Screw The type hoist is divided into single hanging point and double hanging point according to the number of lifting points. According to the driving mode, it is divided into three modes: manual, electric and flashlight. Its specifications and models include: hand-operated type, closed locking type, side rocking type, Hand-cranked, fully enclosed, direct-connected, flashlight dual-purpose. This product can be used in areas without electricity. The installation and adjustment of the screw hoist and the installation quality of the test machine affect the use effect and life, please user It must be noted that the overall quality of the project (such as the verticality of the gate trough, the quality of the gate installation and the position of the hanging points, etc.) has a direct impact on the installation quality. The user should carefully check the quality of the project before installing the hoist to ensure that it is correct before connecting to the hoist for trial use. . Before the official operation, the following matters should be paid attention to: 1. Remove surface dirt and dust, and add enough lubricating grease to each lubrication point. 2. During installation, the concentricity of the machine and the gate should be ensured, and the error cannot exceed 3. After the machine is installed, run it without load for two periods. Check whether there are any abnormalities throughout the process. 4. During the test run, lift first, check whether each component is deformed, and whether the gate slides in the door slot. After confirming that there are no errors, continue to lift. Every lift. Check again. When debugging the hoist and without load, ensure that the unbalance of the three-phase current does not exceed positive and negative, and measure the current value. . Adjustment of the upper and lower limits: When the gate is in a fully closed state, press the upper limit switch against the upper limit switch and fix it on the screw. When the gate is fully open, press the lower limit plate against the lower travel switch and fix it on the screw. . The adjustment of the hoist's master controller must ensure that the error does not exceed the upper and lower limits when the gate is raised and lowered. . After installation, a trial run must be carried out. A no-load test is performed, that is, let the screw make two strokes, listen for any abnormal sounds, and check whether the installation meets the technical requirements. Second, perform a load test. Under the rated load, perform two strokes to observe the operation of the screw and the gate to see if there are any abnormalities. Only after confirmation can it be officially launched. , the operator must master the structure, performance and operation method of the hoist, and have certain mechanical knowledge to ensure the normal operation of the machine. . Before operation, conduct a comprehensive inspection of the lifting and shutting down machine to see if all parts are well lubricated and whether the bolts are loose. When electric opening and closing, check whether the power line is connected and whether the switch is in good condition. , During electric operation, the operator is not allowed to leave the site, and if any problem is found, stop the machine immediately. . When starting and shutting down the machine for maintenance, the load must be removed. . During use, lubricating oil needs to be injected from the oil injection hole at any time, and sufficient lubricating oil must be maintained at all times. The screw must be regularly cleaned of grease and coated with new oil to prevent corrosion.
