Pile lengths grsater than 13m

Piles longer than 13m would normally need to be transported on an
‘extendable’ semi-trailer., The distance of the rear tray from the front can be
adjusted to suit the lead. Given that ;

1. The maximum overhang at the front end = 2.0m.

2, The preferred overhang is between (0,15 and 0.2 x pile length).

3. The preferred pile weight transference points aze over each of the axles or
the centre line of miltiple axles. ie the preferred locations for the pile
6upport bearers are over the axles. .

4. The waximum distance that bearers can be eplit, on the rear tray and remain

central to the axles, is 3,0m.
5, The strongest part of the pile is towards the tce end.

Then Table 2 recommends the preferred loading srrangements

Notes

1. “two point’ supports are used.
2. The pile head is placed at the front (cab) end of the truck.

3. “H' = the distance from the head of the pile to the front support bearer,
“M' = the distance from the front support bearer to the front split bearec.
-s' = the distance from the front split bearer to the rear split bearer.
“t' = the distance from the rear split bearer to the toe of the pile.

4, ‘The front support bearer is located over the front axle.

The spiit bearers are assumed to be placed either side of the rear axle
centre line, ,

For ‘S' = 0,-the rear support bearer is placed over the rear axle centre
line, . ~ :
5, These arrangements are independent of the pile strength type.
€, Truck loads are assumed to comprise of piles of the same length.

Fox truck loads with variable pile lengths, refer to Rocla.
