Telescopic Masts

Telescopic Masts

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

Design & Manufacture

With years of experience in engineering telescopic masts, our designers and fabricators will look after the entire process from start to finish. Depending on the complexity of your bespoke design, using 3D modelling software we can test the theoretical stresses and strains of the individual components to ensure strength and stability


Our masts are constructed from high-quality lightweight materials such as aluminium, fibreglass, galvanised steel or carbon fibre. By using high-quality brackets, mountings, winches and cables our telescopic masts are both reliable and durable.

Bespoke Mounting Brackets

We supply a wide range of mounting brackets and fittings, so you can safely attach your headload to the mast top either permanently or for rapid deployment. If you require a bespoke mounting bracket, our design and manufacturing teams will create a custom solution.


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 (10ft) to 40m (131ft). Smaller units can be extended with a foot or hand pump with larger units requiring a compressor. Units can be supplied with accessories such as cable guides, carrying cases, hand/foot-pumps, compressors, stands and mounting brackets.


We Supply:

  • Cable guides
  • Carrying cases
  • Hand-pump or foot-pump
  • Compressors
  • Tripods
  • Trolleys
  • Pan/tilt heads
  • Mounting brackets
  • Internal cables


Supports Can Be:

  • lightweight tripod stand
  • heavy-duty field stand
  • Guyed
  • Building mounted – a wide selection of bracketry is available
  • Vehicle mounted – internal, tow hitch mounted or roof box
  • Vehicle ballasted stand – for quick deployment
  • Trailer mounted


Telescopic Lattice Masts

For permanent or semi-permanent installations where a cost-effective telescopic unit up to 30m in height is required. Constructed in 6m long sections, our triangular lattice sections are fully welded and hot dip galvanised. Supplied 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. We also have a fleet of 30m trailer masts for short or long term hire
