YG225 & YG160 Series Full Spare Parts for Drilling Hook

Core Purpose & Target User Orientation

This complete lineup of YG225 and YG160 series spare parts is precision manufactured exclusively for YG225 model travelling block assemblies, YG160 drilling hook units, and YG135B series supporting hoisting gear, covering all structural, sealing, transmission, locking and fastening components required for daily maintenance, fault repair and complete equipment overhaul. It caters to refined, scenario-specific user needs: oilfield on-site maintenance engineers, drilling equipment procurement teams, offshore platform operation departments, workover rig maintenance groups, and industrial drilling spare parts inventory managers who prioritize heavy-load stability, zero dust leakage, long component service life, precise fitting, safe locking performance and compliance with oilfield safety operation standards. The core purpose is to solve common on-site drilling hoisting pain points including hook locking failure, dust erosion damaging internal parts, oil seal leakage, pin shaft wear fracture, spring fatigue failure, and frequent unplanned rig shutdowns, providing a full-cycle, reliable spare parts solution for land deep-well drilling, offshore platform hoisting operations and desert oilfield construction.

Product Introduction

As a professional manufacturer focusing on oilfield hoisting equipment accessories, we supply full-specification YG225 and YG160 series spare parts, including travelling block covers, back plates, pulley shafts, oil seals, locking arms, hook bars, guide sleeves, pin shafts and matching fastening components. All parts are processed strictly in accordance with API 8A drilling equipment standards and national mechanical processing specifications, adopting high-strength alloy steel for load-bearing parts and wear-resistant, high-temperature elastomer materials for sealing parts, with dimensional tolerances controlled within 0.01mm to achieve 100% interchangeability with original equipment, requiring no on-site modification or secondary processing for installation.

Backed by 24 years of oilfield hoisting component R&D and manufacturing experience, we have a complete quality inspection system; every product undergoes load-bearing tensile testing, wear resistance testing and sealing performance testing before leaving the factory. Exclusive internal testing data shows that core load-bearing components such as YG225-03 pulley shaft and YG225-13 hook bar have a continuous safe service life of 2300 operating hours under rated heavy load, while YG225-06-00 anti-dust oil seals maintain complete sealing and dust-proof performance for 1800 consecutive hours without aging or damage. Each batch of products is equipped with factory quality inspection reports and material performance certification documents, fully meeting global oilfield safety operation and equipment acceptance requirements, making it a trusted choice for hoisting equipment maintenance.

Functional Description

1. Heavy-Load Hoisting & Force Transmission: Core components including pulley shafts, hook bars and hook load pins stably bear heavy drilling loads, transmit lifting force evenly without deformation or fracture, ensuring smooth operation of travelling block and hook assemblies.

2. Dust-Proof & Sealing Protection: Anti-dust oil seals and sealing sleeves block external dust, mud and impurities from invading internal components, preventing lubricating oil leakage and reducing abnormal wear of rotating parts.

3. Precise Positioning & Locking: Locking arms, crescent arms, guide keys and positioning fixing sleeves realize accurate positioning and reliable locking of moving parts, avoiding accidental displacement during hoisting and eliminating operational safety hazards.

4. Buffer & Reset Support: Matching springs and spring bases provide buffer shock absorption and automatic reset functions, reducing impact damage caused by frequent hoisting start-stop and prolonging overall equipment service life.

5. Stable Connection & Fixation: Full series of pin shafts, stop collars and clips fix and fasten each assembly, preventing part loosening caused by long-term equipment vibration and ensuring stable operation of the entire hoisting system.

Structural Features

YG225 and YG160 series parts adopt a modular integrated design, matching the original equipment structure perfectly for quick disassembly and installation. Load-bearing components adopt integral forging technology, with uniform internal stress and strong tensile resistance; sealing components adopt a double-layer labyrinth dust-proof structure, enhancing sealing and dust-proof effects. Pin shafts and locking arm pins adopt precision grinding technology, with smooth surfaces reducing wear; positioning fixing sleeves and guide keys adopt clearance fit design, ensuring precise positioning without jamming. All back plates and supporting plates adopt reinforced structure design, improving overall stability of the equipment and resisting deformation under heavy load.

Applicable Working Conditions

Suitable for land deep-well drilling, offshore platform hoisting operations, desert oilfield construction and shallow/deep well workover operations, adapting to an ambient temperature range of -28℃ to 125℃. It can operate stably under high-dust, high-humidity, corrosive marine environments and continuous heavy-load conditions, fully compatible with YG225 travelling block, YG160 hook and YG135B series hoisting gear, suitable for daily routine maintenance, damaged parts replacement and complete equipment overhaul.

Maintenance & On-Site Engineer Operation Suggestions

1. Routine Inspection: Check anti-dust oil seal integrity, pin shaft fastening status and locking arm flexibility every 180 operating hours; inspect spring fatigue degree and pulley shaft wear to arrange parts replacement in advance.

2. Lubrication Tips: Regularly replenish special high-temperature resistant lubricating grease for rotating and moving parts, avoid dry friction leading to bearing burnout and shaft wear; keep lubrication ports clear at all times.

3. Installation Avoidance Reminder: Keep mating surfaces clean and free of mud impurities during part replacement; tighten fasteners with rated torque, avoid excessive force causing thread sliding or pin shaft deformation.

4. Critical Maintenance Warning: Do not reuse deformed pin shafts, fatigued springs and damaged oil seals; replace matching components as a whole when repairing locking and sealing systems to avoid secondary failure and safety risks.
