An automatic cycle uses cable tension or visual detection to remove excess concrete from diaphragm wall shuttering planks while reducing operator strain and machine wear.

An automatic rolling-in device keeps the loading shovel upright during lifting, limiting cargo spillage and stabilizing the load.

Positive-flow prioritization can destabilize combined boom-arm motion; adjusted arm-cylinder velocity estimates keep region limiting control stable.

Position, attitude, and rotation sensing keep automatic switching aligned with operator intent during slope formation and target-shape construction.

A contact-actuated slider blocks the pin during misalignment, preventing false coupling indications and reducing operator checks.

A pin-on tube and pivot-bar assembly extends mini-excavator reach without repositioning, saving time and protecting sod.

Real-time compaction feedback replaces assumed 100% compaction, helping work machines avoid unnecessary passes and adjust attachment movement.

The controller drives an actuator to bring the grader blade toward neutral, easing accurate positioning for less-experienced operators.

Spherical joints accommodate misalignment and absorb impact, reducing wear during mining shovel dipper door release.

Contact, posture, and contour detection set the bucket locus while segmented calculations preserve excavation precision and limit processing load.

An upper and lower pipe connection, insertable pole, and hook secure multiple excavator buckets to the backfill blade, reducing manual handling and transport time.

A boom and wheeled frame use the loader’s tilting plane to create mechanical advantage, extending reach while reducing hydraulic cylinder load.
