Precision Placement and Rotation of Subsequent Blocks

What happens here
As the wall construction progresses, the excavator operator demonstrates the advanced capabilities of the tilt-rotator. When a stone block needs to be placed with a different orientation, the operator simply grips it with the Hydro Gripple, then activates the tilt-rotator function to rotate the block 180 degrees horizontally in mid-air. This eliminates the need for manual repositioning on the ground, saving significant time and effort. The block is then carefully lowered and positioned adjacent to the previously placed stones. A worker is visible on-site, using a spirit level to check the horizontal and vertical alignment of the newly placed blocks, ensuring the wall remains level and plumb. The base beneath the stones appears to include black geotextile fabric, which helps prevent soil migration and aids in drainage.
Goal: Accurately position and align all stone blocks, adjusting orientation as needed.
