This long-distance suspension characteristic causes a significant inertia effect when trying to adjust the hook position. The inertia effect makes the hook prone to unpredictable swings and shakes during movement, which significantly increases the difficulty of achieving precise position adjustment. Therefore, when facing high-precision hoisting requirements, traditional hook systems often find it difficult to achieve ideal control effects. Utility Model Content
