The super-large drum gear coupling and large hydraulic torque limiter developed by Wuhan Zhengtong are included in the 2024 Catalogue of Major Innovation Achievements in the Heavy Machinery Industry

Wuhan Zhengtong participated in the formulation and revision of standards as early as 2010, such as the GB/T29027-2012 large drum gear coupling, GB/T26663-2011 large hydraulic safety coupling, and GB/T26660-2011SWC large integral fork cross-shaft universal coupling. It has been engaged in the research and development and production of high-end, high-precision and innovative couplings and other transmission parts. This inclusion in the major innovative achievements is an encouragement and recognition to us. We will make persistent efforts to launch new varieties of couplings and solve industry problems.

Advocate green travel, CIMT2025 Transportation Guide

The 19th China International Machine Tool Exhibition (CIMT2025) will be grandly held in Beijing from April 21-26. This exhibition is hosted by the China Machine Tool and Tool Industry Association and co organized with China International Exhibition Center Group Co., Ltd. It is the largest professional event for machine tools and tools in the world in the past decade. CIMT2025 will simultaneously use all 17 exhibition halls of the Capital International Convention and Exhibition Center (New China International Exhibition Phase II) and the China International Exhibition Center (Shunyi Hall, New China International Exhibition Phase I), with a total exhibition area of 310000 square meters. More than 2400 exhibitors from 31 countries and regions (including China) will compete on the same stage. It can be imagined that in the face of such a large-scale and far-reaching international event, the traffic pressure around the exhibition hall is self-evident, inevitably causing traffic congestion and parking difficulties. However, Beijing has a strong public transportation network with well connected subway lines. Therefore, the organizers strongly urge exhibitors and visitors to use public transportation to improve travel efficiency and exhibition experience. After multiple negotiations, Beijing will also cooperate with the exhibition to increase subway services and support green travel.
