STRAIGHTLINE HDD Expands Hole Opener Lineup

XL-I Series Hole Openers Are Designed From the Ground Up For HDD

StraightLine HDD recently expanded its hole opener offering with the introduction of the XL-I Series. Designed from the ground up for horizontal directional drilling, the XL-I Series is positioned as a cost-effective alternative to "split-bit" hole openers.

At the core of the design are proprietary cones—available in six sizes, in either Tungsten Carbide or Mill Tooth configurations. Mounted to a purpose-built platform, the design facilitates load transfer to the shaft and bearing, with minimal radial load. The result is a dramatic improvement in production, service life and consistency, bore after bore.

Next, designers set out to address wear and performance characteristics by re-examining the interplay between cone diameter, height and carbide placement. Cones are sized and attached to the baseplate at an angle that protects vulnerable surfaces. Shortened cone height further improves wear resistance. Carbides placed to cut independent paths yield higher efficiency and longer service life.

Internally, the cone's proprietary sealing and bearing system mitigates fluid intrusion, yielding a myriad of user benefits, from reduced torque and fuel consumption to extended tool life.

As a platform, the XL-I Series incorporates design characteristics that ensure the tool's original geometry is maintained—even after rebuild. This approach yields consistent and repeatable performance.

The XL-I Series includes six sizes, from 12.75- to 24-inches with IF Box x Box shafts.

Herrenknecht tunnel borers continue success story in L.A.

Los Angeles is a vibrant center of international film art and innovation - not just on the surface. The area below ground is the scene of state-of-the-art engineering achievements. German high-tech machines from Herrenknecht are creating underground arteries for the American city. Tunnel boring machine (TBM) , Harriet successfully completed her drive for the Crenshaw/LAX Transit Project in April 2017. Angeli just finished digging the first of two tunnels for the Regional Connector Transit Corridor on July 18th. From spring 2018 onward the tunnel boring stars will have additional company: for each of the "Purple Line Extension Sections 1 + 2", two more Herrenknecht TBMs will be working their way through the difficult ground. All three projects are part of the strategic subway extension in L.A. to relieve the traffic above ground.
