Quality improvement never ends, how to build the Lovol FR510E-HD excavator

The Lovol FR510-HD excavator was once splendid at the Bauma CHINA 2018 in 2018. This new model with a powerful sense of power has attracted everyone's attention. There are many customers at the BMW Show. Detailed consultation was carried out, and the order was finalized and went directly to the customer site after the exhibition. Recently, Guo Gang, director of the Leiwo Zhongda Digging Platform, unveiled the history behind the birth of this model.

Policy driven product demand

At the beginning of 2015, the state issued relevant regulations, which imposed strict restrictions on the application of explosives in metal non-metallic mines. The demand for large-scale excavator crushing operations climbed up, followed by product application problems.

In 2016, when Leiwo engineering machinery R&D experts conducted market research, many customers reported that the original large excavator type had many problems when assembling the breaker. The pipeline and system debugging of these excavators were mainly for the bucket. And other attachments, but the hammer is more challenging for the hydraulic system, the customer can not fully play the performance of the product, and even affect the quality of the product. In the face of urgent market demand, the research team of the Leiwo Engineering Machinery Group has established research and development.

Advanced hydraulic technology for efficient production of products

In April 2018, the Lovol FR480E excavator won the market contribution gold award in the annual TOP50 product evaluation of China Construction Machinery. Its outstanding product reliability and energy saving performance have been highly recognized by mine users. This is the result of the technical breakthrough of the Revo research team and the basis for the launch of the Revo FR510E-HD excavator.

The Lovol HD series models are mine-renovated models, covering a total of 5 models of 26-51 tons, of which FR510E-HD is specially developed for crushing conditions. In the case of crushing conditions, the hardness of different rocks and soils is different, and the hammers used are different. One is a rock of level 4 or higher. Customers prefer to use a larger breaker, such as a breaker with a welding surface of 195 or higher. To meet this demand, the Lovol Engineering Machinery Group first adjusts the existing hydraulic system to ensure the flow of the system. Pressure and chassis of the whole machine enhance product reliability; the second is to have some soft rock and soil, need to install high-frequency hammer, and the flow demand is greater.

Guo Gang said, “The excavators on the market are all a main pump for the crushing conditions. One hydraulic pump supplies the crusher. The flow of the single hydraulic pump cannot meet the requirements of the high-frequency hammer. We adjust the technology. After that, the user can select the double pump for oil supply when selecting the high frequency hammer. This is the dual pump confluence technology.” The breakthrough in hydraulic technology is an important part of the Lewo FR510E-HD excavator going to the market.

Electronic control and intelligence make construction easier

The reason why the excavator is called the jewel in the crown of engineering machinery is not only because of the high unit price of its products, but also because of its high technical content. In recent years, in order to meet the user's demand for various working conditions, an excavator can be equipped with a variety of attachments to meet a variety of working conditions. For example, there are many types of breakers required for crushing conditions, which poses a higher challenge to the control system of the excavator.

The electronic control system of the Levo construction machinery excavator product has a long-standing reputation in the industry, Guo Gang said. “We have developed a control system. When the excavator is equipped with different hammers or other attachments, there is no need to adjust the main valve. The main pump and hydraulic line provide a variety of modes for the customer to choose directly on the display. The breaker 1, the breaker 2 and the breaker 3 are also installed. In addition, the customer customizes this mode to meet customer needs. The breaker 1 is equipped with a hammer of 185 or less, the breaker 2 is equipped with a hammer of 195 or less, and the breaker 3 is equipped with a high-frequency hammer. For example, when a ripper is used, the power system and the hydraulic system are exclusively matched, which greatly enhances the operation of the product. Sense and reliability, the ability to play the product more efficiently."

In recent years, Leiwo Engineering Machinery Group has made great progress in the process of product intelligence. The Lovol FR510E-HD excavator product can be described as a big man with great wisdom, 8-inch LCD screen in the cab, and Leiwo engineering machinery intelligent construction solution (iBuilding), which is more convenient for the mine customer's fleet management and construction monitoring.

Strengthen structural parts and high-end components to ensure high reliability

One of the words that martial arts people often say is: "Exercising the muscles and skins, practicing a breath inside." The same is true for excavators. Both internal and external repairs can improve product quality. Under the broken working conditions, the working environment of the excavator is very bad, and the flying sand, cold wind and ice are often accompanied. The Lovol FR510E-HD excavator has been greatly strengthened in the four-wheeled belt. Guo Gang said that in the crushing condition, the construction environment is bad. To ensure product reliability, first of all, the brake assembly of the original 48-ton excavator is required. The track chain section, the axle and the hub of the wheel train are reinforced; the second is to enhance the sealing performance, using the track rail track with life-long self-lubricating and sealing; at the same time, improving the high temperature resistance, low temperature resistance, the roller and the guide wheel Extremely cold-type lubricants and seals are used to ensure proper operation at an ambient temperature of -40 °C. ”

The Lovol FR510E-HD excavator continues the tradition of the high standard of the core components selection of the Levo Construction Machinery Group. The Cummins engine has a power of 298 kW and the power is super strong; the hydraulic system is a collaboration between Revo and Kawasaki. Relying on the research and development system of the Revo Japan Engineering Center, the perfectly matched core components have greatly improved the service life of the products.

Continuous improvement is a key factor in the sales of Revo's engineering machinery products. Nowadays, the recently launched Revo FR510E-HD excavator has already exerted its strength in mines in Guangxi and Hunan. In Chongqing and other places, the Lovol FR510E-HD excavator equipped with ripper is also easy to handle the hard soil of the alluvial plain. Tracing back to the source, all the progress comes from the process of Leiwo Engineering Machinery Group discovering and satisfying customers' needs. It is such a "customer-centered" concept that has created a series of excellent machines such as the Lovol FR510E-HD excavator. type. (This article is from Revo)
