17 WORKPIECES Component parts up to 22 t (13 m x 4.6 m x 4.5 m) PERFORMANCE DATA Product carriers: 10 double-track product carriers Throughput: 2 product carriers/h PROCESS TECHNOLOGY SLF Oberflächentechnik GmbH BENNINGHOVEN, GERMANY Benninghoven, an asphalt mixing plant specialist, makes use of a double-track overhead system from Vollert for the overhead coating of large components. The special drive concept permits flexible overhead transport of parts weighing up to 22 t. Loading and unloading of the product carriers involves picking up workpieces either individually or together. A movable distribution manipulator then transports them over a distance of 120 m to the parallel processing stations. 1 Stationary friction wheels and distribution cranes feed the product carriers in the place of traditional chain conveyors 2 In order to permit the additional coating of special parts, the loading and unloading crane, preparation station, distribution manipulator and output stations are all designed for workpieces up to 4.6 m wide 1 1 2 REFERENCE PROJECT
