Applications of Hydraulic Rotary Actuators

Hydraulic rotary actuators, also known as hydraulic rotary motors or hydraulic swing actuators, are devices that convert hydraulic energy into rotational mechanical energy. With their compact structure and high torque output, they have gained increasing popularity among customers. Below, we introduce their applications in various industries.

Construction Machinery

Excavators: Hydraulic rotary actuators are used to drive the rotation of components such as buckets and booms, enabling digging, swinging, and other operations. For example, in excavation tasks, rotary actuators control the bucket’s angle and direction for more precise digging.

Cranes: In large-tonnage cranes, rotary actuators facilitate the rotation of the cab, providing operators with better visibility.

Loaders: Rotary actuators help loaders achieve the required rotation of the bucket, significantly reducing manual labor and improving efficiency.

Mining Equipment

Drilling Rigs: During drilling operations, rotary actuators precisely control the rotation of drill arms to ensure accurate drilling angles and positions.

Mining Conveyors: Hydraulic rotary actuators drive conveyor rollers or sprockets, ensuring the smooth transportation of minerals and coal. Their powerful torque and precise control contribute to stable conveyor operation.

Agricultural Machinery

Tractors: Rotary actuators are used in attachment mechanisms or cabs to adjust the working angle of implements and improve operator comfort and efficiency.

Combine Harvesters: In components such as headers and conveyors, rotary actuators enable rotation and oscillation, allowing the machine to adapt to different crops and harvesting conditions.

Special Vehicles

Fire Trucks: Rotary actuators provide reliable power for equipment like ladders and fire cannons, ensuring firefighters can quickly and accurately tackle fires.

Sanitation Vehicles: Devices such as garbage compactors and loading mechanisms use rotary actuators for rotation and oscillation, enhancing garbage compression and unloading efficiency.

Metallurgical Equipment

Rolling Mills: Rotary actuators precisely control the rotation speed and angle of rolls, ensuring high-quality steel processing.

Converters: In steelmaking, converters rotate to evenly mix molten steel and facilitate heating, powered by robust hydraulic rotary actuators.

Hydraulic Equipment

Gate Operators: Rotary actuators control the smooth and precise opening and closing of hydraulic gates, effectively regulating water flow.

Water Turbines: To maximize efficiency, turbine blades adjust to water flow changes using rotary actuators for accurate angle control.

Machine Tools

Machining Centers: Rotary actuators enable quick and precise rotation and positioning in components like tool magazines and worktables, enhancing machining accuracy and productivity.

Milling Machines: Worktables or milling heads use rotary actuators for stable rotational power, allowing for multi-angle processing of workpieces.

Robotics

Industrial Robots: Many industrial and special-purpose robots use hydraulic rotary actuators as joint drivers for rotational movements. For instance, actuators drive the arm joints of material-handling robots and the welding mechanisms in robotic welders.
