In a communication support system upgrade project for a domestic ocean-going engineering vessel, the fixation and connection structure of a key cabin equipment became the focus of technical research. The equipment measures 310mm × 183mm × 200mm and weighs approximately 8kg, and is installed in the equipment compartment amidships. Due to long-term offshore operations, it must withstand continuous vibration, shock loads, and high-humidity, high-salt environments, imposing stringent requirements on the strength, corrosion resistance, and structural stability of the wire rope assemblies.
In the early stage of the project, the shipyard’s technical team compared and tested general commercial specifications following conventional practices. However, during simulated sea-state vibration tests, it was found that some models suffered minor deformation under long-term loading. Coupled with limited installation space, the wire rope assemblies were required to meet strength standards while achieving reliable fixation within restricted dimensions. The equipment dimensions of 310mm × 183mm × 200mm demanded precise matching between mounting fulcrum spacing and load distribution to avoid eccentric loading.
After extensive research and technical consultation, the project team finally contacted Xi’an Hoan Microwave Co., Ltd. After fully understanding the equipment dimensions, weight (8kg), and actual installation environment, Hoan’s technical team conducted a systematic analysis of load directions, vibration frequency ranges, and safety factors. Drawing on experience from previous marine projects, the team strongly recommended the GR series products.
During further technical verification, engineers integrated the equipment installation space and load-bearing requirements, and finally selected the GR6-142D-A model from the GR series. This model provides sufficient tensile margin while featuring a compact structure, enabling stable fixation in confined spaces. Its surface is treated with anti-corrosion technology to adapt to the high-salt marine environment, and it exhibits excellent fatigue resistance in vibration tests, meeting the requirements of long-term navigation conditions.
Actual shipboard testing showed that the equipment remained stable during continuous navigation and multi-condition operation, with no loosening or deformation, and maintained excellent signal and structural performance. The technical director of the shipyard stated that this selection not only solved the structural matching problem but also improved the reliability of the overall system.
This project fully demonstrates the professional capabilities of Xi’an Hoan Microwave Co., Ltd. in the field of wire rope assemblies. From parameter analysis to final model selection, Hoan provides not only products but also scientific and rigorous selection solutions. For marine equipment, precise selection is safety assurance, and the involvement of a professional team is an important prerequisite for project success.
