NOISE LEVELS
The platform power is provided by the vehicle engine driving a hydraulic pump. The unit
operates at the same noise level as the carrier vehicle.
Noise level at the operating position is approximately 70dbA.
VIBRATION
No vibration is present at the operating position that would constitute a danger to the
operator.
POWER SUPPLIES
The platform is hydraulically powered by a pump driven by a geared power take-off unit.
Electrical power for the platform is derived from the vehicle's electrical system and is
energised simultaneously with the engagement of the hydraulic power source.
SAFETY INTERLOCK
To ensure the correct sequence of platform operation, a stabiliser/boom interlock system
is fitted to achieve the following conditions:
1)
The booms cannot be operated until stabilisers are correctly deployed.
2)
The stabilisers cannot be operated unless the booms are correctly stowed.
HYDRAULIC LOCK VALVES
Each hydraulic cylinder is fitted with an integral lock valve which prevents movement in
the event of a hydraulic hose failure.
BACK-UP POWER
Back up power for all functions is provided by a DC motor driven pump unit.
The vehicle battery must be in good condition for this system to work.
MODIFICATION
The platform must not be modified in any way which changes its stability, or would
deviate from the original type approved design. A variant type approval from a notified
platform approval body is required in this case.
