DPL1293 AE57FMC Mercedes-Benz Atego 1325 / Papworth Plastisol One of the last of 109 new pumping appliances for the London Fire Brigade, seen on the forecourt at Millwall fire station
The original TVAC idea was to have one body that could fulfill both roles whenever there was a demand. The Wrt Ladder equipment was in boxes that just dropped into the lockers. This helps with replacement appliances in case of breakdowns etc. The WrT has a 13.5m ladder instead of a 10.5m. When I was with Humberside there were specific pieces of equipment that a 'Ladder' carried but this is very much a brigade thing as London's needs may be very much different to say Dorset's. We were in the process of making both appliances as standard as possible but at one time only a WrL carried ground monitor, in some cases hydraulic rescue equipment, sometimes it is gas tight suits etc
In some areas of the UK a WrL will have more emphasis on rescue equipment than a WrT and a WrT will have more emphasis on firefighting. Both carry firefighting and rescue equipment. A WrL will carry a 13.5 metre ladder and sometimes a 9/10 metre ladder and a WrT will sometimes carry only a 9/10 metre ladder. So in North American terms a WrL will be the equivalent of a Rescue Pumper and a WrT a normal Pumper. Hope this helps.
Interesting, in the U.S.a engine company would only carry a 35ft(10.5M)and smaller and a ladder truck company carries the 45ft(13.5M)and smaller ladders. 13.5M ladders are a killer to use.
Les - one reason London pumpers so often carry the 45 foot "gutbuster" ground ladder is that this great city with a population of over 7.3 million souls only operates 13 front line aerial trucks! Berlin with 3.5 million has 34 and Paris with around 7 million has over 60, so neither city has to rely on super sized ground ladders.
The 45 foot ladder replaced wooden 50 foot extension ladders on five foot wheels, which were invented in the 1880s and later carried on pumper trucks ("pump escapes"). These were much easier and quicker to deploy, and even came in lengths up to 70 feet.
