AI Technical Summary
Existing cranes lack structures to prevent excessive cable swaying, resulting in excessive cable swaying, which increases the risk during lifting and requires non-standard motor requirements, increasing costs.
The system employs a combination of cable reel, shaft, photoelectric encoder, light source, grating disk, photosensitive element, cable, and frequency converter. The photoelectric encoder detects the rotation speed of the cable reel, and combined with anti-sway brackets, damping rods, pulley frames, and anti-derailment baffles, it prevents cable swaying and reduces risks.
It enables precise detection of cable length, reduces non-standard requirements for motors, reduces cost investment, and effectively prevents cable swaying, thereby reducing the risk during the lifting process.
