Drilling Rig Parts Forging IMT Kelly Bar for IMT Piling Rig in Deep Foundation
Methods used to avoid or reduce slipping phenomenon
| A | Before each drilling, rotate the rotary drive clockwise to open the feed port of drilling tool |
| B | When drilling into the earth, the bucket should not be fully filled. 70% or 80% is great |
| C | Weld spring steel pate on the worn tooth to extend it |
| D | Change drilling tool, such as spiral drill tool |
These methods should be used accroding to actual situations.
Appropriate method can be used to improve drilling efficiency.

What is kelly bar?
Kelly bars are key components in the execution of boreholes by hydraulic rotary drilling rigs. Telescopic Kelly bars transfer torque and crowd force from the rotary drive to the drilling tool.
Kelly bars can be selected into friction and interlocking type. Friction kelly bars are properly defined by their frictional contact between rail of each element. Interloking kelly bars are indeed privided with drive ribs which are welded with lock devices in order to transfer the maximum torque to each scope.
IMT Kelly Bars are made of special type steel with strengths graded at 1000 MPa. Canister thickness. IMT uses a thickness of 12.5 mm for the outer element, instead of 10 mm, therefore making it more resilient in time.

1. Why choose us ?
Construction and welding manufacturing process of Kellyway kelly bars is by means of high quality materials and high mechanical features steel, provided with origin and quality certificates to guarantee long-life and reliability of the product after accurate engineering process.
In short, here are some of the advantages that the IMT Multi-Lock Kelly Bars offer, as opposed to the standard J-lock Kelly bars:
The rotary on the kelly bar can be locked at any point, undoubtly resulting in better flexibility.
It completely eliminates the “friction drilling”. As have been noted, friction drilling is the time that the rotary is sliding down the kelly bar canister without being locked. Therefore, production is increased.
Ability to transfer the entire constant crowd force to the drilling tool, hence maximizing efficiency.
Obviously, multiple locks will significantly improve the life of the whole kelly bar. As a result, the even distribution of forces and momentum ensure the IMT kelly bar durability and reliability.
Steel strength. IMT Kelly Bars are made of special type steel with strengths graded at 1000 MPa.
Canister thickness. IMT uses a thickness of 12.5 mm for the outer element, instead of 10 mm, therefore making it more resilient in time.
Canister length. IMT manufactures their kelly bars using three tiles of 1 metre each, for the purpose of strengthening and increasing the durability of the tube.
