Proximity switches are mounted on the stabiliser housing. These switches signal warning lights on the remote control and main control panel to indicate the stabiliser leg is tilted beyond the point of ideal stability. This warns the operator that stability has been reduced, and therefore lifting should not take place unless it is for the restricted loads shown on the lifting diagram.
These lights may be activated when a stabiliser foot is placed into a hollow or a descending slope. In such cases it is necessary to build up the ground level by placing timber (dunnage) under the relevant stabiliser foot in order to restore full lifting capacity. |
