the weight for a 30 in.(762mm) free fall. The drive weight does not have a cable or rope attached that may impede its fall. The hammer can be operated at a rate of up to 50 blows per minute. The tolerance of the fall height is plus or minus 3/8 inch(9.5mm). The hammer mounts on the guide tube so that it can be hydraulically raised and lowered and easily moved to the on hole driving position. The hammer can also be operated while suspended from a winch cable. The hammer driving force is transmitted only to the anvil and rods and the hammer allows for up to 24 inches(610mm) of driving without movement of the hammer body. The drive weight, lifting mechanism, and anvil impact surface are enclosed to provide optimum safety.

Carrier/Mast Safety Interlock System

The Carrier/Mast Safety Interlock prevents the carrier from running while the mast is up. This safety device prevents driving the rig into overhead wires with the mast up.
