Heavy Duty Budget Masts - Clark Masts Asia Pacific

RT SERIES MASTS - AUKA RANGE

Made in Australia, these are a rugged, cost effective mast with most of the features of our standard range of masts. Originally engineered for the mining industry, these masts have proven enduringly popular across all industries.

These masts are best suited for non-directional equipment. Whilst they are rotatable and the tube sections can be clamped, the tubes are not keyed to fix their relative bearing to each other during extension, retraction and general operation.

RT-Series masts are fitted with our trusted clamping collars that not only hold the mast erect but will also help to hold a mast’s directional bearing.

See our keyed mast range for projects that require precise directional bearing.

Short extended heights - up to 5m

The below selection of our RT models have extended heights of up to 5 metres, retracted heights as low as 1.3m, and headload capacities from 15kg to 30kg.
