15 PLANT TECHNOLOGY Washing cabin and adhesion water dryer, grinding station, primer and topcoat cabin, each with evaporation cabin, drying cabin with 4 stations, cooling cabin and rework station MATERIAL FLOW SYSTEM Loading and unloading crane, 5 lifters (washing, grinding, primer and topcoat, rework), friction wheel systems, rope conveyor systems for return transport of the empty product carriers 1 Loading crane with lifting crossbeam, trolley, and rotary gear 2 Lifter in 5 workstations WORKPIECES Component parts up to 20 t (4 m x 2.5 m x 1.7 m) PERFORMANCE DATA Product carriers: 20 double-track product carriers Throughput: approx. 3 product carriers/h PROCESS TECHNOLOGY Heimer GmbH & Co. KG LIEBHERR-WERK EHINGEN, GERMANY At the Liebherr factory in Ehingen, a painting plant with friction wheel and rope conveyor technology is the heart for the coating of crane ballast elements. They are used as counter- weights in mobile lattice mast and telescopic cranes that have lifting heights of up to 245 m. Depending on the product carrier, ballast ele- ments up to a weight of 20 t can be coated overhead. A loading crane supplies ballast, while an unloading crane of the same type places the finished workpieces back into a longitudinal direction every 30 minutes after coating.
