PILE CROPPING APPARATUS

摘要

A pile-cropping apparatus comprises a lifting body (1) of generally rectangular form with an internal longitudinal through passage (2) open at the top and bottom of the lifting body for receiving the top of a pile, and a top plate adapted for lifting (3) the body with lifting eyes (4) arranged around the periphery of the top plate. Opposed bucket shells (5, 6) are positioned about the lifting body and have lobes (17, 18) attached to respective pivot pins (15, 16) which are fixed to the lifting body such that the upper edges (27, 28) and lower edges (37, 38) of the respective shells are movable towards and away from a cutting zone below the lower end of the lifting body. Overhead transverse paired linear actuators (40, 41) act reversibly upon the upper edges of the shells. Opposed cutter or breaker elements providing bevelled hardened edges (30, 31) upon the lower edges of the respective shells enable concrete breaking and rebar cutting.
