AI Technical Summary
Existing window cleaning machines have complex swing arm structures, poor swing flexibility, small swing angles, and high difficulty in bending the rails.
The swing arm adopts a heavy-duty simple structure, including structural components and a rotating shaft. The rotating shaft is mounted on the structural components and uses components such as upper and lower oilless bearings and lock nuts to achieve stable connection and flexible swing of the rotating shaft.
The swing arm features a simple structure, high flexibility, and a large swing angle, ranging from -10° to 90°. It is also easy to install and is particularly suitable for curved tracks with small turns.
