ABSTRACT:
A concrete striking equipment presented in the form of a framework mounted on a longitudinal bar operating in a vibratory relationship in a horizontal plane because of an off-center rotating weight defining a part of the powering means. While basically developed for striking concrete, the invention's field of utility extends to the leveling and/or grading of earth and rock.
