I install elevators, and I have to insure the workers against accidental injury. What company will insure them, and how much will it cost? What's going on here?

If there is no aerial work (hanging directly outside the building), I will quote you a price directly:

654.38+ million death and disability limit per person;

The medical limit for accidental injuries per person is 1 1,000, including outpatient and hospitalization for accidental injuries;

Premium per person 150 yuan.

It's hard to say if there is aerial work. Some companies will make exceptions, or the price may go up a lot.

Specifically, you can call the insurance company directly, and both property insurance and life insurance companies can. Just fill out an insurance application form, provide a list of personnel and affix the official seal.
