The kelly is the key component of the drilling machine, and its
quality directly affects the performance of the whole machine.
Based on rich manufacturing experience and absorbing advanced
technology at home and abroad, it produces two types of kelly,
interlocking and friction. The length of the kelly depends on the
actual needs of the customer or the parameters of the drilling rig
1. Adopt international advanced six-key power distribution
technology and standard modular design.
2. The whole set of kelly is light in weight, high in strength,
high in single-section straightness, thin in pipe wall, small in
joints between joints, and good in wear resistance of internal and
external keys, which greatly meets the special requirements of
rotary drilling rigs.
3. The material specifications are complete, and the kelly can be
matched with any rotary excavator at home and abroad. All our
kellys are full torque and have a maximum digging depth of 100
meters.
