1. Core Product Overview & Target Application

This complete range of spare parts is specially designed and manufactured for YG170 type oilfield drilling hooks, covering all core structural, transmission, locking, buffering and fastening components required for daily maintenance, fault repair and overall assembly of the drilling hook. Our target user groups cover on-site oilfield drilling mechanics, rig maintenance management teams, oilfield equipment spare parts procurement personnel, and drilling equipment after-sales service engineers, who are deeply troubled by mismatched spare parts, short service life of vulnerable parts, loose locking mechanisms under heavy load, and difficult on-site troubleshooting of drilling hook failures.

Core Purpose: All YG170 series parts are precision OEM direct replacement parts, built to maintain stable load-bearing performance, reliable safety locking, smooth transmission operation and effective buffer damping of YG170 drilling hooks. The parts fully comply with API 8C and national petroleum machinery manufacturing standards, providing a unified and standardized procurement reference standard for users, as well as a professional technical solution reference for on-site fault maintenance, fundamentally solving the common problems of unstable operation and safety hazards of drilling hooks in harsh oilfield environments.

1.1 Product Introduction

This product line includes all key components of YG170 drilling hook, with YG170-36 Shield pin, YG170-30 Swivel, YG170-26 Large hook body as core parts, supplemented by hook rod pins, lock tongue assemblies, buffer assemblies, side plate assemblies, pulleys, rollers, various safety pins, nuts, springs and fastening screws. Each part is made of special alloy steel for petroleum machinery, through precision forging, heat treatment and tolerance processing, with uniform material and stable performance. Exclusive factory testing data shows that the YG170-26 Large hook body can withstand 220 tons of static load for a long time without deformation; YG170-34 buffer assembly maintains stable damping effect for 1450 continuous operating hours; YG170-28 turn lock assembly achieves 9200 times of effective locking without failure, far exceeding the service life of ordinary aftermarket parts.

Backed by years of professional petroleum machinery manufacturing experience and complete quality inspection system, each part has passed dimensional inspection, load test and fatigue test before leaving the factory, with complete quality certification and performance reports, ensuring 100% matching with YG170 drilling hook installation size, no on-site modification or secondary processing required.

1.2 Function Description

Every YG170 series part undertakes an irreplaceable role in drilling hook operation: YG170-26 Large hook body bears the main lifting load of drilling tools, ensuring safe lifting operation; YG170-30 Swivel realizes flexible rotation of the lifting system, avoiding rope twisting; YG170-28 turn lock assembly and lock tongue realize reliable locking, preventing accidental unhooking; YG170-34 buffer assembly absorbs vibration and impact during lifting, protecting equipment and drilling tools; various safety pins and positioning pins form a dual safety protection mechanism, preventing parts from loosening under vibration; pulleys and roller assemblies realize smooth rope transmission, reducing friction loss; cylinder and piston rod assemblies assist in completing the opening and closing of the locking mechanism; flange, cover plate and sealing parts block mud and dust intrusion, protecting internal parts.

1.3 Structural Features

High-load bearing parts adopt integral die forging process, with refined internal grain and improved tensile and fatigue resistance; the surface of load-bearing parts is treated with anti-corrosion and wear-resistant process, adapting to harsh oilfield environments. Locking and fastening parts adopt precision machining, with perfect fit of matching surfaces, avoiding loosening caused by long-term vibration; spring parts use high-elasticity alloy steel, maintaining stable elasticity after repeated compression, not easy to break or deform. Pulley and roller shafts adopt high-precision grinding process, with small surface roughness and reduced wear of matching parts; buffer components adopt dual spring damping structure, with more stable buffering effect and stronger impact resistance. Stress concentration points of all structural parts are optimized with rounded design, effectively extending the service life of parts.

2. Applicable Operating Conditions

These parts are suitable for various oilfield drilling operation scenarios, including land desert oilfields, cold region oilfields, and shallow offshore drilling platforms, adapting to ambient temperatures ranging from -40℃ to 160℃. They can operate stably under heavy load, continuous vibration, mud erosion, dust and rain erosion conditions, fully meeting the requirements of YG170 drilling hook for daily drilling, workover and lifting operations. Whether it is conventional well drilling or heavy-load lifting construction, the parts can maintain stable performance and meet the safety standards of oilfield on-site operations.

3. Maintenance & Engineer On-Site Suggestions

3.1 Routine Maintenance Tips

Check the tightness of YG170-16/25 safety pins and various bolts every 100 operating hours, and replace deformed or worn pins immediately; inspect the wear of YG170-04 pulley and roller assembly every 30 days, and add special lithium-based grease for petroleum machinery on time. Check the elasticity of buffer springs and lock springs every 6 months, and replace springs with reduced elasticity in advance; clean the mud and debris inside the lock body and buffer assembly every quarter to prevent jamming. Check the locking effect of YG170-28 turn lock assembly before each shift, and troubleshoot unsmooth locking in time.

3.2 On-Site Maintenance Avoidance Tips

Strictly match part numbers during replacement, do not replace slotted nuts, round nuts of different specifications at will, to avoid loose fastening; do not reuse removed lock pins, positioning pins and other vulnerable fasteners; when disassembling and assembling the buffer assembly, do not change the pre-tightening state of the spring at will, so as not to affect the buffering effect. When replacing the large hook body and beam parts, ensure the installation plane is flat, and do not force installation with debris; use special tools to disassemble and assemble the lock assembly to avoid damaging the lock tongue and lock body.
