• Check that the hand chain is correctly
positioned on the operating wheel
(welding on the links facing outwards in
relation to the axis of the operating
wheel)
• Check that the operating chain is not
twisted
After positioning the corso trolley on the
beam, it is essential to check, WITH NO
LOAD on the trolley, that it moves
smoothly and freely along the whole
length of the beam.

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 location
which is dangerous for the operator, the
safety precautions laid down in the labour
regulations must be implemented to
remove all risks not covered in this

beam and pass the fixing bar through the
housing of each side plate with the
anchor point in the middle.
4. Begining with the thickest, the spacer
washers should be fitted onto the fixing
bar. Remove the side plates in turn and
replace them with appropriate spacer
washers to achieve the best adjustment
on the beam, so that the load bearing
point is in the centre of the contact area.
The person assembling the trolley should
take great care to ensure that the sides
of the wheels do not touch the central
section of the beam.
5. Distribute the remaining spacer washers
equally on the fixing bar on the outside of
each side plate and then fit the fixing
nuts.
6. Tighten the fixing nuts and fit the safety
