Operating Procedures for Attached Plate Vibrators 1. Attached and plate-type vibrator bearings should not be subjected to axial forces. During operation, the motor bearings should remain horizontal. 2. When using multiple attached vibrators simultaneously on a formwork, the frequencies of each vibrator should be consistent, and vibrators on opposite sides should be staggered. 3. Before operation, attached vibrators should be inspected and tested. Test vibrations should not be performed on dry, hard soil or hard objects. Vibrators installed on mixing plant silos should be fitted with rubber pads. 4. During installation, the mounting bolt holes on the vibrator baseplate should be positioned correctly to prevent the base bolts from twisting and damaging the housing. The base bolts should be tightened, and the tightening of each bolt should be consistent. 5. During operation, lead-out cables should not be overtightened or short-circuited. During operation, the ground leakage protector and grounding or neutral connection devices of electrical equipment should be inspected and confirmed to be in compliance. 6. Attached vibrators should be installed on concrete formwork. Each vibration cycle should not exceed one minute. Vibration should be stopped when the concrete is flowing or level within the formwork. Vibration should not be resumed until the concrete is initially set. 7. The formwork of the component on which the vibrator is installed should be strong and secure, and its area should be equivalent to the vibrator's rated vibration area. 8. When operating a flat-plate vibrator, the plate should maintain contact with the concrete to ensure that the vibration waves effectively compact the concrete. Once the concrete has slurry on the surface and has stopped sinking, the vibrator can be slowly moved forward at a speed sufficient to ensure that the concrete is compacted and slurry is released. The vibrator should not be left on set or initially set concrete while in operation.
