wheel excavator

基本解释

The results indicate that it is feasible to employ bucket wheel excavator for coal mining based on the cutting force analysis.
结果表明，采煤选用轮斗挖掘机从切割力角度分析在技术上是可行的；
The modified formula for the boom of large complicated bucket wheel excavator has been put forward under earthquake, included the local dynamic effect.
对大型斗轮挖掘机臂架，通过考虑局部动力效应，推导了在地震荷载作用下结构单元的修正公式。
However, it is more difficult for bucket wheel excavator to work in overburden stripping than in coal mining, which means that continuous working in the whole year can not be realized.
剥离选用轮斗挖掘机从切割力角度分析难度大于采煤，无法实现全年连续作业。

In construction machinery, for example, sales of wheel loaders in April were down 28 percent, and excavator sales were down 40 percent, from the sales levels achieved in March, reflecting a slowdown in fixed asset investment.
