Winch, column guide rail, slewing mechanism, slewing brace, slant support adjusting mechanism, carrier sprocket, idler and driving wheel bracket shall be checked regularly and lubricated regularly.

1. Winch, column guide rail, slewing mechanism, slewing brace, slant support adjusting mechanism, carrier sprocket, idler and driving wheel bracket shall be checked regularly and lubricated regularly.
1.1 The copper sleeves at both ends of the main winch drum should be lubricated daily.
1.2 The carrier roller, guide wheel, and drive wheel should be lubricated at least once a week, and the track should be idle when filling.
1.3 The exposed gear, column guide rail, slewing support, slant support lead screw and hydraulic system of the main winch shall be checked every day, and the lack of timely filling of lubricating grease and hydraulic oil.
2. Wire and cable joints, oil pipe joints, and areas prone to collision and friction should be protected with sleeves or protective tubes.
3. During work, carefully check the power head, vibration hammer flange bolts, and running mechanism bolts and nuts for looseness every day:
4. When working, pay attention to whether the ball socket under the lead screw moves up and down every day. If it does, stop working immediately. Remove the end cover of the ball socket that extends out of the beam to make the diagonal brace under pressure. Tighten the lower nut and lock it. If necessary, weld the nut firmly with electric welding. When the temperature drops below zero in winter, it is necessary to check for any accumulated water in the extended beam. Any accumulated water should be promptly removed to prevent freezing and loosening of the nut.
5. When the diagonal brace rotates, pay attention to observe whether there is swing. If there is swing, replace the guide copper sleeve or copper nut in the diagonal brace in time.
