Pantograph and Carbon Strip

•It is an imperative prerequisite for the safe and economic operation of both Light and Heavy Rail transit vehicles to assure uninterrupted and complete current collection from the caterary or the power rail. Schunk is proud to design and manufacture complete pantographs, carbon strips and carbon inserts for trolley pole systems.

Today our products have received industry recognition and good reputation with many European and global transit companies.

Earth Return Current Unit

•The working currents of electric ecomotives and traction and passenger vehicles are fed via the axle shaft and wheels to the rails and thus buck to the energy source. It is essential to equip Return current-/Grounding-/Earthing contacts to provide a good electrical connection for preventing current flow to roller bearings.

Carbon Brush and Holders for Traction Use

•Due to above-average level of external mechanical vibration and shock, traction brush holders are distinguished from those for stationary machines by substantially more rigid construction and application orientated pressure equipment. Also, carbon brushes for this field request higher performance requirements. Schunk ranks internationally amongst the leading manufacturers of carbon brushes and brush holders.

Schunk Measurement System

•Schunk Measurement System is a very good measuring equipment to measure the working performance data of the running pantograph by several testings such as Caterary Testing (CTS), Aerodynamic Behaviour and Adjustments (ATS), and Dynamic Behaviour (DTS). This system is based on the data acquistion board DAP3000-212CPU and with some required tranceducers, accelerometers, detector etc. for data collecting.
