A single rotary actuator design can perform countless tasks, such as steering, pivoting buckets, positioning booms, and many more.

Here are 6 customer applications. These examples highlight just a few ways our products have been used, but they can be adapted to virtually any industry or requirement whether you need to turn loads, pivot buckets, position booms, or steer vehicles.

1. Ride On-Floor Saw Machines (Material Handling and Construction)

USE: STEERING
Seen in airport runways and highways, rotary actuators are used in ride-on floor saws for steering to ensure precise handling and straight, accurate cuts across long work areas.

2. Refuse Collection and Bin Tippers (Waste and Recycling)

USE: BUCKET TIPPING/EMPTYING/DUMPING
In waste management, rotary actuators power tipping mechanisms used to empty refuse bins and containers. Rotary actuators can extend past the standard 135° or 180° movement to fully empty the waste bin.

3. Davits (Marine and Yacht)

USE: BOOM POSITIONING
Rotary actuators are used in yacht davits to control boom rotation and improve operator safety while moving and handling tenders.

4. Underground Drill Rigs (Mining)

USE: BOOM POSITIONING
In drill rigs used for rock excavation or blasting, rotary actuators enable full 360° arm rotation. This allows operators to position drilling tools from the ground level up to overhead surfaces without repositioning the entire machine.

5. Field Sprayers and Spreaders (Agriculture)

USE: OPENING AND FOLDING ATTACHMENTS
Actuators provide controlled rotational movement for functions such as folding booms on sprayers, adjusting spreader attachments, and positioning nozzles or sensors. Their compact design supports safe on-road transportation and efficient field adjustments.

6. Forest Fellers (Forestry)

USE: GRAPPLE POSITIONING
Forestry equipment relies on rotary actuators to move grapples and boom arms. This smooth, controlled motion improves efficiency and safety for tree removal and timber handling.


Hydraulic systems in mobile equipment need built‑in safety to prevent oil leaks and downtime when failures occur. Butterfly valves do this by isolating the large amounts of oil stored in the hydraulic tank through the closing of the pump’s suction line during a hose or component failure, helping safeguard equipment and the surrounding environment.

Here are 3 benefits of incorporating hydraulic butterfly valves:

  • Compact: Up to 77% shorter and 71% lighter than ball valves
  • Protective: Enables quick shutoff to contain oil and prevent spills
  • Practical: Allows service without draining the reservoir

When integrating butterfly valves, it is often recommended to include compensators. They help maintain pipe alignment and absorb both axial and radial stress for low-pressure applications.

Here are 3 benefits of incorporating compensators:

  • Durable: Built with reinforced high‑strength NBR for an extended service life and vibration resistance
  • Flexible: Handles pipe expansion and compression to maintain system integrity
  • Convenient: Fits SAE and DIN flanges with vulcanized seals, no extra sealing needed
