The Ingress Protection Rating (IP rating) of the GIS Electric Chain Hoist is 55. This means that the hoist has limited protection against dust ingress, and protection against low pressure water jets in any direction. The higher the IP rating of the hoist, the better equipped the hoist is to operate in a wide range of environments, either interior or exterior. Lower rated hoists are more likely to result in increased wear and tear resulting in higher maintenance costs. It can be upgraded to IP 65.
