W300 Long Reach (Unsupported)

W300 long reach top loading arms for petroleum product are ideal for loading/unloading multi compartment tank trucks without having to move the vehicle, or for where significant miss-spotting is likely, i.e. when connecting with a line of coupled rail car tanks. The W300’s longer reach and significant miss spot capabilities are due to a “swivel boom” that extends “unsupported” from the riser on to which a fixed reach loading arm is attached. This provides an extra plane or rotation and allows the loading arm to “track” a considerable distance along the centerline of the tank truck or rail car
