(57) The invention relates to an arrangement for a stores crane for internal materials
handling comprising a load carrier (16) so arranged as to run along guides (22) on
a vertical crane mast (12) and a lifting device (18) for the load carrier arranged
for displacement of the load carrier along the mast. A fall brake (26) is attached
to the load carrier for the purpose, in the event of a fault in the lifting device,
of preventing the load carrier from falling downwards through engagement with the
guides. A detector device (27) is so arranged as to sense the movement of the load
carrier and, in the event of deviation from set values, to actuate the fall brake.
This exhibits a brake housing (30) with a moving wedge-shaped brake body (33) capable
of moving against one of the guides (22) and along a support surface (45) angled against
the guide in the brake housing (30). The movement is controlled so as to take place
between a first, non-braking position and a second, braking position in which the
brake body (13) is in contact under the effect of the wedge with both the guide (22)
and the support surface (45). The brake body (33) incorporates a scraper device (52)
so arranged, on the one hand, as to scrape the guide (22) clean from dirt and, on
the other hand, as to displace the brake body (33) towards its braking position through
an initial frictional force.
