求翻译：在停机水平面上，对液压挖掘机模型进行推压挖掘仿真。在停机水平面上，保持铲斗后角不变，铲斗水平推压最大距离为5.51m。是什么意思？

Stop the horizontal plane, the hydraulic excavator model to push the mining simulation. Stop the horizontal plane, the angle unchanged to keep the bucket, the bucket level push the maximum distance of 5.51m.

In the Downtime on a level surface, the hydraulic excavator models for emulation and excavation. In the Downtime on a level surface, Keep bucket rear corner, bucket level push up to a distance of 5.51 m.

In the engine off horizontal plane, carries on to the hydraulic pressure excavator model bulldozes the excavation simulation.In the engine off horizontal plane, maintains the scoop clearance angle to be invariable, the scoop level bulldozes the maximum range is 5.51m.

Down on a level surface, pushing mining model simulation on hydraulic excavator. Down on a level surface, maintain angle does not change after the bucket, bucket level push the maximum distance is 5.51m.
