My dad wants to know whan the first skip lorry was invented?
God knows why, can any one help?

What's a skip lorry, I know lorry is a truck... what's a skip truck!

Sorry, a lorry that carrt's a skip on the back of it, a skip is a metal container that rubbish/trash is left in, like a giant bin, but yellow.

Good one there.
Well, for our Yank friends here's what a skip is: Skip (container) - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Skip_%28container%29)

Now to the question.
Following the wiki links I came across this one: Truck - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Lorry)

There is mention of a semi trailer being made in 1881, so I would think sometime around then.

Ohhh, a dumpster

Then you want a dumpster truck, 1937 is your answer then

Waste collection vehicle - Wikipedia, the free encyclopedia (http://en.wikipedia.org/wiki/Garbage_truck)

Lowtax, sorry mate wrong truck there.
On a skip truck the rear collector (skip) is lowered from the truck bed and left to be filled with rubbish.
The truck then returns sometime later to collect the full skip.

Check out my first wiki link.

Or try this one for a closer view:

I saw that one, I should have been more specific, if you read the history it mentions this:

In 1937 George Dempster invented the Dempster-Dumpster system in which wheeled waste containers were mechanically tipped into the WCV. His containers were known as Dumpsters, which led to the word dumpster entering the language.

It was the first mention in the history section of a vehicle for picking up a waste container.

In the UK Dumpster are referred to as Dust Carts or Bin lorries.
Dumpsters are basically a large volume wheeled bin.

First skip lorries wear designed in germany by a company callled benez meirell the spelling on the name might be slightly different to what I've typed but you get the idea the reason in no this is because I have a beard and that makes me the wise one
