1-HKS hydraulic rotary swing cylinder:

1. HKS hydraulic rotary swing cylinder is a tightly assembled hydraulic and pneumatic transmission device developed, designed, and manufactured for rotation and swing, capable of acceleration, braking, positioning, and stopping heavy objects.

2. In addition to numerous industrial application fields, HKS also provides customized solutions to construction machinery and mining industry manufacturers, providing them with internationally recognized, sturdy and efficient rotary swing cylinder connection quick change systems.

3. As a hydraulic actuator for valves, it is used in various ball valves, butterfly valves, etc., with various options available, including buffering, angle adjustment, aluminum casing, stainless steel, retaining valve, rotation angle detection, sealing, ATEX, different installation methods of flanges, different output forms of flat keys, splines, hollow shafts, etc. Various hydraulic actuators can be customized for customers.

4. Multiple reverse helical gear design, the linear motion of the piston is converted into shaft rotation through multiple helical gears, with a compact structure and high torque output. Widely used in industries such as automation, movable hydraulic devices, food, chemical, energy, power plants, municipal, special vehicles, tunnels, construction, engineering machinery, etc.

5. The quick change connection system opens up new application fields for excavators by adding two degrees of freedom of rotation and swing, supporting the quick change system. It can complete operations in limited space, quickly change different accessories, greatly improve human-machine efficiency, increase construction scope, and ensure construction safety.

6. High torque, high load, leak free, maintenance free, suitable for various harsh working conditions. Used in Norwegian AMV drilling rigs, German Putzmeister wet spraying rigs, and other drilling rod swing machines, it is also a standard configuration for domestic customers such as China Railway Construction Three Arm Drilling Trolley and Sany wet spraying manipulator.
