CHECKING THE JIB
1.
Support the Access Platform on the outriggers so that the wheels are about 100
mm off the ground.
2.
The platform must be empty.
3. Lift the boom off the transport support and turn the boom about 10 degrees to the
left. Lower the boom to horizontal position. Lower the jib to vertical position. The angle
between the jib and the boom is 90º±5º.
4.
Extend the telescope boom continuously until the load control stops the extension
movement.
5.
Lift the jib boom upwards. The jib boom must rise. If the rib boom rises, the Access
Platform must not be used. Check the operation of valves Y12 and Y13 in the platform.
CHECKING THE BACKUP SAFETY LIMIT FOR LOAD CONTROL
- Parallel with the load control, adjusted further on, i.e. for a larger lifting radius, there
is an electric safety limit switch which interrupts all movements. It works when the actual
load control is misadjusted or out of order. In normal conditions, the electrical backup
safety limit does not work. If the backup limit switch is activated, the boom must be
retracted to its normal range using the emergency lowering system, as this backup limit
switches off the Diesel engine, and it will not start again as long as the backup limit is
working. Even if the backup limit switch is activated, there is no danger of the Access
Platform tipping over.
