Absolute mobility is a natural demand of our time. Especially it is valid for the passengers using public means of transport. One of the conditions for this mobility is the save and barrier-free boarding into the rolling stock vehicles. The boarding systems of Pintsch Bamag are especially developed for different kinds of platforms either realized as a sliding step or as a pure gap-bridging step. Due to availability of two different drive approaches – electronic or pneumatic – it is possible to develop and to provide individual system solutions as modules. Pintsch Bamag provides Plug & Play modules that are optimized for mounting technology use in wagon building. The advantage of these modules is the simple and low-cost maintenance. The consistent implementation of customer requirements and extensive experience ensure the reliability and high availability of these systems.
