Brake Selection
The brake size must be chosen to give required braking torque and to dissipate the energy during stopping without over heating the disc. Brake torque is often related to drive motor torque by an arbitrary service factor typically 75% -100% full load torque for crane travel and similar inertial loads which tend to be self stopping or 150% -200% for crane hoists and other overhauling loads. If a precise stop time or distance is specified, then the brake torque must be calculated.

Motor FL torque is given by:
   - [(kW x 9550) / rpm]Nm or [(HP x 5250) / rpm]Lbft

Dynamic Torque is calculated by:
[(AF x 0.5 (D-F)) / 2000]Nm or [(AF x 0.5 (D-F)) / 24]Lbft
(1) For discs outside the range, please call
Static Torque is calculated by:
[(AF x 0.4 (D-F)) / 2000]Nm or [(AF x 0.4 (D-F)) / 24]Lbft
(1) For discs outside the range, please call
