1.Bucket elevators must be firmly installed on solid concrete foundations. The surface of the concrete foundation should be flat and in a horizontal state to ensure that the bucket elevator meets the verticality requirements after installation. For bucket elevators with a relatively high height, the middle and upper casings should be connected to the adjacent buildings (such as silos, workshops, etc.) at appropriate positions to increase their stability. During installation, first install the lower components and fix the anchor bolts, then install the middle casing, and finally install the upper casing. After the casing is successfully installed, correct its verticality. Measure it with a plumb line from top to bottom of the whole height, and the error should be less than 10 mm. The upper and lower shafts should be parallel, and their axes should be in the same plane. When installing a bucket elevator with a relatively low height, the upper, middle and lower casings can be completely connected and properly aligned on the ground level, and then the whole assembly can be hoisted vertically and fixed on the concrete foundation.

2. After the casing is installed, install the chains and buckets. The U-shaped screws used for connecting the buckets are both the joints of the chains and the fixing parts of the buckets. The nuts of the U-shaped screws must be tightened firmly and reliably locked to prevent loosening. 

3. After the chains and buckets are installed, properly tension them. 

4. Add an appropriate amount of engine oil and grease to the reducer and the bearing housing respectively. The reducer is lubricated with industrial gear oil. Either calcium-based or sodium-based grease can be used in the bearing housing. 

5. Trial operation: An empty-load trial operation should be carried out immediately after the installation is completed. During the empty operation, attention should be paid to the following points: Reverse rotation is not allowed, and there should be no collision phenomenon. The empty operation should last for no less than 2 hours, and there should be no overheating phenomenon. The temperature rise of the bearings should not exceed 25 °C, and the temperature rise of the reducer should not exceed 30 °C. After 2 hours of empty operation, if everything is normal, a load test can be carried out. When conducting the load test, the feeding should be even to prevent excessive feeding and blockage at the bottom, which may cause a "stalled" accident.
