LIFTING PILE TO THE LEADER

When you have the pile near the machine and the pile is top end towards the machine
you can start lifting the pile.
• Lifting the pile from the top end.
• Check that the chains and ropes are properly attached to the pile.
• Check allowed rope stresses before start lifting the pile.
• When the top end of the pile starts moving up, lift the hammer up with the winch so
that the drive cap stays above the top of the pile.
• When the pile has been raised enough lower the hammer drive cap into the top of the
pile.
• When the pile is vertical and the bottom end is still on the ground, close the pile arms
around the pile.
• Once you locate the pile into the drive cap you can use the leader telescope to lift it
up further. This gives you the advantage that both the hammer and the pile are raised
at the same speed. The pile is then less likely to slip out of the drive cap than when
using the winches.
n WARNING
Make sure that there is nobody under the pile while you lift it. After you have located
the pile top into the drive cap you must ensure that you do not allow the top to come
out of the drive cap any more until the pile has penetrated the ground, because if you
do the pile may fall down with severe consequences.
n NOTICE
The function of the pile arms is to hold the lower end of the pile against the leader.
Never use pile arms to lift objects.
