The folded sheet steel mast shown has been developed by CU Lighting for Closed Circuit Television, CCTV sites, with restricted access for servicing after installation has been completed.

The mast has been designed for heights up to and including 47m with a maximum 3 second gust wind speed of 54 m/sec., and to 20m height for speeds up to 72 m/sec.. The mast is a duodecagon (20 sided) section to give improved aerodynamic performance.

The CCTV on its ring mounting can be lowered for maintenance by means of a self-sustaining double drum winch using a portable power tool or manually for lower heights.

This raising and lowering system has been developed by the company over a 30 year period for high mast lighting. The pulley system at the head is suitable for cables up to 20mm diameter and which are self-supporting for the
height of the mast.

The mast meets the requirements of ILE TECH 7:2000 where applicable.

Standard finish as supplied is Hot Dipped Galvanised to BS ENISO 1461.

It is normal practice to use a flanged column but an integral root can be supplied. Holding down studs are supplied complete with anchorplate for casting-in by others. A jig drilled template is supplied to locate and orientate the studs. Ground level loads will be supplied to
enable a foundation design to be carried out to suit local site conditions.
