A mining machine comprising:
- a base having a first end and a second, opposite end;
- drive tracks coupled to the base;
- a boom coupled to the base and extending from the first end of the base;
- a handle coupled to the boom;
- a dipper coupled to the handle;
- and
- a counterweight system coupled to the second end of the base, the counterweight system having:
- a body having a top wall, a bottom wall, a first side wall, a second side wall, and a plurality of internal walls disposed between the first side wall and the second side wall, each internal wall extending in a direction from the top wall to the bottom wall, wherein the internal walls and the first and second side walls define a plurality of internal sections;
- and
- a plurality of counterweight slabs, each counterweight slab sized to fit entirely within one of the internal sections by inserting the counterweight slab laterally along a direction toward the first end of the base.
