running features. Through constructive means an optimal aerodynamic behavior was obtained, independent of the driving direction. The pantograph WBL has a very simple drive system, which allows it to be extremely light weight and easy to maintain. Dependent on customer specifications or area of application, the pantograph can be manufactured in different materials.
Features of the WBL pantograph : -
● through integrated pneumatic suspension – low total weight
● individual suspension of carbon strips
● pan head guidance with dampened center of rotation
● hydraulic damping of fame
● easy maintenance
● optional installation of fast lowering device possible
