Belling Bucket

When conditions of soil are stable (mainly cohesive), belling buckets are used for enlarging the pile base. By use of the leverage system and application of vertical crowd force on the push rod, the cutting arms are gradually opened. The drilled material falls into the open shell of the bucket. The cutting arms are closed by upward movement of the kelly bar which transmits the pull onto the push rod.

We could offer different types of belling buckets, coring barrel and clam drilling bucket which can be manufactured for any diameter as per customer's request:
