Chain Link Types in Rotary Drilling Rig Undercarriage Systems
In the undercarriage system of drilling rigs, the crawler chain plays a vital role in transferring power and supporting the machine’s movement under heavy loads. Understanding the types of chain links used in different applications helps ensure optimal performance and longer service life.
There are two main categories of link assy (chain assemblies) used in foundation drilling equipment:
1. Sealed and Lubricated Crawler Chain
This type of chain link features built-in lubrication between the pin and bushing, protected by rubber seals. It significantly reduces friction and wear, providing longer lifespan and better reliability. Sealed link assy is widely used in rotary drilling rigs, crawler cranes, and other heavy-duty machinery working in tough jobsite conditions.
2. Dry Chain Link (Non-sealed Type)
Dry chains have no internal grease or sealing. These crawler chain types are more economical and easier to maintain but have a shorter service life due to higher wear. They are usually found in light-duty equipment or in temporary project use.
Yantai Orient supplies a full range of crawler chain assemblies, track shoes, bottom rollers, carrier rollers, idlers, and sprockets for rotary drilling rigs. Our products are compatible with major brands such as Bauer, MAIT, Soilmec,IMT and Sennebogen.

1. Tensioning cylinder failure. Check if there is no lubricating oil in the tensioning cylinder and if there is any oil leakage. 2. The track is severely worn. Long term use can also cause the wear of chain ribs and chain barrels on the track to cause the track to detach. 3. The chain protector is worn. Chain protectors play a very important role in preventing chain detachment, so it is important to check whether the chain protectors are worn.
1. High work efficiency: With the function of integrating drilling and grouting, the work efficiency is high, which can greatly shorten the construction cycle. 2. High safety: simple and convenient operation, which can avoid safety accidents caused by operational errors.
