2. Brief Introduction

Clam shell buckets are used for soft silt and clay formation of strong adhesiveness. The shell and the kelly box of clam shell bucket is connected by two hinges.  The shell body can be opened and closed by its self-rotation. It is applied to bore small diameter holes for clay formation. The unique design helps to dump the earth out from the shell body. There is no pilot for clam shell bucket and the teeth is distributed in a interlocked order. These years, bullet teeth are widely used on clam shell buckets for different layers.
