The NL Series of pneumatic telescopic masts (Hilomast) has a base section diameter of 127mm and is pneumatically operated by air compressor. The shorter models in this series can be easily operated by a manual footpump. Being heavier than the NK Series they will support larger head loads under more adverse weather conditions. Although these masts can be used for portable applications, they are primarily designed for vehicle installation, either bracketed to the rear, or mounted through the vehicle roof.
Models NL16 and NL22 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. Masts NL8, NL12 and NL22 have a top section diameter of 50mm for attaching the head load. Masts NL9, NL10 and NL16 have a top spigot of 50mm diameter x 130mm long.
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 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.
