Siemens supplies hoisting machines for project with world's largest single shaft hoisting capacity

Supplier News

Siemens Drives Technologies has won a major order from the Yitai Group of China to install two shaft hoisting machines with integrated 9 MW motors in a new coal mine. 

The drives for the Hong Qing He project in Inner Mongolia will be the biggest hoists in the world to feature a motor integrated in the drum. The extremely compact design of the integrated hoisting machines from Siemens will help the Yitai Group reduce their investment costs when building the new colliery. Additionally, the carbon footprint of integrated drives is smaller than that of a conventionally designed plant. 

Valued in the double-digit million range, the project, which marks the first cooperation between Siemens and the Yitai Group, will require Siemens to supply two production hoists with integrated 9 MW motors. This means the installation will include the biggest mine winder motors ever supplied by Siemens.

In order to transport personnel and equipment underground for this high capacity order, Siemens will additionally equip the mine with two service hoists, each powered by a conventional 3.8 MW motor and a 355 kW motor, as well as by SM150 and S120 Sinamics converters. 

Siemens is also responsible for the entire automation control and monitoring systems as well as for all the medium-voltage and low-voltage control panels, shaft signalling equipment, loading and unloading facilities and spare parts as well as for commissioning and training. 

The Inner Mongolia Yitai Group Company Limited is one of the biggest private corporations in China.
