||
| سلك حبل | 2. | ⑴Serious corrosion, pitting, pitting, formation of grooves, loose or broken strands of outer steel wire should not occur; ⑵Whether the fixed parts of the wire rope are in danger of loosening, and there should be no lack of oil or gnawing at the contact parts of the pulley and balance wheel Troubles such as rope, slipping, etc. |
|||
| Braking device | 3. | ⑴The brake wheel has no cracks (not including the microcracks in the hardened layer of the brake wheel surface); ⑵There is no friction between the brake wheel and the friction plate when the brake is opened, and the brake wheel and the friction plate contact evenly when the brake is closed, which does not affect braking Defects in performance and oil pollution; ⑶ The brake is adjusted appropriately, and the brake is stable and reliable; |
|||
| reel | 4. | ⑴Whether there are cracks (especially in the middle part); ⑵Whether the rope guide is broken; ⑶Whether the rope groove is worn; when the wall thickness of the drum is worn up to 20% of the original wall thickness, or when the wire rope skips frequently, it should be scrapped reel. ⑷Whether the cylinder shaft is worn; ⑸Whether the screws on the two ends of the web are fastened, and no cracks appear on the web; |
|||
| المخفض | 5. | ⑴Check the gear transmission, whether there are abnormal noises during operation; ⑵The vibration of each bearing part; whether there is abnormal vibration; ⑶ Whether the oil temperature is normal; whether there is oil leakage phenomenon; whether the oil level position is normal; |
|||
| wheel | 6. | ⑴Wear inspection: No abnormal wear on the wheel tread and the inner surface of the rim; ⑵Crack inspection: No abnormal cracks on the surface of the wheel. |
|||
| Safety protection device | Stopper | 7. | ⑴ Whether the limit switch is sensitive, safe and reliable; whether the contact of the switch is damaged or worn. ⑵ Check whether the wiring fixing and connecting bolts are loose. ⑶ The hook pulley group is lifted to the upper limit position, and the lifting limit switch should be able to act immediately |
||
| الزائد المحدد | 8. | Whether there is an overload limiter, when the alarm setting is reached, it should be able to detect the alarm and disconnect the ascending loop | |||
| 9. | The shock absorber is installed firmly, no damage to the protective cover and other protective devices |
