hxw220 hydraulic excavator is a new product independently developed by Zoomlion earth moving machinery Co., Ltd. on the basis of absorbing and mastering the advanced technology of excavators at home and abroad. According to the operation conditions, the front shovel, backhoe, loading, grab, hydraulic hammer and other working devices can be replaced. Compared with similar domestic products, this product has more advanced performance and more reliable quality. Its main performance parameters have reached the advanced level of similar foreign products in the early 1990s

1. The engine adopts the world-class four stroke water-cooled in-line injection turbocharged diesel engine produced by Cummins, which has the characteristics of high reliability, low fuel consumption, low noise and low exhaust emission. 2. the hydraulic system can make full use of power and has energy-saving control; The main hydraulic pump is a total power regulation mode with negative flow control; The system ensures the compound motion of multiple combinations; The main hydraulic components are world famous brands, such as hydraulic main pump, main control valve, rotary motor + reducer, etc. are products of Kawasaki company of Japan. 3. the monitoring system is perfect. In addition to the normal work indication, it has multiple alarm functions and fault prompt functions to ensure the safe use of the excavator. 4. the traveling mechanism has high reliability, large traction and strong climbing ability; Variable speed travel, small grounding specific pressure of the whole machine, good stability, suitable for a variety of harsh working conditions; The travel speed can be selected according to the ground to reduce the time required to move the workplace. 5. the cab is comfortable and bright, with air conditioning, streamlined design, wide vision and beautiful appearance. 6. the main structural members adopt computer-aided strength design, infrared stress test and durability test, with high reliability and long service life
