In terms of lifting operations, the precision of the 110V single-phase stage hoist is equally impressive, and it can flexibly adapt to different lifting requirements based on the characteristics of props. When it is necessary to lower a vintage crystal chandelier (weighing approximately 80 kg) from the 3-meter-high top of the stage to the ground for storage in a study scene, the hoist monitors the chandelier's load in real time through a weight sensor. Combined with the preset lifting path, it controls the lifting error within 5 millimeters: during the lowering process, if slight air flow interference causes the chandelier to shake slightly, the hoist will immediately activate the dynamic balance adjustment function to fine-tune the traction force and prevent the shaking amplitude from expanding; when it is still 10 centimeters away from the ground, it automatically switches to the "buffer mode", reducing the lowering speed from 0.2 m/s to 0.03 m/s. This not only avoids noise caused by the chandelier base colliding with the ground due to being lowered too much, but also prevents it from occupying space for placing ground props due to insufficient lowering.
When presenting a bustling urban night scene, it is necessary to synchronously lift 20 groups of neon lights with different shapes (each group weighing 30 kg) from the storage slot under the stage to a height of 5 meters in the air, and the height deviation of all neon lights is required to be no more than 3 millimeters to ensure the neatness of the light arrangement. At this time, multiple 110V single-phase stage hoists are linked through a central control system. Each 110V single-phase stage hoist feeds back its own lifting position data to the control system in real time. After comparative analysis, the system sends fine-tuning instructions to the hoists with a deviation exceeding 1 millimeter. This ensures that when all neon lights are lifted to the target height, they not only have a consistent height but also accurately align with the scene markers on the stage floor, forming a perfect coordination with the surrounding high-rise backdrops and street props. When the lights are turned on, neon light strips of different colors interweave into a layered urban night scene, creating a strong visual impact.
