The Secret of the Sledge
by Liesl Clark
May 2, 1998
What took seconds to accomplish yesterday with the help of 50
people took all day today with 20. Under the direction of
Claudio Cristino, a team of 20 Rapa Nui men and the Van Tilburg team worked
together using levers and ropes to re-rig the moai transit rig
and to move the moai three meters (ten feet) to its final
raising position. First the transit rig under the moai had to
be repositioned. Without using a crane for this difficult
move, the team lifted the moai up onto logs and then slid the
rig backward underneath the moai to position the entire sledge
so it was flush with the base of the moai. Now the entire rig,
including the moai, is in a good position to be raised as one
unit to an upright position.
Jo Anne Van Tilburg
is convinced the sledge has been the secret behind her success
in transporting the moai. It will also be useful in aiding her
team as they raise it. "When this was done by Thor Heyerdahl,"
notes Van Tilburg. "He didn't use a frame (a wooden sledge).
When he lifted the statue, he damaged it by trying to lever
against the statue. Our rig enables you to lever against the
wood and not the statue. The beauty of it is that we're not
touching the statue." (See
Past Attempts.
Tomorrow, the red scoria pukao will be lashed to the top of
the moai's head at the top of the wooden sledge and then
levers and stones will be used to aid the entire group in
lifting the moai upright. No one has ever raised an Easter
Island moai upright with a pukao on top. Will the team be able
to do it?
