Brake bracket, type BB-46 and BB-85
Brake assembly, type BA-43, BA-63 and BA-85
Each brake is available in three versions depending on their brake direction clockwise, counter-clockwise
and double acting.

Design criteria:
1. The Viking band brakes are fatigue resistant for                        2. The brake is intended to be used as a parking
   the maximum motor torque in each motor series.                             brake.
   The failure criterion is, after an infinite number of
   braking sequences, one brake out of one                                 3. For hanging loads in wet enviroments we
   thousand brakes will be expected to fail. For one                          recommend the use of a protective cover over
   braking sequence, the factor of safety is 5. A left                        the band brake.
   hand brake is used with a left hand motor and a                         4. The brake linings are of non-asbestos material.
   right hand brake is used with a right hand motor.
   When used in the opposite direction to the                              5. The brakes have DNV type approval.
   designated braking force direction, the braking
   torque is 20% of the normal capacity and the
   brake is not fatigue-safe.
