Light work made of Heavy load
A last minute request to redirect an enormous CAT 777B dump truck from Sheerness Dock, Kent to Tilbury Dock, Essex to ensure the dump truck could be shipped to the Ivory Coast, West Africa at short notice posed considerable technical issues which our experienced Hatfield depot overcame very recently.

The dump truck which operates at 150 tonnes fully laden and stands just over 4.8 metres high needed a special width heavy haulage trailer so that its front wheels could straddle the low loader trailer enabling the height of the load to drop just below the maximum height of the Dartford Tunnel.
The outer rear wheels of the dump truck were also removed reducing the width of the load to under 5 metres. We therefore did not have to apply for a special permission (VR1) from the Highways Agency to move the load on public roads.
On the one hand the very large wheels of the dump truck had to hang over the trailer sides to lower the height as much as possible, but on the other hand the brakes had to be disengaged and able to "free wheel" in case the wheels caught the road surface when the low loader cornered.
Hallett Silbermann were given 5 working days to organise this movement which went off without a hitch – you should not underestimate the technical expertise required to safely shift this enormous dump truck.
