Abstract: The quality of gate hoist is related with the safe operation for whole hydropower engineering. In our country, quite a number of hoists in active service are aged at present stage, their performances are seriously deteriorated, and lead to the security and durability are too low. In order to ensure the production safety, give full play to hydropower engineering benefits and avoid major accidents, viewing from safe operation and scientific management, the safety monitoring and evaluation for hoists must be enhanced urgently. In this paper the contents and methods for the safety monitoring were introduced, and some pertinent suggestions were put forward. 

Key words: hoist, safety monitoring, reliability
