Overview

The loading arms can be equipped with flange connections, couplers, and various accessory options to meet specific operational requirements. For applications involving heavier connection hoses or piping, a specialized six-swivel configuration with a parallel linkage system and gas spring balancing mechanism can be incorporated to ensure smooth handling and reduced operator effort.

Built with high-quality swivel joints and an advanced spring-cylinder balancing system, these loading arms deliver exceptional maneuverability, durability, and performance across demanding industrial environments. Specialized configurations are also available for cryogenic services, including LNG transfer applications.
