Productin Description
Kelly Bar Description
Kelly bars are key components in the
execution of boreholes by hydraulic rotary drilling rigs. Teleskopic Kelly bars
transfer torque and crowd force from the rotary drive to the drilling tool.
Hunan HM Machinery Co is a highly specialized manufacturer of telescopic kelly
bars to be applied to any type of piling rig available in the market such as
Bauer, Sany, Xcmg, Zoomlion, Sunward, Soilmec, IMT, Mait.... Kelly bars are
featuring specific construction details:
• 2 - 5 fold telescopic construction for a depth range from 15 - 150 m
• the tubular kelly sections are manufactured from high-tensile steel to ensure minimum weight at adequate strength
• torque transfer capacity 120 - 480 kNm
• interlocking kelly bar type
• friction kelly bar type
• locks and wear-resistant drive rails (accordingly with rotary sleeve)
• Robust Terminal joints, that are the terminal part of each telescopic pipe, provided to transfer torque and crowd force to the kelly bar
• bottom shock absorbers
• standardised square kelly drive stub for connecting all types of drilling tools
HM Machinery Co kelly bars are designed by technicians and engineers with over 9 years experience. Construction and welding manufacturing process of 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.

Interlocking Kelly
Bar
Interlocking kelly bar system are
especially designed for drilling into hard materials and when crowd force
application is required.Locking kelly bars are provided with drive rails
designed with locking pockets on their length and corresponding termina joints
locking guides. The purpose is to interlock each telescopic element to the
inner following one in order to apply the maximum torque and crowd force
developed by the base rig.Therefore the rotary table inner drive is also
equipped with locking pockets,. When extracting the locking bar from down the
hole, the combination of lifting and rotating counterclockwise will allow the
telescopic element to unlock. interlocking Kelly bars are usually supplied with
3 or 4 telescopic elements.
Friction Kelly Bar
Friction kelly bar derives its name from
the means by which it transfer torque to the drilling tool. The telescopic
elements are advanced by using the “frictional contact” from each of the
friction drive rails that run down the outside of each kelly bar. These drive
rails, on the outside of each kelly bar, are driven by the rotary table and the
terminal joints of each successively larger diameter kelly bar. The terminal
joint is long piece on the inside and at the bottom of each kelly bar. Friction
kelly bars are normally supplied in 4 or 5 telescopic elements as they are
mostly used for deep piles in medium hard soil conditions.
