Deep Analysis of Cat® M320D2 Wheel Excavator

Wheeled excavators are fully utilized in airport, ports, oil fields, mineral deposits, urban and rural construction, farmland and water conservancy, and quick repairs, and other distinctive features, such as fast walking speed, flexible and rapid transit, and quick replacement of various operating devices. Known as the "Swiss Army Knife" in the field of construction. This name of the wheel excavator is not indefinite, but relying on the "three heads and six arms" of magical powers and "eighteen martial arts" spell out. The three-headed six-arm refers to a wheeled excavator that can be equipped with many machines and is used by multiple machines. The 18-armed martial art refers to a wide range of applications for wheeled excavators, including demolition, site leveling, foundation excavation, loading and unloading of materials, loading and transportation, digging trenches, and backfilling. Application conditions such as land reclamation, land reclamation and hoisting are all-round hands in municipal engineering.
According to statistics, in western developed countries, the demand for wheel excavation accounts for about 12% of the total demand for excavators. In some regions, it even reaches 70-80%, which is widely used. From a worldwide perspective, the application prospects of wheel digging in China remain to be tapped. It can be said that at present, it is a good time for wheeled excavators to develop in the Chinese market. From the national perspective, the government is vigorously promoting new urbanization, shantytowns, and affordable housing construction, providing a good market basis for wheeled excavators. From an industry perspective, the development of the Chinese construction machinery industry tends to be rational, and the users of domestic construction machinery are also becoming more and more rational, which also provides an opportunity for the development of wheel excavation which is an efficient and cost-effective equipment.
Recently, Caterpillar introduced the Cat M320D2 wheeled excavator, which is tailor-made for the Chinese market and emerging markets. It has great advantages in terms of reliability, work efficiency and intelligence.

Cat M320D2 Wheel Excavator

The Cat M320D2 is equipped with a Cat C7.1 engine, which provides a maximum net power of 128.8 kW at a rated speed of 2000 rpm, with superior power, ultra-high fuel efficiency and superb reliability. A variety of engine power modes are preset to help users achieve a better balance between productivity and fuel efficiency. The configured hydraulic legs can be individually controlled, allowing the device to remain even if it stops on a gentle slope. Cat M320D2 can reach a maximum speed of 37km/h and can be quickly transferred at the construction site, allowing users to spend more time on construction. Caterpillar creatively configured a dedicated rotary pump for the Cat M320D2 to increase the slewing performance to a greater extent without reducing the power of other hydraulic functions, making the combined action smoother and faster.

Professional tooling <br> The real master must be both external and internal. In addition to rich and flexible configuration and eye-catching performance parameters, how to help users make greater use of the equipment in their hands is also Caterpillar's focus. Cat M320D2 can be equipped with a variety of work tools, can adapt to a variety of working conditions, in addition, Caterpillar R & D team developed tooling quick connector, can achieve rapid conversion between different tooling, and greatly expand the function of the device.

Taking the more general demolition of buildings as an example, the common practice at present is to directly use a bucket or a breaker to break the load-bearing wall or concrete frame and cause the building to collapse. Although this approach is simple and direct, it will produce a lot of dust, pollute the surrounding environment, and it is highly dangerous. Cat specializes in hydraulic shears, hydraulic crushers, multi-function processors, dismantling grabs, and engineering grabs for this condition of wheeled excavators. In the process of demolishing a building, large pieces of material can be removed from the building and then subdivided. The professional hydraulic shear brings three advantages. First, it reduces the dust pollution to the environment, the second is to reduce the risk, and the third is to facilitate the recovery and reuse of materials.

One Machine Almighty <br> With the pursuit of high construction efficiency, municipal engineering often requires an excavator to solve all construction problems. Cat Tooling has a wide range of tools to choose from for different conditions and is sufficient for any conventional construction. Just for material handling, Cat has a wide range of tools such as buckets, engineering grabs, and thumb clips. For road construction, Cat has also developed a vibratory plate to meet the need for smooth pavement. Taking the renovation of the road as an example, under the help of Cat tooling, Cat M320D2 can independently complete the entire process of crushing old roads, excavating roadbeds, crushing materials, filling new materials, and leveling the ground. From the beginning of construction to the end of construction, various types of tools, including hammers, buckets, engineering grabs, vibratory plates, etc., can be quickly equipped and efficiently constructed by the Cat M320D2.

The development of tooling is not just as simple as developing tools. Caterpillar has a professional tooling team to design tooling for its own equipment. Therefore, all toolings are not only connected to the equipment, but also matched to hydraulic systems and even software. Perfect. Based on the knowledge of the Cat wheeled excavator, the R&D personnel will fully consider the stress distribution of the excavating arm when designing the tooling, and at the same time, the hydraulic piping also adopts the bolted connection instead of the welding method to reduce the damage to the strength of the structural member. This is an inherent advantage and is unmatched by any other tooling manufacturer. Cat presets the flow and pressure required for different tooling on wheeled excavators, allowing the tooling and mainframe to be optimally matched so that the equipment can achieve greater performance while reducing energy consumption. After replacing the tooling, the user can start the construction immediately by selecting the corresponding construction plan with a single key.
Generally wheeled excavator switching tooling efficiency is very low, in order to pursue efficient construction, Cat designed a quick connector for the wheel excavator. The switching between different toolings takes less than 30 seconds, greatly improving the user's construction efficiency, while also significantly reducing labor costs and labor intensity.
In addition, thanks to Cat's powerful and powerful data collection capabilities, Cat Intelligence System can collect working hours and fuel consumption. Users can know their equipment usage when they are sitting at home, so that construction work can be arranged more smoothly.
As wheeled excavators gradually move toward ordinary people in China, the Cat M320D2 is bound to become another classic Cat equipment. (This article comes from Caterpillar click to enter Caterpillar online purchase page )
