Base Hinged Columns
Since Abacus developed and patented the innovative spring operated base hinged column, it has found worldwide acceptance. Robust, simple and safe to operate, it has stood the test of time.
Today’s demands for increasing operator safety and reduced maintenance costs lead to a simple choice.
The Abacus base hinged column range sets the standard.
Leadership through innovation.
BASE HINGED COLUMNS - LIGHT DUTY RANGE
The Abacus spring operated base hinged column is the best available. Anywhere. Why?
The Abacus base hinged column has been the choice of the railway industry, local authorities and industry, both in the UK and internationally, for 40 years. From experience, our customers have found that this product just goes on and on…
Fast, simple and safe to maintain. The column can be lowered in as little as 60 seconds, with absolutely no risk to the maintenance personnel.
Benefits:
- Simplicity and speed of operation
- Complete safety of operating personnel
- Access to gear only by lowering column (unless Flush Door Option is chosen)
- Vandal resistant locking screw as standard (secondary security)
- Gravity locked, can only be lowered with universal lever (standard supply)
Training
Training on all Base Hinged Columns is available either at Abacus or on site at your facility. Take a look at our
Training page for more information.
Please note
We strongly recommend that this counterbalance unit is only operated by persons who have successfully completed training carried out by an approved Abacus trainer.
Spring Counterbalance Unit

The RLS spring counterbalance unit is available in a range of colour coded options, each one
suited to take particular weights and head loads. Select from the column matrix below the correct unit for your column height and weight.
The counterbalance unit ensures complete operator safety in lowering and raising the column. Compare with alternative rope/cable operated systems which do not offer similar safety
levels in use.

RLS operating instructions for more info.
Universal Counterbalance Unit

The RLH hydraulic unit will operate all of the light duty base hinged columns (as well as the medium duty range).
This provides the advantage of having a single unit to maintain multiple column heights and headloads, either on a single site or accross a variety of sites.
