Wire rope, products in contact with the rope and rigging must not
be soiled by heavily soiling building materials such as concrete,
epoxy resin or other adhesive materials. Protect the products
against soiling! Always use brush attachments to clean the wire
rope in an extremely dirty environment.
Anchoring point
The structural equipment to be used for attaching the product
must be designed in compliance with the applicable Directives
and standards (see ' 9.1 Directives and standards' on page 11).
The application's overall suspended load must be taken into
account regarding the design of the suspended construction. The
overall suspended load is the actual suspended static load,
which is made up of the payload, the load lifting equipment's own
weight, the additional fittings, the wire ropes and the control and
connection cords.
If necessary, a test report must be included, in which the static
and dynamic tests that were run are described in detail.
Drive path
During lifting processes the drive path must be limited by one or
multiple limit switches, so that the upward and/or downward
movement is stopped.
The operator or the system manufacturer must determine the
design and the fitting position of the limit switches when taking
their risk assessment into account.
The operator or system manufacturer must install an emergency
limit switch and, optionally, an operational limit switch and a floor
limit switch and connect them to the hoist. The limit switches
must have a positive opening.
The gap between the limit switch and the wire rope anchoring or
the protruding components must be chosen so that the machine
can be switched off reliably and in good time. We recommend
that you use a minimum gap (Size a) of between 0.5 to 1.5 m.
See Fig. 9.
The wire rope must be long enough so that the rope end connec-
tion or the load bearing point or the rope end itself cannot be
pulled up to or into the product or the accessory parts.
Operating equipment
It must be possible to position the operating equipment in such a
way that safe operation is always possible regardless of the
movements of the hoist.
The control buttons must be arranged so that there is no possibil-
ity of confusion.

Running hours counter
The running hours counter is located in the hoist's terminal box.
The running hours counter counts the time in which the hoist is in
operation as running hours (UPWARD and DOWNWARD
movements). To read the running hours counter: See
' 15.3 Reading the running hours counter' on page 21.

Description

4.1

Functional description

The tirak is a hoist for the transport of persons or for persons
TM
and materials. The hoist is operated with an electric motor.
The hoists can raise and lower as well as pull and release in the
pulling direction of the wire rope.
Operation is carried out via a button panel, control box or a cen-
tral control unit.
The electromagnetic operating brake (spring-applied brake)
automatically locks when the operating equipment for travelling
UP or DOWN is released or when the power fails. When lowering
the load by manually venting the operating brake a centrifugal
brake prevents the wire rope from accelerating up to a fast
speed.
