　　The professional ESCO bucket tooth pin supplier said we also can called the drag line excavator as the pull shovel excavator, because its excavate direction is the back and below direction, so we can use it to excavate the soils and materials, which is lower than stop machine surface. During the excavate period, drag line excavator will under the help of inertia force to throw out the ESCO bucket tooth pin with the far distance, so its excavate diameter and depth all very big. But compared with backhoe excavator, ESCO bucket tooth pin supplier said the backhoe excavator i more flexible and accuracy.

　　The other name for clam shell excavator is grab bucket excavator, because its excavate direction is straight up and down, which used to excavate soils below the stop machine surface too. The ESCO bucket tooth pin supplier said if the working area is softy soil areas, we can use the clam shell excavator to excavate the based pits and deeply open caisson.
