Common fault classification of stage electric hoists

　　As the name suggests, the stage electric hoist is a light and small lifting equipment commonly used in stages or large-scale activities. During use, a series of problems such as disorderly venues or negligence of staff may cause the stage electric hoist to malfunction or be damaged. If we classify its faults according to types, what are the faults of the stage electric hoist?

　　One is a sudden malfunction, which often occurs suddenly and catches people off guard. This type of malfunction often causes significant damage, such as sudden breakage of chains and hooks, burning of motors, and so on; The second type is progressive failure, which often manifests as a gradual decline in the performance of stage electric hoists. Common manifestations include wear, fatigue, aging, etc., and ultimately, due to low efficiency and frequent failures, they are eliminated. Progressive failures can also be prevented through regular testing and maintenance.

　　The above is the common fault classification of stage electric hoists. In daily use, we should operate and maintain according to regulations and instructions, which can reduce the occurrence of these two types of faults.

　　The stage electric hoist requires preventive maintenance

　　With the development of technology and the continuous improvement of productivity, the level of mechanical automation is also constantly improving. Special light and small lifting equipment, stage electric hoists, are used as construction tools in stage construction, playing an important role in our stage construction. Of course, the more automated the mechanical equipment, the higher the maintenance requirements, and the corresponding increase in technical requirements for maintenance personnel.

　　During the process of using stage electric hoists, various malfunctions may occur due to the unfamiliarity of operators with stage electric hoists, unintentional misoperation, and inadequate maintenance, which not only affects work efficiency but also leads to an increase in maintenance costs.

　　Therefore, in order to reduce the occurrence of such phenomena, we need to carry out preventive maintenance on the stage electric hoist. Before any malfunctions occur, hidden dangers should be eliminated to minimize the failure rate of the stage electric hoist and ensure the efficient and safe operation of the equipment.
