Underground mining equipment significantly contributed to revenue growth in 2019. Need to maximize the efficiency of decline truck haulage and maintain its competitiveness with shaft haulage has led to increased demand for underground highcapacity trucks. Furthermore, miners are unable to find economically viable deposits for openpit mining.
