Base Hinged Masts
The Abacus range of base hinged masts represents over 40 years of product development.
No other company can offer the breadth and versatility provided by the 10 distinct models in our range.
Whatever your requirement, this range offers something for every application, at the same time giving you assurances which only Abacus’s engineering history can underpin.
BASE HINGED MASTS - THE WAY FORWARD & DOWN!
The Abacus range of 12m to 50m base hinged masts offers an ideal platform for floodlighting sports and large areas, as well as alternative uses such as wind turbines and telecommunications applications.
Base hinged masts are fast and simple systems to install; compared with fixed masts, large cranes are not necessary, since the hydraulic units are used to carry out the installation as well as maintenance.
Simple and safe maintenance are the key to its success; no climbing or high lifting platform is needed. Also, in comparison to the lowering crown mechanism, also offered by Abacus, the simplicity of its engineering principles ensures a virtually maintenance free life.
The HL250 and HL330 offer versatility in the heights from 10m to 20m; even at 20m the HL330 has a capacity of 8 Abacus Challenger® 1 2kW floodlights.
In addition to the HL250 and HL330, which have compact gear cabinets at the mast base conveniently mounted onto the flange plate, the new FH range of masts, up to 15m, houses up to 4 sets of control gear within its base. Two access doors provide easy access for maintenance.
Above 20m and up to 50m, Abacus offers a complete range of systems designed to take headloads for most requirements.
The Abacus base hinged masts can be found in projects around the world, given our customers’ seal of approval.
