FEATURES

  • Power Train – Cat® 3412E air-to-air after cooled diesel engine features Hydraulic Electronic Unit Injector (HEUI™) for efficient operation. High displacement/low speed rating extends engine life. Cat 3412E meets U.S. EPA Tier 2 equivalent/China Nonroad Stage III emission standards. The 33% torque rise provides high lugging force during acceleration and less down shifting on grade or in rough underfoot conditions. The torque rise effectively matches the transmission shift points to provide maximum efficiency and faster cycle times.
  • Fuel Economy – The 773E fuel saving strategies find opportunities to reduce fuel burn and fuel costs. 1) Economy Mode modifies engine maps to take advantage of steady grades and level ground, reducing power and fuel burn. 2) Speed Limiting automatically selects the most fuel efficient gear and speed for the terrain at each moment. 3) Engine Idle Shutdown identifies when the truck is in park and idles for more than a preset time, and initiates engine shutdown to conserve fuel. This feature can be time adjusted or turned on or off according to your specific needs. 4) Engine Over Speed Protection – Electronically senses engine conditions and automatically up-shifts one gear to prevent over speeding. For machines with ARC, if over speeding occurs in the top gear, the lock-up clutch is disengaged, and the brakes are applied.
  • Serviceability – The improved accessibility for radiator coolant and engine oil fill point improves serviceability. Safe, convenient maintenance with a machine platform and ground level battery disconnect. The new instrumentation and Advisor system provides a 3-category warning system and quick access to stored diagnostic data. The Advisor provides quick on-board diagnostics, reduces downtime and lowers operating costs. Radial seal filters are easy to change, and vertical, spin-on filters simplify servicing. Quick coupler taps and S·O·SSM analysis points make oil sampling quick and clean. Sealed electrical connectors lock out dust and moisture. Color-coded wiring is standard.
  • Diagnostic Capability – Critical power train data, including transmission shifting, engine speed and fuel consumption, provides service technicians with enhanced diagnostic capability to reduce downtime and operating costs.
  • Electronic Technician (ET) – Cat ET service tool provides service technicians with easy access to stored diagnostic data through the Cat Data Link.
  • Cab and Access – The 773E cab interior, is completely redesigned to provide better visibility and comfort for the operator. Features include a new dash, advisor display and redesigned center console. Rollover and Falling Object Protection is an extension of the truck frame.
  • Operator Seat – The Cat Comfort Seat uses full air suspension to smooth rough rides, and has a retractable four-point seat belt with a shoulder harness. A trainer seat with a lap belt to facilitate on-the-job task training.
  • Brakes – The Cat front dry caliper with rear oil-cooled multiple disc brakes deliver reliable performance and control in the most extreme haul-road conditions. Speed limiting during body up operation is standard. Oil-cooled rear disc brakes are designed and built for reliable, adjustment-free operation providing superior performance and service life in comparison to shoe-type and dry-disc systems. The system combines service, retarding and parking brake functions in a single unit.
  • Automatic Retarder Control (ARC) (optional) – ARC controls braking on grade electronically, maintaining consistent engine speed, lower fuel burn, and better control.
  • Traction Control System (TCS) (optional) – The traction control system monitors wheel slips so if it exceeds the set limit, the oil cooled disc brakes are automatically applied to slowdown the spinning wheel.
  • Steering – Cat integrated steering and suspension system is designed for precise steering, excellent maneuverability, minimal tire wear and superior ride control. Secondary steering automatically engages if power source for the normal steering fails.
  • Durability – Rear wheel spindles are solid steel for longer life, and the rear cylinders are inverted to protect the rods from debris. These rugged cylinders use large diameter bore and low pressure nitrogen/oil design for long life with minimal maintenance.
