The Vibroflot operates on the principle of vibration compaction. Its high-power vibrator generates high-frequency vibrations, which are transmitted to soil particles. Under the influence of these vibrations, loose soil particles rearrange themselves, reducing voids and significantly enhancing soil density and bearing capacity. Additionally, the built-in water flushing system assists in loosening the soil during operation, enabling the vibrator to penetrate deeper into the soil layers and further optimizing treatment results. Whether dealing with sandy soil, silty soil, or other liquefiable soils, the Vibroflot efficiently reinforces the soil, effectively preventing foundation settlement and providing a solid and stable base for superstructures.

Understanding Kelly Bar Types in Rotary Drilling Rigs

August 7, 2025

1. What Is a Kelly Bar?

A Kelly bar is a key component of a rotary drilling rig, used to transmit torque and crowd force from the rig’s rotary drive to the drilling tool. It enables the rig to reach deep drilling depths while maintaining high torque.

2. Types of Kelly Bars

? Interlocking Kelly Bar

Provides high torque transmission
Ideal for hard soil and rock layers
Better vertical rigidity and depth control

? Friction Kelly Bar

Lighter and more economical
Suitable for soft to medium soil
Faster drilling speed

3. Common Specifications

Type	Sections	Max Drilling Depth	Torque Capacity
Interlocking	3–6	Up to 90 m	High
Friction	3–5	Up to 60 m	Medium

4. Application Scenarios

High-rise building foundations
Bridge pile foundations
Infrastructure and civil engineering projects

5. Maintenance Tips

Lubricate locking mechanisms regularly
Avoid over-torqueing in rocky ground
Inspect for wear at section joints
