Shandong Lingong E655HEV Electric Excavator: Reshaping the Future of Construction Machinery with Technological Innovation

The Revolution of construction Machinery under the Wave of Electrification

With the increasingly severe global climate change issue and the stricter control over carbon emissions by various countries, the construction machinery industry, as a traditional high-energy-consuming sector, is facing unprecedented challenges and opportunities. Electrification and intelligence have become irreversible trends, and the E655HEV electric excavator of Shandong Lingong is a pioneering work under this trend.

The E655HEV is not merely an "oil-to-electric" product; rather, it redefines the design and functionality of excavators from a fundamental logical perspective. It is not merely a device, but a comprehensive solution integrating intelligent control, efficient energy management and multiple security guarantees. Its emergence marks the leap of construction machinery from the traditional "mechanical drive" to "intelligent drive".

02 Core Technology: Independently developed controller

The core competitiveness of the E655HEV lies in the intelligent controller independently developed by Shandong Lingong it is equipped with. This controller is not only the "brain" of the equipment, but also the "central nervous system" for its efficient operation. Through real-time communication of multiple components, the controller can precisely monitor the vehicle's operating status, optimize power distribution in real time, and ensure that the equipment operates in the best condition under different working conditions.

This intelligent power management not only enhances the operational efficiency of the equipment but also significantly reduces energy consumption. For users, this means lower operating costs and a higher return on investment. For the industry, the popularization of this technology will drive the entire construction machinery sector towards a more efficient and environmentally friendly direction.

The balance between safety and efficiency of lithium iron phosphate batteries

The E655HEV adopts lithium iron phosphate batteries with high safety performance, and this choice is no accident. Lithium iron phosphate batteries, with their high energy density, long cycle life and excellent thermal stability, have become the ideal choice for electric construction machinery. More importantly, it supports DC fast charging technology. After charging for one hour, it can run for 4 to 6 hours, greatly enhancing the operational efficiency of the equipment.

However, the breakthroughs in battery technology are not merely reflected in battery life. The battery system of the E655HEV is also equipped with multiple safety protection mechanisms, including redundancy detection, insulation monitoring, high-voltage interlock, etc., to ensure the safe operation of the equipment in high-voltage environments. This pursuit of safety reflects Shandong Lingong's profound understanding of user needs.

04 Intelligent Interaction: 7-inch touch screen operation experience

On the E655HEV, Shandong Lingong has elevated intelligent interaction to a new height. The 7-inch touch screen is not only a display device but also a communication bridge between the user and the device. Through the touch screen, users can view the battery power, power and data of each module in real time, and easily grasp the status of the device.

This intelligent interaction design not only lowers the operational threshold but also enhances work efficiency. For experienced operators, it provides more accurate data support. For beginners, it greatly simplifies the learning curve. This in-depth optimization of user experience is precisely another significant breakthrough for Shandong Lingong in the field of intelligence.

05 Energy-saving Philosophy of the Heat Dissipation Management System

The intelligent heat dissipation management system of E655HEV is another highlight in the field of high efficiency and energy conservation. Through the built-in online temperature monitoring system for the environment, motor and electrical control, the equipment can intelligently adjust the fan speed according to the real-time temperature, ensuring that the equipment can maintain the best working condition under various working conditions.

This intelligent heat dissipation management not only enhances the stability of the equipment but also significantly reduces energy consumption. In the field of construction machinery, energy consumption has always been a focus of users' attention. However, the E655HEV has successfully achieved a balance between high efficiency and energy conservation through technological innovation.

06 Safety Design: High flame-retardant electrical components

In terms of electrical safety, the E655HEV adopts multiple safety designs, including redundant detection, insulation monitoring, and high-voltage interlocking, to ensure the stable operation of the equipment in high-voltage environments. Meanwhile, the application of IP67 high flame-retardant electrical components has further enhanced the safety performance of the equipment.

This ultimate pursuit of safety not only reflects Shandong Lingong's sense of responsibility towards its users, but also showcases its technological accumulation in the field of electrification. In the construction machinery industry, safety always comes first. Through technological innovation, the E655HEV provides users with all-round safety guarantees.

07 A versatile player adaptable to various working conditions

The operating weight of the E655HEV is 6,050 kg, the bucket capacity is 0.21 m³ (0.1-0.3 m³ is optional), the rated power is 34 kW, and the maximum digging force reaches 45 kN. Its maximum excavation height is 5,818mm, the maximum excavation radius is 6,125mm, and the overall dimensions are 6,165 × 1,980 × 2,557mm. This flexible design enables it to adapt to a variety of complex working conditions and meet the operational requirements of different users.

Whether it is urban construction, farmland renovation or mining, the E655HEV can complete tasks with high efficiency and stable performance. This multi-functionality is precisely Shandong Lingong's accurate grasp of market demands.

The launch of the E655HEV electric excavator not only demonstrates Shandong Lingong's technical strength but also represents a profound reflection on the future of the industry. Against the backdrop of the global construction machinery industry's accelerated transformation towards green and intelligent development, Shandong Lingong has provided users with more efficient and environmentally friendly solutions through technological innovation.
