Thread: Stress on wall from Triton Wood Rack

John,

If you are going to be using your woodrack inside, I recommend that you run 2 pieces of 2 by 4 from the slab up, and secure these to the wall.

Then secure the wood rack to these.

I say this, because by having the 2 by 4 touching the slab, there will be no downward force on your wall. Just the lateral force, which given that the racks are only about 300mm deep, over about a 900mm rise, will be very small.

I import and distribute Triton in Japan and have been singularly unable to get a firm answer from any manufacturer about what will do.

Wool rack will hold 50kg
Bolts will hold 3 horses, 2 pigs and a goat.
Wall will hold......This is the question that a fear of later litigation prevents any meaningful answer.

Hence the 2 by 4. You can spread the load over a larger area and use more than 3 anchor points.

Sorry this is vague, but it is the best I have after asking many experts, including engineers. There are just too many variables.

Just out of interest, how do the wood racks work? I was intently reading the box and it looks like the racks simply slide down the vertical supports until they hit a screw head.

Now, this can't be right can it? Unfortunately I couldn't open the box to suss it out a bit more.

John as an engineer ( retired ) I will only say that what Steve ( TritonJapan ) has said makes perfect sence and proberly the best advice tou could take .

Wendy,

The racks hold themselves in position, with or without the screw head.

Each of the orange horizontal racks is a short piece of square pipe.
At the rear of this pipe, there are 2 square holes, one on the top and another on the bottom.

There is another square pipe that passes through these holes. This is a snug fit.

When there is no weight on the rack, it is easy to move it up an down. When there is a weight on a rack though, the rear edge of the top hole and the front edge of the bottom hole both grip onto the vertical pipe. The more weight there is, the tighter they grip.

For the rack to break, the steel at the rear of the rack, behind the hole would have to tear or sheer. Because the rack is not very long, there is not much leverage to do this, and so the racks can hold a lot of weight.

Wood racks are not hard to make, however they often take up more space than the timber you can store on them. These are simple to install, very strong, compact and adjustable. Seems wherever I go I leave a trail of them.

When working, they come in handy for all of the timber that is still being worked. Raw stock on the bottom shelf, rip it and put the ripped bits on the second and third shelf, etc.

Sorry, I digress.

I have bolted my Triton rack straight to the single brick wall. It is fully stacked with hard wood. No problems in 3 years.

Racks work bloody well fwiw. Mine have been up for years, and I don't know the load per shelf, but it certainly pushes the listed 50kg rating without issue, and it is secured to a very weak wall of a tin shed, without any dramas at all (held that wall down when the other half of the shed blew down a few years ago)

Hmmm. What do they cost?

I haven't noticed the rack at bunnies, is it a special order thing?

woodbe.

The wood rack has been in Bunnings for years - at least 3 or 4 (years that is)! Cost (off the top of my head) is about $65.

Thanks!! No wonder I couldn't figure it all out from just looking at the box

Cheers
Wendy

Yeah, thanks Steve, I can certainly follow your logic. However, if the weight of the rack is supported on the slab, this means that the only load on the wall is lateral. If instead the rack is suspended on the wall, most of the load will be vertical, which (for a brick wall anyway) may be preferable, since the vertical stress will anchor the brick in place (maybe???).

It's been a while since I did basic physics: say each rack (x6) is max loaded at 50kg, centred 150mm from the wall, what is total force/torque at each of the 6 anchor points? Maybe something like 10kg? Can a brick sustain that load?

Bottom line is I should probably not worry, as no-one has had any problems so far.

10kg? Put a hook into the wall, tie a rope to it, and pull. Bet 100kg couldn't dislodge a brick.
