Shiploading systems, methods and apparatus

A shiploader control system for a shiploader system having a transport configuration and an operational configuration, the control system comprising:

• a first pulley drive configured to drive a first belt-driving pulley of a radial stacking conveyor of the shiploader system;
• a second pulley drive configured to drive a second belt-driving pulley of a truck unloader of the shiploader system;
• at least a first truck unloader raise actuator valve, the truck unloader raise actuator valve being configured to alternately retract and extend an actuator in order to alternately raise and lower a truck unloader of the shiploader control system relative to the radial stacking conveyor such that the truck unloader raises and lowers from the ground while the radial stacking conveyor remains on the ground;
• at least a first forward wheel drive configured to drive a transversely extending forward wheel of a forward wheel assembly of said radial stacking conveyor in order to pivot said radial stacking conveyor about a vertical axis;
• and
• a controller in data communication with each of said first pulley drive, said second pulley drive and said first truck unloader raise actuator valve.
