HDO Series Telescopic Masts
The HDO Series telescopic masts are the earliest winch-operated mast designs manufactured by Telecommunication Industries. This series is technically equivalent to traditional domestic competitor products and is intended for customers who prioritize lower acquisition cost and do not require the advanced features offered by the MD and HDN Series. Nevertheless, based on the engineering experience gained during the development of the MD and HDN Series, several design optimizations have been implemented on the HDO masts. As a result, the HDO Series offers the following improvements compared to equivalent domestic competitor products:
Supplementary Notes and Ordering Information
The weights shown in the tables indicate only the maximum mast weight and exclude the manual or electric winch, which must be added separately. For capacities above the listed values, or for customized configurations, contact the Company Technical Department. For example, order code HD0-155-7-15 refers to an HDO Series mast with a 155 mm first-tube diameter, 7 telescoping sections, and 15 m extended height. Specifications may change without notice, so request the model-specific technical annex when ordering. Masts with a gravity-descent system require at least a 15 kg external load. The mast must always be symmetrically loaded, as off-center loads can cause serious damage; consult the Technical Department for such applications. Maximum wind-exposed surface area in guyed condition is up to 1 m², and higher lifting capacity can be requested with a larger winch, which may add up to 20 kg weight.
