1.1 Terms and abbreviations used in
this manual

The terms used in this instruction manual have the following
meanings:

System / Machine

Pursuant to the Machine Directive 2006/42/EC lifting equipment,
hoisting gear and rigging for lifting are regarded as machines.

The term "system" or also "machine" describes the device in
which the unit described here will be fitted.

System manufacturer

The system manufacturer (system planner, system manufacturer,
installer) is the company marketing the system and all of the
required components. The system manufacturer is responsible
for the design, manufacturing, assembly and marketing.

Rigging

Rigging consists of equipment which does not belong to the
hoisting gear and which creates a connection between the carry­ing means and the load or the carrying means and the load lifting
equipment (e.g. rope loops, round slings, shackles, swivel hooks,
eye hooks, deflection rollers).

Anchoring point

Part of the on-site suspended construction to which the suspen­sion rope, the safety rope, deflection rollers or the hoisting gear
is anchored.

Operating personnel

Personnel who have been trained by the operator to operate the
product and are authorised to operate it.

Operator

The operator is responsible for the correct operation of the sys­tem / equipment and also for adhering to the maintenance inter­vals and the undertaking of the service work.

Electrician

An electrician is someone who possesses sufficient knowledge
or has obtained the required qualification through training in
order to recognise the risks and avoid the dangers that can occur
when working with electricity.

Independent secondary brake

A device for stopping the load lifting equipment in the event of
the suspension rope snapping or a malfunction, e. g. drive mal­function.

Hoisting gear / machine for lifting loads

Device or equipment consisting of a device with load carrying
means for lifting or transporting loads (e.g. wire rope hoist or wire
rope hoist with rope and swivel hook).

Customer / end customer

The customer or end customer is the system manufacturer's
customer and can also be the operator.

Load lifting equipment (LAM)

A component or piece of equipment which does not belong to the
hoisting gear, which enables the load to be grasped and which is
attached between the machine and the load or to the load itself,
or is intended to be an integral component of the load. Rigging
and its components are also regarded as load lifting equipment.

Material lifting equipment (MAM)

Load lifting equipment for material.

Nominal load

The nominal load is the load bearing capacity of the hoist and is
the load that is applied to a certain position, e.g. on a deflection
roller. Simple reeving doubles the nominal load.

An appointed person who has undergone the appropriate training
and who, due to his knowledge and practical experience, is able
to safely perform the required work when provided with the nec­essary instructions.

tirak™

tirak™ is used in the text as the abbreviation for the hoist.

Load bearing capacity

The load bearing capacity specifies the maximum load the hoist
is allowed to lift or pull. The load bearing capacity can be multi­plied by reeving the rope.

Carrying means

The carrying means is equipment connected to the hoisting gear
for attaching load lifting equipment, rigging or loads (e.g. a hook
permanently attached to the suspension rope).

Maintenance personnel

A person appointed by and trained by Greifzug Hebezeugbau

4 Description

4.1 Functional description

The tirakTM 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 cen­tral 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 accord­ing 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 immedi­ately 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 ca­pacity 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.

Mechanical load limiting device

X-Model series:

y From 1,000 kg load bearing capacity
y Up to 1,000 kg load bearing capacity optional scope of

delivery

The load limiting device switches off automatically if overloading
occurs. When delivered, the load limiting device has been set in
such a way that it deactivates the hoist at the latest once the load
reaches 1.25 times the load bearing capacity.

Electric load limiting device (optional)

The electric load limiting device switches off automatically in
case of an overload. The load limiting device reacts to the power
consumption of the motor. Hoists with two speeds are equipped

Installation and operating manual

EN-8 G932.1 - 06/2010

ENEN

with two electric load limiting devices. An overload is recognised
when lifting. When delivered, the load limiting device has been
set in such a way that it deactivates the hoist at the latest once
the load reaches 1.25 times the load bearing capacity.

Spring-applied brake

The electromagnetic spring-applied brake automatically locks
when the operating control for travelling UP or DOWN is released
or when the power fails.

Centrifugal brake

A centrifugal brake on the motor shaft of the hoist ensures that
the load is not lowered too fast when the spring-applied brake on
the hoist’s motor is released manually.

Limit Switch / emergency limit switch

The path of the hoist for lifting 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 a limit switch
and, if necessary, an emergency limit switch and a floor limit
switch and connect them to the hoist. The limit switch must have
a positive opening.
EN 14492-1 must also be taken into account when inspecting the
equipment.

Running hours counter

The running hours can be read from the running hours counter,
in order to determine when the next hoist safety check must be
carried out.

Phase sequence relay (hoists without converter)

In control units operating by three-phase current, the phase
sequence relay shuts down the system in the case of an incor­rect phase sequence and this prevents an UP / DOWN travel
direction mix-up, which could potentially disable the limit switches
and load limiting devices.

4.8 Anchoring

The hoist can be anchored with and without an adapter (see pos.
D in Fig. 2).

Anchoring without adapter: At least 2 screws with a minimum
strength class of 8.8 with self-locking nuts.

Anchoring with adapter: 2 screws with a minimum strength class
of 8.8 with self-locking nuts.

Bolts that have at least the same strength and a similar quality
for securing can be used instead of the screws.

See also ' 9.3 Assembly' on page 10.

4.9 Increasing the load bearing capacity

DANGER!

Incorrect anchoring! Incorrect usage!

Risk of being injured by falling objects!
The load on the deflection roller, rigging and the anchoring
point increases depending on the arrangement of the hoisting
gear, deflection roller and load!
– The minimum breaking strength of the deflection roller,

the rigging and the anchoring point must be four times
greater than the nominal load of the hoist in the given in­stallation situation (see Fig. 8).

The load bearing capacity of the hoist can be increased by reev­ing the rope, see Fig. 8 (F corresponds to the load bearing ca­pacity of the hoist).

Note:

Reeving the rope reduces the hoist speed.

5 Ropes

DANGER!

Incorrect rope or rope with incorrect diameter!

Using an incorrect rope leads to a danger of falling or injury
through falling objects and the risk of malfunctions!
– In order to operate safely only use original ropes author-

ized by Greifzug Hebezeugbau GmbH with the correct
rope diameter and the required design.

– If the load cannot be guided by on-site means then a low-

twist wire rope with a swivel hook or a rope swivel must
be used.

– The required rope diameter is listed Table 1 on page III.

The design is listed Table 5 on page 17.
