Hello...what's going on here then? Sil van Wanrooij has kindly sent me these images showing as rather neat peice of reversing of a extra-long low loader in Holland. Sil says they taken by Marjan Varekamp ("Who took them on my request") so credits all round from Biglorryblog...
Sil explains: "The truck was 5-axle Volvo tractor with a 4-axle low loader carrying a 60-tonne screw piling machine. The problem was that he had to back down a 2-line dike to a typical Dutch farmhouse. When you watch this in reality you see what a magnificent machine this combination really is!" Biglorryblog is not about argue...and click through here for more...
Sil adds: "The 'hill' up to the dike was rather steep. 90-tonnes gross? No problem.
The dike was blocked by escort vehicle."
"What do you mean tight parking? Hope the pictures are of use to you best regards Silvester from Holland (I used to work for Mammoet ferry Transport)"
And here we are at journey's end unloading the piling rig....

In general, Brian, the longer the semi-trailer is in relation to the length of the tractor unit, the easier the whole outfit is to reverse, particularly in a straight or reasonably straight line.
