As a core lifting device for stage construction, equipment installation and commissioning, and performance processes, the operational safety and stability of stage electric hoists are directly related to the progress of stage projects, the smooth running of performances, and the life safety of on-site personnel.
Voltage compatibility is a fundamental prerequisite for the normal startup and stable operation of stage electric hoists and must never be overlooked. When using stage electric hoists in a stage setting, operators must first carefully consult the equipment manual to clarify the rated voltage parameters of the device (common specifications include single-phase 220V and three-phase 380V), and then match them with the actual voltage of the on-site power supply system. Meanwhile, it is essential to inspect in advance the load capacity of the power supply lines and the firmness of line connections, so as to avoid equipment malfunctions such as startup failure and motor burnout due to overheating caused by aging lines, poor contact, or unstable voltage. It is recommended that before official use, professional voltage detection tools be used to measure the on-site voltage multiple times, ensuring that the voltage fluctuation range is controlled within the ±5% tolerance allowed by the equipment. If the on-site voltage fails to meet the requirements, auxiliary devices such as voltage stabilizers should be equipped in a timely manner, and the equipment should only be started after the voltage has stabilized.
