10.1 Proportional HDL
In connection with the IRC-system, activation of the HDL-system is proportional,
i.e. step-less.
Example:
A heavy load is extended at max. speed at a longer out-reach by means of the
“extension out”-function.
When the loader has reached 80% of its capacity limit, the HDL is automatically
activated independent of the operator’s doings.
Now the speed of the “extension out” movement is reduced proportionally down
to 20% of the nominal working speed.
Correspondingly the working speed is increased proportionally to 100%, if the
load is retracted to a shorter reach by means of the “extension in”- function.
The example describes how the HDL-system works in connection with the
extension-function. The proportional HDL-activation functions in the same way
in connection with all other loader functions, which increase or reduce the load
moment of the loader.
When the HDL-system is activated, this is indicated on the RCL indicator panel
by the FUNC diode flashing.
10.2 Micro Operation
If the loader is to make positioning tasks, it will be possible to reduce the
working speed of the loader by means of the HDL-system.
Irrespective of the loader’s load moment, the working speed of the loader can
be reduced to approx. 20% by pushing
the red press button
on the remote
control box, thus activating the HDL.
By pushing
the red press button
once again, the HDL-system is deactivated
again. However, this implies that all control levers have been into neutral
position at the same time as the load moment is below the loader’s normal
lifting capacity limit.
