OPW A-Frame Loader is used for tank-truck bottom loading and selected top loading or unloading duties, including LPG service when correctly configured. 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 A-frame geometry provides flexible reach, adjusts for vehicle elevation and tilt, and stores upright in a compact near-vertical envelope. 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 to 4 in sizes, carbon steel, stainless steel or aluminum construction, and flanged, threaded or all-welded configurations. These values provide a basis for screening the application. Final selection must also consider the actual medium, pressure, temperature and site geometry.
Check product, line size, reach, riser height, material, connection type and whether LPG or another special service is required. 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.
