Telescopic Masts

The Pneumatic Telescopic Mast is manufactured by using heat treated high tensile aluminum alloy sections of different diameters telescoped into each other. The top aluminum sections are anodized, Bottom section is chromated and olive green powder coated (option of colour change if required) to withstand the environmental conditions.
Depending on the Antenna loads, erected and retracted height, the number of sections are designed. These sections can be easily extended vertically, using low-pressure air, to a height ranging between 3-33 meters. This low-pressure air can be supplied either by a foot pump or by an air compressor. On vehicle mounted masts the air can be drawn from available pneumatic system with additional suitable accessories. One of the special features is, the full-length key way, which prevents relative rotation between sections and enables the mast to be used for mounting directional antennas. Each section when raised to its requiredfull height needs to be clamped by locking collars. These locking collars are operated by thumbscrews. The retraction is also simple. The mast can be lowered easily, section wise, by releasing the thumbscrews and Air outlet valve.Light weight, compact and simple to operate, Smooth and effortless erection and retraction of the mast sections, Quick and easy to deploy at any place, Any number of sections can be locked, in extended or retracted position as required.
