2 post ramp advice

[popleyruss]

Right then i need a 2 post ramp but have no access to 3 phase so its gotta be 240v
Also whats the main height of the roof ?? Litrally advice would be quality cheers

240v ramps are ok. Not as fast as three phase but they do.

Think the floor needs to be something like 20cm deep concrete reinforced.(dont know whether garages come with floors like that?)


Not sure what you mean by main height of roof. But you'll need about 3.5-4m space above car.

You need to dig out the floor about 6" or more in an H-shape where you want the ramp and lay steel-reinforced concrete, or there's a good chance your ramp could fall over!

Make sure you lay the floor level, too!

Thats the size u kinda get the size comparison of it its an old cattle shed that have all been converted im guessing its decent concrete under whats been poured on the smooth bit thats there now need an expert i rhink lol

had the same problems a while ago.

singel phase ramps can be just as fast as 3 phase, at the end of the day the speed at whitch the ramp lifts is a product of gearing / mecanical or hydralic advantage and power avalible to the system.  you won't find meany car ramps with more than a 3HP 2.2 kw motor be they 3ph or 1 ph but a 2 ton lift will be faster than a 4 ton  not that that really matters much anyway.

as for what your bolting it down to

a cattel shed will more than likely have a 150mm  ( 6" ) slab ,  you'll need to drill it to confirm this   it may be mesh reinforced but there again it might not be, a metal detector will answer this.

i would have no issues working under a ramp on a 150mm mesh reinforced slab.

if your floor is below this spec like mine (   floor in mine is 125mm  not reinforced and sh!t concrete and there is a join in it )

1)  DIG out a cubic meter hole below eaxh post and fill with ready mix  ,  sounds good solution but it sucks the two blocks arnt joind so may well allow movement.

2) dig out a cubic meter below each post then a trench ( width of holes ) 1 meter wide and 300mm deep joining the two holes together, reinforce with mesh and fill with ready mix,  problem with this is landlords don't like you cutting holes in there floor

3)  buy ramp with steel H frame bolt it down and bolt the ramp to it.   jobs a goodun

my ramp is only a cheepy but not had any problems with it so far touch wood

launch 4 ton H frame,   1900 mm lift, singel phase 2.2 KW

 please excuse the sh!thole state of the workshop





decided a new cheep lift was the better option as most 2 posters for sale round here were 3 phase and needed money spending on them and were overpriced to start with,  i hate ramps that use lift nuts or rely on cabels  for lifting,  much prefer them to use cabels for balanceing and lift with hydralics

Cheers for all that info danny the whole farms pretty much concrete they have just poird a smooth floor so fingers crossed i need to find someone local i fuess to come have  alook at the floor for me and drill it then go from there i guess
How much did u pay for ur single phaze ??
Ive them for as little as 1100

I would NOT trust farm concrete to put a lift on!

Other units have ramps instald but none on my section

doesn't look like there's much height there to me.
