W320-H Long Reach (Unsupported)

W320-H Long Reach Top Loading Arm

W320-H long reach top loading arms are designed specifically for loading/unloading compressed gas liquids and vapors from and to railcars where miss-spotting is likely i.e. when connecting with a line of coupled varying length railcar tanks. The W320-H’s longer reach and 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 a railcar.

W320-H has a 2” SS drop hose, 90° Style-30 Outboard swivel joint assembly with an option of a 2” ball valve to allow for orientation on top of the rail car as well as controlling the supply to/from the loading arm.

Outboard connections can be dry-gas coupler, hammer union or lap flange to suit the application. Breakaway couplings, remote shut down devices and purge systems can be incorporated as required.

W320-H is available in 2”, 3” x 2”, and 3” if required. Made from all carbon steel or stainless steel. Swivel joints are all split flange WL2 dual race, or WSS single race with seal material to suit the compressed gas and vapor being handled.

Available in Left Hand or Right Hand, Up-feed, Down-feed and Side-feed configurations

Typical range of vertical movement is +70° park position to -20° load position
Typical boom length is 1,500mm. Primary length is 2,000mm to 2,300mm with a 1,500mm drop hose and Style-30 Outboard swivel joint assembly. All dimensions can be changed to suit each application.
