In July 2025, a certain company successfully developed a "new type of coupling" and obtained a national patent authorization.
This coupling breaks the traditional integral structure in design and innovatively adopts the form of plug-in fixation of male and female components. This split design brings a significant advantage in spatial adaptability, enabling staff to easily complete the installation, maintenance or replacement of couplings even in narrow environments with limited space.
Couplings, as key components connecting various transmission mechanisms of cranes, the convenience of their installation and maintenance directly affects the overall maintenance efficiency of the machine. The launch of this new type of coupling provides an effective solution to the long-standing problem of compact internal space and inconvenient disassembly and assembly of components in the end beams and trolleys of cranes, especially bridge and gantry cranes.
