Crane reducers are widely used in wharfs, construction, steel plants, and other construction industries where heavy loads are required. According to the different lifting standards, they are generally divided into four categories: super large, large, medium and small.
1. Super large lifting reducer is mainly used in construction industry, dock and steel industry. Generally, its load carrying capacity is above 150T.
2. Large-scale lifting reducer is mainly used in steel industry, engineering machinery, etc., and the general load is between 50-150T.
3. Medium-sized lifting reducer is mainly used in factory buildings and small construction machinery, with load carrying capacity between 5-50T.
4, small lifting reducer is mainly used in small factory buildings, bearing load below 5T, commonly known as electric hoist.
Exterior Wall Rock Wool Insulation Board
Rock wool board, also known as rock wool thermal insulation decorative board, is an inorganic fiber board made of basalt as the main raw material through high temperature melting processing. It was successfully tested in June, 1981. Rock wool board is a new type of thermal insulation, flame-proof and sound-absorbing material.
The artificial inorganic fiber made of rock wool board by high temperature melting process has the characteristics of light weight, small thermal conductivity, heat absorption and incombustibility. The initial development is a common type of application in construction, which is mostly used in industrial buildings. It should meet the requirements of "Application Types and Basic Requirements of Building Thermal Insulation Materials". Rock wool is a kind of external insulation material. When the market share of 90% of the organic thermal insulation materials is stagnant, rock wool, as an inorganic thermal insulation material for exterior wall, has ushered in an unprecedented market opportunity.
