Screw Actuator Model |
|
|
|
| Because the Duff-Norton machine screw
mechanical actuator is produced in many standard models with a wide
range of capacities, there is a standard model for almost any
requirement. Models can be furnished to 250 tons capacity.
Operated manually or by means or gear motors,
machine screw actuator models can be used singly, in tandem or in
multiple arrangements. Since most capacities have a uniform
lifting speed, added economy can be realized in raising unevenly distributed
loads by operating the difference capacities in union.
Most Duff-Norton machine screw actuator models
with higher ratios are self-locking and will hold heavy loads in
position indefinitely without creep. They can be used to push,
pull, apply pressure and as linear actuators. They are furnished
with standard raises in increments of 1 inch. Depending upon size
and type of load, models are available with raises up to 20 feet. |
