Summary:PURPOSE: A removing method and equipment of a concrete column are provided to crush the concrete column by pressure for penetrating and digging the outer periphery of the column at the constant depth by operating piston rods of hydraulic cylinders mounted at a crush mechanism at the same time. CONSTITUTION: A removing method of a concrete column is composed of steps for forming a crusher mechanism(1) by connecting plural cylinder blocks(3) fixed and mounted with at least one hydraulic cylinder(2) to surround the concrete column to be removed; positioning the crush mechanism to encircle the outer periphery of a crush portion of the column by using a crane or a lifting structure; and operating piston rods(21) of each hydraulic cylinder by supplying hydraulic pressure to the hydraulic cylinders arranged in the crush mechanism and crushing the column by perforating through the column by the front ends of the piston rods at the constant depth. The column is removed by repeatedly cutting or crushing a part surrounded by the crush mechanism.
