An anti-skid structure is provided. The anti-skid structure includes a mounting plate having a surface, a first length and a second length, with a plurality of projections embossed on the surface of the mounting plate. Each of the plurality of projections includes a frustum structure, and a cylindrical structure on a top of the frustum structure. A distance between each projection of the plurality of projections, and an adjacent projection of the plurality of projections, along each of the first direction and the second direction is 44 mm. 1a mounting plate having a surface, a first length along a first direction and a second length along a second direction; anda plurality of projections embossed on the surface of the mounting plate, the plurality of projections comprising:a frustum structure; anda cylindrical structure on a top of the frustum structure, wherein a distance between each projection of the plurality of projections, and an adjacent projection of the plurality of projections, along each of the first direction and the second direction is 44 mm.. An anti-skid structure comprising: The present disclosure relates to an anti-skid structure, and more specifically, to an anti-skid structure having an optimal pitch distance.Heavy machines such as hydraulic excavators typically have walkway platforms to facilitate a user to reach different access points for daily maintenance activities. These walkway platforms are well above the ground level and, depending on the weather and the working environment, are exposed to dry, wet, or muddy conditions. The walkway platforms are desired to provide a non-slippery surface for better safety of the operators. Typically, the walkway platforms are provided with projections embossed on a metal plate.Currently, projections are formed by punching the metal plate, using turret machines with a specialized tool. The parts of the specialized tool are expensive, and need regular maintenance and/or complete replacement after certain ...
