Abstract
A heating channel for a front wall of a dump body comprises an exhaust inlet provided on the front wall; an exhaust outlet provided on the front wall; and a channel body running continuously from the exhaust inlet to the exhaust outlet. The channel body can have at least one horizontally extending portion and at least one vertically extending portion in a front view of the front wall. The exhaust inlet can be configured to receive exhaust gas output from an internal combustion engine, and the exhaust outlet can be configured to output the received exhaust gas to outside the heating channel.
Claims11
A dump body of an off-highway rear haul truck configured to be provided on a space frame of the off-highway rear haul truck, the dump body comprising:
- a bottom wall;
- a pair of opposing sidewalls;
- a front wall between the opposing sidewalls and extending from the bottom wall;
- a support structure arrangement extending from and weldably mounted on a front face of the front wall, the support structure arrangement including a first vertical support structure and a second vertical support structure separated from the first vertical support structure in a width direction of the dump body;
- and
- a continuous heating channel extending from and weldably mounted on the front face of the front wall,
- wherein the continuous heating channel is the only heating channel on the front face of the front wall and includes:
- a down-facing exhaust inlet provided at a first height on the front wall, an outward-facing exhaust outlet provided at a second height on the front wall below the first height, and a channel body extending continuously and without branching from the down-facing exhaust inlet to the outward-facing exhaust outlet, the channel body having a plurality of horizontally extending portions and a plurality of vertically extending portions,
- wherein the down-facing exhaust inlet is provided inward of first and second opposing side edges of the front wall, the down-facing exhaust inlet being provided closer to the first side edge of the front wall than to the second side edge of the front wall, and
- wherein the outward-facing exhaust outlet is provided at the first side edge of the front wall.
A heating channel for a front wall of a dump body comprising:
- an exhaust inlet provided on the front wall;
- an exhaust outlet provided on the front wall;
- and a channel body running continuously from the exhaust inlet to the exhaust outlet,
- wherein the channel body has at least one horizontally extending portion and at least one vertically extending portion in a front view of the front wall,
- wherein the exhaust inlet is configured to receive exhaust gas output from an internal combustion engine of a haul truck,
- wherein the exhaust outlet is configured to output the received exhaust gas to outside the heating channel, and
- wherein the heating channel runs, in order, horizontally from the exhaust inlet along a first horizontally extending portion of the at least one horizontally extending portion, then immediately vertically downward along a first vertically extending portion of the at least one vertically extending portion, then immediately horizontally along a second horizontally extending portion of the at least one horizontally extending portion, and then immediately vertically upward along a second vertically extending portion of the at least one vertically extending portion, and immediately toward the exhaust outlet.
