TM Series

The NEW Clark Masts TM Series range of super heavy duty pneumatic telescopic masts have a base tube diameter of 9 inches and a maximum of nine telescopic sections. TM masts offer a very wide range of models and headload ranges up to 500kg and extended heights from 2m to 34m. The ultimate telescoping Clark Mast.  TM Series are an ideal solution where a high degree of stability is required.

Each telescoping mast section is keyed to prevent relative rotation to the next tube allowing the complete mast to be rotated from the ground with ease if directional headloads are being deployed. TM masts can be fitted with locking collars depending on the type of application and with rotating or non rotating bases.

Bearing surfaces are fitted with nylon and PTFE to guarantee smooth and effortless extension and retraction in the most demanding climatic conditions. All TM masts are qualified to MIL STD 810F. As each section is extended, an automatic collet locking system provides complete rigidity when the mast is fully extended. Double Supertork is fitted as standard giving torsional stability of +/- 1.5 degrees. For enhanced torsional stability, our bespoke Triple Supertork System gives down to 0.1 degrees of stability, dependant upon mast model/size.

TM masts can be fitted to vehicles, shelters,field mounted, roof trolley mounted or trailer mounted on our 804 Series trailers

TM Series masts are supplied with special heavy duty clamping (locking) collars which are a separate part to the mast so can be added as a retrofit item. They are supplied as standard with large T handles or are also available with hexagonal fittings as shown in the picture above.


Accessories can be painted to match the mast
