Yantai, China — As construction projects demand higher accuracy and lower operator workload, Lingdong tiltrotator continues to advance intelligent control technology within the China tiltrotator market. One of the key innovations is the rotation attitude locking function, designed to maintain a fixed working orientation regardless of excavator upper-structure movement.

Keeping the Tool Angle Exactly Where You Need It

In real-world applications such as grading with a leveling bar or planer, operators often face a common challenge:

When the excavator upper structure rotates

And the operator does not manually adjust the tiltrotator rotation

The attachment’s working angle unintentionally changes

This results in uneven surfaces, repeated corrections, and increased operator fatigue.

The Lingdong tiltrotator solves this problem with its rotation angle locking function.

How Rotation Locking Works

Once the operator activates rotation locking:

The Lingdong tiltrotator control system continuously detects the wrist’s rotational orientation

Any deviation caused by excavator upper-structure rotation is instantly identified

The system automatically commands the electro-hydraulic proportional valves

Hydraulic flow is precisely adjusted to maintain the original locked rotation angle

As a result, the attachment—such as a grading tool—keeps its exact working direction, even while the excavator cab rotates freely.

Reduced Workload, Increased Safety

By maintaining a constant tool orientation automatically, the Lingdong tiltrotator allows operators to:

Focus on machine movement instead of constant wrist correction

Avoid simultaneous multi-button operations

Reduce operational stress and control errors

Achieve smoother, more consistent grading results

This intelligent assistance is especially valuable in fine finishing work, slope shaping, and precision construction tasks.
