What Is a Lifting Column? Use in Hospital Beds, Tables and Chairs
A lifting column is a lifting system made of nested profiles that extends and retracts vertically. Unlike a linear actuator, it not only produces a pushing force but also works as a load-bearing element. This allows it to carry the lateral forces (moments) created by the load, often eliminating the need for an additional guide or scissor mechanism.
Telescopic design
Lifting columns usually consist of two- or three-stage telescopic profiles. The staged design keeps the column short when retracted while providing a long stroke when extended, so a wide height adjustment range can be achieved even in low-profile products.
Electric and hydraulic lifting columns
- Electric (telescopic) columns: Motor driven; precise height adjustment with a hand control or panel. They can be used in systems where several columns work together. See our telescopic lifting columns.
- Hydraulic columns: Lift by pumping and lower in a controlled way via a valve; no electricity required. Our HLC series hydraulic columns are in this category.
Where are they used?
- Hospital beds: Adjusting bed height for caregiver ergonomics and safe patient transfer.
- Treatment and examination chairs: Dental chairs, blood donation and treatment chairs.
- Examination and treatment tables.
- Height-adjustable desks and industrial workstations.
What to consider when choosing
- The load to be lifted and its position relative to the column (moment)
- Required stroke and retracted length of the column
- How many columns will work together
- Frequency of use (duty cycle) and ambient conditions
- Control method: hand control, foot control or control panel
