CATRAC® is used on various types of machinery as
a means of safely and effi ciently conveying power,
electrical, air, or fl uid (or a combination of these) to
equipment in motion. CATRAC is designed to be
maintenance free and to protect cables and hoses from
abrasion, wear and twisting. A wide variety of options are
available.
split aluminum bar carriers, rod carriers, removable pipe,
spring loaded rods, vertical pins, double deck, custom
radius “M” dimension (including double radius), custom
and special widths, including single widths, double
widths, triple widths, etc.. We offer various support
systems from a single stationary roller support to a
complete CATRAC carriage support system.
The center pivot design allows for smoother cycling and
minimal hose movement. The CATRAC design offers
“No Pinch Points” to insure operator safety. Standard
side links are high tensile steel for maximum strength.
Steel CATRACs are zinc plated with a yellow dichromate
dip for superior corrosion resistance. Optional materials,
such as aluminum and stainless steel are available.
We also offer a line of Mill Duty CATRACs that are used
in rugged applications and environments such as steel
mills. These CATRACs offer a box beam type carrier
for maximum strength and stability. Spring loaded rods
offer the customer easy access to cables and hoses.
They also eliminate the concern of fi tting sizes that must
pass through the (fi xed) compartment opening on a box
beam style carrier. Hardened shoulder bolts and locknuts
(referred to as bolted construction) are recommended
for use in rugged environments. The CATRAC is
manufactured so that pieces or sections can be removed
or replaced in the fi eld.
Our CATRAC product offers: a variety of sizes from 2.00”
to 14.00” high links, carrier options from welded carriers,
We can provide you with the optimum system to suit
your needs either with our standard carriers and options
or by means of a custom designed system to meet
your specifi c requirements. In addition to our standard
systems used in a standard linear motion, we can also
provide you with double radius side mounted systems.
Contact our applications engineers for additional
information or to discuss your needs in detail.

1. Determine the outside diameter of the largest cable or
hose to be carried.
2. Determine total machine travel. Unsupported length
of CATRAC® on horizontal applications is total travel
÷ 2 when no supports are used and the stationary
mounting foot is placed at the center line of travel.
3. Determine total weight to be carried per foot.
4. Use the charts to select the proper CATRAC style for
your application. Please note that hose area varies
with type of carriers used.
5. Determine the rolling radius of the CATRAC by:
A) Minimum bend radius of cable or hose
recommended by the manufacturer. If this is not
available, we recommend a minimum of 6 times the
O.D. of the largest cable or hose.
B) Space limitations. The “M” dimension of the
CATRAC must be less than the available space where
track will be installed. The rolling radii shown in the
dimension pages are standard. Special radii and “M”
dimensions are available to suit your application at no
additional cost.
6. Determine CATRAC “X” or inside width. Add the O.D.
of all cables and hoses. Allow a minimum of 0.12”
between each hose or cable and on both sides of the
CATRAC. If vertical separators or hose straps are
used, additional clearance is required.
7. Determine the length of the CATRAC. If the mounting
foot is placed on the center line of travel as shown on
the dimension pages, CATRAC Length = “RL” (radial
length) + 1/2 of total travel (T/2). If the mounting foot is
placed on either side of center line, the distance from
the center line to the mounting foot (Y) must be added.
8. Determine mounting feet requirements and positioning
on the CATRAC assembly.

Available on 2CP, 3CP, 203, 375, 304 style tracks, this
tubing is used to hold the entire CATRAC® together. They
are fastened to links with a self tapping screw that can be
removed from top or bottom rod to make installation of
hose or cable easier.
WC Welded Carriers
The carrier is widely used in very rugged applications. It
can withstand severe hydraulic shock and has no loose
parts which can be lost during installation of the hose
cable. The welded carrier bars alternate position top to
bottom on styles 203, 375 and 304. Styles 456, 606 and
808 use a box beam construction with top and bottom
beams across from each other for added strength.
RP Removable Pipe (Standard)
This assembly provides easy installation of cable and
hose. The pipe can be removed by knocking out a roll pin
and pulling it out the side of the CATRAC.
SL Spring Loaded Removable Pipe
This design provides the quickest way to install or
change cable and hose in the fi eld. Simply compress the
plunger and pull the pipe out. No screws or pins need
to be removed and no side space limitations need to be
considered.
1/2” wide aluminum or 3/4” wide wood split bar carriers
can be provided. This carrier is custom machined to your
specifi cations. Note: Holes must be at least 1/8” larger
than cable hose diameter.
VP Vertical Pins
Vertical pins, also referred to as separators or dividers,
can be welded into RP, SL and WC style carriers to
separate cables or hoses to prevent twisting or overlap.
Extra Heavy Duty (Mill-Duty) Construction
For steel mills and other heavy duty service, the double
welded carrier (MD option) is used as well as bolted
construction (BC option). This structure has the ultimate
strength for a carrier. Box beam construction is standard
in the 456, 606, and 808 styles and can withstand severe
hydraulic shock loads.
Optional & Special Carrier Designs
Special perforated carriers can be supplied which provide
openings for hose straps. The hose straps, if used,
should be very loose and used as a hose and cable
separator rather than a tie down.
Many carriers and stiffeners are designed in cooperation
with our customers. We welcome ideas to fi t your specifi c
application needs.

