300 to 2700 kN Hook Load
Rated load steps 300, 585, 675, 784, 900, 1125, 1350, 1580, 1800, 2250 and 2700 kN across the YG30 to YG270, matching a shallow workover block to a deep-drilling hook-load envelope.

Series of Travelling Hook
The YG travelling-block-and-hook series runs from the YG30 at 300 kN rated load to the YG270 at 2700 kN, with pulley sets of three to five sheaves strung on 22, 26, 29 or 32 mm wireline depending on model. All twelve variants carry a three-hook body, and unit mass grows from 490 kg on the YG30 to 4900 kg on the YG270. The combined block-and-hook is the point where drill-line pull becomes hook load, carrying the string into the derrick and presenting the elevators and tool joint to the driller.
Core advantages
Designed around the operating requirement.
Three to Five Sheaves
Sheave count runs three on the lighter YG30 and YG70 to five on the YG160, YG225 and YG270, the line configuration that trades drum pull against hook speed at the chosen number of lines.
22 to 32 mm Wireline Match
Applicable drill-line diameter is 22 mm on the YG60 and YG70, 26 mm through the mid-range, and 29 to 32 mm on the YG180, YG225 and YG270, so the block is ordered to the rig wireline rather than re-bushed.
Three-Hook Body on Every Model
All YG variants use a three-hook body, giving a common elevator and latch arrangement across the range so crews trained on one model work the whole fleet without a new latch-up routine.
490 to 4900 kg Assembly Weight
Block-and-hook mass runs 490 kg on the YG30 to 4900 kg on the YG270, the lift weight the derrick handling and floor crew plan for when the block is rigged in or moved.
Drill-Line to Hook Load Conversion
The block converts fast-line pull into multiplied hook load through the sheave count, and the YG series is sized so that at the rated number of lines the drill line stays inside its own tension limit at maximum hook load.

Buyer questions
Frequently asked about this equipment.
What buyers check on the travelling hook series: hook rating, line arrangement and rig-class fit.
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?
The integrated block-and-hook is shorter in suspension height than a split block and hook, which frees headroom on the derrick and gives more effective hoisting travel. The one-piece body also removes the bolted connection point that is the typical failure mode on long-cycle heavy loads — no separate block-to-hook joint to work loose.
How to select the correct travelling hook model?
Model selection is set by the rig's maximum hook load and the drill line already on the drawworks, not by a generic tonnage class. The light group — YG30 at 300 kN through YG90 at 900 kN — matches shallow workover and 250 HP class rigs. The mid group — YG110 at 1125 kN through YG160/160B at 1580 kN — covers medium-deep drilling and the 350/450 HP workover class. The heavy group — YG180 at 1800 kN through YG270 at 2700 kN — is for deep drilling and the 750 HP and larger rigs. Send the rig hook rating, the drill-line diameter and the planned reeving count and we quote the exact model from the twelve in the range.
How to ensure long-term wear resistance and stability?
The sheave grooves are induction-hardened for wear resistance against the drill line, and the bearings are precision-assembled for even load distribution. Load-bearing parts are NDT-checked before dispatch, and the three-hook latch is cycled on the shop test rig. The block is sized to the rig's drill line and hook rating rather than to a generic tonnage class.
Can structural parameters and configurations be customized?
Yes. The configuration is settled against the drill line and derrick before the order: rated load (YG30 at 300 kN to YG270 at 2700 kN), sheave count, applicable wireline diameter (22 to 32 mm) and the three-hook latch and elevator interface are matched to the rig reeving, then written into the quotation and the factory test report.
