KBK classic and KBK ergo light rail rail & workstation extending cranes feature additional girders that are arranged between or beneath the crane girders. Depending on the design, they can be extended to one or both sides beyond the crane runway width. These cranes can also be used for lifting and positioning loads in almost inaccessible areas,
e.g. between pillars and columns.
Depending on the required extension length, extending cranes may be completed with KBK classic or also with KBK ergo elements.
