OPW Unsupported Boom Style Top Loading Arm is used for truck and rail top loading where long reach and variable positioning are required. Its configuration is selected around the loading geometry and transfer duty. AxFlow can help define the appropriate arrangement for a specific terminal.
The verified operating principle is that the boom geometry provides long reach and can fold back against the loading platform for compact storage. This provides the movement or control needed at the loading point. Exact configuration depends on the installed piping and connection requirements.
OPW documents that OPW lists 2, 3, 4 and 6 in sizes with carbon steel, stainless steel or aluminum construction and flanged, threaded or all-welded options. These values provide a basis for screening the application. Final selection must also consider the actual medium, pressure, temperature and site geometry.
Check reach, line size, media compatibility, vehicle type, storage envelope and required end connection. These parameters determine the suitable arm, material and connection arrangement. AxFlow can support product selection and availability checks.
AxFlow can support service and spare-parts enquiries for OPW loading equipment. The correct parts depend on the installed configuration and revision. Supplying identification details helps confirm the appropriate components before ordering.
