Telescopic masts

Site One is a specialist in the design, manufacture and supply of telescopic masts which are widely used in defence, security, broadcast and communications. We offer a huge range of types, push-up, pneumatic and mechanical, in heights up to 40m. They are ideal for temporary, fast installation and semi-permanent requirements but can often be ideal for some permanent uses. We can provide supports to match any masts from tripods and ballasted frames to guyed systems or trailers.

Push-up Telescopic Masts

We can supply portable push-up masts up to 12.3m for use with stands or as guyed structures. Push-up masts are constructed from aluminium, fibreglass or carbon fibre and are available in heights from 6m up to 12.3m. They are very light, weighing no more than 13kg and are available with accessories such as carrying cases, stands and guy kits.  

Pneumatic Masts

Portable pneumatic masts are constructed from aluminium alloy with heights ranging from 5m (16.5ft) to 22m (72ft). Smaller units can be extended with a footpump with larger units requiring a compressor. Units can be supplied with accessories such as cable guides, carrying cases, footpumps, compressors, stands and mounting brackets.
  • Cable guides
  • Carrying cases
  • Handpumps or footpumps
  • Compressors
  • Tripods
  • Trolleys
  • Pan/tilt heads
  • Mounting brackets
  • Internal cables
Supports can be:
  • Stands – lightweight tripods to heavy-duty field stands
  • Vehicle ballasted stand – for quick deployment
  • Guyed
  • Building mounted – a wide selection of bracketry is available
  • Vehicle mounted – internal, towhitch mounted or roof box
  • Trailer mounted
   

Telescopic triangular lattice masts

For permanent or semi-permanent installations where a cost-effective telescopic unit up to 30m in height is required. We can provide a suitable foundation and install on your site if required. The masts are formed from 6m long, fully welded, steel triangular lattice sections all hot dip galvanised. They can be supplied in two forms, either fixed vertical or tilt to horizontal when retracted. Telescoping is achieved by mechanical means using a winch operating via steel wire rope and pulleys so is very rugged and reliable. Winches are manual as standard but electric winches are an option.    

High Security ‘Sentinel’ telescopic mast

Where a stable, cost-effective mast is required for high security applications or where a pneumatic mast is not suitable, this unit is ideal. The mast is formed from square section galvanised steel and is available in heights up to 12.2m. Telescoping is achieved by mechanical means so the mechanism is rugged and reliable. Winches are manual as standard but electric drive is an option. All cables can be housed within the mast making it very secure and although the mast is very difficult to climb, anti-climb features are available as an option. This mast is available in two forms, either fixed vertical or tilt to horizontal when retracted.
