TRACK HDD WORK IN HIGH-INTERFERENCE ENVIRONMENTS

Designed specifically to perform in high-interference environments, the Marksman HDD

Guidance System offers a wide range of frequencies in a single beacon.

“Interference can negatively impact job site productivity,” said Alex Wagner, product marketing manager. “But

Marksman cuts through the noise. . . you can confidently go downhole with 64 power level and frequency combinations at your disposal. The Marksman’s

Bore Path Analyzer scans the most usable frequencies, selecting the best choice to avoid interference so you can drill more effectively.”

According to Subsite, Marksman’s beacon performance drives bore productivity in other ways as well. The new guidance system offers improved communication between the tracker and beacon at extended depths (130+ feet). The beacon’s dual-power mode offers consistent performance across housing sizes. Calibration speeds have also been increased.

Ease-of-use was another key element in the design of the Marksman system. The tracker is operated with a single toggle control, with no extra buttons or triggers. The system also gives operators their choice of user interface. The all-new Marksman View is easy to learn, featuring intuitive graphics and clear data, while those already familiar with Subsite trackers will recognize the Classic View interface. The streamlined controls and choice of user-friendly interfaces work together to help operators be more productive from day one.

Marksman offers two advanced locating methods. Users can select between Walkover Mode, which lets you pinpoint drill head location with peak and null techniques, or an improved Drill-To Mode with an unrestricted extended range that enables the drill operator to make real-time corrections further out, expediting the drilling process.

EQUIPMENT CORPORATION OF AMERICA

BAUER CRANE PAIRED WITH BERMINGHAMMER LEAD ASSEMBLY DRILLS DEEPER

Equipment Corporation of America (ECA) is bringing the unique BAUER MC 96 Duty-Cycle Crane paired with hanging Berminghammer lead assembly to

North America to enable its customers to achieve drilling depths of up to 150 feet (45 metres). Both ECA and ECA Canada will offer this rig to customers for sale or rental.

“ECA is thrilled to add this BAUER MC 96 Duty-Cycle Crane equipped with a Berminghammer leader and a powerful BAUER KDK 280S Rotary Head to our fleet,” says Director of BAUER Product Sales and Service Gordian Ulrich. “This rig can drill up to 150 feet of single-pass piles (CFA or FDP) in various diameters, which is 25 feet more than our BG 45 in the high-end CFA set-up.”

When equipped with the 138-foot-long (42-metre) Berminghammer lead, BAUER’s 130-ton duty-cycle crane can reach depths of up to 150 feet (45 metres). The specially adapted MC 96 mast geometry allows an operator to drill in single-pass mode using the complete mast length. This means that the 750-mm auger can achieve a depth of 115 feet (35 metres) in a completely continuous drilling process. It is also possible to attach a Kelly extension to drill down an additional 33 feet (10 metres).

This customized rig represents a partnership between two of the world’s leading manufacturers of foundation equipment. Berminghammer and BAUER Maschinen collaborated to develop this special lead set-up specifically for the MC 96 series of duty-cycle cranes in 2020.

BAUER and Berminghammer also developed special joint kinematics to allow the lead itself to be rigged easily and quickly. No additional modifications are required to connect the Berminghammer lead to any MC duty-cycle crane.

In addition to the latest drilling features such as drill or pull assist, this MC 96 uses a standard BAUER KDK 280S Rotary Head, which is powered by the on-board Caterpillar C18 engine. This means that no additional power pack is required, which reduces noise levels and operating costs.
