warranties vary from one mfg to the other
check with the machine manufacturer as to what the warranties are for whatever machine you have a question about.
Most standard warranties are 1yr - 2000hrs but with new technology now a days some mfg's have boosted thier standard warranties to 2yrs - 4000hrs and their standard maintenance intervals correspond with the increase as well.

and yes there are extended warranties but those vary as well depending on what you want to pay for.

there is no definitive answer we can give you without knowing the manufacturer and model lift your speak of.
