The front-end hydraulic cylinder of dump truck adopts high-strength precision cylinder cylinder, and the hardness reaches 280-320HB after quenching and tempering treatment, so that the cylinder can achieve higher hardness while maintaining higher toughness. After fine boring and rolling finishing, the inner surface roughness of cylinder is below 0.04. The surface of the cylinder body reaches 0.02 by electroplating and polishing, which can ensure better strength and performance, thus prolonging the service life of the hydraulic cylinder. The rated pressure of the dump truck cylinder is 16 mpa, and the stroke range of the cylinder is generally from 3 meters to 9 meters

Application: This series of products are suitable for water, dry field rotary tillage, plough, rake level, deep pine, transportation and other compound operation, is a water and dry field dual use of large horsepower economic tractor.
