Rig Drill Tool Interlocking Kelly Bar Friction Deep Foundation Piling

1. Strict selection of raw materials from large fctories and forging parts such as drive stub to assure the reliable quality;
2. The key parts such as drive keys are used by heat treatment to improve wear resistance ;
3. With high torsional coefficient ,the compression and vibration resistance of Kelly bar is higher than average level.

4.Interlocking Kelly Bar is an important part of hydraulic rotary drilling rig, which directly affects the transmission pressure and working efficiency. Our Kelly bar uses advanced processing equipment and experienced engineers more than 8years, and complete strict quality control system.
5.Interlocking pressure Kelly bar contains 3 or 6 foreign keys with 3 or more sets of recessed pressure parts. Easy to transmit pressure and better resistance to torque. It is suitable for both dense sand and gravel as well as highly weathered to bedrock.
