SRS Road/Rail Vehicle Type LRB 10-3.
Type LRB 10-3
The vehicle is built on a standard Volvo FL 614 chassis, or similar. The LRB is specially designed for maintenance, repair and inspection of overhead line systems. It is equipped with the patented SRS Rail Travelling System, which allows the vehicle to travel on road as well as on track. With the system you can enter and leave the track at any railroad crossing within a few minutes and with no disturbance of the traffic on adjacent track.
SRS RAIL TRAVELLING SYSTEM
Consists of a driving bogie at rear and guide/rail wheels in front. The forward rail wheels are mounted in front of the chassis’ regular front axle and the bogie is placed at the rear end of the chassis. The device is elastically suspended and shock absorbed by conical rubber cushions. Lowering and lifting of the rail travelling device is hydraulically operated. All rail wheel axles are equipped with hydraulic two-circuit disc brake systems. The rail wheels have a diameter of 440 mm. The braking distance from a speed of 70 km/h to stop in a gradient of 10‰ downwards is less than 200 m.
The hydraulic system consists in principle of two circuits: hydro-static transmission circuit for driving the rail wheel bogie on track and the manoeuvring circuit for the lift and lowering/lifting of the rail wheels. The hydrostatic transmission consists of a directly driven variable axial piston pump, controlled by an electro-hydraulic servo, feeding the hydraulic motor in the bogie.Manoeuvring device for the lift and lowering/lifting of the rail wheels, consists of a fixed axial piston pump powered by the P.T.O. on the gear box of the chassis.
The LRB vehicle is also equipped with a special 3-boom lift for overhead line works,designed to withstand strong horizontal forces, which could appear when pulling contact wires etc. The working platform can be exposed to a maximum horizontal force of 2000 N at an outreach of 4 m up to a height of 7.2 m over the top of the rail. Above 7.2 m the max allowed horizontal force is 1000 N.
