39 WORKPIECES Component parts up to 5 t (15 m x 2.6 m x 4.1 m) PERFORMANCE DATA Product carriers: 2 x 2 x 4 single product carrier Throughput: 1 product carrier/45 min PROCESS TECHNOLOGY Heimer GmbH & Co. KG EVOBUS, GERMANY EvoBus produces shells for urban buses, cross-country buses, and coaches of the Mercedes-Benz and Setra brands in Mannheim. Each line has two coating cabins that are con- nected for simple and risk-free transport of the car bodies via a semi-automatic lifting and conveyor system. Vollert replaced the stationary lifting columns with a newly developed over- head-mounted lifting system that transports the workpieces from cabin to cabin without having to lower them. 1 A four-rope lifting gear in each cabin ensures a maximum lift of 2 m at payloads of up to 5 t 2 By means of a parallel shifting switch between the coating cabins, the empty lifting arms are first placed in an interim parking area on their way back. Moving the running rails outwards enables the workpieces to pass through before the lifting arms reach pre-defined positions 1 2 REFERENCE PROJECT
