Along the way, the team members of a long time to calm the high-speed railway Weifang section construction of a rusty XR220 rotary drilling rig and user Wu story.
In August 2008 to buy the XR220 rotary drilling rig, work has been more than two hours to now. After the maintenance of the team members, they chatted with the machine hands and the scene manager.

I will according to your operation and maintenance manual lubrication bearing, check the bolt and nut tightening situation, hydraulic oil, gear oil, filter element will regularly change regularly, engine regular maintenance. When we operate the machine, we are also careful, not use brute force when dumping the soil, although the construction efficiency is affected by a little, but it extends the service life of the handle, and it is also a kind of protection to the hydraulic system."
