This measuring device allows you to quickly check the diameter of the iron hammer head, its centre of gravity and the total length of the hammer measured from inside the handle, showing the result on a graduated scale according to the parameters of World Athletics (WA).
The post is made of 80mm square extruded aluminum profile. The mechanism is located on this post, made of steel, which measures the diameter and length of the hammer. The measuring mechanism is adjusted using a simple knob-operated system. It has graduated scales that indicate the diameter, length, and applicable tolerances according to the category to which the hammer belongs. To facilitate transport of the measuring device, the post has a handle on the top.
The base, which is made of steel to provide sufficient strength and weight to prevent the post from moving, has two 80 mm diameter wheels with a rubber thread to avoid marking the pavement. It has a calibrated piece to check that the centre of gravity of the hammer head is within the limits of the regulations. It also has two threaded knobs for levelling and a bubble indicator for positioning and levelling.
