→Commercial elevator (630kg+): focus on the carrying efficiency + failure rate

→For duplex villas, inorganic traction elevators are recommended

→Add priority screw elevator to old house

✅Step3: Better after-sales service

→Whether the maintenance team is on call 24 hours a day

→The warranty period of core components is more than 5 years

→The annual maintenance cost is less than 3% of the equipment price
