The NY Series of telescopic masts has a base section diameter
of 229mm and is pneumatically operated by custom-built air
compressors.
This range of mast is also available with locking collars. Standard NY masts
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 of masts is for
special applications where high head loads are required or where maximum
directional stability is necessary.
