Scope of application
Use as braking device – part of the the protection device against overspeed for the car mov-
1.1
ing in upwards direction – permissible brake torques and tripping rotary speeds
1.1.1
Permissible brake torque when the braking device acts on the
shaft of the traction sheave while the car is moving upward
1.1.2
Maximum tripping speed of the overspeed governor and maximum rated speed of the lift
The maximum tripping speed of the overspeed governor and the maximum rated speed of the lift
must be calculated on the basis of the traction sheave's maximum tripping rotary speed as outlined
above taking into account traction sheave diameter and car suspension.
