Car lift not working correctly

[Owen.g]

Hello everyone i am new to this fourm.

I have a big problem here.

I have a zavagli santi z21 2 post garage lift .

There are two motors (Belt on each motor on each post). (Not hydraulic )

Specs -
Art:z21
Max-20A
220v 50hz

The problem is when i lift the Lift one of the motors is lifting a slight bit higher and faster than the other.

I can make them even by getting up on a step ladder and turning the belt manually with my hands on the slower side to make it match up with the other post. ?

Any suggestion guy what the problem is ?

Cheers

I do hope when you're manually moving the belt this with the power isolated to the hoist?
The most likely reason is the drive belt needs adjusting (tightening) on the "slow" side because it's slipping. Or replace the belt with a new one if there is no adjustment available.

Is this something that it as always done or as this just developed.

As Mark said it could be a belt problem if it is something that as just developed. If it is something that as always happened then you may have a difference size of drive wheels.

I think as others have said, it’s a mechanical problem not electrical.

i also think it's a mechanical problem.
What if you swapped the belts over to see whether the problem reversed its self i.e slower on the other side due to stretch in the belt?

Thanks for all the replies, Yes this this has come into it for a wile now. Maybe it is the belt but it doesnt seem to be slipping but i will change the two around and see the result,

cheers everone for the help.

For the cost of a couple of drive belts you’d be better off changing them both.
