W400 Long Reach (Supported)

W400 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 W400’s longer reach and significant miss-spot capabilities are due to a “supported swivel boom” that extends from the riser on the stand post and to which a fixed reach loading arm is attached. The supported boom allows for even longer range and/or superior weight carrying capacity than the W300 “unsupported” model. The supported boom provides an extra plane of rotation and allows the loading arm to “track” a considerable distance along the centerline of the tank truck or rail car
