What are the top problems kelly bar drilling bucket tools might meet

To foundation engineering companies, we all know that the kelly bar are usually used with drilling bucket tools together. The drilling buckets are used to do the bore piling work, Drilling bucket tools are most vulnerable to damage because they directly do the rock layer cutting job. So, do you know what are the top problems kelly bar drilling bucket tools might meet, following we would like to give you a detail introduction. 

Drilling buckets tools, as the arms in bored piles piling constructions, are most commonly used. This also mean drilling bucket tools generate the most problems for foundation engineers and rig operators. We have analyzed and summarized best practice solutions to common problems you might encounter when you operate rotary rig drilling buckets!

1. Bucket wall worn out, causing the bottom plate to fall.

The bottom of the bore piles drilling bucket withstands lots of stress, only second to the drilling teeth! As drilling goes, the lower wall of the drilling bucket can get worn and becomes very thin, which may cause the bottom plate to fall off! This requires us to regularly check and change the wear-resistant stripes in time, to ensure the wall is not overloaded with stress.

2. The bottom plate deforming.

When the bored piles drilling bucket is full, because the bottom plate is connected by the pin and the shaft, it can get stuck at times, causing difficulty to lift the drilling tool out. When this happens, the best thing to do is to slightly adjust the positioning of the drilling tool so it gets unstuck by itself. Forceful pulling the drilling tool is usually the primary reason for the bottom plate to fall. Avoid the impulse and don’t do that!

3.The unlocking mechanism being stuck.

If you drill in really sticky soil, this can happen quite often. When he unlocking mechanism will need extra strength to open up. If you force it too much, the unlocking system of the drilling tool will be deformed and stuck. To prevent this, wash your locking systems in time and regularly!

Operating the drilling bucket tools are never easy and requires and long learning curve. For professional expertise and good quality service, you could always rely on us!
