Greifenberg’s gin poles are made of 3- or 6- metermodules,
which can be put one on top of the other
and assembled by means of bolts. The gin poles’ base is
made of a steel plate with pyramidal profiles that gives
the pole a stable base and prevent it from sliding to the
ground, whereas the top is equipped with anchoring
devices where 4 wind bracings, an auxiliary pulley
and the guide rail can be hooked. The spiral structure
guarantees great resistance to combined compressive
and bending stress, thus complying with safety
standards set forth by law.