CATRAC® with roller support systems
The roller supports provide a means of
maintaining the maximum unsupported length
while increasing the total travel. There are four
methods of extending the total travel:
1. Utilize a CATRAC with a high side link which
provides a greater unsupported length.
2. Utilize stationary roller supports.
3. Utilize a combination of stationary and
retractable roller supports.
4. Utilize a carriage support system.

This industry readily accepts only those products that
are made exceptionally strong to the point of being
“overbuilt”. If the product doesn’t look like it belongs in
that environment, it doesn’t.
Reliability is the Foremost Requirement
This industry knows no product that they can’t destroy
regularly, our mill-duty CATRACs are designed to be the
most rugged assemblies available.
CATRAC is Stronger
All steel construction fabricated from 80,000 lb. tensile
steel links, assembled with 9/16, 3/4 or 1” hardened
shoulder bolts and locknuts, welded box beam carriers
absorb side thrust loads, can be made to travel and span
the longest distances in the industry.
Cable & Hose Replacement is Easy
The box beam carrier has free space that allows the bad
cable or hose to be easily snaked out. The carrier bars
can have spring loaded retaining rods, allowing the whole
bundle of hoses to be removed and replaced at once.
Available in Any and ALL Sizes
Made to any width or radius with more hose and cable
carrying capacity in a box beam carrier, it can handle 8”
I.D. hose or 12” O.D. cable. We also offer multiple widths
and double deck carrier assemblies.
Retrofit into Present Track Systems
CATRAC is the only known track that can be easily
and regularly made to retrofi t into competitors original
applications. We need only four dimensions to build
CATRAC:
We’ll deliver a stronger system quicker, and at a minimum
cost.
CATRAC is Field Repairable
Because the CATRAC is all steel, it can be straightened
or welded in position. It can be easily unbolted to replace
carriers and links.
CATRAC Value
The competitively priced CATRAC offers more options
for your dollar. Since 1967, CATRAC brand carriers
have been solving customer problems. These years
of experience have supplied us with an opportunity to
provide solutions for numerous applications. This data
allows us to incorporate new and better features into all
CATRAC styles.
Stainless steel chip covers protect hoses against damage
from hot metal chips. The chip covers fi t over the full
length of the CATRAC® assembly, on either the top or
bottom or both sides for maximum protection. The ends
of the chip covers extend six inches beyond the ends
of the CATRAC assembly for attachment. Chip covers
should be fastened on either end to allow them to roll
with the CATRAC. When ordering, specify either outside
or inside covers or both.
Heavy Duty Mounting Feet
Heavy Duty horizontal and vertical mounting feet are
made from 3/16” or 1/4” plate steel and provide the
ultimate in strength at the mounting point. Typical
applications include mill duty equipment and high speed
applications. Custom designs are also available upon
request.
CATRAC

Options
Glide Bars and Transfer Bar for Side Mounted
Applications
We offer a wide range of options for side mounted
applications including Nylatron glide bars, round pads
and steel or stainless steel ball casters. We can side
mount virtually any style of CATRAC. Dual radius
CATRACS are also available for rotary applications.
Multiple Carrier Widths
All styles of 3 Pin Center Pivot CATRAC are available
in multiple widths. This type of construction provides
additional strength in wide systems. When width is
a problem double decking of compartments is also
available.
SnapTrac® was developed to offer a light weight, low cost
carrier for protected and controlled movement of cables
and hoses. This corrosion resistant, nonconductive carrier
is made of a longwearing nylon composition. SnapTrac
can be used with electric, air, gas or hydraulic hoses.
A variety of carriers are available offering solutions for
every type of travel. Typical applications for this carrier
include robotics, machine tools, and all types of industrial
equipment. Our application engineers are at your
disposal to study and solve problems related to complex
applications.
Technical Characteristics
Light and secure even at high speeds, SnapTrac
carriers will provide protection for the components
inside the carrier. The carrier is durable against harsh
corrosive environments as found in refi neries and
marine application, chemical fumes, refrigeration fl uids,
lubricating oils and solvent present in a temperature
range from -13°F to 257°F.
Choosing a Carrier
The designer must consider the travel length of the carrier
and the minimum bending radii of the hoses to be carried.
The additional load per foot must also be considered.
Layout of Cable in Carrier
Observe the allowable minimum bending radii of the
cables and hoses to be carried; it is advisable to add an
additional 10%. Cables of small diameter may be grouped
together and tied.
Small to medium size SnapTrac with yellow connecting pivot
pins offer high capacity in high performace applications.
Available with snap open cover or closed styles.
A strong design with triple connecting pivot pins. This design
allows unsupported length up to 6.5 m and extends the
service life of the SnapTrac and cables.
