FAQ

1. What is a Kelly bar?

A Kelly bar is a key component of a chobowola rotary used in construction, essential for deep foundation drilling. It's a telescopic bar that transfers torque and downward force from the drill rig to the drilling tool.

2. How does a Kelly bar function?

The Kelly bar is attached to the rotary head of the drill rig. As the rotary head rotates, it turns the Kelly bar, which in turn rotates the drilling tool (like an auger or kubowola ndowa) attached to it.

3.What are the types of Kelly bars?

There are two main types: interlocking and friction. Interlocking Kelly bars have drive keys for higher torque transmission, while friction Kelly bars rely on friction between the sliding elements.

4. What is the role of a Kelly bar in drilling?

The Kelly bar is responsible for transmitting the rotational force and the downward pressure required for the drilling operation, making it possible to drill deep foundations.

5. How deep can a Kelly bar drill?

The drilling depth is determined by the length of the Kelly bar. Longer Kelly bars allow for drilling deeper holes.

6. Are Kelly bars universal for all drill rigs?

No, Kelly bars need to be compatible with the specific drill rig. Their selection depends on the rig’s specifications and the requirements of the drilling project.

7. What is the difference between interlocking and friction Kelly bars?

Interlocking bars are more efficient in transmitting torque due to their locking mechanism, making them suitable for harder ground conditions. Friction bars are simpler and used in less demanding conditions.

8. What determines the choice of a Kelly bar for a project?

The choice depends on the depth and diameter of the hole to be drilled, the ground conditions, and the capabilities of the kuyendetsa zala.

9. How is a Kelly bar maintained?

Regular inspection and maintenance are crucial, including checking for wear and tear, lubricating the telescopic sections, and ensuring the locking mechanisms are functioning properly.

10. Can a Kelly bar be used with different drilling tools?

Yes, a Kelly bar can be used with various drilling tools like augers, drilling buckets, and core barrels, depending on the specific requirements of the drilling operation.
