The dual acting
calipers minimize
shaft bending that
occurs with single
acting calipers.
They are typically
used on extended
gearbox shafting or
motors that are not
built to mill duty
standards.
The PT Tech CDB-A
Caliper Disc Brakes
are designed to
upgrade AISE and
CMAA cranes to the
higher performance
and the ease of
maintenance of a
caliper disc brake.
Upgrading to the PT
Tech Caliper Disc
Brake will result in
the following
advantages:
1) Wear adjustment
is far easier.
2) Less frequent
need for wear
adjustments.
3) Improved wear
life.
4) Replacing
friction pucks is
substantially
quicker.
5) Friction pucks
weigh less than drum
brake shoes.
6) Eliminates drag
and slip problems
due to drum thermal
expansion.
7) Significantly
better resistance to
heat checking.
8) Sealed and
lubricated pivot
points.
9) Coils are common
to three size
brakes.
CDB-A Brakes have
the same mounting
bolt hole pattern as
the drum brakes they
replace. CDB-A
Brakes conform to
the new AISE Brake
Standard published
in August, 1997. |

Mounting bolt hole
pattern meets AISE
Brake Standard #11.
Centerline of the
disc maintains the
same position
relative to the
motor as the center
line of drum. Second
caliper is removed
to allow for ease of
installation. |
