TOWER CONSTRUCTION
The Furlmatic 910-3 is designed to fit inside an aluminium, stainless or
steel tube with an internal diameter of 41mm with a minimum wall

A suitable mounting pole can be erected using a 6.5 metre (21 feet)
galvanised (medium) tube. The tube must be supported by a minimum of
four guy lines.
The attachment points for the guy lines to the tower should be securely
fixed to the tower.
•
The guy wires should be a minimum of 4mm in diameter.
•
The shackles should be a minimum of 5mm in diameter.
•
Rigging screws should be a minimum of 5mm in diameter.
•
All items should be galvanised or stainless steel for protection against
corrosion.

Where guy lines are looped, the loop must incorporate a thimble and be
fitted with a minimum of three rope grips.

All ground fixings must be made suitable according to the terrain.

Pivot type towers are recommended as these allow for easier installation
and lowering for access to the wind generator. Two forms of pivot tower
are suggested in Figs 2 & 3. Non-guyed pivoting towers are available, for
further details contact the dealer or manufacturer.
Note:
See the warnings section regarding the tower. It is essential that the
tower is maintained vertically to minimise lateral movement which
interferes with the effective operation of the furling tail.
