Could anybody help me to find out the uk government regulations on truck mounted concrete pumps please?

I have been looking at various government websites but had no luck.

Any help would be greatly appreciated.

What exactly do you need to know?

There are no exact goverment regulations on pumps, you have to loook in specific areas for each topic you question, for example construction and use, drivers hours, regulations etc. There is a code of practice which has been formulated by members of the concrete pumping group in the cpa:
