Representation of variables in column format. The class Column refines SparVec for the representation of variables in column format. In the same way as the class Row refines the class SparVec for the representation of constraints in row format, the class Column refines SparVec for the representation of variables in column format. This class should not be confused with the class Variable for the abstract representation of variables within the framework. Again, there is a class ColVar derived from Variable having a member of type Column , but there are also other classes derived from Variable.

In architecture , an abacus from the Greek abax , slab; or French abaque , tailloir ; pl. Its chief function is to provide a large supporting surface, tending to be wider than the capital, as an abutment to receive the weight of the arch or the architrave above. The diminutive of abacus, abaculus , is used to describe small mosaic tiles, also called abaciscus or tessera , used to create ornamental floors with detailed patterns of chequers or squares in a tessellated pavement. In classical architecture , the shape of the abacus and its edge profile varies in the different classical orders. In the Greek Doric order , the abacus is a plain square slab without mouldings , supported on an echinus. In the Tuscan and Roman Doric capital, it may rest on a boltel.

The Abacus range of counterbalance units is perfectly suited to allow for flexible choices for cost efficiency for every scenario. Light duty columns can be operated with spring counterbalances as a more cost-effective solution for lower quantities, whilst the hydraulic version can also be used and is ideally suited to larger quantities especially where column sizes and headloads are mixed. Medium and Heavy duty columns are operated by hydraulic units, again with options available for the most cost-effective solution. Counterbalance units can be purchased as required or alternatively Abacus also offers the hire of units for when this is a more cost-effective solution. All persons must have completed an Abacus training course relevant to the unit this will be using prior to operation. Training can be booked via our main sales office so please get in touch. The spring unit, type RLS, is available in a range of coloured springs. Each spring type has a given capacity, based on the column height and maximum safe working load. This hydraulic unit is popular with companies who have multiple column heights and headloads on one site or over a number of sites. The advantage is that it can operate the full column range regardless of height and headload.

The York Hinge converts a fixed column into a raising and lowering column which complements our existing range of base-hinged columns. York Hinge columns are designed for use in areas that are naccessible with bulky equipment or have no room available for our standard raise and lower column to be installed. York Hinged Columns. Features Lowers the top section of the column in any set direction with no outwards swing of column sections For use on columns up to 6m Two versions available to fit 76mm and 48mm diameter shafs Headload up to 25kg at 6m using the larger unit and 15kg at 3m with the smaller unit Vandal resistant security bolt locks the hinge in place Two specially designed pins require security keys for unlocking and operation of the York Hinge Increased cabling capacity over previous designs due to external lowering device. Cast steel construction Finishing options include galvanising, painting or powder coating Maintenance free design One man operation The York Hinge itself is as strong as the column. Wind loading capacity is not compromised The York Hinge can be retrofitted to existing fixed columns, contact our team for further information. York Hinge in Action.
