Are these parts compatible only with Z05012100001AA Rotary Table Area for ZJ40 Truck-mounted Drilling Rig? Can they be used for fixed ZJ40 rigs?

All parts are exclusively matched to Z05012100001AA Rotary Table Area for ZJ40 Truck-mounted Drilling Rig. They cannot be directly used for fixed ZJ40 rigs, as truck-mounted rigs have lighter, more compact structural designs, and component dimensions, load-bearing capacities, and connection positions differ from fixed rigs. Using these parts for fixed rigs will cause installation mismatch and safety hazards. For fixed ZJ40 rigs, provide the specific rotary table area model, and we will offer matching parts.

What maintenance is required for the rotary table area parts before and after rig relocation (a key scenario for truck-mounted rigs)?

Before relocation: 1. Inspect all safety pins, welding chains, and connection bolts for tightness; re-tighten if loose; 2. Check hoisting components (lifting ring, pad eye) for damage; 3. Clean drilling fluid residues and apply anti-rust grease to metal components. After relocation: 1. Re-inspect all components for displacement or damage caused by vibration; 2. Check the rotary table area’s levelness and adjust if needed; 3. Lubricate rotating components (rotating shaft) and connection points to ensure smooth operation.

How to choose between genuine parts and non-genuine parts for the rotary table area, and what risks are there with non-genuine parts?

We strongly recommend using genuine parts, as they comply with API Spec 8C and original equipment standards, ensuring compatibility, load-bearing capacity, and durability. Non-genuine parts often use inferior materials, have imprecise machining, and fail to meet safety standards—risks include: 1. Component deformation or cracking under load, leading to rotary table failure; 2. Poor compatibility causing installation mismatch and vibration; 3. Short service life, increasing maintenance frequency and downtime; 4. Safety hazards (e.g., safety pin breakage, lifting ring failure) that may cause equipment damage or personnel injury.
