600kg + on living room floor safe?

Because I got a good deal, and I want it now rather than having to travel to a gym to leg press.
Lol at the second comment, maybe if your whipped.

It's not like a 5.1 home cinema system with a large set of floorstanders or a sub or a 75 inch TV.

Definitely not an option if you have young kids. Surely you understand it isn't normal.

Normal would be do the extension and then buy the equipment. Regardless of how good a deal it was. Deals come and go all the time.

I already have a full home gym fyi I made the official home gym building thread on this very forum. Definitely not whipped. It's just an extremely bizarre thing to do.

I use my living room to host guests. I'm not too sure how having a leg press in the middle of the room would go down.

Your operating on so many assumptions here I don't even know where to begin. Who stated that the leg press would be in the middle of the room? If you really must know the details it will be in the second living room behind the pool table in the corner of a relatively large room. This means I can still host guests and anyone else in living room 1, and living room 2 because the machine will be tucked away in the corner.

I guess you just chose to ignore the parts where I said "Because I want it now rather than having to travel to a gym to leg press". By your logic I shouldn't have a gym in the garage either and should wait for the new building to be constructed before doing anything :confused:
It's great that you made the home gym building thread. Your comments are rather bizarre. You should broaden your horizons a little.
 
It should be fine given your floorboards are of a decent quality. Especially if using decent matting as it will be spread out. Keep it to a corner of a house where arguably it should be much stronger.

Alternatively. Just store it there and do other leg exercises until you can get it on a solid floor. The power rack should sort you out for squats and you can actually use dumbbells for leg work too.

If you go down this route, and it's not used you could remove the weights to spread it out a bit.
 
You say it's going to sit behind the pool table, now I dont know much about pool table weights but that must be 2-300kg? Adding an additional 600kg to them joists wouldn't exactly fill me with confidence. More just the fact that unless you've seen your floorboards lifted its quite hard to know the quality of the timber under there. Some people can be over zealous with notching joists.
 
600kg + your weight + loading pressure. You could be exerting a greater force on the floor than you think. The floor is not designed for this, simple as that.
 
For reference, domestic floor construction is designed for an imposed load of 150kg/m2 minimum. 620/3.45 is 180kg/m2.

But if pulleys are involved, you're not lifting 500kg are you? Sorry it's a Friday which means my brain is already switched off:p.

The one I use is just a sled at ~45degrees. You sit down at an angle, put your feet on a big flat bit and push. Weights are directly hung on this.
No pulleys.

It would depend on the size of the timber joists and the thickness of the floorboards. The load can be spread a little by plywood but it would need to be thick and if you don't span additional joists it won't help a lot.

The rubber matting won't spread the load very well.

I see. I think the 45 degrees would lesson the weight though.

From the perspective of the person doing the lift, or the floor?

If its loaded up with 600kg worth of machine, weights and person then the floor is still seeing 600kg when its sat doing nothing... When moving its going to see more especially if its lands hard..

As for the person doing the ligting... Yes, angle reduces the effective weight I believe.

Ieamr for the person, although I'm thinking a lot of the weight will be concentrated in the middle. Has OP stated what his floor is made of yet?

Edit he said suspended. Brave man to put that on a suspended floor. We have concrete downstairs, and there's no way I'd put something that heavy upstairs, I reckon a standard bed and 2 people (or 3 if your having fun:p) is going to be less than half that, spread over a bigger area. Can't you just not use it until the works finished and you can move it back?
 
In order to know if your floor will be strong enough from a structural point of view, you need to know the following:
  • spacing between your joists (or the number of joists you can utilise)
  • span of the joists themselves between support points
  • cross section size of the joists
  • ideally the grade of the timber
  • where the load points are i.e. where the leg press sits on the floor. If you can position those directly over joists (would have to be very lucky) then you don't need to spread any load with ply etc., as you want all your load just to go into the joists
You then need to know how to check timber joist capacity for bending and shear.

The reality is there's not a cat in hells chance you'll know all that already, and unless you have easy access to your floor void then it's just not really worth finding out. I would try and simulate half that loading somehow and gauge any deflection/creaking, and then slowly build it up. If it's going to fail then you'll see/hear things if you are careful. Should be quite easy as you can just start off with the machine fully laden.

There are different suspended floor types, if its traditional wooden joists with floorboards I wouldnt be putting 600kg on it personally..
More modern block and beam I believe would be fine, FAR superior!
