two post hoist

[bemm52]

brains trust88531
is there enough height for a two post hoist and what are the footing requirements
(east gippsland coastal sand)

Cheers

I have mine bolted to a 4 inch thick concrete, although the manufacturer(Molnar) recommends 5 inches.

As for height. My shed has 10 foot high walls with a portal frame roof.

I can get sedans to full height, just, with the roof going into the roof pitch.

Wagons no and my Disco's I can get to a height where I sit on a milk crate underneath.

IIRC, they lift about 1800. Measure from your 130 roof (and back of tray) to whatever will foul above it. You will need the 1800 of lift plus 125 of slab and a bit of "just in case" room.

I have 4030mm which is 70mm short of full lift height this would allow a 110 with rack and a good working height for a 6' grease monkey Floor thickness of minimum 4" and maintain at least 6" from any seam or edge to bolt holes

I'd love to get something like this .... even better would be belly lift jacks built into the ramps (which I've seen on some 4posters).

I can get my cars with no ground clearance onto 4posters (you couldn't get htem onto a 2poster as the arms wouldn't fit underneath)... and you don't need to worry about slabs 'cos they are supported from the corners.

for roof height ... why don't you stand on the roof rack of your highest 4wd and see if your head hits the roof ..... if it does so will the cars roof before your at "standing" height beneath the car.

That hoist looks to me like it has spent a fair amount of its time either in the open, or under a carport, where the rain can blow in.

A four poster wood be great to compliment my two poster, but being a retired spanner and having worked with both, if I could only have one hoist it would be a two poster.

As for lowered cars. When my son needs to put his on my two poster we have some blocks of wood which we drive the car onto.

Minus the distance from the chassis to the floor.
You don't need to lift the vehicle 6 foot to stand a 6 foot person under it as the chassis (or floor in the case of a car) is already of the ground before you start. You need to lift a sports car a foot higher than the average 4x4 before you can stand under it, and you can stand under a mining truck without lifting it at all.

I'm still trying get my head around that LOL... I get what you mean though :wasntme: with 4post ... I'm thinking my tired old cars that don't run... they can be rolled onto a 4poster ... dunno how you'd get them onto a two poster given you can't even get a jack under the mongrel things if they don't run ... Hey a challenge in life is supposed to be good for you :angel:

The first house I rented had a pit in the back yard, handy,:)
I suppose in those days cars had a 101 grease nipples.

Dunno why a 2 post hoist is such a problem, you can now get clear floor hoists with asymmetric arms, you only need 80mm to get the pads under the vehicle. (If you haven't got 80mm I fail to see how you'd get it up on a 4 poster!) Example:

I got this one , tufflift aren't sure why its called a 3.7, as its identical to the 4tonne hoist except higher.

Dunno why a 2 post hoist is such a problem,

I do. You've got to own an odd european car to appreciate this.
That is, the car is odd and european. Not all european cars are odd.

For what its worth. BMW workshop manual for Discovery 1, vol 1 Introduction p6 "The manufacturers of Land Rover...DOES NOT recommend using 'two post' ramps that employ four adjustable support arms..."

They recommend a drive on ramp where support is by the wheels, with an incorporated lift if wheels free is required.

I once lifted my Toyota LCruiser Troopy by the chassis so I could drop axle assemblies for spring bush replacement.

I used four hydraulic trolleys, placed as far forward and rear ward on the chassis as possible, much the same as you would position four arms on a two poster.

Once in that position if you leaned on the front bumper you could feel the rear start to lift off the rear supports - the engine/gearbox/front axle almost outweighed the rear two thirds of the vehicle. Take off something like the rear axle or transfer case then the vehicle is really out of balance in that scenario. I dropped the front axle first to try and maintain balance. I assume you'd have similar issues with a Rover.

Not that all Chinese stuff is junk, but the neighbour works for a crane company where directives are to use Italian, USA or other quality manufacturered lifts - with cheaper lifts too many instances of broken cast iron supports and vehicles slipping off.

The first thing I do when putting a vehicle on a two poster is lift it about 18 inches off the ground. I then grab one end of the vehicle and give it a good shake. If it does not lift any part off the hoist pad doing this, it wont fall when working on it.

I would rather have my Disco on the two poster than a large front wheel drive, where all the weight is at the front and little at the rear. I reckon a weight lifter could lift the rear of a front drive car.

Like the look of this one will do some measuring over Xmas break


Cheers and thanks all for your input........... don't know why but every time I lay on my back under a car I feel nauseous hence lift consideration.

124" wheelbase (longer than a big old chev impala) .... and 1/4inch ground clearance if you pump the tyres up really tight :)

this is one sitting on it's bumpstops (sadly not mine a random piccie from the internet).

https://www.aulro.com/afvb/images/imported/2014/12/314.jpg

this is what I have at the moment ... sucky compared to a hoist ... but if you keep and eye on ebay, you can get an old set of alignment ramps that tilt. You can winch a car with zero ground clearance onto them. But they also fit into a shed with no roof clearance

Forget the pit suggestion someone made. When I was a kid I spend a lot of time digging a pit in my fathers shed. We lined it with a plastic liner, angle the floor and put a small 'hole' in one end so any moisture would collect into that and we could scoop it out.

We found if there wasn't a broken car always parked over it .... when you need it, the damn thing still managed to be half full of water, so you'd have to pump/bucket it dry. I can remember at least 3 times I stepped backwards into it ( AARRRrhhhhhh ), one of those times I was carrying a gearbox. bloody dangerous if you have young kids around that can fall into them too :)

These cars are well known for doing a nose dive off of two post hoist..... especially if the fuel tank is empty :eek:

With a 2 post hoist drill a couple of extra holes to suit 12mm threaded inserts about 4000mm between fit socket head grub screws.When you want to drop a diff,bullbar or something that is going to upset balance install a eye bolt and ratchet strap:)

Ken make sure your concrete slab is up to it, they're only as strong as their anchor points.

Mario. Ken works in the concrete industry, so I think this shouldn't be a problem.

yes but you will be able to stand up under mine with a disco on it .....
an advantage of 6 metre roof height :p:p:p:p:p:p:wasntme:
