W820 Long Reach (Supported)

The W820 Long Reach (supported) bottom loading/unloading arm is ideal for transferring compressed gas liquids and vapors to or from tank trucks or rail cars. The W820’s long reach enables greater flexibility with miss-spotting or obstructions from other rail car and tank truck equipment and can carry more additional equipment on the loading arm. Often used for carrying a vapor hose “piggy back” to the loading arm.

The W820’s long reach and significant miss-spot capabilities are due to a swivel boom that extends “supported” from the riser on the stand post. This provides an extra plane or rotation and allows the loading arm to track a distance along the bottom side of a rail car, or bottom side or rear of a tank truck.

Size

The W820 is available in 2”, 3” x 2”, 3 or 4” 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.
