The catenary maintenance unit with crane and platform is a self-propelled vehicle designed for the construction and maintenance of electric railways, tramway and underground railway lines. In particular, it has been designed to string new cables and replace the old ones; it can be used as load ladder for stringing operations. The vehicle is composed by a main frame, a working platform, two axles (motor/idle axle), and a swivel frame to rotate the vehicle, a pneumatic braking system and a diesel propulsion group. The vehicles are equipped with a crane for catenary and track maintenance, or for inspections under the bridges.
