A boom conveyor apparatus includes a boom that carries a conveyor, a support structure for the boom, a rear pivot joint that connects a rear end of the boom to the support structure, and a pivot drive that controls pivoting movement of the boom about the rear pivot joint. The boom conveyor apparatus includes an operator platform and an attachment mechanism at a front end of the boom whereby the operator platform may be attached to the boom or detached therefrom. The attachment mechanism includes a levelling mechanism that is configured to apply a levelling adjustment to the operator platform.

A telescopic conveyor includes a conveyor boom having two or more conveyor sections adapted to be extended and retracted with respect to one another in telescopic fashion to adjust the length of the boom, wherein the two or more conveyor sections are each curved about a common axis of curvature.

The present invention provides an article alignment device that can inhibit posture disorderliness when articles land on a conveyor belt. The posture of bags when the bags transfer from an input conveyor to a first aligning conveyor is inclined in such a way that the portions of the bags that land on bags already placed on the first aligning conveyor are higher and the portions of the bags that land directly on the first aligning conveyor are lower, so the bags land on the first aligning conveyor before or at the same time that they contact the bags that were placed on the first aligning conveyor before them. Additionally, the frictional force between the first aligning conveyor and the bags is greater than the frictional force between the bags, so sliding between the bags is prevented, as is posture disorderliness.

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.
