In terms of "saving money", the TZ4000D is considered a "smart expert" in mining equipment. The homework efficiency has increased by 23% compared to similar equipment, while the fuel consumption has decreased by 12%. With one increase and one decrease, it directly saves users a lot of costs, making it a perfect way to both hit and save money! More importantly, the application of closed core electro-hydraulic control RCS technology not only makes equipment response speed faster, excavation power stronger, energy saving effect doubled, but also avoids unnecessary energy loss, truly achieving "efficient work, saving money and worry". TZ4000D not only does a great job, but also provides thoughtful care for users in every aspect. Specially equipped with elevators that provide direct access to the cockpit platform, allowing users to save energy while eliminating climbing risks; The fully interconnected passage is equipped with protective guardrails, making it safer to walk on equipment. Not only that, datang construction machinery is also equipped with an automatic centralized lubrication system and an automatic fire extinguishing system to meet the needs of users, greatly improving daily maintenance efficiency, ensuring "no dead corners" in safety protection, and providing comprehensive protection for users, truly achieving worry free operation throughout the entire process. The brilliant debut of TZ4000D is a vivid epitome of Taizhong's deep cultivation in the field of mining equipment and its commitment to technological innovation. Nowadays, Taizhong has become the only R&D and manufacturing base in the world that can simultaneously produce mining excavators with a capacity of 4-75 cubic meters and a full range of multi power engineering excavators with a capacity of 0.8-400 tons. With its full spectrum and multi power super equipment, it is constantly expanding the "limit territory" of engineering machinery.
