Company Information Global Player – Worldwide Presence Our company was founded in Luxembourg in 1912 by engineer August Stemmann. At that time, we were already involved with producing power supplies for cranes at steel and smelting works as well as for other mobile machines. Slip ring assemblies for rotating machines and pantograph systems for railway vehicles were added later on. We have been part of the Fandstan Electric Group since 1984 – a private holding company with subsidiaries in Great Britain, the Netherlands, Poland, France, China, India, Taiwan, the USA and Australia. The...

Railway Technology Systems – Suburban Rail, Metro and Rapid Transit Railways Third Rail Shoegears We are specialised in customised innovative solutions in the field of third rail shoegears for suburban rail, metros and rapid transit rail. THIRD RAIL SHOEGEAR SYSTEMS Top-Running-System Bottom-Running-System Thanks to its large cross-section, the third rail Side-Running-System can transmit high current densities. It is always used when an overhead wire for roof-mounted pantographs cannot or should not be installed. Our third rail shoegears are in everyday use in local rail networks of the big...

Railway Technology Systems – Suburban Rail, Metro and Rapid Transit Systems for Third Rail Shoegears Pneumatic systems are powered by compressed air. The deployment and retraction to the conductor rail and attachment of the current collector is controlled or initiated centrally from the driver’s cabin. Inductive or mechanical proximity switches are used for detecting the shoe position. Pneumatic systems can also be actuated with insulated hand levers using the emergency function. Pneumatic system Mechanical systems are operated manually. The deployment and retraction of the current...

Railway Technology Systems – Suburban Rail, Metro and Rapid Transit Components for Third Rail Shoegears Supplementary to our third rail shoegear, we also supply optional accessories and safety components that are required, depending on the specification. SYSTEM COMPONENTS Short-circuit terminals Fuse box Connection terminals Hand lever Protective covers Pneumatic short-circuit terminals are safety devices that are operated from the driver’s cabin (remote-controlled). They can generate a short-circuit between current-carrying rails and the running rail, as a result of which the respective...

Railway Technology Systems – Suburban Rail, Metro and Rapid Transit Components for Third Rail Shoegears The connection terminal joins the cable connection of the current collector within the circuit of the vehicle. It is designed according to customer requirements and can also accommodate connections for a fuse box or short circuiter. The insulated connection to the bogie frame is provided by means of standard insulators. Covering hoods prevent direct contact with electrified parts and increase the safety of the maintenance personnel. The connection terminal can also be used as a Stinger...

Railway Technology Systems – Suburban Rail Roof-Mounted Pantograph for Suburban Rail To meet the specifications and wishes of our customers, we manufacture powerful suburban rail roof-mounted pantographs according to a new, efficiency-oriented design concept - fast, well priced and low maintenance. That is also a reason why the Fb product family is today among the most frequently used pantographs in suburban rail. The rating design for DC networks can be changed on a project-specific basis and provides options for individual modification according to the prevailing usage and operation...

Railway Technology Systems – Suburban Rail Constructional Core Components of the Fb Pantographs The Fb pantograph is supported on four pin insulators made of cast resin. For fastening on the base frame of the pantograph, or on the roof of the wagon, the insulators have correspondingly moulded inserted nuts on both sides. The base frame consists of welded rectangular tubes and supports the suspension braces for the lower arm struts, the drive, etc. OPTIONAL FITTINGS OF THE Fb-PANTOGRAPHS Mechanical or compressed gas-operated Automatic Dropping Device (ADD) Inductive proximity switch for...

Railway Technology Systems – Heavy Rail Roof-Mounted Pantographs for Heavy Rail Our DSA roof-mounted pantographs have been developed for high performance in heavy rail systems (Heavy Rail Vehicles). Their design concept, with high-strength, lightweight and innovative engineering has proven itself worldwide under the most difficult conditions. The basic type of the DSA product family is based on a modular structure concept. The core components and modules like the base frame, raising drive, the lower and upper arm as well as the collector head and the contact strip have been optimised in...
