OPERATING INSTRUCTIONS
DAILY INSPECTION
Before leaving the depot for the day’s work, it is recommended that the following
procedure be carried out:
1)
Inspect the vehicle and platform for overall integrity, paying particular attention to
structural members, hydraulic lines, and electrical cables.
.
2)
A safe un-manned functional test of the platform should be performed using the
ground pendant control. Space permitting, the booms should be fully extended
and the slew operated through full travel to confirm function.
3)
Check that tyre pressures conform to vehicle manufacturer's specifications, as
this can affect the stability of the platform.
4)
Check the oil level in the hydraulic reservoir with the stabilisers and booms
stowed and the vehicle on level ground. Correct level is to the maximum marks
on the gauge.
5)
Check the vehicle fuel level, and that the battery and alternator are in good
condition.
6)
Carry out other routine daily checks on the vehicle as detailed in the
manufacturer’s manual.
THE OPERATING SITE
Select a site for the vehicle from where the platform will reach the required work area. A
visual inspection of the operating site shall be made before setting up the machine,
paying particular attention to: -
1)
Ability of the ground to sustain jacking loads. It may be necessary on unmetalled
roads to provide load-spreading pads in order to reduce the ground pressure. Be
aware of possible changes in ground conditions, particularly those caused by
water logging. Avoid manhole covers, drain gullies, cellar grilles etc. Typical
maximum stabiliser ground load is 1500kg.
2) Overhead
obstructions
Ensure adequate clearance around and above the platform, paying particular
attention to overhead cables,
3)
Gradients and ground flatness
Where the platform is required to operate on an incline, It is essential that:-
i)
The vehicle faces uphill, and
ii)
The booms are operated on the uphill side only.
Overtravel is provided on each stabiliser leg to enable the platform to be levelled
on cambers which slope across the vehicle. Refer to section "Stabiliser Control"
in the next section with regard to the levelling procedure.
3)
Do not operate the platform in severe weather conditions and in particular ensure
that the prevailing wind strength does not exceed 12.5 m/sec, Beaufort scale 6.
Refer to the wind strength section in "Safety Rules" for guidance
