I don't know much about the specific requirements of a certain region or industry. But generally speaking, people who repair forklifts need to have the following certificates or qualifications:

Forklift license

This is a very basic and necessary document. Only by passing the exam can you drive the forklift legally.

Maintenance skill certificate

Need to be trained and pass the exam.

safety certificate

You must abide by the safety regulations at work and pass the exam to meet the safety standards before you can get this certificate.

professional certificate

Such as repairman, mechanical repairman, electrician and other certificates, depending on the specific industry.

Relevant experience and skills

You also need to have relevant experience and skills, and have a deep understanding of forklift structure, electrical principle, mechanical principle and safety regulations.
