D7E Dredging Arrangement Key In Beach Restoration

The Cat® D7E Dredging Arrangement is designed to withstand the severe conditions encountered in dredging and enables greater productivity with improved fuel efficiency. The Tier 4F engines burn from 10 to 30 percent less fuel per hour to help achieve reduced operating costs.

“I think we are saving a good 25 percent on fuel costs every day on our D7Es,” says Great Lakes Dredge & Dock (GLDD) field operations supervisor James Janus. “And the availability of the machines has been very good.”

The AccuGrade™ on the D7Es greatly improves production and helps the operators hit grade much faster, Janus dds. It eliminates the need for grade conduits and ground personnel and speeds things up for GLDD’s operators by indicating their exact location on the template while dozing in the watery, sandy environment

“The D7E has plenty of power, traction and good blade control—it’s like a little pit bull,” adds operator Jim Souner. “These D7Es are tough machines—they take a beating in the sand and saltwater but they keep pushing and hold up well.”

“I would recommend the D7E Dredging Arrangement to other companies for sure,” Janus says.

The D7E is also easily transportable during mobilization and demobilization.

Purpose built for use in the severely abrasive dredging environment of water fording in sandy, saltwater applications, the D7E Dredging Arrangement includes:

  • Corrosion-resistant paint
  • Specialized engine enclosure door covers
  • Corrosion-resistant components and wiring
  • One-piece sprocket segment
  • Removal of radiator grill door and specialized undercarriage
  • Protective seal-saver boot
  • Plus other modifications

The D7E Dredging Arrangement optimizes productivity, durability and fuel efficiency to combat and withstand the severely abrasive conditions of a dredging application, enabling the D7Es to perform better and last longer.
