The D24x40 series II is one of the newest drills the IC fleet of Horizontal Directional Drills. This machine is fitted with a rack & pinion set up replacing the old chain configuration. The HDD uses a conventional drilling system which transmits mechanical power from the rotation unit and feed boom, through the drill rods to the drill head. The D24x40 series II can drill through a wide variety of ground condition including dirt, clay, sand, shale and some sandstone. The drill is fitted with a new RATT rock capable system giving it that extra ability is penetrate some of the toughest rock conditions while still achieving steerability. It is ideal for installing multiple conduits to a distance up to 200 metres but can complete projects up to a maximum of 250 metres, depending on the ground conditions and product to be installed. The drill uses 3 m long rods and is fitted with an automated rod loading system.

The D24x40 series II uses a Digitrak MkIII system locate the drill head while drilling. This allows the drill head to be track at a maximum depth of approximately 20 metres deep. Along with a mixing system attached to the support truck ensures that the D24x40 series II is a self sufficient unit able to complete a project with only minimal support.

Machine: Ditch Witch 2720 All Terrain
Type: Horizontal Directional Drill

Dimensions

The 2720 All Terrain system is designed to steer and back reamer through virtually any type of soil over a distance of up to 200 metres. This includes the ability to drill not only rock, but through cobblestone, broken rock, gravel and caliche. To achieve this ability the machine is equipped with an advanced dual-drive Power Pipe system. This unique shaft within a pipe system features a strong hex shaped rod which turns inside an outer pipe. The inner hex shaft works as a mechanical motor that drives the bit during the bore, the outer pipe thrusts the bit forward, steers the drill string and works to transmit full machine torque during back reaming. With only minimal water flow (7-15 gpm) required to operate the drill bit when in rock, the chance of a frac-out is remote compared to other machines requiring the use of a mud motor which needs 80 gpm plus to achieve a result.

To enhance its advanced rock system, the 2720 AT is also fitted with a highly productive cruise control feature which once set to the ground conditions can maintain desired thrust, pullback and rotation settings. Along with a fully automated rod loading system containing 98 metres of on board rods (additional rods available) makes this a very compact and self contained machine. The 2720 AT will also be used in conjunction with a new mud recycling system which holds up to 1200 gpm. This unit will allow the water used down the hole to be recycled over the duration of the project making this a very environmentally friendly set-up.
