Heavy Bag Problems

[mhor17]

Hey guys,

I recently got a 70 lb bag and some chain, and I hung it on a big metal suoport beam in my basement. The beam is completely solid, but it's one of the main supports in the house, and apparently every time I hit the bag, the floor above it is shaking pretty hard. I am concerned about cracking the walls or doing some kind of structural damage considering how much that floor is shaking. I would rather not get a stand because of price and convinience, and I am wondering if there is a way to dampen the vibration. Currently the chain is tied around the metal beam, but I have the supplies to screw it into a wooden crossbeam. I also could get a spring to hang it from, but my bag is already as close to that beam as I can get it and I don't really want it hanging any lower, so I am hesitant to do this. That being said, the spring seems like the most attracrive option and I am sure i could find a way to get the bag higher. Does anybody know if either of these approaches would be effective, or if there would be another way to significantly dampen the movement of the beam? Thanks.

Are you human or are you a gorilla ?

Well if this all true and accurate I'd suggest reinforcing the beam.

The local Y had a heavy bag, (incidentally that went away, since the heavy support chains kept breaking), that hung from a heavy duty stand - held "in place" with iron weights, but took a severe pounding anyway, even from neo-phytes like me.

Thought about getting my own in the garage, but cannot imagine hanging it from a solid ceiling, that would not sustain some damaged, even re-inforced. It would certainly be annoying in a basement, to those upstairs.

If I get one myself (no room now), I will just bite the bullet and hang from a stand and hold down with weights.

Lol my mom tried it too, and she managed to shake the floor. I'm only about 170, so I don't have heavyweight power or anything. The problem is that the whole floor is riding on that beam, and it's a really important structural componentt, so the floor above takes on basically all of the movement of that beam.

Must be a pretty small beam...

A spring would help dampen the impact.

Well from one Richard to another, that's a real good idea!

For anyone wondering, the beam is a lot like this. https://www.google.com/search?q=met...AUICCgC&biw=360&bih=559#imgrc=efNQbz7WkUSHDM:

The problem is that chain. Every time the bag bounces up a bit, 70 pounds is then stopped instantly by the chain as it comes back down, and then it bounces a few times as the energy is dispersed. The instantaneous force as that happens is tremendous. Some sort of shock absorber is needed between the mount and the bag to decelerate the bag in a more controlled manner and convert most of that energy into heat.

how long is that beam as well

long beam vibration travels

i agree with the jerking of the bag against the beam, up and down... dampen that thing

they make springs and mounts for this

 

[Wanna Ride]

I read where you were concerned about the clearance and height issue. Can you lay a piece of 2x4 or 2x6 across the top of the beam, so that you don't have the metal chain making direct contact to the metal beam? That would help isolate the impact of metal to metal. That may help some.

"Heavy bag problem"? Is that the same as "Blue Balls"?

I have had a 100lb bag hung in my garage or basement in every house over the last 20 years. Yep, without question they ring through the entire house. I tried one of the free standing frames in one house and hated it as it moved over the floor. I had to stack 45lb plates on it to keep it stationary and then it just transmitted the vibration through the floor rather than the ceiling. I have tried springs, small rubber tires and nylon straps and it still transmits some noise. I have now standardized on a nylon strap and that works OK. Still noisy but the family has gotten used to it. Turns out I am a calmer person when I have something to beat up on like a heavy bag.

No worries about damage though in my opinion. Over the years I have seen no drywall cracking or other damage from the vibration. One thing that really helps but is often not viable is a training partner backing up the bag. That quiets things up a great deal.

Pound away - Great exercise and stress relief.

Jumping up and down on the floor above the beam would probably do the same thing, right? How far are you away from the walls or support columns?

If you are mid-span on the beam, that's the weakest place for that sort of thing and the beam will move more. The closer you get to the walls and support columns, the less things should bounce. Clamping a mount, with a swivel and spring on the bottom of the beam (vs. the chain) should also help a lot.

How about anchoring the bottom of the bag to the floor as well? That way the bag can't really lift and the fall. You would need to come up with some sort of anchor point on the bottom of the bag, and then anchor an eye-bolt or something like that to the floor, then run a strap (or whatever you prefer) between the two. I suppose you could even spring load the bottom. That wouldn't affect your overall height.

In my experience, you might probably want to check your technique in punching the bag. Punches to the upper part of bag will create a jerking response from the bag. That will cause the shaking/crashing you are describing. I would YouTube a professional working out and you'll see the bag isn't jerking around. Having someone hold the bag will also make a world of difference.

I have mine mounted on a steel plate across two floor joists, the bag is suspended by 3 heavy duty springs and a small section of chain. With heavy kicks or when it swings hard it will vibrate the floor a bit but the springs take a lot out of it.

 

[Wanna Ride]

I guess a lot of guys responding, didn't read your part where you don't have much clearance room to add springs or any other devices...

 

[ynned]

You should hang it from a spring.
