2. Risks
2.1 Introduction
An analysis shows that there are three distinct risk areas for this equipment:
• Operation, lift and handling
• Repair
• Maintenace
For each risk identified, there is a short explanation and the means of limiting this risk
described. Most of the operating risks are also highlighted in other chapters in this manual.
Great emphasis is placed on the operators training to reduce the risk associated with the
operation of this equipment.
It should be stressed that, whilst the risk assessment laid out in this chapter include some
consideration of the risk of working the machine under on-site conditions, this should not
be taken as a thorough risk assessment of the site operations, as other equipment and
processes, not considered herein, may affect the overall risk profile of the operation.
2.2 Operating risk
Drop of sleepers
During transport of sleepers there is a possibility that the operator unintentionally
presses button for opening of grapple arms and thereby drops the sleepers.
• Operators of the SB60 should get thorough training in how to operate the equipment.
• All personnel are to be kept at least 5 meters from machine when operating the
equipment.
• Both hydraulic cylinders are equipped with hydraulic locks which prevents the cylinders
to open in case a hose should break in the hydraulic system.
• Personnel working with handtools or with Automaster shall always wear protective
helmet and shoes. Personnel shall not aproach the SB60 until the operator gives
visually and/or sound clear.
Clamping force is set too low and the sleepers drop down.
• Clamping force should be checked and adjusted if needed, before start, see chapter
5.6
Hydraulic leakage (personal injury)
High pressure hydraulic systems are used on this equipment. Damage or failure
of hoses and fittings may cause a high pressure jet of oil to be emitted from the
system. This could be hazardous to eyes, skin etc. Pools of leaked oil could lead to
an increased risk of slips, trips or falls. Connecting and disconnecting the supply
and return hoses to the hydraulic systems of the carrier machine carries a risk
that oil may be spilled. Hydraulic oil is frequently very hot and may cause burns
and scalds.
•
All hoses fitted to the sleeper lifter have a burst pressure in excess of four times the
specified working pressure. Regular monitoring of the dimensions of the ferrules fitted
to the hoses, and careful training of the staff employed to make up hoses ensures that
hose specifications are consistent.
• All components used in the hydraulic system are CE marked.
