The cranes were inspected by CMI, France, and Congo-Océan Railway (CFCO), Congo, in mid-February before being shipped from Tianjin port at the end of February.

The 1067mm-gauge cranes have been specifically designed for use in Congo, with a maximum lifting capacity of 100 tonnes and a maximum lifting torque of 1000 tonne metres, while the telescopic arm has an extension of 10 metres.

CRRC says the crane is designed for derailments and other accidents and can operate under bridges and tunnels, and can also be used for loading and unloading heavy freight.

CRRC Qiqihar has developed a range of rail cranes, including 60 tonne, 80 tonne, 100 tonne and 160 tonne variations, and has annual production capacity for 30 cranes.
