ROCKHEAD

(SBU-RHSS OR SBU-RHDS)

The Robbins Rockhead is ideal on longer utility installations (over 150 m) where
line and grade are critical. The Rockhead is available in Double Shield
(SBU-RHDS) or Single Shield (SBU-RHSS) models. The Double Shield Rockhead is
self-propelled using a gripper system. The Single Shield Rockhead must be used
in conjunction with a pipe-jacking system or primary liner erected in the tailshield.
Muck can be removed using a small invert auger or muck cars.

ROCKHEAD APPLICATIONS
• Line-and grade-sensitive crossings
• Replacement for carbide bit and t t
roller cone cutterheads
• Long bore lengths
• Pipe jacking up to 300 m+tt
• Tunneling up to 600 m+

GUIDED TUNNELLING
The Rockhead can be steered
throughout the drive from an
operator’s console inside the rear
shield. Articulation cylinders
and stabilizer pads allow for
continuous control of line and grade.
The machine’s heading can be
continuously monitored using a laser
targeting system.

A COST EFFECTIVE
SOLUTION
The Rockhead offers more efficient
excavation than typical carbide bit
or roller cone cutting heads. Most
carbide cutting tools tend to break
off in rock above 50 MPa UCS. The
Rockhead uses disc cutters to chip
away hard rock from 25 to over 175
MPa UCS.
