Pneumatic Telescopic Mast – NY Series
The NY-Series of telescopic Hilomasts has a base section diameter of 9.3 inches and is pneumatically operated by custom-built air compressors. These masts do not have standard locking collars. Locking collars are available at an additional cost. NY-Series have special engaging screws, fitted into each of the main collars, to resist the torsional loads when the masts are fully extended.
The NY-Series masts are suited for special applications where high head loads are required or where maximum directional stability is necessary. There is a wide use of applications for this series, typical uses could be:
- Mounting video cameras fitted with telephoto lenses
- Microwave dish antennas for electronic news gathering/outside broadcast
- Direction sensitive antennas or devices.
- NY12 and NY14 = 4300kg cms
- NY7 and NY21 = 5200kg cms
- NY10 and NY18 = 5800kg cms
All NY masts have a horizontal flange of 6.1 inches diameter at the top for mounting antennas etc. This flange can be drilled to suit customer requirements.
Please request a copy of our new Hilomast brochure for further details on other competitive products we specialize in.
The table of masts below is only a small selection of possible mast configurations. Due to the modular design of all Hilomast Pneumatic masts we are able to offer masts in custom sizes, with or without locking collars, and in various colors and finishes. Please contact a member of the sales team for a friendly chat about your requirements.

The table shows the vertical head load that each mast will support and the maximum operational wind speed. The weight of the antenna, however, is not usually the main criterion when selecting a mast. The limiting factor is usually the ‘side surface area’ of the antenna.
The wind speeds shown are based on the following side surface areas:
NH Masts = 1 ft². NK = 1.5 ft². NL = 2.1 ft². NX = 3.2 ft². NY = 11.8 ft².
