Features and Benefits
FEATURES and BENEFITS:
- Standard configurations include upright or inverted units with translating or rotating lifting screws, and top plate, threaded, or clevis ends.
- Precise Positioning - can be controlled accurately for positioning within thousandths of one inch
- Self Locking - models featuring higher gear ratios are inherently load holding as long as the actuator is not subject to vibration
- Uniform Lifting Speeds - since many actuators feature the same gear ratios different capacities can be used in the same application to lift unevenly distributed loads with uniform speeds
- Quick, Sure Operation - All actuators are designed and built to be positive acting, for accurate response to motive power
