This video is intended for loader crane operators of HIAB loader cranes and provides step-by-step instructions on how to safely extend hydraulic stabiliser extensions with Mechanical-Tilting stabiliser legs.
! NOTE
- The stabiliser leg downward movement is auto-matically stopped when pressure to the ground is sufficient. To operate the stabiliser legs further downward, move the lever once again.
- 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.
- 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.
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!
If the hydraulic stabiliser extensions are equipped with catchers, release the catchers before operating the stabiliser extensions.
1. Extend the stabiliser extension a little, until the stabiliser leg can be rotated free of the vehicle. (If manual operated stabiliser extension, unlock the handle and the catcher).
2. Unlock the stabiliser leg with the handle.
3. Use the stabiliser leg lever to tilt the stabiliser leg. Make sure that you have full control of the movement to avoid risk of crushing.
4. Lock the stabiliser leg with the handle.
5. Extend the stabiliser extension. (If manual operated stabiliser extension, lock with the handle)
6. Place the stabiliser leg on the ground.
Repeat for the stabiliser extension and leg on the other side of the vehicle
When there is an additional set of stabiliser legs: Repeat the process for the 3rd and 4th stabiliser legs.
