Custom Hydraulic Cylinders for Metallurgical & Heavy Machinery

Tianjin Uranus Hydraulic Machinery Co., Ltd. provides custom hydraulic cylinders for the aircraft ground support equipment (GSE) industry, including towbars, passenger stairs, cargo loaders, and maintenance platforms. As a national intellectual property advantage enterprise with over 30 years of experience, we design cylinders that are lightweight, corrosion-resistant, and reliable under outdoor conditions. These cylinders must also meet safety standards for use around aircraft, including non-magnetic options and fire-resistant fluids. Our custom cylinders for passenger boarding stairs are typically telescopic designs that provide a long stroke in a compact retracted length. We use high-strength aluminum for the outer tubes and stainless steel for the inner tubes to reduce weight. The seal system is designed for smooth extension and retraction without binding. For a European GSE manufacturer, we supplied custom telescopic cylinders for a set of mobile stairs. The cylinders have a collapsed length of 1,200 mm and an extended length of 2,500 mm, with a lifting capacity of 1,500 kg. They are equipped with holding valves for safety. For cargo loaders, we provide custom cylinders for lifting and tilting the main deck. These cylinders must handle heavy loads (up to 10 tons) while providing smooth, controlled motion. We use high-tensile steel for the cylinder body and chrome-plated rods, with a corrosion-resistant coating. For a US-based cargo loader manufacturer, we supplied custom lift cylinders for a loader used at major airports. The cylinders have a bore of 120 mm and a stroke of 1,800 mm, and they have been in service for over 7 years with no failures. For maintenance platforms (e.g., aircraft docking systems), we supply custom cylinders for height adjustment and leveling. These cylinders often include integrated position sensors to provide feedback for automatic leveling systems. For a Chinese airport equipment supplier, we provided custom leveling cylinders for a mobile maintenance platform used on the Airbus A380. The cylinders have a stroke of 600 mm and are equipped with load-holding valves and manual overrides. Our manufacturing process for GSE cylinders includes 100 percent pressure testing, cycle testing, and visual inspection for surface finish. We also offer anodized or painted finishes to match customer specifications. For a custom cylinder for your ground support equipment and a quote, please contact us.
