? Pneumatic Telescopic Masts are manufactured using heat treated high tensile aluminium alloy sections of different diameters telescoped into each other.
? The number of sections vary depending on the erected height , shut height and head load. The mast can be erected easily using low pressure air either by a foot pump or air compressor.
? As the sections extend vertically, they are locked using locking collars which are provided at the top of each section.
? Operating these collars is easy through Yoke keys. once these collars are locked properly they allow the mast sections to remain in extended position. A full length key-way is provided in each of the section to prevent relative rotation between the sections. In order to withstand heavy wind loads, robust mast sections are also anchored with guy ropes at different levels.
