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, Tengxian 50 type drilling rig, began to drill holes. The drilling operation process, should always observe the ammeter, 50 type drilling rig where to sell, such as when more than the rated current, should slow speed drill. 5. To prevent motor overload in the control box is set overcurrent relays; later, after the overcurrent relay, 50 type drilling rig prices, should re-start interval of 10min, 50 type drilling rig manufacturer, restart, within 30min of not another carrier. 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. Drilling rig should always check the item 1, the end of the steel cord to conduct inspections of consolidation; the contents of the wire rope inspection is: wire rope safety defect inspection turns, wire selection, installation, lubrication, wire rope, wire rope diameter and wear as , quantity broken wire rope; 2, ready to rig pulley systems checks, mainly check the project: the pulley body condition, transition pulley anti-skipping devices; 3, ready to rig running system checks, mainly check the project: pile machine with tubes, pallets and hook pipe system status, laying sleepers; Yongfu County 50 type drilling rig, where to sell 50 type drilling rig, provided by the Luoyang Prius Prius Drilling Equipment Co., Ltd.
