The invention aims at providing construction equipment for automatically controlling tamping of a heavy hammer. The construction equipment comprises a chassis, wherein a bracket is arranged at the front end of the chassis, a pulley is arranged at the upper end of the bracket, the chassis is provided with a winch, a rope extends out from the winch and is connected with the heavy hammer, and the heavy hammer can penetrate into a protective cylinder. The construction equipment is characterized in that the winch is provided with a computer automatic system used for controlling a drum system and a brake system of the winch, after the lifting height of the heavy hammer is set on an operation panel of the automatic system, manual operation is not needed, and the winch automatically lifts the heavy hammer to a set height and then enables the heavy hammer to freely falls, so that the heavy hammer carries out the tamping according to the set height, the processes are repeatedly carried out, and the lifting height of the heavy hammer can be regulated at any time; the winch is also provided with an external controller used for controlling the brake system of the winch, and the lifting and falling actions of the heavy hammer are controlled at any time by virtue of a stop key and a start key of the external controller.
