Several problems exist in the commonly used hydraulic balancing circuits, such as drift in re-lifting of suspended load and shock and Vibration in lowering.

工程机械常用的液压平衡回路，存在着悬垂负荷再提升下滑和下降冲击、振动的问题。

In addition, for the X-drift asynchronous problem caused by Y-drift tool position variation, load dynamic compensation is proceeded.

此外，还针对Y轴方向上的由于刀架位置变化导致的X轴方向上的不同步进行了负载动态补偿。

The steel and the heat treatment process of fine heavy load drift was determined by means of production tests. And the satisfactory result was obtained.

经应用试验，确定了精密重载冲孔模的用材及热处理工艺，获得满意的效果。
