DRILL ROD For McCLOSKEY Navigators McCLOSKEY DRILL ROD It may look like a simple steel tube, but today's drill rod carries a heavy load especially when it comes to your bottom line. Considering today's skyrocketing steel and fuel costs, drill rods have suddenly become a very expensive wear item to any HDD operation. That's why it pays to work with proven industry leaders. Melfred Borzall and Premier Drill Pipe have teamed up to offer the highest quality and most complete line of HDD drill rods available. Made in the USA. Drill Rig Model O.A.L.

BACKREAMER HDD PULLBACK SWIVELS Several unique design features of our clevis x clevis swivels combine to make them the strongest on the market. Four bearings and a larger shaft constructed from tool steel provide added strength you won t find with competitors swivels. Full diameter shouldered pins, recessed into the smooth and durable outer casing creates a tremendously strong connection and also allows for snag free pullbacks. These swivels also have side-mounted, recessed grease fittings which protects the fittings and also makes for easy access when performing swivel maintenance.

BACKREAMER HDD MAXI RIG SWIVELS When it comes to Maxi-Rig HDD Swivels Underground Tools will not compromise on quality. That is why we offer only the best, Brewis Big Rig Pullback Swivels. Each swivel uses either a SKF Explorer or FAG X-Life Spherical Roller Thrust Bearing of a specific declared size. Most swivel manufacturers don t declare the bearing capacity of their swivels, but instead quote a figure for the strength of the supporting steelwork; this isn t much help if the bearing has been compromised or has seized up. Our swivels have a dynamic capacity that exactly matches the rating or size of the swivel. Features and Benefits: SKF Explorer Spherical Roller Thrust Bearing of a declared size and capacity Patented sealing system that keeps drilling fluids out but still allows for power greasing Easy access side grease point location for easy maintenance and greasing Manufactured from High Tensile 4145 Steel One piece shaft and clevis provides maximum strength and durability Box x Clevis design or Clevis x Clevis design available Part No. Size/Rating Description A B C D E F G H J Weight/Lbs.

Directional Drilling Locating System DCI is the world s leading supplier of the very best walkover locating technology for the trenchless industry. The DigiTrak F5 Directional Drilling Locating System is the most advanced in DCI s F Series line of locating systems. Over five years in development and backed by over 20 years of HDD locating experience, the F5 platform builds on DCI s industry-standard Eclipse locating technology. The F5 receiver incorporates DCI s patented 3D antenna technology, Ball-in-the-Box locating that lets you walk directly to a locate point from any direction, colorful and intuitive icon-driven menus, a four-way toggle switch, and easy-to-understand graphics, which together provide a best-in-class user experience. Multiple transmitter options with dual in-ground frequency selection DigiTrak DataLog and Log-While-Drilling (LWD) with Bluetooth technology Pilot hole fluid pressure monitoring with Fluid Pressure Transmitter (FPT) Off-track guidance when direct walkover locating is not possible Compatible with SST steering tool and TensiTrak monitoring system The F5 system offers multiple transmitter options in five frequencies to help you overcome jobsite interference better than ever at depths of up to 90 ft. (27.4 m). DCI transmitters can track existing nonmetallic ducts, measure pullback tension and mud pressure, and steer reliably where a direct walkover is not possible. Dual-frequency transmitters can change frequency in-ground, a valuable time-saving feature. FPT fluid pressure transmitters (a technology patented by DCI) monitor pressure in real time to help prevent inadvertent returns while drilling pilot bores. The F5 receiver comes standard with DigiTrak DataLog.Built-in Bluetooth technology transfers this data from the F5 receiver to a PC with Log-While- Drilling (LWD ) software, where a variety of options are available for analyzing, annotating, and displaying data. View both current and past data logged by the F5 receiver even while still drilling.

The DigiTrak F5 receiver gives a bird s-eye view of the relative positions of the receiver and transmitter, a 24-position roll indicator, pilot hole fluid pressure data, and the transmitter s pitch, signal strength, temperature, and battery strength. During a depth reading, the depth display shows a side view of the drill head along with the bird s-eye view, providing the transmitter s location in three dimensions on the same screen. The F5 provides depth readings over the transmitter and predicted depth readings at the front locate point (FLP), allowing for tracking on-the-fly over a level drill path. All of this information is sent to the remote display (FSD) on the drill. The FSD s screen is normally dedicated to the transmitter s roll clock. When the receiver takes a depth reading, the FSD automatically adjusts to also display depth.

This lets you make up/down and left/right steering corrections on the way to the target, resulting in straighter pilot bores. Crisp graphics make this function easy to set up and operate. Roll offset allows the transmitter s 12 o clock position to be electronically compensated to match that of the drill head. The F5 receiver is compatible with the remote F Series Display (FSD ) and Multi-Function Display (MFD ). The F5 system comes with an F5R receiver, FSD remote display, three DigiTrak lithium-ion battery packs, and an intelligent charger with both AC and DC power cords. Transmitters are sold separately.
