The WINDHOFF Pit Stop Concept: Get Back on Track Faster
Between 2017 and 2018, the most complex and technically sophisticated in-floor lifting system in the world was built in Olten, Switzerland.
WINDHOFF Bahn- und Anlagentechnik GmbH, Germany has obtained a contract for the design, production and delivery of 35 self-propelled On-Track Machines from SBB in Switzerland. This is the largest individual contract in the company’s history.
From spring 2017 onwards the new vehicles will be delivered successively to SBB and – according to the current scheduling – the last OTMs will be rolled out in 2021. During this time SBB is entitled to opt for the additional delivery of further vehicles of the same type.
The new machines will be used for scheduled maintenance of the infrastructure as well as trouble-shouting in case of urgent repair works. SBB had put the contract out to public tender; the final decision in favor of WINDHOFF is based on the fulfillment of the criteria «Quality» and «Efficiency». Contributing to this decision – among other things – is the innovative design of the running gear: it combines low wear and high tractive effort with extraordinary curve negotiating characteristics.
Each vehicle will be equipped with a loading platform and a loading crane. For improved access from the track bed the loading platform is partly lowered to a height of only 1.000 mm above rail-level. The high diesel engine output and the optimum applicable and efficient distribution of the driving torque onto both axles enable maximum traction forces for all upcoming vehicle applications. Even fully loaded (total weight 40 tons) a maximum travel speed of 100 km/h can be realized. Thanks to performance reserves gradients can be passed without loss of speed.
