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 within the speciﬁ ed jaw capacity

must be picked up. The min. dimensions of

the load must always be complied with in

particular for load lifting attachments with

a jaw capacity that does not start with 0.

- The load must never be less than the min.

load, as otherwise the clamping force re-

quired for safe transport will not be reached.

- 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.

- Only one load may be transported at a time

with the load lifting attachment (Fig. 2).

- Always insert the load fully into the mouth

of the clamp (Fig. 4).

- The unit itself must never be used as a

means for attaching ropes, chains or belts.

- 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 load, in the

location where the load lifting attachment is

applied, is free from grease, paint, contami-

nation and scale and is not coated, so that

the clamps can make good contact with the

surface of the load. This applies in particular

for grabs with protective lining (optional).

- Check the ﬁ xed jaw and the clamping jaw

(Fig. 5) for wear and defects. Both jaws must

have clean proﬁ les.

- The protective lining (optional) must be

even and free of grease and oil. It must be

replaced when its remaining thickness is

2,5 mm or less.

- The integrated torsion spring must press

the clamping jaw against the workpiece in

unloaded condition.

- Check the complete load lifting attachment

for damage, cracks or deformations.

- The load lifting attachment must open and

close easily and freely.

- During operation of the load lifting attach-

ment it is essential to ensure that the chain

is not twisted and that it is guided in the

return sprockets.

Load lifting attachment with protective

lining up to 1.25 t (optional)

- The protective lining must be immediately

replaced when its remaining thickness is

2,5 mm or less.

- Models with protective lining may be used at

temperatures between –20° C and +60°C.

Checking the chain sling

- Chain slings must be inspected at regular

intervals in accordance with DIN 685-5.

They must in particular be replaced in the

event of wear exceeding 10% of the nominal

thickness of the chain links.

- Chain slings must be checked for outer

defects, deformations, cracks, wear and

pitting.

An elongated or worn chain must be re-

placed.

USAGE OF THE LOAD LIFTING

ATTACHMENT

ATTENTION:

The chain sling must not be

twisted and must be guided in the return
sprockets.

In order to be able to set down the load lifting
attachment onto the metal plate, pull the
clamping jaw lever in the “Open” direction.
The chain must then be unloaded. In this posi-
tion, slide the load lifting attachment onto the
load until the load has fully entered the mouth
of the clamp. By releasing the lever on the
clamping jaw, the jaw is released. The spring
pressure force ﬁ rmly presses the clamping
jaw against the load. This ensures that the
load lifting attachment remains clamped to
the load precisely as a result of the spring
pressure force also without any pulling force.
The load can now be lifted and transported.
In order to remove the load lifting attach-
ment from the load, lower the suspension
(e.g. hook, shackle, etc.) until the load lifting
attachment is completely unloaded and the
chain moves freely.
After pulling the clamping jaw lever in the
“Open” direction, the load lifting attachment
can be removed from the load.

ATTENTION:

When the pulled lever is

released, the clamping jaw lashes back ow-
ing to spring force (no lock). Therefore make
sure that there are no limbs in the area of the
clamping jaw or the chain.
