Electric hoist is a lightweight and compact lifting equipment that integrates lifting and transportation functions. With its compact structure and convenient operation, it is widely used in industrial production, logistics warehousing, construction and other fields. It is one of the core equipment in modern material handling systems. It achieves the lifting and horizontal movement of heavy objects through motor drive, which can greatly improve work efficiency, reduce labor costs, and meet the precise lifting needs in different scenarios.
1、 The main classification of electric hoists
1. Classify by structural form
(1) Wire rope electric hoist
(2) Loop chain electric hoist
2. Classify by driving method
(1) Electric hoist
(2) Manual electric hoist (dual-purpose manual electric)
3. Classify by special function
(1) Explosion proof electric hoist
(2) Variable frequency electric hoist
(3) Metallurgical electric hoist
2、 Application and usage precautions of electric hoist
1. Typical application scenarios
The application of electric hoists covers multiple industries: in industrial manufacturing, it is used for the handling and installation of machine tools and molds in workshops; In logistics warehousing, cooperate with the three-dimensional warehouse to achieve automatic storage and retrieval of goods; In construction, hoisting building materials such as steel bars and cement; In the field of new energy, assist in the assembly of photovoltaic modules and wind power equipment; In the medical industry, equipment and drug handling (usually small stainless steel electric hoists) used in hospital operating rooms and pharmacies have become key equipment for improving operational efficiency in various industries.
2. Key usage precautions
Load compliance: Strictly operate according to the rated lifting capacity, prohibit overloading, and confirm the weight of the heavy object before lifting to avoid wire rope breakage and motor burnout caused by excessive load.
Regular inspection: Check the wear of the steel wire rope every month (replace if the wear exceeds 10% of the diameter), the sensitivity of the limit device, and the operating temperature of the motor. Conduct comprehensive maintenance every quarter to ensure stable equipment performance.
Operating standards: Operators must undergo professional training, be familiar with equipment operation procedures, avoid shaking heavy objects during lifting, and prohibit lifting objects above personnel to prevent safety accidents.
Environmental adaptation: Select the corresponding type of electric hoist according to the working environment. For humid environments, choose waterproof type, and for flammable and explosive environments, choose explosion-proof type to avoid equipment damage due to environmental discomfort.
