Many users fall into the cognitive misunderstanding that "the same structure means consistent performance" when selecting stage electric hoists. They think that since they are all stage electric hoists, with internal components such as motors, chains, and gearboxes, they can just choose any one at will. However, in reality, this idea completely ignores the diversity of stage performance scenarios and the importance of equipment adaptability, which is likely to result in selecting equipment that cannot meet the actual application needs, or even lay hidden safety hazards.
First of all, the performance requirements of stage electric hoists vary greatly in different performance scenarios. For example, for musical performances in small theaters, the hoisting load is relatively small, the frequency of scene switching is moderate, and there is a high requirement for the mute effect of the equipment; while for large-scale outdoor concerts, New Year's Eve galas, etc., it is often necessary to hoist heavy lighting frames, large LED screens and other equipment, which have higher requirements for the rated load, lifting speed, and wind resistance (for outdoor scenarios) of the equipment. At the same time, the working class of the stage electric hoist (i.e., the comprehensive index such as the frequency of use and load state of the equipment) directly determines its applicable scenarios. Equipment of different working classes have obvious differences in the design of core components such as motor power, gear strength, and braking performance. If the selection is not based on the actual application occasion and working class, it will at least lead to overload operation and frequent failures of the equipment, and in severe cases, cause safety accidents.
