Car scissor lift

[GSR]

Looking at in ground scissor lifts, but most scone hand lifts seem to be 3 phase. Has anybody had any experience changing these to single phase?

Thanks

Just use a phase convertor

Are there any types of converter to avoid, or a type specifically suited to a lift?

If you go for a Hydraulic lift you can always stick a single phase motor on it to drive the pump.

Thanks, it’s this type of lift that I’m looking at

It needs 3kw 3 phase. So guessing a rotary converter like this:

RT-4KW Rotary Single to Three Phase Converter 4kW/5.5hp

Rotary Single to Three Phase Converter, 4kW or 5.5hp. Converts single phase supply to 3 phase and is suitable for running three phase motors from a 230Vac supply.

would be the sort thing I need?

Generally single phase ramps use a lower power motor with a lower displacement pump than their three phase equivalent to allow for the fact single phase motors don't like starting under load.
You do get single phase motors that will start better under load, but the startup currents involved are quite high.

If you want to use a phase converter with a ramp, you'll probably need one at least 3x the rated motor power to handle the start up current requirements, possibly more.

I wasnt sure if the converter had to be bigger than the rating of the motor.

My son has wanted one of these for years And has decided to bite the bullet as he has been looking at second hand ramps and they seem to go for silly money. Almost as much as a new one with warranty and single phase without messing.

I been buying single phase lifts from these people. Not had a problem with anything I bought yet!

Last one - was this one

AS-7430H 3.0T Low Entry Full Rise Scissor Lift - Automotech Services Limited

The AS-7430H Full height scissor lift uses a single scissor action to gain full working height. This makes the lift very stable during raising and lowering operations. The AS-7430H also has the added advantage over other surface mounted scissor lifts in that it is mounted within its own frame...

I still like our two poster better for some jobs!

I looked at those too, but the low height was against it for my needs.

I would not buy a mid rise lift - all ramps we got are full height.

But you do have the headroom.

I don't have the headroom inside, but I now have a four poster outside.

How is the outside ramp working for you?

I thought about this myself in the past.

Seems fine. It is a free standing type, just as well because nobody is interested in doing the ground works for me.

I only ever had surface mount ramps - can't think a dug in one - would be any good outside - fill with water.

better get some decent knee pads and a creeper....

Too much junk around you tried 2 hated them sold on in less than 12 months would be a last resort
