Some construction elevator maintenance personnel on the construction site do not timely eliminate the fault that causes the action of overvoltage and undervoltage wrong phase break protection device, but cancel or short-circuit the protection device, so that it does not work, leaving hidden trouble for the equipment. Some early products do not have the protection device at all, so it is recommended to equip it. The construction elevator shall be able to carry people and goods under the condition of reliable and effective protection devices for over-voltage, under voltage and phase staggering.
1. The important preparation work to support the operation of lifting platform should choose a flat surface. If the foundation is soft or uneven, the work can only be carried out after corresponding treatment.
2、在升降平台旋转操作过程中，必 须要在下臂起升高度前旋转，缓缓转动，而剪切臂和一个平台，各种设备的距离是否满足安 全需求。任何国家或行业法规相抵触的地方，按国家或行业规定。
2. During the rotation operation of the lifting platform, it must rotate slowly before the lifting height of the lower arm, and whether the distance between the shear arm and a platform and various equipment meets the safety requirements. Where any national or industrial regulations conflict with each other, the national or industrial regulations shall prevail.
3. The operator of working platform shall wear safety belt. In the field of live working, the platform shall be lifted according to the regulations. The lifting operation shall be under the command of the person in charge.
4. Elevator power system does not start, this is common in the obvious switch did not start, this is also a problem that many people easily ignore.
5. Screw too loose or too tight, this problem is generally not found, but there is a big safety problem, so in the daily use of the lift, we must pay attention to, pay attention to safety.
As a kind of construction machinery, the construction elevator is widely used in construction because of its simple structure, fast lifting and stable transmission. With the continuous increase of high-rise buildings, the use of elevators is also growing rapidly, which leads to frequent malignant accidents. The main reason is the lack of scientific management and effective preventive measures.
Construction elevator safety as a very old topic, but repeatedly with the way of death, awaken people to pay attention to it. Although it is no longer a problem from the concept to the system, from the supervision to the implementation, it always breaks through the security line from the weak link of prevention and the place easy to neglect. The frequent occurrence of construction elevator accidents shows that there are still great deficiencies in its safe use.
