Actuators for Ergonomic Moving and Lifting Equipment

Ergonomic manipulators (also know as ergo arms, articulating arms, articulating jib arms, and lift assist devices) are lifting assistance devices used to help workers lift, maneuver, and place items that are impossible to safely lift themselves.

Ergonomic lift assist devices increase productivity while offering an economic solution to material handling needs. They create a better way to work providing a safe and healthy workplace for employees, while increasing efficiency and productivity at the same time.

The Kinetrol vane actuator is an ideal pneumatic drive for industrial ergonomic manipulators due to:

• Compact size
• Powerful
• Wide range of torque outputs
• Exceptionally smooth control

What Is a Vane Actuator?

Vane actuators use pneumatic or hydraulic power to open, close, or modulate quarter-turn valves, dampers, louvers, as well as for precise movement of ergonomic lifting equipment.

Linear motion gas/hydraulic cylinder or piston actuators use gears to convert linear to rotary motion. Vane actuators employ a rigid vane inside a sealed chamber that is connected directly to the drive shaft at one end with no gears. The result is much smoother rotary movement and greater cycle life.

Vane actuators operate by introducing a fluid or gas to either side of it's enclosure through inlet/outlet ports, creating the force required for movement. Advanced vane actuators utilize double sided vanes that allow for pressurization of both sides, allowing for bi-directional movement. The vane itself provides an arc movement in the far side (opposite the shaft) of the actuator, translating rotary movement back to its integrated shaft.

The vane actuator shaft is designed to connect directly to a device (valve, damper, ergo mechanism) for the transfer of movement. In advanced design vane actuators, the shaft is completely sealed from the pressurized side of the vane via “lip seals” which act to prevent the loss of air/gas/oil through shaft seals or bearings. With the help of spring steel supports, the lip seals are kept in constant contact with the inner surface of the chamber wall at all times during rotation. A side benefit of lip seals are the self-cleaning or sweeping action they provide to the inside chamber surfaces.

Since the double-sealed vane separates the vane actuator chamber in two sides, movement in either direction can be changed merely by creating a pressure differential on either side of the vane. Inlet/outlet ports allow for the pressurization and de-pressurization for either side. As gas or fluid is introduced to one side, the vane is forced away, toward the opposite side. By reversing the pressure and vent ports, and pressurizing the opposite chamber, the actuator moves in the opposite direction.

When vane actuators use only gas or fluid as their source for movement in both directions, they are referred to as “double acting”. When an optional spring is used to provide the power in one direction (open or close) they are referred to as “spring return”.

Vane Actuator Compact Size, Power, and Smooth Control Perfect for Ergo Arms

An industrial ergonomic manipulator (also know as ergo arms, articulating arms, articulating jib arms, and lift assist devices) are lifting assistance devices used to help workers lift, maneuver, and place items that are impossible to safely lift themselves. Factors that usually determine the need for an “ergo arm” are item size, weight, or temperature. Different from vertical lifting equipment such as cranes and hoists, ergonomic manipulators can control the pitch, roll or spin of an items for proper placement.

The Kinetrol vane actuator is an ideal pneumatic drive for industrial ergonomic manipulators because of their compact size, powerful torque output, and exceptionally smooth control.
