On June 19, the rollout and delivery ceremony for Sunward's extended-range electric rotary drilling rig SWDM520EE and hydraulic hybrid rotary drilling rig SWDM240HES was successfully held at Sunward Industrial City.

Against the backdrop of the national "dual carbon" strategic goals, green development is the future direction of the construction machinery industry, and the process of electrification and intelligentization will continue to accelerate. Relevant institutions predict that by 2025, the penetration rate of electric construction machinery will reach 30% to 40%, with very broad development prospects.

As early as 2006, Sunward began committing itself to the research and development of green energy-saving technologies and products for construction machinery, and has gained widespread market recognition. In 2022, Sunward's SWDM520EE extended-range electric rotary drilling rig and SWDM240HES hydraulic hybrid rotary drilling rig projects were respectively initiated in November and December. In just half a year, the two products were successfully rolled off the line and delivered to customers, once again demonstrating Sunward's outstanding innovation strength as a leading enterprise in the comprehensive field of underground engineering.

Sunward's SWDM520EE extended-range electric rotary drilling rig is a newly developed new-energy electrified product and is currently the largest extended-range electric rotary drilling rig in the industry. The whole machine operates stably and reliably and meets the needs of all application scenarios, featuring three power modes: plug-in, extended-range, and pure electric. Among them, in pure electric mode, energy utilization efficiency is more than 50% higher than that of fuel-powered rotary drilling rigs, and construction costs can be significantly saved. The intelligent autonomous decision-making control of the machine's energy and power truly achieves greater intelligence, environmental friendliness, and efficiency.

Sunward's SWDM240HES rotary drilling rig is an industry-first hydraulic hybrid rotary drilling rig, with a high degree of intelligence and superior overall performance. The equipment adopts a high-power engine, large-displacement main pump, and large-displacement motor. The energy storage system helps increase the winch lifting speed by 15%, making it efficient and rapid. During construction, the gravitational potential energy of the rotary drilling main winch and drill pipe is recovered and reused, reducing system heat generation, lowering fuel consumption by 15-25%, and improving construction efficiency by 8-10%. Compared with models of the same tonnage, it generates more than 100,000 yuan in additional annual revenue, creating greater value for customers. Its mature and reliable integrated hydraulic energy storage system adopts a modular design and can be applied not only to the entire new series of rotary drilling rigs but also to green upgrades of existing rotary drilling rigs.

"Sunward actively devoting itself to the wave of transformation under the concept that 'lucid waters and lush mountains are invaluable assets,' turning green into gold, is one of the important reasons why we chose Sunward." At the ceremony site, Mr. Zhang from Sichuan said that, as a customer using Sunward's traditional fuel-powered equipment, he will work with Sunward to accelerate the pace of replacing fuel-powered machinery with electric machinery.

Xia Zhihong, general manager of Sunward, said that the rollout of these two rotary drilling rigs marks another important step forward in Sunward's "electrification, intelligentization, and greenization" strategy. In the next stage, as an expert in underground engineering equipment and a supplier of complete underground engineering solutions, Sunward will also invest more R&D resources, continue to leverage its advantage in "pilot-style innovation," strengthen research on key core technologies, continuously explore and study green construction machinery, help achieve sustainable environmental development, and lead the industry's development.
