Installation

The installation precess comprises of two distinct phases !
- the ‘initial lift’, degcribed as ‘pliching’ plus traversing and then
- “final placement’.

These different phases create different stresses in the pile.

Initial Lift
The initial lift is independent of the type of final placement method used.

The pile should be positioned (via ‘lifting’ and “storing’) as close as
possible to the final destination so that pitching causas minimal dynamic
effects.

The standard pile has a lifting tubs 0.4m from the head. If the pile length
is;

-~ less than or equal to that shown in Table 3, the pile can be pitched from the
Lifting tube and traversed to the final destination.

-~ greater than that shown in Table 4, the pile will need to be pitched end then
traversed in a two-stage operation. This requires a nylon sling to be snotted
against the pile at a distance.= {0,27 x pile leagth) from the head. At the
game time a loose lifting connection is made at the lifting tube. The pile is
pitched via the nylon sling to near vertical, making sure the lifting Sube
wires are not acting, and then the pile can be lifted and traversed to the
final destination via the lifting tube. .
