W820-L Loading Station Long Reach (Supported)

The W820-L Loading station is purpose designed for bottom transfer of compressed gas liquids and vapor transfer to/from tank trucks or rail cars. The W820-L is a complete loading/unloading station incorporating a liquid carrying arm and a vapor transfer arm mounted together on a common stand post.

Both loading/unloading arms are long reach supported boom style for maximum reach and miss-spot orientation plus both have the ability to carry additional outboard equipment such as isolation valves, breakaway couplings and dry-gas couplers.

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.
