January 22, 2010 - Designed to operate in series with DC motors in crane applications, 12 in. Model CDB0812A caliper disc brake conforms to AIST dimensional standard. It is spring applied and electrically released, and has same mounting footprint as 8 in. drum brake. Upgrading crane with Model CDB0812A simplifies wear adjustment, eliminates drag and slip problems due to drum thermal expansion, and offers resistance to heat checking.

PT Tech's New CDB0812A Replaces 8" Drum Brakes and Conforms to the New AIST Brake Standard


o Spring applied

o Electrically released

o Operates in series with DC motors

o Installation requires no modification

If the installation conforms to AIST's dimensional standard for DC mill motors, then when ordering all that is required is the DC mill motor number and existing electrical coil specifications. In all other installations, please provide a drawing of the existing brake drum.

o 12" inch disc replaces an 8" drum

The CDB0812A caliper disc brake provides higher performance and easier maintenance than the drum brakes it replaces. Upgrading your crane with PT Tech's CDB0812A 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) A set of friction pucks weighs only 4½ pounds.

6) Eliminates drag and slip problems due to drum thermal expansion.

7) Significantly better resistance to heat checking

PT Tech supports its commitment to excellent field service with a large inventory of parts and a 24-hour emergency service.

When Converting

The CDB0812A directly replaces an 8" drum brake. It has the same mounting footprint and torque capacity as an 8" drum brake. When converting, it is critical that the disc's centerline is in the same position as the drum's centerline.

Single-acting caliper disc brakes impose a bending moment. Shafting should be reviewed prior to installation. Consult PT Tech.

In most cases, PT Tech can suggest mounting adaptations for non-standard drum brakes. Consult PT Tech.
