The chain saw is also called a chain saw. It is a portable saw powered by a gasoline engine. It is mainly used for logging and timber production. Its working principle is to rely on the lateral movement of the L-shaped blades on the saw chain to perform the cutting action. Chain saws are generally divided into motorized chain saws and non-motorized chain saws. Chain saw is a kind of demolition equipment. According to the function and driving method, it can be divided into motorized chain saw, non-motorized chain saw, concrete chain saw and so on. Chain saws are divided into gasoline saws, electric saws, pneumatic saws, and hydraulic saws according to different sources. The advantages and disadvantages of these four power chain saws are obvious: Gasoline saw: strong maneuverability, suitable for mobile work in the field. However, it is noisy, troublesome to maintain, and generates more heat. Classification of chain saw Electric chain saw: stable power, quick start, and bulkier than other saws. But if the line is too long, it will be inconvenient to move. Pneumatic chain saw: safe and pollution-free, low noise and light weight. However, an air compressor must be attached, which increases the floor space and is restricted by conditions. Hydraulic chain saw: power is sufficient, but the start is slow and the work is stable. The hydraulic pump station is smaller than the air compressor. higher cost. China saw chains manufacturers
