A counterweight assembly, for a lifting machine, comprising:
- a plurality of counterweight slabs, including:
- first and second outer counterweight slabs;
- and
- one or more inner counterweight slabs sandwiched between inner lateral surfaces of the first and second outer counterweight slabs,
- wherein an outer lateral surface of each outer counterweight slab includes one or more recesses having one or more respective reflective decals disposed therein.
A counterweight slab, for a lifting machine, having a body comprising:
- a first lateral surface;
- a second lateral surface facing away from the first lateral surface;
- and
- a side surface extending around a perimeter of the body,
- wherein the side surface connects together the first lateral surface and the second lateral surface, and
- wherein the first lateral surface includes one or more recesses having one or more respective reflective decals disposed therein.
A method of manufacturing a counterweight slab, for a lifting machine, comprising:
- cutting, with a plasma torch, a profile of the counterweight slab from a larger steel slab,
- wherein the profile corresponds to a shape of a lateral surface of the counterweight slab;
- machining, with a machine tool, one or more recesses into the lateral surface of the counterweight slab;
- and
- applying one or more respective reflective decals to the one or more recesses.
