Mastering HIAB Tiltable Stabiliser extension

This video is intended for loader crane operators and provides step-by-step instructions on how to extend the tiltable stabiliser.

Starting the safety system
The operating levers must be in the neutral position before start up. To start the safety system, press the On/Off button. The LED above the button lights up. The system will check itself. (2-4 seconds) The warning lamps on the stabiliser legs light up.

Extend stabiliser extensions and set stabiliser legs
To ensure the full crane capacity, all the stabiliser extensions and legs must be fully extended and set to the ground without lifting the wheels off the ground.

Note: For cranes with VSL the stabiliser leg downward movement is automatically stopped at a pre-given force level. To exceed this pre-given force level, operate the stabiliser leg down once again.

Danger: Take care not to lower the stabiliser leg to your foot.
Check that the support plates do not bend or sink into the ground!
Always ensure that the stabiliser legs and stabiliser extensions are in working position and securely locked.

Operating the stabiliser system
When you are operating the stabiliser extensions: Make sure that you have a full view of the stabiliser extensions. Do not stand in front of hydraulically operated stabiliser extensions.

From the controller:
• Press the button on the controller to select the programmed menu for stabiliser extensions and legs.
• On the side where the stabiliser extensions are to be operated outwards, press the button to confirm the view. The stabiliser legs can be driven up and down regardless of the side.

As soon as the button for the stabiliser extensions has been pressed the LED for the activated stabiliser leg will light green and the stability sector LEDs will indicate crane capacity in six different sectors due to stability, given that the stabiliser leg is to be set in the present position. The stability sector indication will change in accordance with the stabiliser leg being operated in either direction.

Repeat for the stabiliser extension and leg on the other side of the vehicle
When there is an additional set of stabiliser legs [option]: Repeat the process for the 3rd and 4th stabiliser legs.

To determine the inclination of the truck, check the spirit level on the crane. When the bubble is in the middle of the gauge, the crane is in horizontal position. When the bubble is between the two circles, the crane inclination is between 0° and 5°.
If the slope exceeds the permitted inclination, unintentional crane movements can occur.
