2 . The shiploader system of claim 1 , wherein said coupler pivotally couples the truck unloader to said radial stacking conveyor.
3 . The shiploader system of claim 1 , wherein said coupler comprises an upper pivot, said upper pivot being coaxial with a tail pivot of said radial stacking conveyor.
4 . The shiploader of claim 1 , wherein said truck unloader is coupled to said radial stacking conveyor by a strut, said strut being configured to raise said truck unloader into said transport configuration.
5 . The shiploader of claim 1 , wherein said truck unloader is coupled to said radial stacking conveyor by an extendable strut.
6 . The shiploader system of claim 1 , wherein said truck unloader is in end-to-end relation to said radial stacking conveyor in both the transport configuration and the operational configuration.
7 . The shiploader system of claim 1 , wherein said truck unloader is in end-to-end relation to said radial stacking conveyor in both the transport configuration and the operational configuration.
8 . The shiploader system of claim 1 , wherein a truck unloader is in side-by-side relation to said radial stacking conveyor.
9 . The shiploader system of claim 1 , wherein said truck unloader is in side-to-side relation to said radial stacking conveyor in both the transport configuration and the operational configuration.
10 . The shiploader system of claim 1 , wherein said radial stacking conveyor comprises a forward wheel assembly and a rear wheel assembly.
11 . The shiploader system of claim 10 , wherein said forward wheel assembly and said rear wheel assembly cooperatively enable said radial stacking conveyor to move in a transverse direction.
12 . The shiploader system of claim 10 , wherein said forward wheel assembly and said rear wheel assembly cooperatively enable said radial stacking conveyor to rotate around a point disposed between said forward wheel assembly and said rear wheel assembly.
13 . A shiploader control system for a shiploader system having a transport configuration and an operational configuration, the shiploader system having a radial stacking conveyor with a first head-end drive pulley, the shiploader system having a truck unloader with a second head-end drive pulley and an unloading zone conveyor section, the unloading zone conveyor section being disposed on the ground in the operational configuration, the shiploader system having an actuator disposed to raise the truck unloader from the ground, the control system comprising:
a first pulley drive configured to drive the first head-end drive pulley;
a second pulley drive configured to the second head-end drive pulley;
at least a first truck unloader raise actuator valve, the truck unloader raise actuator valve being configured to alternately retract and extend the actuator of the shiploader system in order to alternately (a) raise the truck unloader unloading zone conveyor section from the ground to the transport configuration such that said truck unloader unloading zone conveyor section is supported by said radial stacking conveyor and disposed fully behind said radial stacking conveyor in the transport configuration and (b) lower the truck unloader conveyor section toward and into contact with the ground;
at least a first forward wheel drive configured to drive a forward wheel of a forward wheel assembly of the radial stacking conveyor, wherein said forward wheel assembly is operably coupled to said radial stacking conveyor, wherein said forward wheel is configured to transport said radial stacking conveyor in the transport configuration such that said truck unloader is transported along with said radial stacking conveyor; and
a controller in data communication with said first truck unloader raise actuator valve.
14 . The control system of claim 13 , wherein said controller is in data communication with said first forward wheel drive.
15 . The control system of claim 14 , further comprising a rear wheel drive operably coupled to a rear wheel drive.
16 . The control system of claim 15 , wherein said controller is in data communication with said first forward wheel drive and said rear wheel drive.
17 . The control system of claim 16 , wherein said controller is configured to operate said first forward wheel drive and said rear wheel drive in order to move the shiploader system alternately in a transverse direction and a rotational direction.
18 . The control system of claim 13 , further comprising:
a cross conveyor drive configured to drive a cross conveyor of said truck unloader.
19 . The control system of claim 13 , wherein said controller is in data communication with at least one of said first pulley drive and said second pulley drive.
20 . The control system of claim 13 , wherein said first pulley drive is operably coupled to the first head-end drive pulley, wherein said second pulley drive is operably coupled to the second head-end drive pulley, wherein said actuator valve is operably coupled to the actuator, and wherein said first forward wheel drive is operably coupled to said forward wheel.
