Selection Guide
Which CATRAC is right?
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.
If you need assistance or have any questions on
special applications, feel free to contact our application
engineers.
