When selecting a hand chain hoist, it is necessary to consider various factors such as the specific use scenario, load requirements, and operating environment comprehensively. 1. Determine the Load Requirements: The rated load of the hoist must be greater than the actual lifting weight (it is recommended to reserve a margin of 20%-30%). Common specifications include 0.5T, 1T, 1.5T, 2T, 3T, 5T, 10T, etc. 2. Chain Type and Length: - Chain Material: Alloy steel (such as G80 grade), which has high strength and wear resistance. - Chain Length: Select based on the lifting height (the standard length of single chains is usually 1.5-3 meters, and can be customized for extension).
