On September 16, at the glorious moment of the delivery of the 200000 units of XCMG excavator, two 60 ton excavators xe600 / xe690dk Max were launched at the same time. It should be noted that at the press conference, 8 cooperative enterprises signed purchase contracts for 100 new 60 ton excavators with XCMG. Does this also reflect the increasing market demand and potential of 60 ton excavators?
If you zoom in, you may find that there are many new 60t excavators in the domestic excavator market in 2021. The 60 ton excavator is mainly used for crushing and loading operations in construction fields such as open-pit coal mines and gravel mines. At present, most mine projects are equipped with dump trucks of about 30 square meters in the front four and back eight and wide body dump trucks of 60 ~ 80 tons. 60 ton products have efficient loading efficiency and excellent crushing performance, which can not only save users' labor cost, but also bring users higher efficiency and create more benefits.
At present, the 60 ton excavator products launched by domestic enterprises probably show the following three characteristics: first, the performance of the whole machine is improved, the power is strong, the fuel efficiency is further improved, and the applicability of working conditions is wide; Second, the intelligent system is further expanded to better meet the needs of mine workers; Third, the refitting space is large, which can meet the requirements of harsh working conditions such as soft rock stripping and pile driving.
In March this year, Sany sy650h excavator was heavily listed. After 2 years of painstaking research and development, the product is equipped with the latest technologies such as new electronic control hydraulic system, special crushing system and intelligent automatic construction system. It has a "smart car" cab and a stronger "four wheel belt". It has strong power, stable performance and wide application. It is reported that this 60 ton new product will become an important part of Sany's "smart mine" system to meet the needs of mine heavy load scenarios with super strength.
Immediately, Liu Gong also aimed at the 60 ton force. Clg965ehd excavator officially appeared. With its cool shape and full strength breaking hammer, it sniped the hearts of thousands of customers! Clg965ehd is equipped with world-famous brand engine, with advanced combustion control technology, fast transient response, strong output power and high fuel economy. The main pump with large displacement can be equipped with 210 type crushing hammer. According to the official introduction, clg965ehd excavator is upgraded in all aspects from power, hydraulic pressure, structure, fuel consumption, efficiency and driving comfort. It costs 65 tons of money to burn 55 tons of oil and enjoy 70 tons of income!
Behind the birth of any product must be the concentrated embodiment of customer needs. In September 2020, when visiting Shanxi mine market, d1cm reporter learned that "mining operations are mainly rock excavation, so there are not many equipment below 50 tons. First, it can't dig, second, the loading is slow, and it will be phased out in the future." the user's point of view also verifies the current market demand.
Based on this, more and more local excavator manufacturing enterprises began to work towards large-scale and further refine their product lines. At the same time, with the continuous improvement of national requirements for environmental protection and the continuous enhancement of social environmental awareness, the state and local governments have successively issued a series of environmental protection laws and regulations, such as the resolution on implementing the resolution on Comprehensively Strengthening Ecological Environmental Protection and resolutely fighting a tough battle against pollution, which has further improved various environmental protection standards, thus promoting certain changes in the field of basic construction, The construction is gradually transformed into "single shift construction, large-scale equipment and standardized management", thus accelerating the iteration of enterprise products. Meeting environmental protection requirements, ensuring work efficiency and convenient management have become the urgent needs of customers. For this reason, 60 ton products began to emerge at the right time.
Look at the market from the product, look at the product from the market. There is no doubt that 60 ton products spanning the field of earthwork application and mine construction are forming a new camp. Based on the accurate control of the domestic macro situation and market trend, domestic brands took the initiative to further refine the product line and carry out "fine operation" around 60 ton products.
Excavator market set off "60 ton heat"
Looking at the international market, foreign brands rarely launched 60 ton products before. In the face of this trend, foreign brands with long-term layout in the Chinese market also began to adapt and adjust according to the market demand.
In recent years, caterpillar and Komatsu, two international leading enterprises, aim at large excavators and continue to develop cat ? The offline of (Carter) 350, Komatsu pc500lc-10m0 and other products has brought "elite soldiers and strong generals" to mine users. Compared with excavators of the same tonnage, they have greater excavation force and rotation torque. It's no problem to open mountains and gravel, which has long become a popular choice in the market.
