We’re all familiar with an electric linear actuator. An electrical linear actuator is a device that converts the rotational motion of an electric motor into linear motion. The big advantage of an electrical linear actuator is that it provides clean linear motion, whether it is to push or pull or to lift or drop a specific object or a platform with tremendous accuracy in motion control.
What happens when you need a longer stroke action, that is, if you need to carry an item farther than practical with a single linear actuator? A lifting column is just the device to use for such an application. A lifting column is just another form of linear actuator that provides a longer stroke using multiple stages. The use of multiple stages allows them to expand and contract over longer length than the compact size they appear in.
The stages that are telescopically encased in a single housing allow lifting column to provide the long stroke action to horizontally or linearly carry, drop, push or pull platforms attached to them. The encased stages provide for a compact design and efficient and accurate operation in a multitude of applications in office, commercial as well as medical and diagnostic settings.
The Difference between a Lifting Column and a Linear Actuator:
A linear actuator is often a simplified application that converts rotational motion of a motor or a crank into linear motion, however, a lifting column supercharges this by deploying a linear actuator in several stages to carry the movement of the attached object or platform to double, triple or even more distance than a simple linear actuator can take it.
Application of a Lifting Column:
Since a lifting column is often required to work in tight spaces providing linear motion for static loads ranging in weight from a few to several hundred pounds and are required to provide accurate and instant start and stopping capability, they are one of the most versatile and widely used linear actuators. Their application ranges from:
- Due to a solid and stable lift, Lifting Columns are widely applied in high-end medical equipment. From patient beds to examination tables to mobility application of medical systems, lifting columns are a reliable and uncompromising essential for such applications. Other great application examples are surgery and dental chairs, x-ray equipment and other diagnostic systems. With fewer and fewer staff members to look after an ever-growing patient load and growing space shortage for equipment, medical systems now include sophisticated ergonomic solutions to allow medical staff to shift, maneuver and change location of both equipment and patients rapidly to perform a number of medical procedures quickly.
- Another great, and rapidly growing application of lifting column is in the height adjustable desk (sometimes called a Sit-Stand Desk) and ergonomic standing desk. This application, with its growing versatility and the rapidly shrinking cost, is becoming more and more popular and finding applications around the office and other commercial spaces. Both, due to its compact design, and rugged, reliable and safe operations are replacing classic pneumatic or hydraulic alternatives as well.
- Material handling is another area that has grown more efficient and robust thanks to compact and reliable workhorses of lifting platforms. Whether it is on a packing and shipping line or a light assembly line, electric actuator and lifting platforms provide a reliable, accurate and safe platform that allows efficient work without fatigue or injury.
In conclusion, lifting columns by Loctek Motion provide a reliable and durable solution, whether you are looking for ergonomic help in manufacturing environments, standing desks, conference tables, storage racks or kitchen cabinets as stand-alone lifting columns and as complete full frame systems.
