ThyssenKrupp Aufzugswerke GmbH
Changing, exceeding the specified ratings
Deficient monitoring of parts that are subject to wear
Repairs that are carried out improperly
Cases of catastrophe due to third-party interference and force majeure.
Constructional changes to the NBS emergency brake
The components of the NBS emergency brake are assembled and tested in
the plant. In event of changes being made to the assembly, all warranty on
the part of THYSSENKRUPP AUFZUGSWERKE GmbH is cancelled
Dangers in handling the NBS emergency brake
The internal electronic circuit of the NBS emergency brake is connected to
mains voltage. Before intervention in the control system, required for
example with the safety catch activated or during a brake test, the power
supply to the drive is to be disconnected before starting work and the
installation is to be secured against inadvertent activation.
In the event of improper use, there is a risk of personal injury or to the life of
the user or third parties, or impairment of the assembly or other assets can
arise.
Malfunctions that can impair safety must be rectified immediately.
Make sure that the brake release screws (screw head marked in red) have
been removed from the NBS emergency brake before beginning operation of
the elevator, as otherwise the brake will not function in an emergency.
No persons may be transported (except emergency rescue) with the
brake release screws screwed in!
