List four possible causes of lateral instability (tipping over sideways )
Turning at speed, soft ground, poor tyre pressure, uneven loads, overloading
List at least 5 checks to the tracks and running gear during a pre operational check
check track assembly for tightness or damage, check tyre pressures, check wheels for bent rims, check
wheel nuts are secure, ensure tyres have no damage ie bulges, tears, worn thread on side walls or tread,
check for any evidence of oik leaks in axels / wheel hub
What 5 things must you ensure before taking a wheeled forward tipping dumper on the public highway?
Machine must be clean
to 7.5 t and be over 21 for dumpers over 7.5 t
State at least 4 actions the operator should take immediately after discharging the load from the skip?
Fully lower the skip before moving away from the tipping area, ensure that the direction of travel is clear
of people and other dumpers before reversing away
from the tipping area.
Explain the procedure for depending a 1 in 6 gradient with a dumper with a loaded skip?
, a loaded dumper must drive forward up a steep slope but reverse down a steep slope. The opposite
generally applies when the dumper is unladen - the machine should be reversed up the slope and driven
down the slope. It is important, however, that the operator, for each type of dumper, consults the
operator's manual before starting work.
What precautions should you implement to ensure safe loading by an excavator?
Position the dumper where the machine driver indicates ensuring that it is on level ground
