tion. Any use contrary to our instructions is
dangerous and will release us from our lia-
bility as manufacturer.
Do not use the device without having read
these instructions in full and understood them.
These instructions must be kept close to
the device at all times, available to the ope-
rator and the person responsible for main-
tenance.
Follow the safety rules and ensure that they
are followed by others.
2.1 Assembling and anchoring the device
a) Trolley 250 to 5000 kg
IMPORTANT :
Before a CORSO trolley is mounted on a
traversing beam, the strength of the
materials used in the beam must be
calculated by a qualified person.
If the CORSO trolley is to be fitted in a loca-
tion which is dangerous for the operator, the
safety precautions laid down in the labour
regulations must be implemented to remo-
ve all risks not covered in this operation.
CORSO trolleys (up to 2 t) are supplied in
kit form as standard. Before they are moun-
ted on the traversing beam the subassem-
blies must be put together as follows :
• Hold the two side plates of the trolley
either side of the fixing bar, checking that
the screw threads on the fixing bar/side
plates match.
• Rotate the fixing bar continuously to
insert it on both sides into the thread pro-
vided in the side plates.
• When the threaded fixing bar has been
screwed far enough through the side
plates, attach the adjustment handle at
the end of the fixing bar (on the side with
the double drill hole).
• Turn the handle until the distance bet-
ween the running wheels is adjusted to
match the width of the traversing beam.
CAUTION :
The play between the flange of the run-
ning wheel and the edge of the lower
flange of the traversing beam must not
exceed 4 mm for load capacities of up to
2 t, and 5 mm for heavier loads.
• When the adjustment has been correctly
made, the oval part of the anchor point
must be turned to point downwards so
that it can subsequently take the suspen-
sion hook of the hoist.
• Position the copper washer in each hole
to protect the thread and tighten the two
securing screws on the fixing bar.
• Remove the adjustment handle.
Procedure for mounting the trolley on
the traversing beam
When the CORSO trolley has been assem-
bled as described above, it can then be fit-
ted onto either end of the traversing beam.
Do not forget in this case to attach or repla-
ce the end stop on the traversing beam
after fitting the trolley.
If the configuration of the traversing beam
does not allow the trolley to be fitted at the
end, the following procedure must be used :
• Hold the pre-assembled trolley assembly
beneath the beam, keeping a wide
enough gap between the running wheels
to enable the trolley to be positioned on
the beam.
• Place two running wheels on one of the
side plates in contact with the lower
flange of the traversing beam.
• Place the two wheels on the opposite
side plate in contact with the traversing
beam and turn the adjustment handle to
bring the two side plates closer together
and bring the four running wheels to rest
on the lower flange of the beam.
• Adjust the gap between the wheels as
previously indicated.
• Tighten the securing screws on the fixing
rod to prevent the assembly from moving
• Remove the adjustment handle.
For a chain-operated CORSO trolley :
• Check that the hand chain is correctly
positioned on the operating wheel (wel-
ding on the links facing outwards in rela-
tion to the axis of the operating wheel).
• Check that the operating chain is not
twisted.
