    Correct maintenance method of crawler drilling rig

    Release time:2021-7-13    This article is read 1363 second

    Correct maintenance can better extend the service life of items. Today we will talk about the common sense of crawler drilling rig maintenance.

    The correct maintenance methods of crawler drilling rigs are as follows:


    1. When stopping work in a short period of time, give a small amount of air pressure to prevent sediment from intruding into the drill rig impactor. If the rig is stopped for a long time, the impactor should be lifted 1-2 meters away from the bottom of the hole to fix it.


    2. Always pay attention to check the lubricating oil condition of the wind motor.

    3. When the working surface is immersed in water, use a large-diameter drill bit to insert the drill rod when opening the hole, so that the drill rod is 1-2 meters above the water surface to prevent mud and slag from falling into the hole.


    4. It is not allowed to reverse at noon during drilling operation to prevent the drill rod from falling into the hole;


    5. Always pay attention to check the water and air pipelines of the crawler drilling rig, and whether the bolts and nuts of each accessory are firm.
