According to the analysis of professionals, the cyclical nature of the construction machinery industry has weakened and the policy is friendly. The construction machinery industry is expected to grow steadily in 2020. Under the influence of emission standards upgrades, equipment renewal and upgrades, artificial replacement, and export growth, the cyclical nature of the construction machinery industry has weakened. According to the construction sequence, the recovery of cranes lags behind excavators by about half a year, and concrete machinery lags behind by about one year or more. At this stage, excavators, cranes and concrete machinery are performing well, and there is still a need for replacement of excavators in 2020. In the current favorable policy environment and the infrastructure growth rate is not bad, the sales of excavators may increase slightly. Superimposed on the relay of cranes and concrete machinery, the construction machinery industry is expected to grow steadily in 2020. It is expected that the boom in construction machinery will continue in 2020, and there is a high degree of certainty for the growth of late-cycle varieties.
