The arrangement of the spiral elevator should use a level instrument. The parallelism between the lifting system and the guiding machinery needs to be carefully confirmed. When it is installed and used in a narrow place, its rotation should be detected. It is driven by hand. During the complete operation of the system, the force should be easy and stable. Before the trial operation, the screw rod must be cleaned. If it is possible to spray grease on the whole stroke.
In the initial test of worm gear lead screw elevator, the lifting system should not be loaded. If there is no problem in the initial test, the load can be increased gradually. It is necessary to pay attention to the matching between the speed of the lead screw shaft and the load carried. Radial calibration should be carried out for the allowable load, allowable external load, and allowable rotation speed of the lead screw shaft of the elevator, If it exceeds the product data, it will cause serious damage to the whole elevator equipment. While loading, check the temperature rise of any hot spot and gearbox. When the elevator is working, the surface temperature of the reducer should be controlled in the range of - 15C ° to 80C ° to ensure that the surface temperature of the movable nut is also in the range. Check the reliability of limit switch and all connecting bolts. After running for a period of time, all fixed bolts must be re tightened. Under extreme operating conditions, the wear of nut (worm gear) must be checked at a shorter time interval for screw hoist. The clearance of thread is mainly checked. The specific time depends on the power on time.
