Abstract: Crawler type vehicle configured for travelling in a suspended manner, exhibiting—a plurality of suspension elements configured for suspending the vehicle and configured for coupling the vehicle to a ceiling structure, —at least one first drive unit configured for circumferential motion and accommodating a first circumferential track and a second circumferential track having a different circumferential shape/contour than the first circumferential track, wherein the suspension elements are attached to the first circumferential track at predefined first longitudinal positions corresponding to a predefined raster, wherein the vehicle is configured for moving along the ceiling structure by decoupling a subset of the plurality of suspension elements from resp. coupling them into the ceiling structure when the suspension elements are guided along the two circumferential tracks by the circumferential motion.

Abstract: The present invention refers to ceiling suspension arrangements exhibiting at least one crawler type ceiling unit (10) and a ceiling structure (1) extending in at least two spatial directions (x, y) and defining at least one structural regularity (1a), wherein the crawler type ceiling unit (10) exhibits a plurality of suspension elements for suspending the ceiling unit and for coupling the crawler type ceiling unit (10) to the ceiling structure (1), wherein the crawler type ceiling unit exhibits at least two circumferential tracks, wherein the suspension elements are attached to the circumferential tracks at predefined longitudinal positions corresponding to the structural regularity (1a), wherein the circumferential tracks respectively define a specific path of circumferential motion of the respective suspension elements. Further, the present invention refers to a method of suspending the ceiling unit at a ceiling structure, especially in context with two-dimensional positioning of the ceiling unit.

Abstract: The present invention provides for a crawler type vehicle (10) configured for traveling in a suspended manner especially headlong at a structure, wherein the vehicle (10) exhibits a plurality of suspension elements configured for suspending the vehicle (10) and configured for coupling the vehicle (10) to the structure, and at least one drive unit (11, 11a, 11b, 11c) configured for circumferential driving motion and accommodating a first circumferential track and a second circumferential track having a different circumferential shape/contour than the first circumferential track. The present invention provides for a method of driving a crawler type vehicle (10) for traveling in a suspended manner especially headlong at a structure.
