  • Patent number: 11493002
    Abstract: An exhaust gas recirculation (EGR) cooler for mounting to a coolant collector bracket may include a cooler body having a top, a bottom, a length extending in a longitudinal direction, and a width extending in a lateral direction perpendicular to the longitudinal direction, and at least one mount coupled to the bottom of the cooler body. An interior of the mount may be in fluid communication with an interior of the cooler body. A width of the at least one mount in the lateral direction of the cooler body may be equal to or less than the width of the cooler body. The at least one mount may be positioned such that the mount does not extend beyond the width of the cooler body.

  • Publication number: 20180022293
    Abstract: A bed liner system for use in a bed floor of a material hauling machine includes a lower panel that is attachable to the bed floor. The lower panel includes a first plate having a first flange, a first central opening and two first central slots disposed, one each, on either side of the first central opening. The bed liner system further includes an upper panel that is attachable to the lower panel. The upper panel includes a top plate having a second flange having a second central opening and two second central slots disposed that are aligned with corresponding features of the first flange such that a block having a top flange and a bottom flange connected by a web is insertable through the first and second central openings and slidable through one each of the two first and second central slots.
