The KBK system is the perfect choice when it is about approaching any point in a room and linking workstations with one another. The static load of the hall structure is not affected cause the crane system stands on its own feet and no additional costs for bracing are incurred.
It's perfectly to be used indoor and outdoor use since its support height and crane rail length/width can be adjusted individually and it can be extended by comination of serveral fields.
