70 ton crane not big enough

[classictruckman]

I wouldn't mind one of those, the problem is the price tag.

I agree with courierguy on this one you could have an identical crane mounted on a truck, an AT carrier, or an RT carrier and the charts would be very close, the truck may actually have a better chart if it has an over the rear chart too.

theres one of the problems. you don't see the same boom mounted on different chassis, most of the time. A regular Peterbilt boom truck 10 wheeler frame couldn't handle the loads a purpose built truck crane unit could. and a truck crane unit could handle the loads/stresses/counter weights an AT unit could. And an AT unit couldn't handle the loads of a lattice boom crawler or tower crane.....although the new 1200T Liebherr AT is very nice!

AT are the most functional mobile cranes on the market today, no matter how you slice it. longer sticks, bigger charts, better load distribution, shorter outrigger setups required, independent suspension, hydro form booms, crab steering, truck their own removable counterweights, all wheel drive, etc etc etc

until you work with a boom truck, truck crane, and an AT its tough to explain! especially in a tight area.

Ask Mark C about the setup we did @ Arborday last year. Barely got the chip truck in, and a boom truck had no chance of even beginning to make the turn, unless we removed a tree, raised power lines, and re configured a stone wall. we did it in one swing with one stop to change the height of the suspension. then picked over to where another crew would have HAD to had resetup for 1 pick. we were @ 110' and plenty of chart.

I am a little biased though!

once you see the benefits and versatilty the price is VERY reasonable!

BB, do they have balast in the tires of your AT???

no the tires stay off ground when setup on AT. plus the crane just about 90,000 the way it is, no need to make it heavier!

We had a Volvo Fe with a Tandem axle and a tag axle, we mounted a Manitex 22101S (22ton, nowhere near the cap. of your AT) on it. That truck could go anywhere that a regular car or even a jacked up 4x4 could. Weller tree service from southern Ontario owns it now

 

[classictruckman]

Wow 45 ton, I thought our crane was heavy at 28 ton with 4 axles.

 

[treedimensional]

Guess that explains the use of shorter outriggers HUH?

 

[classictruckman]

Yeah, but the huge counter weights on the tail end might help with the short outriggers.

 

[BostonBull]

We may weigh close to 45T, but with the suspension system and the floatation tires, we have less ground pressure than a chip truck!

I lost a little job last week,(2,000 lb. lap pool going in a back yard) because i would have had to set up on a 2 year old stamped/stained (decorative) driveway....of the neighbors house. They got a 70 ton to do the job from the city street. It cost them 1200 instead of me at 500. I told them my tire loading was similar to a UPS delivery van, but they didn't buy it.
