Many individuals in the process of purchasing equipment often find themselves unclear about what an electric hoist is, sometimes even confusing it with a winch. So, what exactly is an electric hoist and what are its functions? Let’s dive into the fascinating world of electric hoists!
Electric Hoists: Varieties and Applications
Electric hoists come in various types, including wire rope electric hoists, chain electric hoists, and explosion-proof electric hoists. They are lightweight lifting equipment widely used across various industries. Typically, they are installed on single girder cranes, bridge cranes, gantry cranes, and suspension cranes. With minor modifications, they can also be used as winches.
Components and Design
An electric hoist consists of mechanical and electrical parts. The mechanical section includes components like the reducer, lifting motor, traveling motor, traveling wheel, hook device, drum device, couplings, etc. The electrical part comprises the power switch (iron box switch), power supply cable, safety conductive line, collector, lifting limiter, control box, and more. Electric hoists feature an integrated electromechanical design. They are powered through a conductive line and operated by a handle. The control circuit within the control box governs the lifting and traveling motors, facilitating the lifting of equipment and materials.
Essential for Improved Labor Efficiency
Electric hoists are indispensable in enhancing labor efficiency and improving working conditions. They are characterized by their compact size, light weight, simplicity of operation, and convenience. These hoists are used in industrial and mining enterprises, warehouses, docks, and similar locations. Most electric hoists are operated by a person using a button on the ground, from a control room, or via wired (or wireless) remote control.
The Role of Electric Hoists
The primary function of electric hoists is lifting, raising, pulling, loading, and unloading heavy objects. They are used for tasks like inverting and welding oil tanks. These hoists are ideal for installing and moving various large and medium-sized concrete structures, steel structures, and machinery. They are applicable in a wide range of sectors including construction installation companies, civil engineering projects in factories and mines, bridge construction, power, shipbuilding, automotive manufacturing, construction, highways, bridges, metallurgy, mining, slope tunnel, and well shaft management and protection. Electric hoists play a pivotal role in the mechanical equipment used in these basic infrastructure projects.
