Congratulations and thank you for purchasing a TRIC pipebursting system. is visual guide
provides basic yet comprehensive instructions for safe, eective operation and care of your TRIC
equipment. We want to familiarize you with the critical working elements of your TRIC pulling
unit and bursting head assembly, and to illustrate the essential best practices with your system. Our
goal is not to describe every possible bursting scenario, but rather to create a convenient reference
to facilitate more trouble-free operation, and above all to encourage safety on the job.
To that intent, please note the warning symbols in this user guide, which indicate two
levels of concern. e yellow symbol warns against mechanical failure or undue stress
on equipment. e red warning indicates danger of physical injury or death. In some
cases both warning symbols will be displayed at once. In any case, please pay close atten-
tion to all safety topics covered in this manual. SAFETY FIRST!
We are continually improving our products and actively testing them in the eld. We also maintain
working relationships with many of our customers, thus their experience is ours. We are happy to
share this information, along with the latest updates and tips, at www.trictools.com. Or feel free
to call us at 888-883-8742. Welcome to the TRIC Team!

INTRODUCTION
e heart of every TRIC pipebursting system
is a cable-pulling device. Cable, or wire rope,
has been essential to the TRIC method since the
company introduced trenchless home sewer lateral
replacement in America back in 1996. Residential
sewers typically have directional changes between
the building foundation exit point and the property
line or municipal sewer main connection. A cable is
the best way to negotiate these bends. By contrast,
larger municipal sewer pipes generally maintain a
straight ow path, and each change of direction
becomes an accessible service point, or manhole.
TRIC equipment leverages the unique qualities of
steel cable to replace more pipe with less excavation,
especially in dicult easements and other hard-to-
access areas. is is also true for other underground
utilities such as water and gas.

11
Steel cable is valued for its exibility, compactness,
resiliency, and high strength-to-weight ratio. e
standard TRIC conguration employs a wheel that
directs cable and pulling force from horizontal (pipe
ow path) to vertical. is conguration allows for
great power in a relatively small footprint, and also
provides easier access to the puller and grippers.
As with all heavy-duty construction equipment, the
TRIC system must be used with caution and good
planning. e following pages illustrate the safe and
eective use of your TRIC M-Series pipebursting
system. Please review this information carefully.
NOTE: Your hydraulic power source (i.e., pump
or power-pack, PTO device, or excavation equip-
ment) is not covered in this manual. Please refer
to original manufacturers for further information.

BURSTING SETUP
e rst step in any pipebursting job is to locate
and expose the existing pipe at each end of the
service line to be replaced. Drain lines should
be recently inspected and located by video, with
all depths, bends, transitions, connections, and
service points marked on the ground surface.
Entry and exit pits are congured dierently
from one another, and can have vastly dierent
excavation requirements. Figures 2 and 3 on the
following pages illustrate entry (launch) and exit
(pulling) pit congurations.
TRIC M-Series pipebursting units are designed
primarily to serve the municipal utilities market.
is includes underground sewer, water, and gas
lines in a variety of pipe materials ranging from
2” (50mm) to 20” (500mm) in diameter.
TRIC also manufactures a variety of bursting or
splitting heads, each specic to the type and size
of pipe to be replaced. Please see Figure 1 on the
opposite page for a selection of bursting heads to
replace dierent host pipes.

BURSTING SETUP
HDPE pipe is exible, which is indispensable
for pipebursting applications. e combination
of pipe diameter and wall thickness (known as
SDR or Standard Dimensional Ratio) deter-
mines the level of exibility for each pipe size.
A safe formula for the excavation of entry pits
for municipal sizes of HDPE pipe is a 30º access
angle or ramp down to pipe level. is translates
to a surface cut that is roughly twice as long as
the pipe is deep. Smaller pipe sizes (150mm and
under) have smaller bending radii. Figure 2 on
the facing page illustrates a typical municipal
entry scenario.
a= Variable
b= 2’ (60cm)
c= 6”–12” (15–30cm)
d= 36” (90–100cm)
e= 8”–12” pipe (200–300mm)

Municipal pipelines (especially drains and
sewers) generally require larger entry and exit
pits due to their size and depth. When using the
M-Series units (especially the M100), a trench-
box is indispensable for stabilizing the pulling
assembly, and for extracting the bursting head
at the end of the pull. Figure 3 on the opposite
page illustrates setup behind a trench box.
Figures 7 and 8 on pages 20 and 21 show typical
eld applications of the M50 and M100 in
conjunction with manhole boxes or heavy-duty
trench boxes.

BURSTING SETUP
e M100 (shown here) is typically equipped
with either 1-1/8” (28mm) or 1-1/4” (32mm)
compact swaged wire rope. ese cable sizes
are much heavier than those used with TRIC
lateral systems. When loading the cable into
the M100, it is sometimes helpful to engage the
top (pulling) grippers rst, and then extend the
puller to draw slack out of the cable and bring
it into the lower or retaining grippers (Figures
4 and 5 on page 18). Also, the M100 may have
gripper stop-screws at the top of the cover plates.
In Figure 6 at left, red arrows indicate holes for
stop-screws (5/32” or 4mm allen-type), which
must be loosened or removed to allow full
opening of grippers to insert cable. When the
cable is fully engaged, attach gripper O-rings
to bolts on cover plates and grippers (yellow
arrows), to keep grippers engaged to the cable.
