QHLY Series Steel Hydraulic Hoist Cylinder

Heavy Duty Piston Cylinder for Gate Hoist and Industrial Oil Applications

The QHLY series hydraulic hoist cylinder is a heavy-duty piston-type cylinder designed for reliable linear actuation in demanding industrial environments. With a generous 16-meter stroke and robust steel body, it is specifically engineered for water conservancy projects, oil industry operations, and mechanical equipment that require high force and precise positioning.

Manufactured by Changzhou Hydraulic Complete Equipment Co., Ltd, this cylinder supports maximum reliability with features such as IP67 sealing (as required in marine and metallurgical environments) and corrosion resistance for harsh outdoor conditions. It is part of our complete line of hydraulic hoist equipment, backed by over 35 years of experience and ISO 9001 quality assurance.

Materials and Structure

The cylinder is constructed with a steel body available in carbon steel, alloy steel, or stainless steel, providing strength and corrosion resistance depending on the choice. The piston-type structure ensures efficient linear motion and high force transmission. Optional surface treatments such as ceramic coating and HVOF rod are available for enhanced wear and corrosion protection in harsh environments.

Applications

Water conservancy and hydropower projects (hydraulic hoists for gates and valves)
Oil industry (valve actuation, platform equipment)
Marine and offshore equipment (cranes, winches, hatch covers)
Mechanical equipment and vehicles
Metallurgical industry (steelmaking, continuous casting)
Energy and port facilities

Customization

We offer non-standard customization of hydraulic cylinders to meet specific engineering requirements. Custom options include:

Custom strokes and dimensions
Special materials and coatings (e.g., ceramic coating, HVOF)
Integrated sensors or position feedback
Customized mounting interfaces
Enhanced sealing for extreme environments

Case Study

In a recent project for a pumped storage power station (China), we supplied hydraulic hoist cylinders for tailrace emergency gate control. The core hydraulic hoist achieved a holding force of 5000 kN, enabling quick and smooth closure of the gate under emergency conditions. The gate slot cover plate was manufactured with a flatness error controlled within 0.05 mm per square meter, ensuring precise fit and reliable operation. This demonstrates our capability in high-stakes water conservancy applications.
