The Pneumatic Hilomast - BR Series

Whilst many masts in the Hilomast range can be used for Broadcast Applications, 4 standard configurations are offered to meet the particular needs of the ENG vehicle market. The BR Series of telescopic Hilomasts has a base diameter of 9" and is pneumatically operated by custom built air compressors.

These masts do not have locking collars but have special engaging torque screws fitted into each of the collars to resist the torsional loads when the masts are fully extended. The BR series of masts is for special applications where high head loads are required or where maximum directional stability is necessary.

Standard Features of the BR Series Masts
  • The use of highly accurate drawn aluminium tube ensures optimum seal performance and minimum leakage.
  • A full length keyway machined in each of the extending tubes prevents relative rotation between them, the key in this keyway will break before any damage is done to the tube section of the mast, in the event of excessive torsional load.
  • Operation over a wide temperature range -22°F - 122°F.
  • Low Pressure (14-16 p.s.i) operation, to minimise leakage and seal failure.
  • Drain holes to eject water and minimise damage to ice formation.
  • Clear anodised tubes and collars painted any colour.
  • Maganetic switch to warn of incomplete retraction.
  • Non rotating base plate and roof bearing kit.
