Duff-Norton manufactures the broadest range of heavy duty linear actuators ranging from 2 to 50 tons. All our electric cylinder actuators are available in clevis or trunnion mounting; offset, right angle or parallel in-line mounting; with speeds up to 6.3 in/s (160 mm/s). Our heavy-duty electric actuators are used for opening and closing, tilting and pivoting, lifting and lowering, and positioning.

Heavy Duty Linear Actuators FAQs
How much weight can heavy duty linear actuators hold?
Columbus McKinnon heavy duty linear actuators range in capacities from 2,000 lbs. up to 50 tons.
Which type of actuators is more suitable for heavy load lifting?
Electric cylinder actuators are capable of lifting ultra high-capacity loads. This type of actuator is ideal because It eliminates fluids, the need for high PSI (which can be expensive), the potential for leaks and additional maintenance.
Can linear actuators be synchronized?
Tandem actuators can be used in certain applications. Small differences in motor speed may cause the actuators to get out of synchronization. Use of clutch models allows alignment when actuator is extended or retracted.
Are linear actuator limit switches pre-set?
Duff-Norton does not preset limit switches on its linear actuators. Limit switches allow you the flexibility to set the limits of travel on your actuator to fit your particular application. Easy to follow instructions are included in the installation manual, and you may phone the factory if further assistance is required. The customer is responsible for properly setting the limit switch in the unit. If the limit switches are not set, or are improperly set, the unit may be damaged during operation. In addition, limit switches may require resetting if the translating tube of your actuator is rotated manually, as this will change the limit switch setting.

Providing you take good care of your linear actuators, and you follow your manufacturer’s advice, they should be able to perform for as long as specified. These are the best tips for extending the life of your linear actuator.
Extend the life of your linear actuators
A smart actuator is an integrated actuator that includes onboard controls, communication capabilities, position control and feedback, and fault detection. This makes the actuator easy to install, use, program, and monitor, while eliminating the need for external controls.
