Engineer Available To Serve Overseas For Zoomlion Rig Square Soilmec Type Excavator Crane Spare Parts Sr-40 Locking Kelly Bar

Unicorn Drill Drilling Kelly Bar adopt the high-carbon steel (Q345B, 16Mn, Q195-Q345, etc.) and special welding method to keep the drilling strength and efficiency.

Purchase the standard drilling kelly bars.

1) Friction Kelly Bar

    Friction kelly bar needn't unlock the joint of its inner and outer lining, so that it is convenient and fast to lift the bar. Non-stair key, friction transmission the out side key is made by highly wear-resistion tempering teel. for layer of soft ground and mud sand gravel.

    Features:For a torque range of 10-350kN.m.

                      In length u to 110m.

                   High quality raw materials with superior strength from the leading manufacturers.

                      Experienced technicians and operators to assure the best quality.

                   Engineers are available to service machinery overseas.

2) Interlocking Kelly Bar

      Interlocking kelly bar is of great pressure transmission and good anti-contortion perfomance. There are 3 rigid parts between drilling pipes to transfer greater pressure from embedding cylinder. And even at the hard geologic condition it can transfer greater pressure and drill in. Stair key, organization transmission, the outside key is made by highly wear-resisting tempering steel. For soft fromations, (weak) weathered rock, hard strata construction. 

   Features:For a torque range of 10-350kN.m.

                      In length u to 110m.

                   High quality raw materials with superior strength from the leading manufacturers.

                     Experienced technicians and operators to assure the best quality.

                     Engineers are available to service machinery overseas.
