10-11-29-NX14-ELB-005The NX Series of pneumatic telescopic masts (Hilomast) has a base section diameter of 152mm and is pneumatically operated by air compressor. Being heavier than the NL Series it will support larger head loads and should be considered as being the maximum size necessary for general use.

Although the NX Series can be used for portable applications it is primarily designed for vehicle installation, either bracketed to the rear, or mounted through the vehicle roof. Models NX18, NX25 and NX30 can be mounted onto the roof of a vehicle in a sliding carriage. The carriage slides rearwards and the mast is then tilted and clamped in the vertical position. All masts in this NX Series can be trailer mounted.

The NX30 has a top section diameter of 50mm for attaching the antenna. All other NX masts have a top spigot of 50mm diameter x 130mm long.

The table below only shows 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 colours and finishes. Please contact us for a quote or for more information on what we can offer.

The table shows the vertical head load that each mast will support and the maximum operational wind speed. The weight of the head load, however, is not usually the main criterion when selecting a mast. The limiting factor is usually the ‘side surface area’ of the head load.

The wind speeds shown are based on the following side surface areas:
NH Masts = 1000 sq. cm. NK = 1400 sq. cm. NL = 2000 sq. cm. NX = 3000 sq. cm. NY = 11000 sq. cm.
All dimensions are approximate.
