The 800KG elevator goes from the 4th floor to15th floor (the old one was demolished and the new one was installed. How many wallets were installed?

Removing the old elevator and replacing it with a new one means replacing the elevator.

The price of changing elevators mainly depends on the brand and quality level. Even if the same brand has the same loading capacity, the price will be different because of different grades. As for elevators used in residential areas, they don't need to be very high-grade, just medium-grade ones. We don't recommend brands here. I'll give you the general elevator market price. According to your requirements, each elevator installation costs15 ~ 200,000 yuan.
