Exclusive Adaptation to Audio Scenarios with Outstanding Hoisting Precision

The audio manual chain hoist is a lifting tool tailor-made specifically for hoisting audio equipment in the field of audio engineering, rather than a general-purpose manual chain hoist. Its core advantage lies in the in-depth optimization of internal gear transmission ratios and chain traction structures, targeting the weight distribution characteristics (e.g., line array speakers are strip-shaped with offset centers of gravity; heavy-duty subwoofers have concentrated single-point load-bearing) and installation process requirements (e.g., suspension angles must match sound field coverage; multi-unit speakers require height alignment) of different types of equipment such as line array speakers, heavy-duty subwoofers, and professional coaxial speakers. Equipped with high-precision displacement sensors and scaled positioning rulers, it can achieve millimeter-level (±1mm) lifting and positioning adjustment.

During operation, the audio manual chain hoist can precisely control the suspension height, horizontal angle, and vertical plumbness of audio equipment by pulling the chain at a constant speed. It not only ensures that multiple groups of line array speakers are arranged in an accurate arc to achieve uniform sound field coverage but also enables heavy-duty speakers to accurately align with suspension points to avoid center-of-gravity offset. This fundamentally eliminates problems such as sound field imbalance (e.g., excessive/insufficient volume in certain areas), equipment resonance noise, or structural loosening caused by installation deviations, perfectly meeting the rigorous standard in audio engineering that "millimeter-level precision determines sound field quality" and providing a fundamental guarantee for the performance of professional audio systems.
