On June 17, 2026, information from the State Intellectual Property Office showed that a patent titled « Shock-absorbing sealing structure, cab and loader » applied by Guangxi Liugong Yuanxiang Technology Co., Ltd. and Guangxi Liugong Machinery Co., Ltd.
was authorized.
The authorization announcement number is CN224363380U, and the authorization announcement date is June 16, 2026. The patent application number is CN202521428814.5, the application publication date is June 16, 2026, and the application date is July 9, 2025.
The patent summary shows that this shock-absorbing sealing structure belongs to the field of loader technology.
Il comprend un premier composant amortisseur, un second composant amortisseur et un composant de réduction du bruit.
The first shock-absorbing component is connected between the sole plate and the vehicle frame, the second shock-absorbing component is connected between the mounting plate and the vehicle frame, and the noise reduction component is sealingly arranged between the sole plate and the vehicle frame.
Le composant de réduction du bruit comprend un premier composant de réduction du bruit et un second composant de réduction du bruit. Le premier composant de réduction du bruit est disposé au niveau de la bride de la plaque de pied.
The second noise reduction component is attached to the vehicle frame, and the first noise reduction component and the second noise reduction component are in contact with each other.
This kind of shock-absorbing sealing structure can significantly improve the shock-absorbing effect of the cab by arranging the first shock-absorbing component and the second shock-absorbing component, thereby effectively reducing the noise in the cab.
At the same time, the first noise reduction part and the second noise reduction part provided between the frame and the foot plate form two noise reductions, which further reduces the noise in the cab, improves the driving experience, and has low improvement cost.
Tianyancha data shows that Guangxi Liugong Yuanxiang Technology Co., Ltd.
was established on February 27, 2023. The industry it belongs to is the technology promotion and application service industry, and the scale of the enterprise is large. L’entreprise a investi dans 1 entreprise étrangère, a participé à 6 projets d’appel d’offres et dispose de 303 informations sur les brevets.
LiuGong was established on November 8, 1993 and listed on the Shenzhen Stock Exchange on November 18, 1993. It is a well-known enterprise dans l’industrie nationale des machines de construction. Son activité principale concerne les machines de construction et les pièces et composants clés, avec une profonde accumulation technologique et une chaîne industrielle complète.
In 2025, Liugong’s operating income was 33.144 billion yuan, ranking 4th among the 23 companies in the industry, higher than the industry average of 16.765 billion yuan and the median of 6.689 billion yuan, but there is still a gap with the first XCMG Machinery and the second Sany Heavy Industry.
Parmi ses principales activités, les revenus des engins de terrassement s’élevaient à 20,45 milliards de yuans, soit 61,70 % ; les revenus des autres machines et pièces de construction s’élevaient à 9,611 milliards de yuans, soit 29,00 % ; les revenus des machines précontraintes s’élevaient à 2,523 milliards de yuans, soit 7,61 % ; les revenus des activités de crédit-bail se sont élevés à 560 millions de yuans, soit 1,69 %.
In terms of net profit, it will be 1.409 billion yuan in 2025, ranking 8th in the industry, slightly higher than the industry average of 1.362 billion yuan, and much higher than the median of 530 million yuan. Cependant, il reste encore beaucoup à faire par rapport au premier Sany Heavy Industry et au deuxième XCMG Machinery.
