Custom Hydraulic Cylinders for Metallurgical & Heavy Machinery

For the heavy truck and commercial vehicle industry, Tianjin Uranus Hydraulic Machinery Co., Ltd. designs custom hydraulic cylinders for applications such as dump truck hoists, concrete mixer drums, crane outriggers, and suspension systems. As a national high-tech enterprise with over 30 years of experience, we build cylinders that are rugged, reliable, and able to withstand the vibration, shock, and weather exposure typical of on- and off-highway vehicles. Our custom dump truck hoist cylinders are typically telescopic multi-stage designs that provide a long stroke from a short retracted length. We use high-strength steel for the stages, with induction-hardened wear bands and heavy-duty seals to prevent leakage. For a Chinese heavy truck manufacturer, we supplied custom front-mount telescopic cylinders for a 50-ton dump truck. The cylinders have 4 stages, a retracted length of 1,200 mm, and an extended length of 4,500 mm. They are equipped with a pilot-operated check valve to prevent accidental lowering. For concrete mixer drums, we provide custom hydraulic motors and cylinders for drum rotation and tilt. The tilt cylinder must hold the drum at a precise angle for pouring. We use stainless steel rods and a corrosion-resistant coating to resist cement washout. For a European mixer manufacturer, we supplied custom tilt cylinders for a 12-cubic-meter mixer. The cylinders have a bore of 100 mm and a stroke of 500 mm, and they have been in service for over 8 years. For crane outriggers, we supply custom cylinders that extend and level the crane for stability. These cylinders must be compact and powerful. We use high-pressure seals and integrated counterbalance valves. For a US-based crane manufacturer, we provided custom outrigger cylinders for a 100-ton mobile crane. The cylinders have a bore of 150 mm and a stroke of 1,000 mm, operating at 350 bar. They have achieved a mean time between failures of over 20,000 hours. Our design process for vehicle cylinders includes a durability analysis using finite element methods and validation testing on our in-house test rigs. We provide full documentation, including installation drawings and a parts manual.
