As I cycle around London I've noticed that Dustbin Trucks are really really noisy vehicles. While big, huge, London Buses are actually very quiet. Especially when you consider that buses are probably carrying more weight when full up with fat commuters (sorry), than a dustbin truck when full up with a whole load of crap.
So I thought I'd ask an assorted range of wise friends:
(quite a number of them thought it was a joke - 'I dunno - why are dustbins trucks so loud?')
Susanne suggested that the actually seem louder because they always come at 5 in the morning.
Caroline wondered the same thing to herself this morning. Perhaps because they truck came around at 5am?
Beaton reckons that it could be the 'crushing engine' making the noise. There is always one person who resorts to technical language, just to show that they 'know' about things...
Actually there are two people with jargon. Kate thinks that it is to do with compressors and pneumatic technology needed to compact huge volumes of waste. Impressive answer.
Kev weirdly says that maybe it is because dustbin trucks are made from old dustbin carts and tin cans.
However, the dustbin truck I saw was neither early in the morning, it wasn't full of waste and it wasn't doing any crushing that I could see. It was merely turning round in the road to head off in the other direction. And it was very very loud. Why, oh why, are dustbin trucks so loud?
