Using a two-part line to lift the tower is optional. If lifting the tower with a single part line, the turning block and one of
the shackles are not needed. Simply attach the thimble end of the winch cable to the shackle on the rocker plate as
shown below.
If using a two-part line to lift the tower, shackle the winch cable turning block (not supplied ) to the rocker plates using
the (2) shackles (not supplied) placed through the rocker plate hole shown in the picture below.
Your tower was supplied with a 45.7 m length of 12 mm (1/2 inch) diameter brown polypropylene rope. Cut the rope
in half to make two 22 m (75 ft.) pieces. Tie one piece from each side anchor to the top of the ginpole to stabilize the
ginpole while it is being raised.
Warning:
Failure to use the ginpole ropes could cause the ginpole to fall over to either side during the lift. Be sure to
tie the safety ropes securely to the side anchors; the ginpole is very heavy, and the safety ropes can‟t be controlled
by hand.
NOTE: The greatest load seen by the end of the ginpole (and the winch) is 907 kg (2000 lbs.). The winch
cable must be 6 mm diameter and at least 19 m (60 ft.) long so that it can reach the end of the ginpole. Size
your winch and rigging accordingly.
An extra anchor has been supplied with the 34m tower to anchor the winch.
