Single or 3 phase hoist

[07cob]

All

Given the choice, which would be preferable - a single or three phase hoist?

Cheers

It won't make a great deal of difference with an appliance like a hoist.
However if you are toying with the idea of having 3ph installed it opens your options for compressors ect.

As Gav said.

Single phase here. Works fine.

Remember single phase power outlets and cabling is cheaper than 3 phase if you want to wire a permanent power point in for it.

A great example of the importance of punctuation...lol

It's either a shot at Gav, pointing out that anything Gav says won't mean much.....

i.e. What Gav says won't make jack difference.

or,

You're re-enforcing the point that Gav made.

What Gav said, won't make jack difference.

I thought it was funny anyway .

( Easily amused, I know )

Cheers,

I know what you meant Bryan, Wazza is nothing but a **** stirring prick.
But that is probably why we find him amusing.

BTW Josie thinks nothing I say means much either...

I want to pass on a piece of advice i was told by a gentleman who has been in the hoist industry for about 40 years,building, repairing and selling them, theres nothing this bloke doesnt know about hoists of any kind, and his advice was never buy a red one, take outa that whatever you want.

This is a real surprise to me. I would've thought the 10A (legal) limit on single phase would make for very slow lift speed. It certainly limits choice of MIG welder when I looked into them. Maybe gearing helps the hoist?

Thanks Gents.

I am in the process of (re)wiring the shed which has 3 phase and will be running a dedicated line from a sub board to hang from the ceiling for the hoist. The extra cost would just be for the cable and outlet. Negligible difference overall.

Regardless, sounds like single phase is plenty so probably no need to go overboard. Just not red.

I have a 15A powerpoint at home for my welder.

My electrician had no issue with it being illegal.

I am no expert tho...

Most hoists are hydraulic so a 1ph motor does it easy.
BTW single phase power is not limited to 10amp, it is limited by your supply or cable size.

Mine is plenty fast enough even with 3 ton of Land Rover on there.

How fast does it need to be? On the ground to max height is probably only 20 sec or so. You wouldn't want it to throw the car up in the air and catch it again.

A long time ago I bought a 3 phase molnar 2 post, and converted it to a 3 hp single phase. Wasn't expensive, and with the right coupling, It doesn't go any slower.
It took a 30 amp fuse, wired to the power board. It saves on the hassles of a new meter and power bills.

without hurting myself with punctuation, most lifts use the motor to run a little hydraulic pump and the hydraulics do the work, i don't see an advantage to a 3 phase motor for just that, and most of these single phase motors require 20 amp circuits.

07COB,
IT wont matter which hoist in my Automatic transmission workshop I have both 3 of each, not one bit of difference in operation or maintance

I like my red one.


That is about 3.5 tonne of Toyota on the hoist.

Hi Guys

The 2 post hoists we have at work in our mechanical workshop run a 3 phase motor and use a hydraulic ram to haul cables under the center hump in the hoist which is between the posts.

For a personal hoist a single phase motor should be fine for vehicles that weigh up to 1500 KGS

Remember cheapest is not always the best option

Guy's,

I have a 2 and 4 post hoist ( TUFFLIFT ) both 15AMP power.

The garage was wired with 10/15/20amp outlets for different devices.

The hoists are 15amp ( but can be modified for 10amp plugs ) and the

amount of time they are used the 20 second lift time is irrelevant.

Think back to when you had to lift the car with a jack and only to knee

height.

The 2 post hoist is the best tool I have ever purchased......

Is it the best tool you have played with Stiff?
