电动葫芦的经常故障可能是长时间存储和高频率使用导致的，是否由于电动葫芦设计不当或者是制造问题引起需要深入调查分析后才能有结论。如果基于现况和赶工需求增购一台电动葫芦备用，工程部对此不反对。请项目经理从项目管理角度做决定即可。翻译成英文

The frequent failures of the electric hoist may be caused by long-term storage and high-frequency use. Whether they are due to improper design or manufacturing issues requires in-depth investigation and analysis to draw a conclusion. If, based on the current situation and the need for rush work, an additional electric hoist is purchased as a spare, the engineering department does not object. The project manager can make a decision from a project management perspective.
