QUESTION:I am looking for some friendly advice concerning a little project I
have got involved with recently. I am hoping to complete the work in a
single weekend.
The scope of the project is
1. To pull down a single car, pre-fabricated garage made from 35mm
(1.5") concrete panels. Approx dimensions of 2m wide x 5m long x 2m
high.
2. To rip up the base of the garage (10 square metres) and surrounding
concrete (10-15 square metres).
The space I have to work in is reasonably restricted. It is about
3.5-4m wide and the only access I have to the garage is from inside it
walls.
My current plan was to hire a 1.5 Ton 360 mini (with breaker) in order
be able to pull the garage down in toward the centre and to rip up the
base of the garage (2"-7" thick) and surrounding concrete drive (2-3"
thick).
The concern I have is that the breaker on the thick garage base will
not be up to the job and worse, will take too much time up. The second
is the shifting capability of the machine. 10 cubic metres of rubble
may take a while!
So in summary...... Do I hire a small 1.5T digger and have room to move
around the area, or hire a bigger 3 ton machine, restrict my working
freedom, yet be able to easily move all the material I need to as well
as cutting down on the requirement to use the breaker?
ANSWER: Well you have me confused! I've NEVER HEARD OF 5 ton machines in 30 + years
of construction relative to what you need to do a job. A certain piece of
equipment, yes, 3 ton, 1 ton etc, no, except for cranes. IE:We need a 30
ton rig(crane) blah blah. Demo work by tonnage per your description, no.
In lieu of that, it sounds as though you need/want to tear down some
concrete walls & a slab. A simple 580 Case backhoe, or similar size(416/426
Cat hoe), with a thumb on it will do what you need.
Per your measurements of about 6 foot wide x 16 feet long & 6 feet high plus
a slab about 10 feet square. A thumb wouldn't be a requirement but would be
helpful. You're looking at about 5 to 6 hours for destruction & full loadout
at the most. Mini-excavator..NO!
