fi
cates
The rated brake torques can be found on the name plate. The switching times are assigned to the

) for a type examination certi
fi
cate are only used for technical
improvements and are approved by the authorised body with this condition.

Calculation of tripping speed
DTS
= diameter of the traction sheave (table contains typical traction sheave diameters, other diameters
can be recalculated linear)
Nbn
= maximum nominal speed of the brake rotor
Nbmax
= maximum trip torque of the brake rotor
Vn
= maximum rated speed of the elevator
Vmax
= maximum tripping speed of the elevator
