One of the most common applications for the Akkerman single stage GBM 240A jacking frame is its use in conjunction with a standard auger boring rig. Combined, the GBM offers auger boring rig contractors the ability to provide reduced casing diameters and longer drives with extreme accuracy that are unobtainable with an independent auger boring rig. 800.533.0386, akkerman.com

Bor-It Mfg.

From alluvium to cobbles, the Robbins Small Boring Unit (SBU-A) is making short work of mixed ground. A circular cutterhead, available in diameters from 24 to 72 inches, is custom designed for crossings up to 500 feet long. Each cutterhead is used in conjunction with an Auger Boring Machine (ABM). At a recent project in Clinton, IA, contractor L.J. Keefe utilized two SBU-As and a larger 72 inch Motorized SBU (SBU-M) for successful crossings below a river and highway. The machines completed crossings ranging from 200 to 395 feet long in hard clays—holing through almost exactly on line and grade. 440.248.3303, therobbinscompany.com
