PT Tech

CDB Brake

PT Tech caliper disc brakes (CDB) are spring applied, electrically released, and conform to the new AISE brake standard. Compared to drum brakes, wear adjustments are less frequent, and far easier when they are required. Installation requires no modification, as the mounting hole pattern matches existing drum brakes.

Torque range: 65 to 6,000 lb-ft (48 to 4,425 Nm)
Typical application: Replaces existing drum brakes on overhead cranes

HCDB Brake

PT Tech hydraulic caliper disc brakes (HCDB) are similar in size to the drum brakes they replace, and the existing hydraulic components remain unchanged. The HCDB is wear compensating, and friction pucks are easy to change when the time comes. Unlike drum brakes, the HCDB provides the same torque per brake in a two-brake system as it does in a one-brake system.

Torque range: 425 to 900 lb-ft (576 to 1,220 Nm)
Typical application: Replaces existing hydraulic drum brakes on bridge drives

SL Torque Limiter

PT Tech’s SL series torque limiter is designed specifically to protect mining applications. Since this is a friction-type torque limiter, no reset is required after a slip occurs. While slipping, the torque limiter will continue to transmit torque equal to the unit’s torque setting.

Torque range: 3,312 to 4,584 lb-ft (4,490 to 6,215 Nm)
Typical applications: Mining equipment

SLQ Torque Limiter

PT Tech’s SLQ series torque limiter requires no adjustment or lubrication. Since this is a friction-type torque limiter, no reset is required after a slip occurs. While slipping, the torque limiter will continue to transmit torque equal to the unit’s torque setting.

Torque range: 438 to 3,828 lb-ft (594 to 5,190 Nm)
Typical applications: Mining, steel, material handling
