AI Technical Summary
Traditional dance barre height is fixed or manually adjustable, which is inconvenient and cannot adapt to different heights and training needs, thus limiting the flexibility and effectiveness of training.
It adopts a hydraulically adjustable lifting dance barre, which realizes automatic adjustment of the barre height through a hydraulic control system, including a hydraulic pump, relief valve, three-position four-way directional valve, oil tank, oil filter and throttle valve, and achieves precise adjustment in combination with the control panel.
It enables precise adjustment of the height of the ballet barre to meet the needs of dancers of different heights. It is easy to operate, highly safe, and the adjustment process is smooth and precise.
