Electric chain hoist is a kind of lifting equipment that uses chain as a flexible transmission element. Compared with electric wire rope hoist, it has the advantages of small size and low price, so it is more widely used.
(1) Reasonable series type spectrum According to the characteristics of the electric hoist itself, the electric hoist manufacturing unit arranges a main parameter table as the series type spectrum of the electric chain block according to the main technical parameters (working level lifting weight, lifting speed, lifting height, etc.) according to the principle of priority number.
(2) The basis of serialization in the hoist design process, from the perspective of manufacturing process and economy, using the least basic type optimization combination to cover the largest range of specifications is the standard for rationalizing the series type spectrum.
(3) In the early 1980s, the European hoisting machinery design work classification theory was introduced into China. More than 30 years, the electric crane hoist manufacturing unit has applied this theory to the product series design work.
Based on the theory of crane working level division and the changes of main technical parameters, the product specifications of the electric chain pulley block stand-alone are extremely rich, covering a wider range of specifications with the least basic type.
(4) The structure is light and small, and the appearance is beautiful, The motor chain block is compact in structure, small in size, light in weight and beautiful in appearance. It is biggest advantage as a light and small lifting equipment. The electric chain hoist has a product structure design, low manufacturing cost, convenient use and high safety.
(5) As a key component of the electric chain block, the rationality of the selection is an important link related to the quality of the entire equipment. The pitch error of the hoisting chain produced in my country is effectively controlled.
(6) The chain should be driven smoothly, the manufacturing tolerance of the sprocket should be well guaranteed, and the surface hardness should be controlled within a certain range. Many manufacturers in China have solved this technical problem very well. The structural design of the chain guide is also very reasonable. The safety clutch is highly reliable.
