Debugging of the opening and closing machine:

1. When the hoist is unloaded, ensure that the three-phase current imbalance does not exceed plus or minus 10%, and measure the current value.  

2. Adjustment of upper and lower limits: When the gate is fully closed, press the upper limit switch tightly and fix it on the screw. When the gate is fully open, press the lower limit plate down on the travel switch and fix it on the screw.  

3. The adjustment of the main controller of the hoist must ensure that the error of the gate lifting to the upper and lower limit positions does not exceed 1cm

4. After installation, it is necessary to conduct a trial run. First, conduct a no-load test by letting the screw travel twice and listening for any abnormal sounds to check if the installation meets the technical requirements. Conduct a load test, perform two strokes under rated load, observe the operation of the screw and gate, and check for any abnormal phenomena. Only after confirming that there are no errors can it be officially put into operation.  

1. Operators must master the structure, performance, and operation methods of the hoist, and have a certain level of mechanical knowledge to ensure the normal operation of the machine.  

2. Before operation, conduct a comprehensive inspection of the hoist to ensure that all parts are lubricated properly and that the bolts are not loose. Check if the power circuit is connected and if the switch is in good condition during electric opening and closing.  

3. During electric operation, the operator must not leave the site and immediately stop the machine if any problems are found.  

4. When repairing the hoist, the load must be removed.  

5. When in use, lubricating oil should be injected through the oil injection hole at any time, and sufficient lubricating oil should be maintained regularly. The screw should be regularly cleaned of oil stains and coated with new oil to prevent rust and corrosion.
