Engineered for Offset Loads
An offset load is any load whose center of gravity sits away from the lifting column’s central axis. Because the load is cantilevered out from the column, it generates a bending moment — measured in Newton-meters (Nm) — in addition to the vertical weight the column has to lift. Sizing a column means checking both ratings.
Every Isotech telescopic lifting column is rated for offset load capacity, and the X-Series leads the lineup at 6,000 Nm — the equivalent of supporting a 600 kg payload a full meter from the column’s centerline. That makes it the right choice for cantilevered medical platforms, wide work surfaces, and any application where the load can’t be centered directly above the column.
What Makes a Telescopic Lifting Column Different?
A telescopic lifting column is a self-contained vertical motion system built from precision-nested aluminum tubes. Unlike a standard linear drive, the telescoping design delivers a very high stroke-to-retracted-length ratio — meaning the column can travel far while remaining compact when closed.
Where others use loose-fitting tubes that introduce play and instability, Isotech’s design uses a tight-tolerance assembly with long-life guiding pads. The result is a stable, play-free lifting column that operates reliably without maintenance — even under significant offset loads.
Isotech’s electric lifting columns are available as push or pull versions to suit different mounting orientations, with optional encoder feedback for position monitoring or synchronized parallel column runs.
Tight-tolerance assembly Differentiator
Precision-fit nested tubes with long-life guiding pads eliminate play. Where others squeeze the tubes to control movement — we fit them. The result is a guiding system with no wobble or side-load drift.
Push or pull configuration
Available in push (column extends under motor force) or pull (column retracts under motor force) versions to match your mounting orientation and load requirements without redesigning the installation.
Encoder option Parallel sync
Optional integrated encoder provides position feedback for precise positioning control or synchronized parallel operation of two or more lifting columns — essential for level platforms and medical tables.
Custom stroke & load
All columns are custom made to order. Standard configurations cover strokes to 3,000 mm and loads to 12,000 N — but there are no hard stroke limits. Custom stroke lengths, load capacities, speeds, number of sections, and mounting interfaces are available on request. Contact Isotech to discuss your requirements.
Lifting Column Applications
Isotech's lifting columns serve any application that requires controlled, motorized vertical travel in a compact, self-contained package — across medical, industrial, ergonomic, and specialty markets.
Medical & Radiological Equipment
X-ray tables, CT scanners, MRI patient platforms, operating tables, and examination chairs require smooth, quiet, play-free vertical travel — often synchronized across multiple columns to keep the platform level.
Ergonomic Workstations & Office Desks
Height-adjustable desks, sit-stand platforms, and operator workstations use electric lifting columns to provide smooth, motorized height adjustment with load capacities suited for monitors, equipment, and full work surfaces.
Specialty Seating & Patient Handling
A standout feature of Isotech's telescopic lifting columns is the ability to handle large offset loads — up to 6,000 Nm on the X-Series. The column can support heavy loads mounted far from its centerline, making it ideal for cantilevered medical platforms, one-sided industrial fixtures, and imaging tables where the load is not centered directly above the column.
Industrial & Automation Equipment
Industrial workbenches, labeling stands, collaborative robots, camera stands, and assembly fixtures use telescopic lifting columns where a long stroke and stable guidance are needed in a minimal footprint.

Synchronized Multi-Column Lifting Systems
When a single lifting column isn’t enough — when you need two, three, or four columns to travel together in perfect sync — Isotech’s encoder-equipped lifting columns make it possible. The optional integrated encoder provides real-time position feedback, allowing a control system to synchronize multiple columns to within millimeters of each other throughout the full stroke.
This capability is essential for medical imaging table platforms, large adjustable work surfaces, and any application where an unlevel lift would damage the load or compromise safety. Available across A, B, F, G, and X-series telescopic lifting columns.
Telescopic Lifting Columns — Frequently Asked Questions
What is a telescopic lifting column?
A telescopic lifting column is a motorized, self-contained vertical motion system made from precision-nested aluminum tubes that extend and retract to raise and lower a load. The telescoping design provides a very high stroke-to-retracted-length ratio — far more travel than a conventional rod drive of the same closed height. Isotech’s columns use a tight-tolerance, pad-guided assembly that eliminates play and delivers stable, maintenance-free operation.
What is a lifting column used for?
A lifting column is used wherever smooth, controlled, motorized vertical motion is needed in a compact package. Common applications include medical examination tables, X-ray and radiological equipment, height-adjustable office desks, industrial workbenches, barber chairs, collaborative robots, labeling stands, and camera stands. Multiple lifting columns can be synchronized to support larger platforms such as medical tables or wide work surfaces.
What is the difference between push and pull lifting column configurations?
In a push configuration, the motor extends the column under power — the column actively pushes the load upward. In a pull configuration, the motor retracts the column under power, drawing the load downward. The choice depends on your mounting orientation and whether gravity assists the return stroke. Isotech’s team can help select the right configuration for your application.
What are electric lifting columns used for in medical equipment?
Electric lifting columns are widely used in radiological and X-ray tables, CT and MRI patient platforms, imaging system positioning arms, and examination tables. These applications require smooth, quiet, precise vertical travel with no mechanical play — often synchronized across multiple columns to keep a platform level. Isotech’s tight-tolerance assembly and optional encoder feedback make their columns a standard choice for medical OEMs.
Can telescopic lifting columns be synchronized to run in parallel?
Yes. Isotech’s encoder-equipped lifting columns provide real-time position feedback that allows a controller to synchronize two or more columns throughout their full stroke. This is essential for level platforms — medical tables, large adjustable work surfaces, and industrial fixtures — where any difference in column height would stress the structure or compromise safety. Available across A, B, F, G, and X-series columns.
Are custom stroke lengths and load capacities available?
Yes. While the standard range covers strokes to 3,000 mm and loads to 12,000 N, custom configurations are available for applications that fall outside these parameters. Isotech’s engineering team can specify custom telescoping lifting columns — including modified stroke, load capacity, speed, number of sections, and mounting interface. Contact Isotech to discuss your requirements.
