Are all these accessories fully compatible with the SJ ZJ40 Truck-mounted Drilling Rig raising lines (Z07030000002AA)?

Yes, all accessories are specially designed and produced for the SJ ZJ40 Truck-mounted Drilling Rig raising lines (model: Z07030000002AA). Each part’s model and size strictly match the original equipment, ensuring perfect compatibility. They also comply with API 6D and SAE J517 standards, guaranteeing stable connection, tight sealing, and reliable operation in mobile drilling scenarios.

2

How often should key wearing parts (hoses, pipe clamps, fasteners) be replaced for the raising lines of a truck-mounted drilling rig?

Due to the mobile nature (frequent vibration during transportation) and outdoor harsh environment, the replacement cycle is shorter than that of fixed drilling rigs: hose assemblies every 12 months, pipe clamps and rubber gaskets every 6 months, fasteners (bolts, nuts, washers) every 8-10 months. For parts with severe wear (caused by frequent transportation or harsh conditions), replace them immediately to avoid failure.

3

What maintenance work should be done on the raising lines before and after road transportation of the SJ ZJ40 truck-mounted drilling rig?

Before transportation: 1. Check all fasteners, fittings, and pipe clamps for tightness and tighten if needed; 2. Fix hoses and steel pipes firmly to avoid displacement; 3. Inspect the pipeline surface for damage. After transportation: 1. Recheck all connections for loosening or leakage; 2. Inspect hoses and pipe clamps for wear caused by vibration/friction; 3. Clean the pipeline surface and check for corrosion, replacing worn or damaged parts in time.
