Unsupported Boom Bottom Loader
Unsupported Boom Bottom Loader
Designed to provide flexible long-range operation, the heavy-duty unsupported boom type bottom loader configuration is both reliable and easy to use. A minimum of five swivel planes of rotation offer complete flexibility in making tight connections for loading and unloading rail cars and tank trucks. The outboard swivel and arm adjusts for any changes in elevation or tilting that may result as the vehicle is loaded or unloaded. The unsupported boom type loader is extremely versatile and many variations are possible. It can be equipped with dry disconnect coupler, union, quick coupling, or other customer specified end fitting to make connections on the side, at the rear, or underneath the vehicle. The intermediate swivel is often 2” – 6” sizes available inverted to achieve the low profile and clearances needed to connect to the underside of a rail car.
Typically installed at or near ground level, arms of varying lengths can be mounted on staggered risers to achieve crossover and neat compact storage of multiple arms in a confined space.

Accessories
Heating – Loading Arms can be fully or partially jacketed for efficient handling of asphalt, molten sulfur, waxes, resins and other products that are highly viscous or tend to solidify at ambient temperatures. Click here for more information on OPW Heated Loading Solutions.
Loading Arm Insulation – OPW can provide a Custom Insulation Package designed specifically for your loading arm. Unlike field-applied insulation, these packages are completely removable and reusable, making them the ideal solution for loading arm use. Click here to view Loading Arm Insulation Specifications.
Grounding/Bonding – Suggested for many top/splash loading applications. Available as an option on all Loading Arm designs.
Electronic Ground Verification
The Civacon model 8030 Ground Verification Monitor is compatible with today’s transport ground systems. The monitor is equipped to provide a permissive signal to allow load rack operation and, if ground is lost, to indicate a non-permissive signal and shut down the loading operation.
Protects your equipment, piping and personnel in the event of an unintended pull-away. A consideration whenever you are making a tight connection to a truck or railcar.
