Base-hinged masts - Grand range (18-50m)
Using a mobile twin hydraulic unit, these masts are ideal in sports, industrial and airport locations.

For large area installations, for instance port, airport and industrial sites, these masts offer numerous advantages over the lowering crown masts:



  • Ground level maintenance of mast and floodlighting system
  • No moving parts such as pulleys and cables which might cause long term maintenance issues if not carefully controlled
  • Mast painting/care done at ground level

* Assumes a Challenger® 1 type floodlight, 20Kg and 0.13m² wind area. ** Assumes a Challenger® 3 type floodlight, 16Kg and 0.20m² wind area. *** Refer to the bracket specification on your quotation for actual mast height requirement; mast may be shorter to accommodate height of the bracket, maintaining floodlight’s central mounting height.

Note:
The base-hinged masts are subject both to maximum headload capacities and wind area load limits. The floodlight quantities are to be used solely as a guide. Please check with our sales office for maximum floodlight capacities.


Technical data for columns & masts
The performance data for columns and masts gives their basic technical attributes only. The technical performance of a column or mast will be affected by local site conditions (terrain type, distance to sea, site altitude, windspeed) and the headload being carried.

Please Contact the Abacus Technical team to confirm the suitability of a column or mast for your application.
