- The operator should always stand next to the
load lifting attachment at a safety distance
of one arm's length.
- Only use crane hooks with a safety latch.
- The suspension eye of the load lifting attach-
ment must have suffi cient space in the crane
hook and be freely articulating.
- In the case of malfunctions, stop using the
load lifting attachment immediately.
INCORRECT OPERATION
(List not complete)
- Do not exceed the rated load capacity (WLL)
of the unit.
- Only loads with dimensions within the speci-
fi ed limits for usable height and tine length
(Tab. 1) must be picked up. The picked up
load must never exceed the length of the
tines.
- When loaded and lifted, the load lifting
attachment must have an inclination of min.
5° to the rear (in the direction of the beam),
never into the opposite direction!
- Any modifi cations of the load lifting attach-
ment are prohibited.
- It is forbidden to use the load lifting attach-
ment for the transportation of persons.
- When transporting loads ensure that the load
does not swing (Fig. 1) or come into contact
with other objects.
- It is forbidden to apply lateral tensile forces
to the load lifting attachment.
- Neither the load lifting attachment nor its
parts must be used as a means for attaching
ropes, chains or belts.
- The crane fork must only be used for trans-
porting goods which are fi rmly tied on pallets
or goods which owing to their shape and size
can be directly picked up by the fork tines.
ATTENTION: When lifting the loaded crane
fork, the tips of the fork tines must never
point downwards!
- Do not allow the load lifting attachment to
fall from a large height.
- The unit must not be used in potentially
explosive atmospheres.
INSPECTION BEFORE INITIAL
OPERATION
According to national and international acci-
dent prevention and safety regulations load
lifting attachments must be inspected:
• in accordance with the risk assessment of
the operating company,
• prior to initial operation,
• before the unit is put into service again
following a shut down,
• after substantial changes,
• however, at least once per year, by a
competent person.
ATTENTION: Actual operating conditions
(e.g. operation in galvanizing facilities) can
dictate shorter inspection intervals.
Repair work may only be carried out by a
specialist workshop that uses original TIGRIP
spare parts. The inspection (mainly consisting
of a visual inspection and a function check)
must determine that all safety devices are
complete and fully operational and cover the
condition of the unit, suspension, equipment
and supporting structure with regard to dam-
age, wear, corrosion or any other alterations.
Initial operation and recurring inspections
must be documented (e.g. in the CMCO works
certifi cate of compliance).
If required, the results of inspections and ap-
propriate repairs must be verifi ed.
Paint damage should be touched up in
order to avoid corrosion. All joints and sliding
surfaces should be slightly lubricated. In the
case of heavy contamination, the unit must
be cleaned.
INSPECTIONS BEFORE STARTING
WORK
- Ensure that the surface of the fork tines
is free from grease, paint, contamination
and scale and is not coated. For operation
outdoors, make also sure that the tines are
free of snow and ice.
- Check the complete load lifting attachment
for damage, cracks or deformations.
- Check the locking pin (Fig. 5). The locking
pin fi tted on the vertical beam for adjusting
the clear height must move smoothly and
be secured against falling out by means of
the linch pin.
- The adjustable fork tines must have visibly
locked in place and be latched.
USAGE OF THE LOAD LIFTING
ATTACHMENT
Adjust the fork tines and the beam to the
required width and height in accordance with
the load to be transported and secure by
means of the latching devices.
Adjusting the width of the fork tines
- Open the latching device by turning the
spring latch (Fig. 3) through 180°.
- Adjust the tine to the required width.
- Activate the latching device by turning the
spring latch (Fig. 3) back.
ATTENTION: The spring latch must fully
lock in the frame, this must be visible.
Adjusting the height of the base frame
upper part
- Remove retaining clip (Fig. 5).
- Adapt the usable height to the height of the
load by adjusting the base frame upper part.
- Fix the base frame upper part in height with
the pin and the pin with the retaining clip.
Use of the securing chain
(mandatory for application on sites)
- Sling the securing chain included in the sup-
ply around the load on pallet and tighten it.
- Attach the loose end of the chain in the eye
on the beam provided for this purpose.
Lifting/depositing the load with adjust-
ment of the load centre of gravity
- Always lift or deposit the crane fork slowly
in order to avoid tilting of the load.
- In unloaded condition, use the last suspen-
sion eye lock at the rear.
- Slide the crane fork suspended in the sus-
pension (e.g. hook, shackle, etc.) under the
load to be picked up until the load centre of
gravity has a max. distance to the vertical
beam as is specifi ed by the load centre of
gravity distance indicated on the identity
plate for the crane fork. The suspension eye
of the crane fork must always be positioned
in the lock which is perpendicular above the
centre of gravity of the picked up load – and
it must be held there.
- The rope or the chain of the crane used must
always be vertical above the suspension
eye in order to avoid sudden movement of
the load during lifting. It may be necessary
to adjust the position of the hoist for this
purpose.
- The position of the loaded crane fork can
be checked by carefully and slowly lifting
the suspension (e.g. hook, shackle, etc.).
The load lifting attachment must be freely
suspended and have an inclination of min.
5° to the rear.
ATTENTION: The load centre of gravity
must not be shifted beyond the max. position
for the centre of gravity (see identity plate,
Tab. 1, Fig. 2).
