Description
4.1
Functional description
The tirak
is a hoist for raising and lowering loads. The hoist is
TM
operated with an electric motor. The X-model series hoists can
raise and lower as well as pull and release in the pulling direction
of the rope. The T-model series hoists can pull in both directions
and are used, for example, for moving loads.
Operation is carried out via a button panel, control box or a cen-
tral control unit.
G932.4 - 09/2015
The electromagnetic spring-applied brake automatically locks
when the operating control for travelling UP or DOWN is released
or when the power fails. When lowering the load by manually
venting the spring-applied brake a centrifugal brake prevents the
rope from accelerating up to a fast speed.
The hoist's payload can be multiplied according to the block and
tackle principle by reeving the rope. See ' 4.9 Load limits' on
Page 9.
Press the EMERGENCY-STOP button to stop the hoist immedi-
ately in an emergency situation.
X-Model series:
Hoists with a load bearing capacity of 1,000 kg or greater are
equipped with a mechanical load limiting device. Hoists with a
load bearing capacity up to 1,000 kg can be optionally equipped
with an electrical or a mechanical load limiting device.
T-Model series:
Hoists of the T-model series can be optionally equipped with an
electrical load limiting device.
The load limiting device will active automatically when the over-
load setting is reached. The downward travel of the hoist is
stopped. The maximum overload that has to be set up can be
found in the applicable directives and standards (See
' 9.1 Directives and standards' on Page 10).
The system manufacturer / operator is responsible for determin-
ing and setting up the application dependent maximum overload.
For further information see ' 15.5 Adjustment, Adjusting the load
limiting device' on Page 20.
