Abstract
A pile remover has a first embodiment for removal of short pilings and a second embodiment for long pilings. Both embodiments include a pile-fitting tube with hydraulic cylinders at the top end of the tube that push downward to cause rocking cutters at the bottom end of the tube to pivot with sharpened ends moving inward to shear off the piling. Both embodiments are designed for use with a back hoe or a derrick. After a piling has been shearing, with the cutters still in cut position, the back hoe operator can lift the cut off piling and deposit it on a barge or other conveyance by reversing the cutter action and drooping the piling.
