  • Patent number: 10513396
    Abstract: An extendable conveyor system with stationary and movable conveyor sections and a telescoping conveyor drive apparatus, and including a movement assembly configured to move the movable conveyor section with respect to the stationary conveyor section. The movement assembly may include teeth on one conveyor section and a teeth engaging apparatus on another conveyor section to move the movable conveyor section with respect to the stationary conveyor section. The teeth engaging apparatus may include a pin gear mounted on the second conveyor section and which has a plurality of pins positioned at radially spaced locations. A drive system may rotate the pin gear to thereby move the plurality of teeth and the first conveyor section in the longitudinal direction.
