QTM Telescopic Mast Range

Photo: QTM MastA very simple system of masts which has been in continuous production since 1959, QT masts have found their applications in every corner of the world.

Why are they so popular?
The answer lies in the concept. Pneumatically extended, telescopic, aluminium alloy, makes the principle simple, as our competitors have found. Being complete with attached hand pump, they are a complete system in themselves. What turns simplicity into sophistication are the details, included on every mast.

Clamping collars which make erection permanent at any height, up to the maximum of the mast, independent of air pressure. Guy collars are already fixed at the most appropriate height. A 24 mm clamp collar that really clamps the spigot of the headload and releases instantly when required, every time, year after year. Also to be mentioned is the wide range of standard accessories which makes this mast series truly universal.

Normally the QT mast is not intended for applications where the headload must be turned by rotating the whole mast. For such applications the H, P or PX series should be used.

QT Masts are silent, smooth and easy to operate in every application.
