This video is intended for loader crane operators of HIAB X-858 X-1058 and provides step-by-step instructions on how to fold the boom system.
1. Retract the extensions completely. Operate the first extension outward about 300mm until plate is shown.
2. Raise the first boom until Boom Deployment Assistance (BDA) allows you to operate the 2nd boom or when the angle between the horizontal and 2nd boom is more than 135 degrees.
3. Slew the crane to parking position. Check that arrows are aligned. LED for the parking control P will light blue on the User Interface [If fitted].
4. Operate the first extension inward to be sure that the extension is locked by the parking pin and the parking support.
Caution: Pay careful attention not to damage the slewing motors.
5. Lower the first boom completely. Check if the parking support rests on the slot. When the stabiliser extensions are retracted, the catcher will lock the first boom and hold the boom system in parking position.
Caution: Do these operations slowly to not damage the parking pin or the parking support.
6. Operate the 2nd boom against the support until it has contact with the support.
7. Fold the hook.
