Abstract
The present invention relates to a process for the assisted performance of crane movements by a crane with at least two boom elements that are movable relative to one another, whereby an auxiliary control module, after activation by the user, determines at least one target position of the boom system, determines the crane movements necessary for achieving the target position and, after active user confirmation, indirectly or directly activates the specific crane actuators for the performance of the crane movements determined by means of the crane control.
Claims18
A process for assisting movements of a luffing boom and a luffing boom extension of a crane relative to one another, comprising the steps of
- determining at least one target position of the luffing boom, if a user previously selects a supported crane function, particularly an autonomous start-up of a situation-dependent shut-down position and/or a scaffold-dependent autonomous set-up or a dismounting of a crane boom system, and/or an autonomous start-up of an installation position, preferably for assembly/dismantling of a load block,
- determining the crane movements necessary for achieving the target position of the luffing boom, and
- after active user confirmation, activating specific crane actuators for performance of the crane movements determined indirectly or directly by a crane control, to move both the luffing boom and the luffing boom extension with respect to one another.
A process for assisting movements of a luffing boom and a luffing boom extension of a crane relative to one another, comprising the steps of
- arranging the luffing boom and the luffing boom extension to be essentially horizontally extended along the ground,
- determining at least one target Position of the luffing boom,
- determining the crane movements necessary for achieving the target position of the luffing boom,
- after active user confirmation, activating specific crane actuators for performance of the crane movements determined indirectly or directly by a crane control, to move both the luffing boom and the luffing boom extension with respect to one another,
- upwardly tilting the luffing boom to form an acute angle between the luffing boom and the luffing boom extension such that a tip of the luffing boom extension remote from the luffing boom remains on the ground,
- raising the tip of the luffing boom extension off the ground, and
- adjusting the luffing boom extension to occupy a substantially horizontal position or orientation.
