Claim 10:
11. A mobile silo-filling system, comprising:
a base configured to be positioned on a ground, wherein the base comprises:
a truck unloader having a plurality of wheels; and
a first conveyor configured to convey a proppant, wherein the first conveyor comprises a trough-style unloading conveyor;

a derrick having a first end that is coupled to the base, wherein the derrick is configured to be oriented substantially horizontally when the system is in a folded state, wherein the system is configured to be coupled to a vehicle and to be moved by the vehicle when in the folded state, wherein the derrick is configured to be oriented at an angle from about 20 degrees to about 70 degrees when the system is in a partially unfolded state, wherein the derrick is configured to be oriented substantially vertically when the system is in an unfolded state, wherein the derrick comprises a second conveyor configured to receive the proppant from the first conveyor and to convey the proppant when the system is in the partially unfolded state, the unfolded state, or both, and wherein the second conveyor comprises a bucket elevator;
one or more hydraulic cylinders coupled to the base and the derrick, wherein the one or more hydraulic cylinders are configured to actuate the system between the folded state, the partially unfolded state, and the unfolded state;
a first arm having a first end that is coupled to a second end of the derrick, wherein the first arm is configured to be substantially horizontal when the system is in the folded state, the partially unfolded state, and the unfolded state, wherein the first arm is configured to rotate around the first end thereof in a first horizontal plane, wherein the first arm comprises a third conveyor configured to receive the proppant from the second conveyor and to convey the proppant, and wherein the third conveyor comprises a trough-style distributing conveyor;
a first slewing gear configured to transfer the proppant from the second conveyor to the third conveyor;
a second arm having a first end that is coupled to a second end of the first arm, wherein the second arm is positioned below the first arm, wherein the second arm is configured to be substantially horizontal when the system is in the folded state, the partially unfolded state, and the unfolded state, wherein the second arm is configured to rotate around the first end thereof in a second horizontal plane, wherein the second arm comprises a fourth conveyor configured to receive the proppant from the third conveyor and to convey the proppant, and wherein the fourth conveyor comprises a trough-style distributing conveyor;
a second slewing gear configured to transfer the proppant from the third conveyor to the fourth conveyor; and
a loading spout coupled to the second arm proximate to a second end of the second arm, wherein the loading spout is configured to telescope vertically, and wherein the loading spout is configured to receive the proppant from the fourth conveyor and to load the proppant into an inlet in an upper portion of a silo.
