Recently, Shandong Luqi Heavy Industry Machinery Co., Ltd. (hereinafter referred to as "Luqi Heavy Industry") has successfully completed the comprehensive acceptance and delivery of a **300-ton supercapacitor electric flat car** customized for a client. The successful commissioning of this equipment not only serves as another testament to Luqi Heavy Industry’s technical prowess in the field of heavy-duty special transportation equipment, but also injects strong impetus into the high-efficiency and green transformation of the client’s industrial production processes.
The delivered 300-ton supercapacitor electric flat car is a **turnkey project** tailored by Luqi Heavy Industry to meet the client’s actual working conditions. Adopting supercapacitor power supply technology, the equipment boasts an effective capacity of **≥75 Kwh**, a cycle charge life of up to **50,000 times**, and a charging time of **≤20 minutes**, making it ideal for high-load, high-frequency operation scenarios such as steelmaking. It also meets the **IP65 dustproof and waterproof standard** and can operate stably in a wide temperature range from **-35℃ to 65℃**, fully satisfying the client’s stringent requirements for production environments. In terms of core configurations, the electric flat car adopts four-wheel drive frequency conversion control, equipped with **4 variable frequency motors each with a power of ≥15 KW**. Its running speed is adjustable within the range of **2–20 m/min**, and the positioning accuracy reaches **±15 mm**, ensuring precise and safe transportation of heavy loads. The wheels are made of **42CrMo forged material**, with the tread and inner side of the wheel rim undergoing surface quenching treatment, achieving a hardness of **HB 300–380** and a hardened layer depth of **15–20 mm**, which significantly enhances the equipment’s wear resistance and service life. In addition, the equipment is equipped with dual operation modes (wireless remote control and control cabinet), an audible and visual alarm system (issuing a warning when the power is below 30% and automatically shutting down when below 15%), and an emergency aviation plug, providing all-round guarantees for operational safety and the equipment’s continuous operation capability. Since the project kicked off, Luqi Heavy Industry has strictly adhered to the philosophy of **"Integrity, Communication, Cooperation, Win-Win"**. It has efficiently advanced the entire process, from preliminary on-site surveys and drawing design, to mid-term manufacturing and assembly as well as in-plant pre-acceptance, and further to post-stage on-site installation, commissioning and personnel training. The total project cycle took **150 calendar days**, including **100 days of manufacturing, 30 days of installation and commissioning, and 20 days of trial operation and acceptance**, with all stages successfully completed as scheduled. Prior to delivery, both parties conducted a series of tests in accordance with the **Acceptance Outline**, including no-load operation, load testing and safety performance verification, with all indicators meeting or exceeding the standards specified in the contract. To ensure that the client’s operators proficiently master the equipment operation and maintenance skills, Luqi Heavy Industry has specially organized theoretical and practical training sessions. The training content covers the equipment’s working principle, electrical control logic, daily maintenance procedures and troubleshooting methods. It has also provided a full set of technical documents, including mechanical drawings, electrical schematic diagrams, annotated PLC programs, and operation and maintenance manuals, offering technical support for the long-term stable operation of the equipment. As a professional manufacturer in the domestic heavy-duty lifting and transportation equipment sector, Luqi Heavy Industry holds a number of qualification certifications, such as the Special Equipment Manufacturing License (covering installation, repair and modification), ISO9001 Quality Management System and ISO14001 Environmental Management System. It has previously provided similar high-quality equipment for many enterprises including ERzhong (Deyang) Heavy Equipment Co., Ltd., Shandong Luli Iron and Steel Co., Ltd. and Shiheng Special Steel Co., Ltd. The smooth delivery of this 300-ton supercapacitor electric flat car once again demonstrates the company’s technical advantages and service capabilities in the R&D and manufacturing of special electric flat cars. Moving forward, in accordance with its after-sales service commitment, Luqi Heavy Industry will provide a **12-month warranty period**. If quality issues arise during the warranty period, technical personnel will respond within **8 hours** and arrive at the site to resolve the problem within **48 hours**. Additionally, it will arrange on-site accompanying production guidance for no less than **30 days**, continuing to escort the client’s production and operation activities. --- 我可以帮你整理这份译文里的**专业术语对照表**，方便你后续查阅使用，需要吗？
