The assembly includes a pair of spaced apart side plates having a plurality of wheel mounting openings therethrough. The side plates have a frame connection opening therethrough. The assembly further includes a plurality of support wheels disposed between the side plates, each of the support wheels including a wheel axle receiving opening therethrough. A center support wheel has a diameter that may be greater than the diameter of two outer support wheels. The assembly further comprises an axle disposed through the wheel mounting openings of the side plate and through the shaft receiving openings of the support wheels to thereby support the support wheels between the side plates while allowing rotation of the support wheels. The assembly further comprises a continuous track disposed about the support wheels. ## Claims ### Claim 1 A continuous track attachment assembly adapted to be used on conveying equipment comprising: a pair of spaced apart side plates having a plurality of wheel mounting openings therethrough, the side plates having a frame connection opening therethrough; a plurality of support wheels disposed between the side plates, each of the support wheels including a wheel axle receiving opening therethrough; an axle disposed through the wheel mounting openings of the side plate and through the wheel axle receiving openings of the support wheels to thereby support the support wheels between the side plates while allowing rotation of the support wheels; a spindle having a shoulder, and wherein at least one of the side plates incudes a pocket having a bearing disposed in the pocket, the spindle at least partly received in an opening of the bearing, and the shoulder engaging the side plate; and a continuous track disposed about the support wheels. ### Claim 2 (depends on 1) An assembly as set forth in claim 1 wherein the plurality of support wheels comprises a center wheel having a center wheel periphery defining a center wheel outer diameter, and first and second wheels each having a periphery defining an outer diameter, the center wheel outer diameter is greater than the outer diameters of the first and second support wheels. ### Claim 3 (depends on 2) An assembly as set forth in claim 2 wherein the outer diameter of the first wheel is the same as the outer diameter of the second wheel. ### Claim 4 (depends on 2) An assembly as set forth in claim 2 wherein the continuous track forms a V-shape when disposed about the support wheels, having at least an apex below the center wheel. ### Claim 5 (depends on 4) An assembly as set forth in claim 4 wherein each of the support wheels includes a wheel bearing receiving pocket. ### Claim 6 (depends on 5) An assembly as set forth in claim 5 wherein each of the support wheels includes a bearing disposed in the wheel bearing receiving pocket, the bearing including an opening therethrough. ### Claim 7 (depends on 6) An assembly as set forth in claim 6 wherein the frame connection openings are adapted to receive an axle therethrough. ### Claim 8 (depends on 6) An assembly as set forth in claim 6 wherein each side plate includes a boss defining a bearing receiving pocket for receiving a bearing and a boss opening. ### Claim 9 (depends on 2) An assembly as set forth in claim 2 wherein the continuous track has an inner portion having a plurality of teeth and an outer portion having a tread. ### Claim 10 (depends on 9) An assembly as set forth in claim 9 wherein the assembly is connected with coupled to the conveying equipment. ### Claim 11 (depends on 1) An assembly as set forth in claim 1 wherein each of the side plates includes a spacer, the spacers engaging each other to inhibit flexing of the side plates. ### Claim 12 (depends on 1) An assembly as set forth in claim 1 wherein at least one of the side plates includes a notch. ### Claim 13 (depends on 1) An assembly as set forth in claim 1 wherein the spindle has a pair of shoulders, and wherein each of the side plates incudes a pocket having a bearing disposed in the pocket, the spindle at least partly received of the bearings, and each shoulder engages a respective side plate.
