Midmount Platform Questions

[NewJerseyFFII]

Some fire apparatus manufactures like Seagrave Aerialscope , Kme, say that there platform apparatus with it's capability of a - 12 degree elevation are the only devices to reach ground level while " fully retracted " for ease of exit & entry. Are other builders such as Pierce , E-one , Sutphen , ALF, RK aerials available with the same capability with there buckets ?

Unless Aerialscope has done some major rework, the 95' Ascope that I am familiar with probably takes at least 40 feet to get it on the ground, no where near retracted. The KME definitely does within 25' of the truck.

If you notice, in that picture the passenger side tires are on the ground where as the drivers side are off the ground.

ALFs 100' midmount can get pretty close to that. I can't remember the exact distance. We were impressed with the 5 section aerial. We currently have 2 on order.

This was an important factor to us, so we wrote in the spec that each bidder had to supply us with the measurement from the side of the truck to the front of the bucket with the aerial at 90 degrees to the body and within 6" of the ground. Here's what we got:

ALF: 26' (93 foot MM)
KME: 24'6" (95 foot MM)
E-One: 46' (95 foot MM)

If I find the bid books I'll look for the Peirce and Scope info too, but I didn't put the info on our final spreadsheet as the costs excluded them right off.

actually, it looks like the outriggers are lifted as well...

It is very interesting to see that the E-One is almost double the measurement !...

Alf, and KME can do that because of their outrigger set up, and jack spread. Those jacks pretty much stabilize the rig like outriggers on a crane would. The reason E-one and Seagrave are 40' + is their jack spread is the shortest allowing for setup on very narrow streets.

[ladderhog]

Plus the main lift cylinders are on the sides of the ladder as opposed to underneath, and you can see that the body is not as high as the other midmounts. I know with E-One's truck the ladder can be fully extended and the bucket can be put on the ground with the shorter jack spread. Thats the big selling point short spread,lots of stability.

The E-One also is a 4 section ladder as opposed to others that are 5 allowing a shorter bedded length. I believe the Seagrave/Scope is also 4 sections? I defineately agree that the Scope and E-one are tops in the jacking systems. E-One's is awesome with just a 13 ft. spread and the single set of low underslung outriggers. As far as set up, nothing beats the E-One jack system.

[Halligan84]

Regarding the KME picture, the leveling system will bring the truck level with all wheels off the ground. Once level KME teaches to lower the rig until at least one wheel touches the ground. I have never seen the jacks on the opposite side lift off the ground with ours, I have seen it on demos of quite a few makes including KME when we were testing various manufacturers.

I was told that E-One will be showing a new mid mount tower ladder at FDIC this year.

It would be great to see E-One Fire Apparatus build a 75' Midmount Platform for departments needing a smaller rig!...

We were taught with our ladder, that all you need is the bulge out of the rear tires and the truck is then stable, once the bulge is gone the weight is transferred to the jacks.

This is also our SOP with the new ALF Tower. I understand that KME teaches the lower one tire method when you are utilizing the "One button set-up" feature which basically raises the truck up to level on its own, which often leads to plenty of daylight under each tire, so bringing one down for contact is another point of contact.
