3.1:
3.1:
The brake covered by this manual is type MST/E. This brake has an adjustable external torque
spring and is generally applied on installations where the required torque cannot be pre-
determined within well defined limits.
spring and is generally applied on installations where the required torque cannot be pre-
determined within well defined limits.
3.2:
For a given wheel diameter the Association of Iron and Steel Engineers (AISE) determines the
prescribed torque, when applied to 30 and 60 minute rated motors in steel mill applications.
prescribed torque, when applied to 30 and 60 minute rated motors in steel mill applications.
3.3:
When applied to four quadrant drives or other applications where wheel heating can be
accurately predicted, type MST/E brakes can be provided with torque values in excess of the
AISE recommendations.
accurately predicted, type MST/E brakes can be provided with torque values in excess of the
AISE recommendations.
3.4:
When the load cycle requires a larger than normal wheel size, as is frequently the case on crane
bridge drive, MST/E brakes can be provided with torques lower than AISE for a given wheel size.
bridge drive, MST/E brakes can be provided with torques lower than AISE for a given wheel size.
3.5:
For applications where larger than normal running clearance is required, a larger actuator can be
applied to a given brake. Typical would be severe applications where wheel expansion can be
considerable or where excessive wheel run-out can be expected.
