Introduction
The audible & visual rotating warning light consists of a rotating lampshade, light source (halogen/LED), buzzer/horn, drive motor and base, fixed to the crane end beam, trolley frame or electric hoist housing via bolts. When the crane operates, the warning light synchronously lights up, the motor drives the lampshade to rotate, forming a 360° continuous flashing beam, while the buzzer emits intermittent or continuous alarm sound, reminding ground personnel of safety from both visual and auditory aspects. Models with LED light source offer long life, low power consumption and fast response; the lampshade adopts polycarbonate (PC) material with impact resistance, aging resistance and high light transmittance. The base has a built-in drive circuit and wiring terminals for easy installation and wiring. Widely used in various lifting machinery, automated production lines, ports and docks, serving as an essential device for lifting operation safety warning.
Our Advantage
Simultaneously outputs 360° rotating flashing light and high-decibel alarm sound, dual visual and auditory reminder, effectively attracting surrounding personnel’s attention even in noisy workshops or visually obstructed environments, greatly improving operation safety.
Motor-driven lampshade rotates at high speed, forming 360° omnidirectional continuous light beam with visible distance of 50~100m, wider coverage than ordinary fixed warning lights, allowing personnel at any ground angle to clearly see the warning signal.
Buzzer/horn outputs 90~130dB volume with strong sound penetration, clearly audible even in high-noise environments such as metallurgy, foundry and ports, effectively covering all personnel within the crane operating radius and avoiding accidents due to inaudible warnings.
Adopting high-brightness LED light source with service life over 50,000 hours, 10 times that of halogen lamps; low power consumption, fast response and good shock resistance, requiring no frequent bulb replacement during long-term use with extremely low maintenance cost.
Base with mounting holes and wiring terminals, fixed via bolts; supports multiple voltage specifications DC24V, AC110V, AC220V, AC380V, compatible with 0.5t~100t various cranes and electric hoists, convenient for both new installation and renovation.
