Description
4.1
Functional description
The tirak
TM
is a hoist for raising and lowering loads. The hoist is
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.
The electromagnetic spring-applied brake automatically locks
when the operating control for travelling UP or DOWN is released
or when the power fails. A centrifugal brake prevents rope
speeds that are too high when lowering the load manually.
The load bearing capacity of the hoist can be multiplied accord-
ing to the block and tackle principle by reeving the rope. See
'
4.9 Increasing the load bearing capacity' on page 8.
Press the EMERGENCY OFF 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 have a
mechanical load limiting device. Hoists with a load bearing ca-
pacity of 1,000 kg or greater can be optionally equipped with an
electrical or a mechanical load limiting device.
The load limiting device turns off the hoist at the latest once the
load reaches 1.25 times the load bearing capacity.
T-Model series:
Hoists of the T-model series can be optionally equipped with an
electrical load limiting device.
The load limiting device turns off the hoist at the latest once the
load reaches 1.25 times the load bearing capacity.
