JZW-4 Installation & Maintenance Machine of Catenary

The machine is mainly used for construction operation, daily maintenance, rescue and other operation of overhead catenary of the railway. It can also be used as a traction car to carry out immediate repair operation of the CATENARY while being connected with other vehicles. The vehicle is a four-axle working car using hydrodynamic drive; its rated engine power is 353kW and the maximum traveling speed is 120km/h. The vehicle is mounted with a lifting and slewing operation platform able to achieve lifting and 120° slewing to left and right through double acting cylinder. It can also provide the operation space for six or seven operators at the same time on the platform. High altitude operation basket is mainly used to complete installation, removal and adjustment of upper equipment of the CATENARY during high altitude operation. High altitude operation basket is provided with automatic leveling system.
