The Robbins Company
Designed to work with Robbins SBUs, Robbins Heavy Duty Auger Boring Machines can take on the some of the toughest bores. Several sizes of ABMs are readily available in any bore diameter with standard English (inch) or metric (mm) casing sizes. If it is not in the company’s inventory, they will custom make the machine for your project. The majority of the crossings are 80 feet to 225 feet long; however some drives have been over 600 feet in length. The length of the drive depends on the ground conditions. The machine can excavate sand, gravel, clay and rock of any type. With the Robbins Small Boring Unit, the ABM can excavate rock faster in small diameter drives than any other method available. 440.248.3303, http://www.therobbinscompany.com
