How to install and adjust screw hoists

Before installation, it is necessary to check whether each component is excellent, whether the lubricating grease is sufficient, whether the anchor bolts are loose, and whether the relevant technical statistical data between the two match.

During installation, it is necessary to maintain a basic layout plan level of 180 °; The total contact area between the gate opening and closing machine base and the basic layout plan should exceed about 90%; The centerline of the screw rod should be perpendicular to the sea level of the load-bearing beam on the dividing platform; It should be aligned vertically with the lifting ear hole of the gate to prevent the screw rod from tilting, which may cause partial support and damage to the parts.

After installation, it is necessary to conduct a trial run. One is to conduct a no-load test, which involves arranging the lead screw for two strokes and listening for any abnormal sounds to verify whether the installation meets technical standards. Conduct a second load test, arrange two trips under the rated load, observe the operation of the screw rod and water gate, and check for any abnormalities. Once the accuracy is confirmed, the operation can be announced. After a period of load operation, initial maintenance and upkeep should be carried out to clean the metal material foam caused by conflicts between new parts of the body, such as screws, nuts, boosters, and vortex rods, gently and neatly, apply lubricating grease, seal tightly, and reuse.
