Shaft
Support structures with a polygonal cross-section.
Height: From 12 to 35 meters.
Heights equal to or exceeding than 13 meters are supplied in more than one piece that fit together.
Hot-dip galvanized according to standard UNE EN ISO 1461.
Anchorage: Anchor plate for foundation by bolts.
Note: Manufactured according to standards UNE EN-40 by means of CAD and finite elements (calculation).
Mobile crown
Consisting of a fixed part called an “upper trefoil” in galvanised steel with six polyamide pulleys where the cables slide.
There is another movable part called the “steel crown” where the floodlights are mounted at 360º.
Motor mechanism
The operation and displacement of the movable crown are made by a push-button panel that controls a portable chain hoist, which is housed in and moves on a wheeled carriage.
It is an economic mechanism, with a low maintenance cost, is also versatile and, as it is movable, it can be used on different masts.
The zinc hoist steel chain is attached to three stainless steel cables that move inside the shaft.
