1. Product Introduction
This complete portfolio featuresOEM-matched spare parts exclusively engineered for the LS LANZHOU JC70D drawworks, a heavy-duty core component for land drilling rigs that handles hoisting, lowering, and pipe tripping operations. Every part is cross-referenced to the original factory part numbers, national petroleum industry standards (SY/T, GB, CB series), and dimensional specifications, ensuring zero-modification drop-in fitment and full compliance with API 4F and API 7K drilling equipment standards. This parts catalog covers all critical subassemblies of the JC70D drawworks: drive chains, shafts, sprockets, clutches (high/low/breakout), bearings, bearing boxes, seals, brake systems, air control valves, and gear assemblies.
2. Core Purpose
Core Purpose: These LS LANZHOU JC70D drawworks spare parts serve two critical roles: restoring full operational performance to worn or damaged drawworks assemblies, and supporting scheduled preventive maintenance to extend the service life of the JC70D hoisting system. They provide a standardized, reliable procurement and technical reference for maintaining the drawworks’s torque output, power transmission, braking efficiency, and air control stability under heavy drilling loads.
3. Key Functional Specifications
- Power Transmission: Heavy-duty roller chains (160-2, 160-4, 120-6 series) meet SY/T5595 standards, handling tensile loads up to 120,000 lbs for reliable torque transfer between drawworks components.
- Bearing Durability: Precision tapered roller and spherical roller bearings (32238, 33538, 53536) operate at temperatures from -20°F to 220°F, with service life exceeding 8,000 operating hours under continuous load.
- Clutch Performance: High/low/breakout clutch assemblies (115 series) deliver smooth engagement/disengagement, with friction linings supporting 3,000+ engagement cycles before replacement.
- Brake System Reliability: DBS75 series brake calipers and pads generate static braking torque up to 150,000 ft-lbs, meeting strict rig safety standards for load holding.
- Air Control Efficiency: Quick release and pressure relay valves (QF526D, QY series) provide air response time under 0.2 seconds for precise clutch and brake actuation.
4. Structural & Material Features
All LS LANZHOU JC70D drawworks parts are constructed with field-proven, industrial-grade materials to withstand harsh drilling environments: drive chains use heat-treated alloy steel with anti-wear surface coating; shafts and sprockets feature forged carbon steel with precision machined tolerances (±0.002 inches); bearings utilize high-carbon chromium steel for maximum load capacity; clutch diaphragms and seals use oil-resistant nitrile rubber (NBR) for chemical compatibility with gear oil; brake pads employ interwoven friction material for high heat resistance; air valves and cylinders use corrosion-resistant aluminum alloy. The modular design aligns perfectly with the original JC70D drawworks assembly layout, enabling quick on-site replacement and alignment.
5. Applicable Operating Conditions
These spare parts are optimized for heavy-duty land drilling rigs equipped with the LS LANZHOU JC70D drawworks, performing reliably in high-vibration hoisting operations, ambient temperatures ranging from -10°F to 180°F, continuous 24/7 operation under maximum load, and exposure to drilling mud, gear lubricants, and dust. They are suitable for conventional drilling, workover operations, and deep well drilling rig setups.
6. Maintenance & Care Recommendations
- Scheduled Inspections: Inspect drive chains and sprockets for wear every 200 operating hours; check clutch friction plates and diaphragms every 300 hours; inspect bearings and bearing boxes for lubrication leaks every 400 hours; test air control valves and brake systems monthly for response time.
- Lubrication Protocol: Use extreme-pressure (EP) gear oil (ISO VG 220) for chain and bearing lubrication, replenishing oil every 500 hours; grease clutch and brake pivot points with high-temperature lithium grease every 250 hours.
- Wear Replacement Thresholds: Replace drive chains when elongation exceeds 2%; replace bearings when radial clearance exceeds 0.010 inches; swap brake pads when friction material wears below 3mm; replace clutch diaphragms at the first sign of cracking or air leakage.
- Installation Standards: Torque all bolts and nuts to GB/T5783 standard values; align chains and sprockets to within 0.5mm of parallelism; ensure air valve connections are sealed with O-rings to prevent air loss.
- Storage Guidelines: Store rubber seals and clutch diaphragms in dry, cool conditions away from direct sunlight to prevent degradation; coat metal bearings and shafts with anti-rust oil during long-term storage.

Field Fault Repair Cases (LS LANZHOU JC70D Drawworks)
Case 1: Drive Chain Breakage & Hoisting Failure
A JC70D drawworks experienced sudden hoisting failure due to a broken 160-4X124 drive chain, caused by excessive wear and inadequate lubrication. Installing a new SY/T5595-standard chain and realigning the drive sprockets restored full torque transfer and hoisting functionality.
Case 2: Clutch Diaphragm Air Leak
The high clutch (115.33.00) failed to engage properly, traced to a cracked left diaphragm (115.33.01) causing air pressure loss. Replacing the damaged diaphragm and sealing the connection resolved the air leak, restoring smooth clutch engagement.
Case 3: Bearing Seizing & Shaft Binding
A main drive shaft (106.59.32.00) bound up during operation due to a seized 32238 tapered roller bearing, caused by contaminated lubricant. Replacing the bearing, flushing the bearing box, and refilling with fresh EP gear oil eliminated shaft binding and restored smooth rotation.
