So basically you're saying the advantage is in the speed of making up, rather than deploying? (and there, it's the speed of making up to move positions, rather than to go home?)
I think that this is one of it's biggest benefits (but certainly not the only one) to make up 6 lengths of layflat, reposition down the street and get the 6 lengths working again quickly, I defy most Brigades to do that without the inevitable bunch of "XXXXs" somewhere along the line.
This is where I'm not convinced they're any better. Surely it's easier and faster to bowl out a new length of hose every 30 metres, rather than drag 150M of hose through the scrub? or am I missing the point?
this kind of depends on the area you respond to......for us, its pretty common once you're off the bitumen to find that bowling out hose is impossible.....or stupid....because of the scrub or terrain (or both). With the modern pitifully short hosereels we are supplied with (how I miss a hosereel with 100m of 25mm HP), one person can run that out and a second person (even an accountant pretending to be a firefighter)can generally start running out 2-3 lengths of layflat. As its taken off the reel rather than bowled, its relatively straight and kink free, and you can disconnect the Wajax couplings at the length required. This way 4 people can generally get 2 x 90ish metres of easy to manage hose out and get to work pretty quickly.....in my experience it takes a pretty well drilled crew to do that bowling out hose in the scrub/up a hill, etc. Having lost a person with the seating configuration of the new appliances, we can still achieve this and have an IC and a pump operater (to bowl out more hose at the truck end if needed.
We looked at a design for a drop in dead reel that we could mount on the rear step of our old appliance (when it had a step), but storage became a bit of an issue. Personally, I liked the option of sticking 3 or 4 of them in a Group Car and fitting the Groups appliances for but not with, dropping them on if needed....but apparantly they got in the way of the golf clubs
