Abstract: An exhaust discharge system is disclosed. The exhaust discharge system comprises an exhaust stack including a first conduit and a second conduit. The first conduit defines a first flow passageway and arranged around a first longitudinal axis. The first conduit including a skirt portion and a body portion disposed downstream of the skirt portion, and the skirt portion is oriented to slope outward from the body portion. The second conduit is disposed downstream of the first conduit. The second conduit defines a second flow passageway and is arranged around a second longitudinal axis, the second conduit includes a sidewall and an exit port, the exit port having an exit-port cross-section, wherein the exit-port cross-section is oblong in shape. The second longitudinal axis is disposed at an intersection angle to the first longitudinal axis, the intersection angle in a range of 125° to 150°. The exhaust stack is configured to convey treated exhaust from the skirt portion to the exit port.

Abstract: A construction vehicle includes a chassis having a front end and a rear end. The construction vehicle also includes an operator cabin supported by the chassis and a hood proximate to the rear end of the chassis. The construction vehicle further includes a hood structure for supporting the hood. The hood structure includes a first frame member coupled to the chassis proximate to the rear end and a second frame member disposed distal to the rear end and proximal to the operator cabin. The second frame member is coupled to the chassis by a mounting assembly. The mounting assembly includes a plate member connected to the second frame member. The mounting assembly also includes a first mounting device connecting a first end of the plate member to the chassis. The mounting assembly further includes a second mounting device connecting a second end of the plate member to the chassis.
