Preliminary Checks - Tractel Group Corso Instructions D'emploi Et D'entretien

to the under surface of the beam, but not
touching. Check that this bar does not
touch any point of the beam along which
the trolley is to travel.
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.
2.2 Anchoring the load
The hoist, winch or any other load suitable
for use with the corso trolley, must be fixed
to the trolley using the anchor point
provided.
Loads must not, under any circumstances,
be attached to any other part of the trolley.

2.3 Preliminary checks

• Check that all the parts of the trolley are
correctly assembled and tightened.
• Check that the trolley moves smoothly
and freely along the whole length of the
traversing beam.
• Check that the load capacity of the trolley
is greater than or equal to the maximum
load expected during operation.
• Check that the profile of the traversing
beam used is sufficient to safely take a
force equal to the working load limit.
• Check that the operating chain is
correctly mounted and not twisted.
2.4 Control of movements
corso trolleys are moved along the
traversing beam on the four running wheels
which are mounted on ball bearings.
Push-operated corso trolleys are traversed
by carefully pushing the load (which must
have been lifted off the ground).
The load should be moved smoothly
without any sudden movements.
Chain-operated corso trolleys are traversed
using the hand chain provided. Traversing
should be carried out smoothly and without
any sudden movements, with the load lifted
off the ground.
Never drag a load suspended from a
trolley along the ground.
The following precautions should be taken
when performing the various movements of
the trolley :
• Check that the load is off the ground.
• Never allow the load to swing.
• When moving a chain-operated trolley,
check that the hand chain cannot get
caught in a fixed obstacle.
• Avoid the corso trolley systematically
hitting the end stops fitted on the
traversing beam.
• Check that any curved radius of the
beam is compatible with the specification
of the trolley used.
IV - TECHNICAL DATA
1) Operating principle
The push-operated and chain-operated
corso traversing trolley is a lifting device. It
is designed for suspending a hoist or winch
and moving it along an I or H traversing
beam.
The trolley is traversed using four running
wheels mounted on ball bearings.
2) Main subassemblies
See page 2 and 33.
3) Name plate
corso trolleys should only be used with a
maximum load equal to the nominal load
shown on the name plate. The lifetime of
the corso trolley will depend on its regular
maintenance in accordance with the
directions and recommendations given in
these instructions.
V - MAINTENANCE AND INSPECTION
Servicing of the corso trolley consists of
monitoring that it is in good condition,
cleaning it and having it inspected
periodically (at least once a year) by a
repair engineer approved by TRACTEL
Any damage to the corso trolley, in
particular on the running wheels and the
