摘要:
An assembly for applying one or more materials to the rails of a railroad track includes a mounting bracket for mounting the assembly to a vehicle adapted to travel on the rails. A connecting arm is coupled to the mounting bracket, and at least one nozzle is connected to an end of the connecting arm. The nozzle arm has a hollow channel through which material flows to be applied to a rail surface. A nozzle port is in fluid communication with the nozzle channel when the nozzle arm is in an operative position. The nozzle arm is biased toward the operative position and is adapted to move away from the operative position in response to contact with an obstruction and is returned to the operative position following the contact.
