1. Design Principle and Structure of Electric Chain Hoist
Electric chain hoist is a small light lifting equipment driven by electricity, whose design principle is based on the
combination of mechanical transmission and electrical control technology. It is mainly composed of motor,
reducer, sprocket, lifting chain, hook, brake device and electric control system. The motor provides power,
which is transmitted to the sprocket through the reducer to drive the lifting chain and hook to lift or lower
heavy objects stably. The brake device ensures safe positioning of heavy objects when power is off, and the
electric control system realizes intelligent operation of lifting and lowering, ensuring the safety and accuracy
of the operation process.
Its structural design fully considers strength, stability and space adaptability. The compact structure is suitable
for narrow environments such as workshops, warehouses and construction sites. High-strength lifting chain and
thickened hook enhance load-bearing capacity, and anti-overload and anti-derailment protection structures are
added to ensure long-term reliable use, meeting lifting needs of different scenarios.
2. Material Selection and Manufacturing Process of Electric Chain Hoist
Material selection is crucial to the performance and service life of electric chain hoists. Key components adopt
high-quality materials: the lifting chain is made of high-strength alloy steel through forging and heat treatment,
with excellent tensile strength and wear resistance; the hook is forged alloy steel with anti-corrosion surface
treatment; the motor and reducer use high-quality cast iron and alloy steel for stable power output; the shell is
made of high-strength steel plate or engineering plastic for dust and water resistance.
The manufacturing process includes multiple key steps: material cutting and forging to form core parts,
heat treatment to improve hardness and toughness of load-bearing components, precision processing of motor
and reducer by CNC machine tools, strict assembly and performance testing and anti-corrosion
surface treatment. The process balances production efficiency and quality control, ensuring stable performance
and reliable safety of each product.
3. Market Demand and Development Prospects of Electric Chain Hoist
