Electric hoists represent their own machinery, strength, and toughness, while the stage is elegant, flowing, and soft, with conflicts and collisions between the two.

Product Name: W12 Stage Electric Hoist
The power supply frequency used by the electric stage hoist for truss usually closely matches the mains frequency of the region where it is located. In Mainland China, the mains frequency is stably maintained at 50Hz. Correspondingly, for the stage electric hoists produced and used locally, both the design and manufacturing processes are centered around 50Hz.
The impact of the power supply frequency on the operation of the electric stage hoist for truss should not be underestimated. The rotational speed of the motor of the electric hoist has a positive correlation with the power supply frequency. When the power supply frequency is higher than the rated value, the rotational speed of the motor increases, causing the lifting and lowering speed of the electric hoist to far exceed the expected level. When the power supply frequency is lower than the rated value, the rotational speed of the motor decreases, resulting in the slow lifting and lowering of the electric hoist, which seriously affects the progress of the performance. In order to cope with the differences in power supply frequencies in different regions, some large-scale stage equipment rental companies will purchase electric stage hoists for trusses that support broadband operation. This type of equipment can operate stably within a certain frequency range and has strong adaptability. During the preparation stage of transnational performance events, stage technicians will carefully check the rated frequency of the electric stage hoist for truss and make corresponding adjustments and optimizations to the equipment according to the mains frequency of the performance location to ensure the smooth progress of the performance.
