Features and operation

A common shovel can have a height with its handle of 1.0 m, mass of 2.0 to 3.0 kg, with a working width of 250 to 300 mm, with the length of the shovel itself 250 mm, and 2mm thick, SAE 1075 steel , although variations in technical characteristics are many, according to the manufacturer.

The worker buries the blade of the shovel in the ground (or other material), for which he can help himself by pressing with his foot on the shoulder of the implement, or simply by pushing with his hands. It tilts the handle, thereby releasing the material, holding a part in the cavity of the blade, lifting and transferring it, and then pouring it in the place you want.
