Construction elevator accessories are used to connect two shafts of different organizations, so that they have mutual rotation, transmission torque mechanical parts. Because it has the effect of load-bearing force, it is very easy to damage in the whole process of application, thus reducing its service life.

　　Construction elevator accessories damage has the following reasons:

　　1. Environmental elements. When placing construction elevator accessories, it is necessary to check whether the surrounding environment is dry, with wood and organic chemicals. If the natural environment is wet and cold, it will rust the construction elevator accessories and endanger the actual application effect and service life of construction elevator accessories.

　　2. Human error. In the application of construction elevator accessories, we should pay attention to the model and specification of construction elevator accessories. If the inappropriate model and specification will endanger the application of construction elevator accessories, in addition, the equipment will also be endangered.

　　3. Connect the anchor bolts. Connecting anchor bolt is the key component of construction elevator accessories. If the connecting anchor bolt is not used properly, it will immediately endanger the service life of construction elevator accessories.

　　4. Damage elements. Construction elevator accessories are the connecting parts between different equipment, so there will be some damage in the whole process of application. Long term application will cause deep damage to construction elevator accessories, and then cause damage to construction elevator accessories.

　　5. Fracture elements. Construction elevator accessories in the wrong operation or use for a long time, will appear the condition of rupture. Therefore, I want to carry out maintenance, to broaden the service life of construction elevator accessories.

　　The installation deviation of construction elevator accessories should be strictly controlled, and the general installation deviation should not exceed half of the compensation. It is necessary to regularly check the operation status of construction elevator accessories, the alignment status of construction elevator accessories, and the relative displacement can not exceed the amount of compensation. To minimize the relative displacement, can reasonably broaden the service life of construction elevator accessories.

　　Regularly carry out moistening of construction elevator accessories, check the remaining oil, quality and sealing condition of grease, and fill and replace them if necessary.

　　For the construction elevator accessories on the high-speed operation mechanical equipment, it is necessary to go through the balance test, and carry out the assembly according to the identification, and strictly limit the net weight in the middle of the connecting anchor bolt.
