Once the tonnage of excavator equipment in the construction machinery industry exceedsMore than 30 tons are usually considered as large equipment by us, but there are many super large and excavator equipment in use. But due to the complexity of construction sites and equipment prices, it is difficult for individuals or small companies to afford. Purchasing an excavator for construction is one thing. If there are problems, the cost of maintenance and the purchase of repair parts may not be available for some parts factories. Even vulnerable parts need to be customized and purchased by manufacturers. Therefore, for everyone, commonly used models can reduce expenses and increase profits.
Huacheng will introduce a CAT in detail here390FL hydraulic excavator, a performance grade beast excavator equipment with a tonnage of nearly 90 tons. F-grade products are not mass-produced or sold domestically, mainly relying on imports. Although devices of the same level have already been sold in China, their influence is far less important than that of CAT brand in people's minds. The unique advantage of domestic mainframes is that their starting price will be much lower than imported ones, and our concerns about later maintenance and parts purchase will also be much lower than CAT models. However, there is still a slight gap between the core capabilities of the excavator equipment and the operational capabilities and reliability demonstrated by the equipment.
CATThe 390FL core power system adopts CAT C18 ACERT engine, with a displacement of 18.1L and a comprehensive power performance of 405KW. The performance is fierce, and there are few construction sites in China where this level of equipment cannot operate. The digging capacity of the CAT 390FL bucket reaches 364.8KN, with a bucket capacity of 3.9m according to the manufacturer's standard? It seems that countrymen can match 4.5m? The construction of the CAT 390FL model does not impose too much pressure on the work bucket. The comprehensive excavation force of the large and small arms (KN) is 235.9, the maximum traction force of the boom is 590, and the turning torque is 260, which drives the entire behemoth weighing nearly 90 tons with ease.
How can the hydraulic system, as a driving force for excavator equipment, fully utilize the performance of the equipment without a super strong hydraulic system? CATThe maximum hydraulic flow rate of 390FL is terrifyingly close to 1000 (l/min). Can you tell me how much oil the fuel tank can carry and whether frequent refueling is a problem for CAT? The total capacity of the diesel fuel tank can reach 1240L, and the hydraulic oil capacity of the hydraulic system can reach 997L. If you need to replace the hydraulic oil once, it is not a small amount of money, but there is no pressure for the equipment construction to obtain profits. If normal construction is carried out, for the comprehensive equipment rental price of the domestic construction machinery industry, the 390FL equipment is basically leased on a monthly basis. Organic owners will not calculate profits on an hourly basis.
This device is a very complicated process in terms of transportation alone. There are very few logistics transportation vehicles in China that can transport the entire machine. It is necessary to dismantle the large and small arms and adjust the weight to reduce the weight of the equipment, and even to dismantle the chassis in three vehicles. The dismantling and assembly process also involves crane equipment. Overall, short-term construction projects will not be taken by anyoneThe 390FL excavator is here to handle the work. The transportation length of the whole machine requires a length of 36 meters, a width of 4.4 meters, and a height of 5.5 meters. When you go on the highway, you must disassemble and assemble it. However, for short-term transportation vehicles, the load is too heavy and the risk factor is high. Of course, the equipment will not take risks.
What is the working range of such a large machine model with strong performance and huge size? CATThe equipment excavator of 390FL has a height exceeding 10 meters and a maximum depth of 11.8 meters, with a working radius of 17.25 meters as the basic data. Actual work may vary depending on the actual working environment on site.
CATIn this industry, 390FL is already considered a super large excavator machinery equipment. Of course, there are many larger models in China, and there are many excavators with a weight of over 200 tons. However, the price can easily exceed tens of millions, and the quantity must be rare. If you want to purchase such a new model, the staggering price is not recommended by Huacheng. By understanding second-hand equipment, you can not only save initial investment but also expand equipment leasing commissions through certain equipment reinforcement and modification. The vast majority of excavators above 60 tons in China will adopt modified large and small arms with soil loosening devices, and the rental price will increase by more than 30%. Mr. Liu from Sichuan purchased a Hitachi 650 equipment from Huacheng and modified it into a soil loosening device, renting it for over 60000 yuan per month. If there are suitable engineering projects, you can come to Huacheng site for detailed equipment consultation and customized services for ideal models.
