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 cor-
rectly mounted and not twisted.
2.4 Control of movements
CORSO trolleys are moved along the tra-
versing beam on the four running wheels
which are mounted on ball bearings.
Push-operated CORSO trolleys are traver-
sed 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 traver-
sed 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 traver-
sing 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 traver-
sing beam.
The trolley is traversed using four running
wheels mounted on ball bearings.
2) Main subassemblies
See page 2 and 27.
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 regu-
lar 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, clea-
ning 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 parti-
cular on the running wheels and the side
plates, must be repaired by an approved
engineer before it is used again.
It is also essential to regularly check the
condition of the traversing beam and if
necessary clean it to prevent the accumula-
tion of grease or dust which could prevent
the trolley from moving correctly.
