Bin sweep system

A bin sweep system for moving particulate material in a bin may comprise an elongated sweep apparatus having a particulate sweep structure configured to move particulate material on the floor beneath the sweep apparatus toward one end of the elongated sweep apparatus. The particulate sweep structure may include a plurality of interconnected paddles movable in a succession on a path along at least a portion of a length of the sweep apparatus and an endless loop member on which the paddles of the plurality of paddles are mounted at spaced locations for moving the paddles along the path. The path of the paddles on the endless loop may generally lie in a movement plane, and an orientation of the movement plane may be tilted such that the movement plane is not in a vertical orientation and not in a horizontal orientation.
