ABSTRACT:
An excavating and loading system is disclosed which includes a vehicle with an excavating wheel assembly, at the front and a plurality of conveyors toward the rear. The excavating wheel assembly comprises individual excavating wheels including a plurality of digging buckets. Each bucket comprises a wall supported for pivotal movement between a material receiving position and a material dumping position. A plurality of push rods are each connected at one end to the movable wall of one of the buckets. A rigid collar is interconnected to the ends of the push rods remote from the movable walls which collar is rotatably supported at a point offset from the rotational axis of the excavating wheel so that the push rods and the collar cooperate to positively pivot the movable walls of the bucket between material receiving and material dumping positions.
