Product Introduction
The kelly swivel of a rotary drilling rig is an important component that connects the kelly bar and the rotary drive. It is mainly used to lift, lower, and rotate the kelly bar, while transmitting torque and pressure during the drilling process.
Function of the swivel

1.Connection function: Connect the power head and drill rod to transmit torque and axial force.

2.Guidance function: Ensure that the drill rod remains vertically aligned during lifting or lowering, reducing deflection.

3.Protective function: Reduce wear between the kelly bar and the rotary drive, and extend equipment life.

4.Flexibility: Allow the kelly bar to have a certain degree of freedom during rotation and adapt to hole position deviations.

Applicable brands
1.Domestic: Sany, XCMG, Sunword, etc.

2.International: Bauer, Casagrande, Liebherr.
