8. What to do if the safety gripping device engages

If the safety brake engages simply disengage by

pusing down the lever (Fig. 16A) until it clicks.

However this is not possible if the work cage is

hanging on the wire - if so, see below.

DANGER!

On lifting wire breaks or hoist failures,

evacuate sta from the work cage.

The safety wire suspension and the attachment

between the safety brake and the work cage

are exposed to dynamic loads when a fall is

blocked.

If the safety brake has locked and the work

cage is hanging on the wire ascending is

blocked. Do as follows:

a) Remove the load on the safety wire by taking

the work cage upwards

- On power failures operate the work cage

manually as explained in section 7.2.

b) Manually open the two safety brake by

pressing down leavers (Fig. 16A) until they

disengage. On ground level perform test as

speciﬁed in Installation Manual section

4. e) and User’s Manual section 5.6 before

resuming normal operation.

ATTENTION!

When the work cage has returned to

ground level, test the safety brake

function as speciﬁed in Installation

Manual 4 e) and User’s manual 5.6.

CAUTION!

Replace any defective safety brake

components and return them for

repair to the manufacturer.
