Also known as a "spin breaker", it eliminates the rotational force generated by the wire rope during lifting and lowering, preventing the wire rope from twisting. It is a very important key component used in rotary drilling rigs and diaphragm wall grabs for lifting and suspending drill pipes, drilling tools, and diaphragm wall grabs.
Based on the construction conditions of rotary drilling rigs and diaphragm wall grabs, our company has carefully designed and manufactured the Kelly swivel, which has the following characteristics of high cost-effectiveness, high efficiency, and high reliability:
The upper and lower connectors, intermediate body, etc. of the Kelly swivel are all made of high-quality alloy steel, finely machined and strictly heat-treated, giving it excellent comprehensive mechanical properties, strong wear resistance, and long service life.
All internal bearings use SKF bearings, offering excellent performance and extremely long life.
All sealing elements are imported parts, resistant to corrosion and aging, ensuring that the grease in the bearing cavity does not leak easily and that external mud and debris do not easily enter the bearing cavity, thereby ensuring normal operation of the bearings.
The lubricating grease can be replaced periodically; the grease will not deteriorate due to temperature rise during long-term use, thereby extending the service life of the Kelly swivel.
