Helical Hydraulic Rotary Actuator

Rotary actuator for the rotation of aerial work platforms

Hydraulic rotary actuators LS2 Series, tailored for aerial work platforms, are equipped with collision-resistant large bolt mounting holes. These actuators are available in foot or clevis mounting, ensuring a flexible and compact design. They are ideal for precise control in medium load applications on aerial work platforms. These economical and efficient helical rotary actuators are also suitable for various applications, offering substantial thrust, strong impact resistance, and customizable rotation angles.

The aerial work platform-specific rotary actuators come in models with and without a balance valve. The balance valve allows the actuator to stop at a specific position in its stroke and provides holding torque. It also acts protectively against mechanical damage in cases of excessive reverse loads.

What is the difference between a rotary actuator and a linear actuator?

Linear actuators move objects in a straight line, while rotary actuators can rotate at any required angle, including in set angles (160, 180, etc. degrees) or incrementally, with a compact design and flexible installation.

What are the advantages of hydraulic rotary actuators?

Hydraulic rotary actuators are durable, providing relatively high torque, and facilitate easy rotation of equipment. They operate stably, even at lower speeds.

What are the applications of rotary actuators in industry?

The LS2 series is specially designed for aerial work platforms.
