Lightweight bodies are the ideal choice for mines looking to optimize payload. Mines that choose these bodies should have excellent loading practices, good blasting practices, and a solid maintenance program supported by resources such as facilities, personnel and expertise.
High Efficiency Bodies are the first fit and ideal replacement body for Cat® 794, 796 and 798 electric drive trucks.
The high-efficiency (HE) dump body is lightweight, simplified and durable. Featuring a unique, primarily bolsterless design, the HE body provides long life while minimizing weight for increased payload. The HE body is sized and configured to meet the specific needs of the mine, dictated by fragmentation, abrasion, cohesion and the loading tool.
The structural perimeter beam — along with curved floor, front wall and canopy — provides the natural strength and stiffness required to successfully operate in diverse mining applications.
High-strength base plates allow for a minimal wear package, resulting in lower weight.
The patented designs of the floating bolster and spring plate improve overall durability by allowing structural flexibility and avoiding welds in high stress areas.
Nearly 200 HE bodies have been produced to date with close to 4 million accumulated hours of operation. These bodies are demonstrating success in all major mining environments – coal overburden, copper, iron ore and oil sands. They feature numerous patented design features and their two-piece shipping configuration reduces field weld inches. Benefits include:
Fuel consumption reduction
Cycle time reduction
Tire life increase
