If power equipment is damaged, it will have an impact on people's daily life, continuous industrial production, and the normal operation of society. Workers need to conduct regular inspections of power equipment and carry out repairs in a timely manner if any safety hazards are found. It is more convenient to repair when the hazard location is low, but when the hazard location is high, workers need to use auxiliary tools such as ladders and lifting platforms to carry out maintenance work.
[0003] When staff inspect and repair power equipment, they generally need to carry various tools, which are relatively heavy. If there are any tools that are missed or replaced, they need to repeatedly go up and down to get them, which is troublesome, affects work efficiency and causes damage to auxiliary tools. When it is necessary to replace parts of power equipment, if the parts are heavy, it is extremely inconvenient for staff to carry them. Simply placing them on the top plane of the lifting platform in the prior art will seriously hinder the staff's movements and affect the range of activities and safety of the operators. If a lifting platform with a larger top plane is selected or a special loading platform is added next to the lifting platform in order to meet the loading needs while ensuring the activity space for personnel, it will seriously affect the flexibility and passability of the lifting platform during use, which is not conducive to actual use.
