At the upper part of the blade along the axis the tubular holder of a shank is made. On the left and right of the holder, in the direction of the front part of the blade, the left and the right lapels for putting a foot are made. The shovel is equipped with a removable-disassembled grate supporting lever. The support lever is placed on the opposite side from the front part of the shovel blade and has a thrust button.

Each base is rigidly attached to the longitudinal rods, which second ends are rigidly attached to each other by their transverse bars, the left and right, which at the inner side of each part have their own ledge. On one ledge a tube is installed to half its length, and is rigidly fixed. The ledge of the second part is loosely inserted into the hole of the tube and is fixed with a forelock in a transverse hole. Near the upper ends of the longitudinal rods to each part the second transverse plate is attached, having a ledge from the inner side of each part. On one ledge a second tube is installed to half its length, and is rigidly fixed. The ledge of the second plate of the second part is loosely inserted into the hole of the second tube and is fixed there with the second forelock in the transverse second hole for fixing both parts from automatic doffing.
