• Store and handle trolleys correctly.
• Inspect trolleys, blocks and accessories before use and before placing into storage.
• Ensure the wheel profile is suitable for the track.
• Check the trolley width is correctly set for the track.
• Ensure the track is fitted with positive end stops.
• Push rather than pull loads suspended on push/pull trolleys.
• Expose trolleys to chemicals, particularly acids, without consulting
• Force or wedge the suspension hook of blocks onto the load bar.
• Throw or drop a trolley.
• Expose a trolley directly to the elements, water spray, steam etc
without consulting the supplier.
• Use a trolley with chipped or otherwise damaged wheel flanges.
• Obliquely side load a trolley.
Selecting the Trolley
Travelling girder trolleys are available in a range of capacities with
load bars/suspension eyes to accept hook on blocks or
built into the block as an integral part. They are available with
push/pull, hand chain geared and power operated travel. Select the
trolley to be used and plan the lift taking the following into account:
Capacity and type of trolley - load bar/suspension eye or built in block
suspension arrangement - push/pull, hand geared or
power operated travel. Type of block. Track size and profile. Consult
the supplier if the trolley is to be used in areas of high
risk, exposed to the elements, water, steam etc, with hazardous
substances or subjected to extremes of temperature.
Storing and Handling Trolleys
Users will often remove blocks for storage leaving the trolley in place.
They must be suitably protected from damage and
corrosion. When removing trolleys for separate storage the following
steps should be taken:
Never return damaged trolleys to storage. They should be dry, clean and
protected from corrosion. Store trolleys in a dry, clean area protected
from damage. Operating chains, pendant power controls etc may be
removed, clearly labelled and stored separately to avoid damage.
Trolleys should not be dropped or thrown down.
Installing and Commissioning
Follow any specific installation instructions issued by the supplier.
These should be read in conjunction with the
instructions applicable to the block and should at least pay attention
to the following:
Check the runway track is level, has an even running surface and is
fitted with positive end stops which engage with the
trolley frame or wheel treads. Ensure the trolley is set to correct
width with spacers equally disposed about the centre line, that the
wheel profile is suitable for the track section and anti-tilt devices
are correctly set. If the trolley was dismantled for erection ensure the
parts are correctly re-assembled. Ensure that all bolts, nuts etc are in
place and fully tightened. If end stops were removed ensure they are
Using Trolleys Safely
The safe use of the trolley will largely be governed by the requirements
for the block with which it is to be used but should
take the following matters into account:
Do not use defective trolleys, blocks or accessories.
The trolley must be placed directly over the centre of gravity of the
load. Under no circumstances must they be obliquely side
loaded as this will cause them to tip, resulting in damage to the track
or the trolley becoming detached from the track and
falling. In the case of push/pull trolleys push rather than pull
suspended loads taking care to avoid swinging loads.
In-service Inspection and Maintenance
Maintenance may be combined with that of the block but should ensure
that the trolley is clean and that moving parts are
regularly lubricated. Keep the running surface of wheels and contact
surface of track free of any contamination including
lubricants. Regularly inspect the trolley and, in the event of the
following defects, refer the trolley to a Competent Person for thorough
examination: wear; damage to wheel treads and flanges; insecure wheels
and axle pins; loose nuts; distorted side plates, load bar or suspension
eyes; damaged or worn hand chain; damaged controls; worn, chipped drive
