Claims38
A mining machine comprising:
- a boom having an interior chamber;
- a handle slidably coupled to the boom;
- and
- a reel system disposed at least partially within the chamber;
- wherein the reel system includes a reel and at least one flexible conduit coupled to the reel;
- wherein the mining machine includes a dipper coupled to the handle, wherein the at least one flexible conduit extends from the reel system to at least one of the dipper, the handle, or a tilt actuator;
- and
- wherein the mining machine includes a base, and a first manifold disposed inside the boom, and wherein at least one rigid conduit extends from the base to the first manifold.
