Series of Travelling Hook

The Series of Travelling Hook is a core heavy-load hoisting component of oilfield drilling and workover rigs, strictly designed and manufactured in accordance with API Spec 8C international petroleum industry standards. Covering full YG/DG series mainstream models ranging from YG50 to YG450, this integrated traveling block and hook assembly perfectly matches shallow, medium, deep and ultra-deep well rig configurations. As the key load-bearing and moving unit of the whole hoisting system, it cooperates with derrick, drawworks and fixed block to complete core operations such as tripping drill strings, running casing, lifting downhole tools and heavy-load hoisting. Adopting integral block-hook integrated structure design, high-strength alloy steel forging and welding forming, and intermediate-frequency quenched sheave grooves, the equipment features compact overall structure, high structural rigidity and excellent impact resistance. All primary load-bearing components undergo strict non-destructive testing (NDT) to eliminate internal structural defects. Equipped with reliable hook safety locking device, flexible 360° rotating mechanism and high-precision pulley assembly, it adapts to long-term high-intensity cyclic heavy-load operation. With full-climate environmental optimization design, the series travelling hook provides ultra-stable heavy-load hoisting guarantee for onshore oil and gas drilling, well completion, workover maintenance and large-scale cluster well construction projects.

Core advantages

Designed around the operating requirement.

Full-Series Model Coverage & Wide Rig Compatibility

The complete product series covers multiple load grades from 445kN to 4500kN, fully matching small workover rigs, medium conventional drilling rigs and heavy-duty ultra-deep well drilling rigs. Standardized overall dimensions, pulley parameters and installation interfaces realize seamless compatibility with mainstream domestic and international rig brands, meeting full-range operational demands from daily shallow well maintenance to ultra-deep well high-load drilling construction.

Integrated Heavy-Duty Structure & Ultra-High Load Capacity

Adopts optimized block-hook integrated integrated structure, effectively shortening suspension distance and maximizing hoisting travel space. Main load-bearing parts are made of high-strength alloy steel through integral forging and integral welding process, with uniform internal stress and strong structural toughness. Strict NDT quality control ensures no fatigue defects, enabling long-term stable bearing of rated heavy loads and resisting instantaneous impact load during tripping operations.

Wear-Resistant Pulley Assembly & Long Service Life

All sheave grooves adopt intermediate-frequency surface quenching treatment, forming high-hardness wear-resistant layer to effectively resist steel wire rope friction and impact abrasion. The precision pulley bearing assembly reduces rotational friction resistance, ensuring flexible and stable rope winding and unwinding. It avoids abnormal rope wear and pulley jamming, greatly extending the service life of both travelling hook and matching steel wire ropes.

Flexible Rotation & Reliable Safety Locking

The main hook body supports 360° free rotation with positioning locking function, adapting to multi-angle tool alignment and directional drilling operation demands. Equipped with high-sensitivity anti-drop safety latch and mechanical locking device, it effectively prevents accidental unhooking and tool falling risks during high-altitude heavy-load hoisting, comprehensively improving on-site operation safety.

Full-Climate Harsh Environment Adaptability

The whole machine adopts anti-corrosion, rust-proof and weather-resistant protective coating. Core structural components adopt wide-temperature anti-aging and fatigue-resistant configuration, supporting stable continuous operation within -40℃ ~ +55℃. It perfectly adapts to extreme working environments such as desert high temperature, Gobi wind-sand erosion, muddy well sites and high-altitude low-pressure cold plateaus.

Modular Design & Low Maintenance Cost

Adopts standardized modular assembly layout with highly universal wearing parts and accessories. The reasonable internal structural layout simplifies daily inspection, lubrication maintenance and pulley replacement. The low-failure structural design reduces unexpected downtime, effectively lowering long-term operation and maintenance costs of oilfield hoisting systems.

Buyer questions

Frequently asked about this equipment.

The following questions address common equipment selection and operating considerations.

What is the core function of Travelling Hook in oilfield rigs?

The travelling hook is the core heavy-load hoisting component of drilling and workover rigs. It cooperates with the whole hoisting system to bear downhole string weight and complete all heavy-load hoisting operations such as drill string tripping, casing running and downhole tool lifting, which directly determines the safety and efficiency of wellbore construction.

What are the advantages of integrated block-hook structure?

Compared with split structures, the integrated travelling hook features compact overall layout, smaller suspension height and larger effective hoisting travel. It has higher overall structural rigidity, stronger impact resistance and more stable load-bearing performance, effectively avoiding connection looseness and structural deformation during long-term heavy-load operation.

How to select the correct travelling hook model?

Model selection is based on rig load tonnage, designed maximum well depth and construction load demand. Small-tonnage models such as YG50/YG90 suit shallow well workover; medium models YG110/YG135 match medium-depth well drilling; heavy-duty YG225/YG315/YG450 adapt to deep and ultra-deep well high-load drilling projects.

How to ensure long-term wear resistance and stability?

The sheave grooves adopt professional intermediate-frequency quenching treatment for high hardness and wear resistance. The high-precision bearing assembly ensures flexible rotation and uniform stress. All load-bearing parts pass strict NDT inspection, with excellent fatigue resistance and structural stability, adapting to long-term cyclic heavy-load operation.

Can structural parameters and configurations be customized?

Yes. We support personalized customization of load grade, sheave specification, hook opening size, safety locking structure and environmental protection configuration, matching different rig models, wellbore construction conditions and regional operation safety standards.
