cates
The rated brake torques can be found on the name plate. The switching times are assigned to the
brake torque in the type examination certi
fi
cate.
Increases in the index (added with
“

) 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
