A 20-volt endless chain electric hoist is a labor-saving and safe lifting device that can significantly improve work efficiency and extend the equipment's lifespan when used and maintained correctly. Electric hoists are a common type of lifting equipment widely used in industries, construction, warehousing, and other fields. According to different classification criteria, electric hoists can be divided into the following main types: 1. Classified by structural form: Wire rope electric hoists use motors to drive drums to wind steel wire ropes for lifting, with a wide load range (usually 0.5~20 tons). Features: High lifting height, strong durability, suitable for heavy loads and long distance lifting. 2. Endless chain electric hoists use metal chains as the carrying component, have a compact structure, and are suitable for light and medium loads (0.1~20 tons). Features: Small size, low self-weight, suitable for confined spaces.
