Hitachi introduced the EX1200-7 excavator, which will provide increased efficiency, reliability and durability for customers. The excavator is the third machine in Hitachi’s new EX-7 series lineup, following the recent launch of the EX2600-7 and EX5600-7.

“Available in a backhoe or shovel configuration, the EX1200-7 is our smallest mining excavator and also serves as a crossover machine for construction customers,” said Brian Mace, mining product marketing & applications manager, Hitachi Construction Machinery – Americas. “This versatile machine delivers an astounding combination of power and the latest technologies you need to get the job done, whether its large-scale excavation or mining.”

The EX1200-7 excavator features Fuel Consumption Optimization (FCO) technologies that improve total fuel economy by 6% (compared to the EX1200-6) through engine and hydraulic system improvements.

  • Cummins Tier 4 Final engine with DEF, plus auto-idle to reduce engine speed and save on fuel consumption (Note *: Only Cummins engine will be available)
  • 9.2-cu.-yd. bucket capacity (+4.5%)
  • Improved hydraulic system with flow regeneration valve to reduce power requirements from the hydraulic system and engine
  • Undercarriage includes  three single-sided upper rollers on each side of the track frame that help maintain track shoe clearance and reduce debris buildup
  • Welded, full-box section design boom and arm evenly distribute stress and provide ease of maintenance
  • Optional auto-lubrication system for a bulk excavation front attachment
  • Cab rests on six-point, support-type, fluid-filled elastic mounts
  • Improved track link design mitigates premature failure of the master pin while oil-filled idlers and rollers eliminate the need for daily lubrication
  • Pressurized cab with climate-controlled air conditioning, weight-adjusting cushioned seat, large, multi-functional display with an LED backlight and optional sun visor and roll screen
  • Optional Aerial Angle system features a display monitor that combines a set of images captured by cameras positioned at different locations around the machine
