Incorrect Operation; Using The Clamp - Columbus McKinnon YRC Mode D'emploi

English
INTRODUCTION
All users must read these operating instruc-
tions carefully prior to the initial operation.
These instructions are intended to acquaint
the user with the lifting tackle and enable
him to use it to the full extent of its intended
capabilities. The operating instructions contain
important information on how to handle the
lifting tackle in a safe, correct and economic
way. Acting in accordance with these instruc-
tions helps to avoid dangers, reduce repair
cost and down time and to increase the reli-
ability and lifetime of the lifting tackle. This
operating instruction must always be available
for consultation in the area where the lifting
tackle is in operation. Apart from the operat-
ing instructions and the accident prevention
act valid for the respective country and area
where the lifting tackle is being used, also the
commonly accepted regulations for safe and
professional work must be adhered to.
CORRECT OPERATION
- The capacity indicated on the product is the
maximum safe working load (W L L) that may
be attached (Tab. 1).
- Do not lift or transport loads while personnel
are in the danger zone.
- Do not allow personnel to pass under a
suspended load.
- After lifting a load it must not be left unat-
tended for a longer period of time.
- The operator must position the clamp so that
it can be operated without the clamp, lifting
slings or load posing a danger to himself or
other personnel.
- The load must be hung in the centre of the
suspension bar. Side pull is forbidden as it
damages the side plates. Always lift, lower
or pull in a straight line between suspension
point and load attachment point.
- The clamp can be used in ambient tempera-
tures between –10° C and +50° C.
For extreme temperatures outside this range
please fi rst contact the manufacturer.
- The accident prevention act and safety
regulations valid in the country of operation
are to be strictly adhered to at all times.
- If defects are found, stop using the clamp
immediately.

INCORRECT OPERATION

- Do not exceed the rated lifting capacity
(W L L) Tab. 1.
- Do not tamper with lifting tackle.
- It is forbidden to use the clamp for transport-
ing personnel.
- Welding on the clamp is strictly forbidden
(Fig. 1).
- It is forbidden to apply side-pull forces to the
clamp (Fig. 2).
- Incorrect attachment to, or incorrect loading
of the suspension bar by side pull (Fig. 3) or
by using the beam clamp as a clamping jaw
is not allowed.
- Do not let the lifting tackle fall from a great
height.
- The device may not be used in potentially
explosive zones (special designs on request).
INSPECTION BEFORE INITIAL
OPERATION
A competent person must inspect each clamp
prior to its initial operation. The inspection is
visual and functional and shall establish that
the clamp is in a safe condition resp. that
any defects found can be corrected before
operation commences.
A service engineer, a representative of the
manufacturer or the supplier, can make the
inspection although the company can assign
its own suitably trained personnel.
INSPECTIONS BEFORE STARTING WORK
Before starting work inspect the beam clamp
and all load bearing constructions every
time for visual defects. The selection and
calculation of suitable carrying beams is the
responsibility of the user.
Inspection of the beam clamp
Inspect the beam clamp and visually check
for external defects, deformations, superfi cial
cracks, wear or corrosion marks.
Inspection of beam clamp attachment
The beam clamp jaws should completely grip
the profi le so that the load is on the top of the
beam fl ange and not on the edge.

USING THE CLAMP

- The beam clamp jaws are opened wide
enough to pass over the beam profi le (Fig.
4).
- By turning the spindle in the opposite
direction, the jaws close and clasp the
beam fl ange. The beam clamp jaws must
completely grip the profi le so that the load
is on the top of the beam fl ange and not on
the edge.
- To ensure the clamp remains tightly clam-
ped and be locked against unintended
loosening, the set screw which is fi tted in
the longitudinal axis of the tensioning nut
(Fig. 5), must be tightened. A copper fl at
on the tip of the set screw prevents damage
to the spindle.
- When removing the beam clamp the set
screw has to be loosened fi rst.
- The load must be hung in the centre of the
suspension bar or the shakle.
INSPECTIONS AND SERVICE
Inspections are to be made by a competent
person at least once annually unless adverse
working conditions dictate shorter periods. The
clamp is to be inspected for damage, wear,
corrosion or other irregularities and all safety
devices have to be checked for completeness
and eff ectiveness.
Repairs may only be carried out by
specialist workshops that use original
Yale spare parts.
Inspections are instigated by the user.
