How much wood can be dropped on concrete without breaking it?

[jefflovstrom]

We would drop and clear the street in less than 13 minutes, probably 8 minutes, we would eat anything under 18" and get out of there. Come back for the stump after you call for mark outs. Go back for a $400 dollar stump cause they really like you! :yourock:

This is pretty bad, guys. LOL, some of this crap in this thread would sink my gig so fast....

I got it. I'll do it my way. BTW, that is not a Torrey Pine.

If it is not a Torrey, then you put up a pic of a Torrey and did not know it. I saw the pic's, it is a Torrey.

I dunno, I am always chunking down on concrete and never had a problem with it breaking, maybe if it was defective concrete then it might break. Just did one the other day. I was pushing 3 foot dia rounds of oak from 30 feet high. Seemed to be ok.
I've seen tons of guys fell entire trees and bomb stuff on cement and don't recall any damage.

Cover the concrete with plywood, two layers thick. Add some brush to the top of it. Land flat. Assuming it's well poured, you "should" be ok. If it's super pristine, block the wood out. Period. Not a worthwhile risk to take.

You do all of that!!?? Dam, that's a lotta work! If you hit the cement right in the middle it can take it. The stuff ain't gonna break... unless its defective.

Ha hahaha!
You are joking, right?

What, ya gonna erect a 3 tier scaffold so you can pole saw from it?

 

[ForTheArborist]

Of course you can bomb some stuff on the concrete, but... maybe 2' - 4' rounds of this stuff wouldn't hurt it especially with the brush below it. It has a 3' dia, and it's not anything to be throwing 10' per down straight on the concrete. Really, you guys are right. With plenty of brush at the base, I can block small blocks for a few feat, and then drop bigger and bigger. BTW, it's not a Torrey. It's a Stone.

I love the responses on this thread.........go to matress world & get a good tempurpedic, place directly under tree & bomb away........hell add the sofa & lazyboy for affect!

heres the best response!........why would you ask such a dumb &*^% question? really, rig the dam thing down & be a pro!

LXT............

hands down, the best response yet . you want some rep for that? havent figure out how that works but your gona get some. my new hero here is who? LXT!!!

I had a guy onetime have me intentionally bomb the chunks out in the driveway. He was trying to bust up the concrete to get it out of there so he could pour a new one. I tore hell out of it. And yes, it is pretty easy to tear up. Even if you only drop small pieces it will still usually leave a smeared stain on the driveway. I don't like doing that. The guys I was subbing for last month (the ones who tore up the sprinkler head) was behind on their jobs because they had to rent a concrete saw to cut and patch a driveway they had tore up.

I will often drop trees and spars across driveways and sidewalks without damaging them. I just put a good log on either side to absorb the impact.

How big are these spars? Height/Diameter

I know I've seen Murphy do that on some big trees to save time rolling them not to save the concrete. They cut easier on the "cross logs."

You got it. I do it exactly like Murphy does. I will usually put a log or two in the drop path on most spars whether I am trying to protect a driveway or not. It is better to let a small log take the impact and have a small divot to fix than have an indention the entire length of the spar. And as you have already figured out it makes it easier to buck the saw logs.

As far as size and diameter, well, you have to use a little common sense. You're not going to be able to drop a 3' or better diameter spar on a one foot log and expect to protect a driveway. Most times it's best to go ahead and chunk them out instead of taking a chance of tearing up concrete or something.

One thing to watch for if dropping stems on logs, i've seen the stem hit those logs and take a weird bounce.

 

[tree md]

I dropped a 30" Maple spar, maybe a 15' spar on two logs in an ultra tight drop zone earlier this year. It rolled forward like it was on wheels and went straight for the privacy fence stopping about 2 feet shy. The HO was standing there watching me and said "you couldn't have planned that any better". I just smiled as I wiped the bullets I had been sweating from my brow...

Stems and spars aren't the same thing, are they?

I think JL has the best idea, notch into the street. you can even take the top out first if you dont fell comfortable taking it in one. The tire trick works well on cement. Take some top pieces and lay them in the street, drop the log onto that so you dont dent the street.

Butt hitch the stick you are dropping with a downgraded line. Use a porty or wrap somewhere if you feel the need to slow it down to not snap the line. Sometimes it doesn't matter if the line snaps as long as it put the brakes on the movement. I have butt hitched 60 ft 3 ft dia stems on slammers.

This thread illustrates again what a disparity there is among posters on this forum. Often the lower level guys talk like "we all" this and that as though we all on the same level of knowledge and experience.

Just looked at the pict....what a cake job....you belong in the 101 forum. I wouldn't be posting this crap if I had a year in the biz. We would swat that tree like a tired fly sitting on wall.
