Hitachi EX1200-7

Features

• A redesigned hydraulic oil cooler with variable speed fan reduces energy demand and creates a more reliable hydraulic system.

• The cab rests on 6-point, support type, fluid-filled elastic mounts. These significantly reduce shocks and vibration for operator comfort and improve cab durability.

• With Global e-Service, an online machine management system, you can access each on-site machine from a PC in your office. You can get its operating information and location to increase productivity. Operating data and log are sent to a Hitachi server for processing, and then to customer and dealers. This system is available 24/7/365.

• Floating pin design is adopted for bucket linkage. This helps to reduce wear by evenly distributing the load around the pin and minimizing dust ingress. A replaceable thrust plate minimizes maintenance time caused by extreme contact wear to the surface.

• Fuel Consumption Optimization (FCO) technologies improve total fuel economy by 6 percent* through engine options and hydraulic system improvements (*comparison of Cummins engine configuration against the EX1200-6).

• The proven Hitachi-patented track shoe design mitigates premature wear of the drive-lugs. Each shoe is induction hardened, utilizing Hitachi’s unique processes to deliver a more durable solution.

• Contamination sensors are located on all main hydraulic pumps to detect any contaminants that may cause damage to the hydraulic system.

• The advanced hydraulic system tops the industry for smooth, efficient, combined operations of the front attachment and swing, delivering quick cycle times.

• If load to the hydraulic system becomes excessive while the boom is being lifted, an automatic change in the main relief pressure setting will increase lifting power, improving operability and efficiency.

• Wide center walkways and open service areas offer ease of access for daily maintenance tasks and make engine, hydraulic and electrical component inspections easy.

• Computer assisted analysis is used to determine the most effective design for frame longevity to withstand the demands of the mining operation.

• The Level II Operator Protective Guard (OPG) provides protection from falling objects, ensuring an added layer of safety and assurance to the operator.

• A dial-type multi-functional controller makes operation easy and intuitive. Frequently used switches are located on the right-hand side console panel within easy reach of the operator.

• Radiator and oil cooler fans can be reversed to eject dust on cores and screens. This reduces the need for labor-intensive maintenance and extends the life of components.

• Each individually controlled hydraulic pump has its own electric regulator, enhancing engine power, lowering fuel consumption, and increasing productivity to lower the total cost of operation.

• Frequently accessed filters are now conveniently located in the center access way.

• The control of both the arm and boom is achieved through a Hitachi proprietary leveling cylinder mechanism, using just one arm lever. This means the bucket can automatically be pushed out horizontally using a single movement.

• The underslung low bend configuration of the front attachment hoses removes the need for clamping to help reduce chafing and increase reliability.

• Tinted, laminated windows and retractable front and side roll screens help to reduce heat, glare and harmful UV rays.

• Hitachi’s exclusive center track frame delivers optimal stress dispersion through the use of specifically designed castings to reduce welds in critical high stress areas, ensuring a stronger frame with improved durability and reliability.

• The EX1200-7 comes with an optional auto-lubrication system for a bulk excavation front attachment, which supplies grease to the superstructure including bucket pins.

• When digging in hard rock environments, Power Boost Switch can be temporarily activated to increase pump pressure and maximize hydraulic power in the front attachment.

• The automatic weight-adjusting air suspension seat determines the optimal cushioning effect to match the operator’s weight, enhancing comfort and minimizing vibration.

• The optional Aerial Angle system provides the operator with a real-time birds-eye view around their excavator. Cameras strategically mounted on the machine combine to a single aerial view of the EX2600-7 surroundings. Multiple screen display options can be selected on the cab’s 7-inch Aerial Angle monitor for ease of operation.

• The redesigned center joint employs the machine’s hydraulic oil to self-lubricate, reducing daily maintenance.

• A forged swing circle distributes stress evenly around the most demanding areas of the component, improving machine sturdiness.

• The Cummins engine is available in Final Tier 4 (FT4) or Fuel Calibration Optimized (FCO) configurations.

• The multi-functional display provides key machine information, performance indicators and on-board troubleshooting functionality through the use of the integrated dial switch interface. It’s fitted with an LED backlight to provide improved clarity with reduced glare and reflection.

• The pressurized cab’s climate controlled air conditioning helps to overcome environmental extremes.
