The overall parameters of the HW220 excavator are quite impressive. In terms of appearance dimensions, its transportation overall length is 9625mm, the overall width is 2990mm, and the overall height (top of the boom) is 3075mm. Such dimension design not only ensures sufficient working space under complex working conditions but also takes into account the convenience of transportation. Whether it is on narrow construction site passages or long - distance transportation, the HW220 excavator can handle it easily.
In terms of performance, the parameters of the HW220 excavator are also outstanding. Its engine model is 6BTAA5.9 - C180, provided by Dongfeng Cummins. It is a four - stroke engine with a rated power of 133kW/2000rpm. The powerful power output enables it to work stably under various complex geological conditions. For example, in mine exploitation, facing hard rock layers, the HW220 excavator can complete the excavation task efficiently with its abundant power. Its bucket capacity is 1.0m³, and the rated bucket capacity is 1.6m³. This means that it can carry more materials each time it excavates, greatly improving work efficiency.
The working range of the HW220 excavator is also very wide. The maximum digging height can reach 10950mm, the maximum dumping height is 7190mm, the maximum digging depth is 6490mm, and the maximum vertical digging depth is 5915mm. Whether it is in the foundation pit excavation of high - rise buildings or large - scale earthwork projects, it can accurately transport materials to the designated location with its excellent working range advantages. Moreover, its maximum digging radius reaches 9860mm. When carrying out large - area site leveling and other operations, it can reduce the number of movements, saving time and fuel costs.
The traveling system of the HW220 excavator also performs excellently. The ground contact pressure is 34.9kPa, the track contact length is 4915mm, and the track width is 600mm. These parameters ensure good passability and stability even in soft ground or harsh road conditions. Whether it is on wetlands, swamps, or some rugged construction sites, the HW220 excavator can move smoothly and continue to work efficiently.
In terms of control performance, the HW220 excavator has also achieved excellence. Its main relief pressure is 34.3MPa, and the pilot pump flow is 15L/min. The displacement of the swing motor is 11.7r. These precise designs make the operation more sensitive and accurate. The driver can easily control every action of the excavator, whether it is fine earthwork trimming or large - scale excavation operations, all can be done with ease.
In addition, the structural system of the HW220 excavator is also very reliable. It uses 47 track shoes, 2 idlers (per side), and 2 carrier rollers (per side). These sturdy components ensure that the excavator can maintain stable performance during long - term and high - intensity work. At the same time, its boom length is 4265mm and the dipper stick length is 2380mm. This reasonable structural design further improves its work efficiency and stability.
With its outstanding overall parameters, powerful performance, wide working range, good traveling passability, precise control performance, and reliable structural system, the HW220 excavator has become a star product in the engineering machinery market. Whether in construction, mine exploitation, or road engineering and other fields, it can become a reliable right - hand assistant for you, bringing higher efficiency and better benefits to your engineering projects. If you are looking for a high - performance excavator, the HW220 excavator is definitely worth your in - depth consideration.
