Definition and application principle of electric hoist

Electric hoist is also commonly known as electric hoist. It is a special lifting equipment with light weight and various functions. The following is a brief introduction of electric hoist:
1. Definition and characteristics
Definition: Electric hoist is a kind of equipment installed on overhead crane and gantry crane for lifting and moving heavy objects
Features: It has the characteristics of small size, light weight, simple operation and convenient use. In addition, electric hoist also has the characteristics of compact structure, wide range of lifting weight (ranging from 0.1 tons to 100 tons), and lifting height (3 meters to 30 meters), which can meet various complex work needs.
, Working principle
The working principle of electric hoist is to use the motor to drive the hoist winch to rotate, and lift or lower the load through the winch. The specific process is as follows:
The main control valve controls the motor: The lifting equipment needs power when lifting heavy objects. The motor of the electric hoist is the main driving force. The operation of the motor drives the overall work of the electric hoist.
The lifting sprocket makes the lifting stable: the chain plays a connecting role and is a very critical component for lifting. The lifting sprocket can control the lifting chain to make it work smoothly.
Braking system: During the lifting process or at the end, the braking system will work automatically to play a braking role to ensure the safety of the operation.
3. Main types
Electric hoists can be divided into chain electric hoists, wire rope electric hoists +, explosion-proof electric hoists, micro electric hoists +, double drum electric hoists +, double hook electric hoists +, non-standard electric hoists, European electric hoists +, group hoist electric hoists +, climbing frame electric hoists +, multi-functional electric hoists + metallurgical electric hoists, etc.
4. Application fields
Electric hoists are widely used in many fields, including but not limited to,
Manufacturing: lifting and assembling heavy machinery and equipment in production lines, such as the lifting of car bodies, engines and other parts in the automobile manufacturing process.
Shipbuilding and maintenance: used to lift heavy parts such as hulls and engines, as well as to quickly disassemble and replace equipment
Construction industry: used to lift heavy objects such as steel bars and concrete components to improve construction efficiency and ensure worker safety
Warehousing and logistics: help move and stack goods, especially heavy equipment and materials, to improve the utilization rate of storage space and the efficiency of cargo handling,
Mining development: used to move ore, equipment and other heavy objects,
Rural areas: used to lift heavy agricultural equipment, feed and crops, etc.:
Port loading and unloading operations: usually used for lifting and moving containers, reducing operation time and improving logistics efficiency. Power industry: lifting heavy equipment such as transformers and generators during the installation and maintenance of power equipment. Mechanical and electrical maintenance: quickly lift equipment that needs to be repaired to facilitate technicians to inspect and replace parts.
Furniture decoration and moving: help move heavy furniture and building materials, as well as quickly lift and move heavy objects.
