Rig construction, rig must always do the following aspects of routine maintenance: 1, before class work must include references to the drill unit (linker rope), add butter; Note: to lift one end of the lead When the butter must take the other end of the nozzle oiling grease fittings unscrewed. This is conducive to the note previously forced out of butter. Conversely may include references Lane will squeeze bad seal large drilling rig where to sell, dirty water containing sand, mud is very easy to enter, it will reduce wear bearing mention cited the sensitivity. Note: You have a new and improved large-scale drilling rig introducer mention how much maintenance mode please consult SANY Customer Service Department. 2, the class before work must follow to drill guide body (the drill stand) bearing butter filling; 3, always check the wire rope is intact; 4, always check the breakage of the tubing, seals and a large drilling rig, ready meet the urgent need of spare parts; 5, pay attention to the circuit relay is aging, early preparation of spare parts; 6. Check drill include references devices (rope connector) bearing rotation is flexible, should be immediately replaced if damaged; 7, always check the bolts, whether pin wear, fracture, if damaged should be replaced immediately. Drilling rig construction process should comply with the rules: 1. The formal application before the drill, should check whether the power supply capacity required for rig capacity. 2. Use the instructions required to check the circuit, the voltage range, leakage protection switch and operating handle. 3. formal application drilling rigs should slow down, align the drill holes, when the current pointer favor no-load condition, began to drill holes. The drilling operation process, should always observe the meter, such as when more than the rated current, should slow speed drill. 5. To prevent motor overload large drilling rig manufacturers in the control box is set overcurrent relay; after the overcurrent relay, should be spaced about 10min restart, restart, it should not be contained within 30min of another. 6. Use should avoid relying inching instantaneous of forward and reverse. 7. When the rig operation, should prevent the cable being entangled drilling have someone care. 8. Operation To change the rotation direction of the drill pipe, drill pipe, etc. shall complete stop before starting.
