OPW Engineered Systems M-32-F — A-Frame Loader
Overview
The A Frame Loader engineered to provide safe, efficient, and reliable loading and unloading operations across a wide range of industries. Available in sizes ranging from 2″ to 4″, it can be manufactured in carbon steel, stainless steel, or aluminum to meet specific application requirements. Its unique A-frame design allows the loading arm to accommodate vehicle elevation changes and tilting during transfer operations while maintaining smooth maneuverability. When not use, the arm stores in a near-vertical position, reducing space requirements and allowing multiple loading arms to be installed in close proximity. The system can be customized with various couplings, valves, grounding systems, safety breakaway devices, and heating solutions to meet operational needs.
