Escorto. Posted August 28, 2013 Share Posted August 28, 2013 Nice. Mine is in for permit atm. Planning on having a 2 post hoist at one end. Mines 3m to the knee. But I'm having 17 degree pitch and the hoist will be in the middle/ highest part of the building. Quote Link to comment Share on other sites More sharing options...
anglia4 Posted August 28, 2013 Share Posted August 28, 2013 What is this! A shed for ants! Shits tiny on my phone. Looks pretty sweet to me though. Quote Link to comment Share on other sites More sharing options...

Rookie Posted August 28, 2013 Author Share Posted August 28, 2013 It is in Taupo. The mez isn't that big unfortunately, but the section is pretty big so heaps of room for BBQ! 2 Quote Link to comment Share on other sites More sharing options...

Rookie Posted August 28, 2013 Author Share Posted August 28, 2013 Oh and the reason the doors are different heights is because I talked to some of the old cunts at work and they all complained that they can't get their boats in their garages, just incase you were wondering.

Jase Posted August 28, 2013 Share Posted August 28, 2013 vsd can be used to switch single to three phase probably cost less than getting three phase hooked in. blow using just 100mm for a 2 post unless you have heaps of reinforcing and have had the hardness increased on your concrete. digging a footing and casting a big plate in there with the bolts sticking up would be the go. shit if it goes wrong probably only one end of the car would stove the ground?

It's all about how you spread the load though. Your house weighs many, many tonnes, yet is supported quite happily on a 100mm slab, because the weight is dispersed throughout the edge. We do robotic installs where a robot needs to be anchored down to a massively thick slab, but you can work with a thinner slab if you spread the load out. If you're using a 100mm slab you simply need to make up some arms to spread the load wider to gain back the margin lost through having a thinner slab.

BobbyBreeze Posted August 28, 2013 Share Posted August 28, 2013 I'm going for a 125mm thick slab for my hoist, my engineer calculated a 125mm slab with standard reinforcing is good for 4.5ton punching shear on a 150mmx150mm square. So a hoist on 100mm slab will be fine (seeming its 2ton per side on ~ 400mm x 400mm). 1 Quote Link to comment Share on other sites More sharing options...
Jase Posted August 29, 2013 Share Posted August 29, 2013 yeah well its not just punching shear i'd worry about as i'm guessing your car probably doesn't have a 50:50 weight split and get centred over its point of balance every time it goes up. you may well find you dramatically increase the punch shear on one set of bolts and literally be torqueing the other set out if the car goes up a bit to far forward or back of its centre of balance. if in doubt go big and as they said spread the load. chap I know was a serviceman and certifier of these things in garages also did work for insurance companies for liability claims when dodgy installs went wrong, heard countless horror stories 1 Quote Link to comment Share on other sites More sharing options...

Jase Posted August 30, 2013 Share Posted August 30, 2013 yeah but its an action or inaction thing i'm a thoughtful chap and i'd hate to see it go awry on or after your build .

sr1600 Posted August 31, 2013 Share Posted August 31, 2013 Concrete is cheap go nice and thick, go about 300mm thick under the bolts ( 2m x 2m x 200mm thick less than a cube extra ) and dont want them going rusty from being in the dirt under you slab. You only have to look at the minimum thickness for something like c6 to see how much you need when setting the bolts c6 says 90mm minimum for an m10 stud set and I guarantee your 2 post hoist isnt held down with 12 of them. c6 epcon m10 = 90mm m12 = 110mm m16 = 125mm m20 = 170mm m24 = 210mm Otherwise you wont want to be anywhere near it for half an earthquake and we have had one lately. Hate to be a dead dude for the sake of 250 bucks worth of concrete Quote Link to comment Share on other sites More sharing options...
kyteler Posted August 31, 2013 Share Posted August 31, 2013 Super keen on a hoist for my shed too (was always my plan. Will check concrete thickness. Found this which furthers the 100mm mentioning by that crazy Lotus massive shed owning man. http://www.autohoist.com.au/two-post-car-hoist-safety-bar-spreader-bar.html In use Quote Link to comment Share on other sites More sharing options...
Bling Posted August 31, 2013 Share Posted August 31, 2013 It's all about how you spread the load though. Your house weighs many, many tonnes, yet is supported quite happily on a 100mm slab, because the weight is dispersed throughout the edge. Most houses i've seen have much thicker foundations around the edge where most of the weight is supported though. Any weight within the edge is supported over large areas. With the cost of concrete ($190+/m3 last time I got some). I'd sooner put a bit more under the hoist area than have spreaders on the top as an alternative. If you already have a slab down, then obviously that's not going to be an option. All comes down to personal choice I guess. I dug out a car park area and poured a ring foundation of 100-150mm depth around it. Then had a 100mm slab and meshed the whole lot. You didn't used to even have to use mesh in floor slabs down here. Which is likely why half of the quake damaged houses just cracked in half. I'm sure the hoist would be fine on 100mm with the right reinforcing. But for the minimal extra cost, I just don't see the point. Small cost in the big picture. Quote Link to comment Share on other sites More sharing options...
