In his 1898 and 1911 editions of his book 'Aerial or Wire Ropeways their
construction and management', A. J. Wallis-Tayler refers to them as posts or
standards.
In the Engineering Times special issue of April-May 1899 W. T. H. Carrington
refers to them as posts whilst J. Pearce Roe calls them trestles. R.E Commans
calls them supports and J Walwyn White of the Widnes based ropeway
manufacturer R White & Sons calls them standards.
They are called supports by William Hewitt in 'The Bleichert System of wire
rope tramways', published in 1903 in the USA. Also the USA, the Hallidie
Endless Wire Ropeway catalogue of 1902 refers throughout to towers. The
Trenton Iron Company calls them posts in 1890.
Charle F. Dwyer in the June 1975 paper, 'Aerial Tamways, Ski Lifts, and Tow -
Description and Terminology' refers to towers. 'The design of the tower
provides the basis for classification and description. If the main support
members are outside the wire ropes and the carriers pass through the
structure, it is a portal type. If the cables and the carriers pass on either side of
the main support member, it is a mast type or pylon'.
Robert A.Trennert's 2001 book, 'Riding The High Wire - Aerial Tramways In
The West', uses Tower throughout.
Having considered all the above, the genral usage in the UK trends towards
Posts and Standards, whilst in the USA the most popular usage seems to be
Towers. There is clearly no definitive standard! :-))
