Cat® 773E
- Nominal Payload
- 55.5 t
- Engine Model
- Cat® 3412E
- Top Speed
- 62.2 km/h
- Description
-
- Designed for performance, designed for comfort, built to last.
MORE POWER
Maximize power to the ground with an increase in torque and a higher speed on grade
MAXIMIZING EFFICIENCY
Experience higher levels of efficiency using advanced engineering and software
ENHANCED SAFETY
Grouped, ground level engine and machine controls allow for safe and easy daily maintenance
Allows faster engine service (changing most oil and filters). Improves service scheduling, allows servicing during normal work hours and reduces total engine service time.
The four stroke design uses long power strokes for complete fuel combustion and optimum efficiency. High displacement/low speed rating extends engine life and meets China Nonroad Stage II Emissions Standards.
The ARC electronically controls braking on grade to maintain approximately 2,230 rpm (engine rpm is adjustable from 2,150-2,300 rpm in increments of 10 rpm). ARC is deactivated when the operator applies the brakes or throttle.
The ROPS/FOPS cabin has electric power window, electro-hydraulic hoist lever, trainer's seat, front brake cut-off switch, backlit LED gear numbers, and optional heater and air conditioner.
The 773E frame uses 20 castings in high stress areas with deep penetrating and continuous wrap-around welding. Mild steel provides flexibility, durability and resistance to impact loads even in cold climates.
High rimpull and cushioned shifts with direct drive's efficiency and performance.
