From January 14 to January 20, the National Engineering Machinery Quality Supervision and Inspection Center working group conducted a type test on Yutong Heavy Industry ’s first YTQL28 tire crane and the new YT3503 and YT3621 mine dump trucks. After a week-long experiment, the expert group determined that the main technical parameters and performance indicators of Yutong Heavy Industries and Construction YTQL28 tire cranes , YT3503 mining dump trucks and YT3621 mining dump trucks met the design requirements and were approved.
During the one-week trial, the National Engineering Machinery Quality Supervision and Inspection Center working group focused on the technical parameters, basic performance, stability, structural stress, safety and environmental protection, special device functions, driving reliability, and operational reliability of the three products. Content was rigorously tested. The tire lifting project team, mining vehicle project team, technical center office, shovel transportation machinery production department, quality assurance department and other departments actively cooperated to ensure the successful completion of the test work.
The successful adoption of type tests laid a solid foundation for the mass production of Yutong Heavy Industries' YTQL28 tire cranes, YT3503 and YT3621 mining dump trucks . We believe that the success of the tire-type crane and the new mining dump truck will be put on the market, and it will become a new economic growth point for Yutong Heavy Industry!
