Bought this trolley from WCW the other day,

http://www.windowcleaningwarehouse.co.uk/shop/index.php?option=com_aceshop&route=product/product&filter_name=trolley&product_id=2494&Itemid=73

however the handle to push/pull the trolley is so low its really irritating and kills your back from bending down all the time.

Has anybody got this trolley and modified the handle in any way to improve this?

That shouldn't be too difficult to extend. Lop the top 4" off and fit some tube (outside or inside) to rejoin them together and weld. If you cant get someone to weld then add a couple of inches and drill and bolt, if you need the handle to collapse then see if there's enough for the bottom to slide down (trombone) drill another pair of holes and bolt.
Hope this helps.
