Non-Military (Locking) Telescoping Mast

Available in both Heavy Duty and Super Heavy Duty models, non-military pneumatic locking masts offer a light weight elevation solution with a high payload capacity.  These vehicle or trailer mounted telescoping masts feature locking collars that allow the mast to remain extended indefinitely without air pressure.  Full-length keyways maintain directional azimuth and provide precise pointing accuracy.  Standard models are available in heights from 30 ft. / 8.9 m to 134 ft. / 40.8 m with payload capabilities up to 450 lbs. / 205 kg.

Non-Military Pneumatic Locking Mast

When a pneumatic mast deployment is needed for extended periods (more than a day), turn to our Heavy-Duty Locking telescopic mast. Available in six standard models up to 134 ft (40.8 m), these vehicle or trailer mounted telescoping masts feature locking collars that allow the mast to remain extended indefinitely without air pressure. Models up to 60 ft (18 m) are normally vehicle mounted so guy lines are optional, over 60 ft are field guyed and are non-rotatable.

    • 5 year commercial use warranty.
    • No maintenance required – aerospace grease provides lubrication for the life of the mast.

  • Rugged construction of high strength heat treated aluminum tubes and collars with low friction synthetic bearings for long, dependable life.
  • Two full length external keys on mast sections, and the collars have matching machined key ways which maintain directional azimuth.
  • The bumpers are designed to reduce shock on extension and retraction.
  • Locking collars allow the mast to remain extended indefinitely without air pressure.
  • All exterior aluminum surfaces are anodized and sealed for long life, and the fasteners are stainless steel for corrosion resistance.
  • Custom models can be designed and manufactured for payloads up to 600 lbs (275 kg) or for other retracted and extended heights. Consult factory.
