Auger Boring Machine (ABM)
Technical Description
The Robbins Auger Boring Machine (ABM) is used to
bore horizontally through soil or rock with a cutting
head and auger. ABMs are used to install steel casing
on road, river, and rail crossings.
A starting pit is used to launch the ABM on a
predetermined length of track. The machine
excavates with the cutting head, while jacking force
is provided by hydraulic thrust cylinders. Steel
casing pipe and auger sections are added as the
machine advances. Spoil is removed from the auger
through the casing to a door located on the side of
the master pusher.

A Versatile Solution
The Robbins ABM can be used in a variety of ground
conditions, from soil to hard rock. The machine is
made for use with SBU Products in hard rock, as well
as with soft and hard soil cutterheads. The ABM is
capable of excavating soil, sand, clay, cobble, glacial
till, soft shale and some sandstone. Both the
SBU-A and the SBU-M are the ideal attachments
to be used with the Robbins ABM in hard rock and
mixed ground.

ABM APPLICATIONS:
• Soft ground utility installations
• Hard rock utility installations (with SBU products)