Earlier this year, Hyundai launched a new generation of r600bkvs excavators, which also confirmed the development trend of large-scale mining excavators. On the basis of the original 50 ton equipment, the product has customized the large and small arms. The large arm can be weighted to 5 ~ 6.5 tons and the small arm can be weighted to 3 ~ 6 tons, which can perfectly match the super large crushing hammer of 200 ~ 205 mm. The weight of the standard arm is much higher than that of the standard arm, so that it can be pressed during crushing operation, with small rebound, strong sinking potential and stronger destructiveness.
With the continuous promotion of green mine construction by the state and the further reform and integration of mining enterprises, mining equipment will gradually transition to large-scale. As the preferred cost-effective model of mining excavator, 60 ton excavator may have great prospects and win the favor of more and more mine users.
A user said: "the 60 ton excavator can dig, hammer and hook, and the loading speed is very fast. Under bad working conditions, one truck (30 m3) can be filled in about three minutes, which can not only efficiently construct, but also meet the needs of green mine construction."
How much mechanical equipment is needed for mining?
Mining is not as simple as digging a hole slowly. In the modern era, mining a mine requires many large mechanical equipment, not only the traditional equipment of pushing, digging, shoveling and loading, but also some road equipment and auxiliary equipment. Only in this way can the mining efficiency be higher and the mining cost be lower.
Of course, after the completion of mining, it is also necessary to carry out ecological restoration of the mine to turn it into green water and green mountains again.
Although the mining process is not exactly the same without minerals, here we only talk about the mining machinery and equipment that can be applied in most cases:
Grader - helps build and maintain continuous grades and appropriate drainage systems on transport roads.
Bulldozer - for pushing and transporting materials, tooling such as Ripper, scraper, coal shovel and reclamation shovel can be customized.
Road roller - compaction equipment with climbing capacity and strong compaction capacity is required for road construction and maintenance in the mining area. Liugong full hydraulic double drive roller has a theoretical climbing capacity of more than 45% and large exciting force. The compaction capacity is stronger, and it is easy to deal with the rock compaction condition of mine slope.
Sprinkler - in the dry environment of the mine, the earth rock stripping, ore crushing, mining and loading, transportation and raised dust will cause great harm to the environment and serious environmental pollution problems. Sprinkler has become particularly important in mining operations.
Compressor drilling - humanized design, Ingersoll Rand imported head, large host, large flow supply, and self-contained fuel injection pump ensure the use of start-up vent valve under extremely cold conditions and greatly improve the start-up performance of the machine.
Down the hole drill - split type, which can meet the reliable operation under bad working conditions, with high efficiency and high stability.
Integrated drilling rig - the harder the rock, the better the performance and energy saving of the product, with high degree of automation and humanized operation. Meet severe working conditions.
Excavator - in the face of earthwork stripping, road construction, overburden stripping, secondary crushing and ore loading to transport vehicles, Liugong crawler hydraulic excavator has been proved to be successful in various mining applications.
Loader wheel loader is an essential earthwork transportation equipment, which has good adaptability to the heavy working conditions such as stripping, shoveling and loading of the mine. Liugong has a variety of heavy-duty products leading the technical level of the industry, which have super power, super load capacity and stability, and the whole machine is solid and reliable.
Wide body / rigid transport vehicle - in extreme climate, heavy load climbing steep slopes, long and flat transport roads, heavy load downhill and high-altitude transport environment, Liu Gong can be competent, conduct in-depth investigation for complex mine conditions, and comprehensively optimize and match the power system, transmission system and individual system components of the whole machine.
Crushing station (crushing and screening) - Mobile flexibility + high yield, mechanical direct drive crusher design, equipped with auxiliary starting and braking devices to reduce operating costs and improve reliability.
Screening station (crushing screening) - load based feeding system and adjustable screening angle for efficient screening. The convenient two end tension screen can adapt to different applications at the fastest speed. The transportation process of hydraulic folding conveyor is more convenient and fast. High quality components and design ensure trouble free production.
Ecological Restoration - turn abandoned mines into green water and green mountains. Waste mines shall be treated, and vegetation reconstruction and ecological restoration shall be carried out in exposed, damaged and polluted mining areas.
