7% Down Fuel Consumption*  


Hitachi fuel-saving technology is more evolved than ever. The electronically controlled engine can curb fuel consumption behind the electronic governor, clutch fan, and isochronous control, which is one of fuel-saving technologies that can automatically control engine rpm through the electronic governor. This can suppress wasteful engine speed increase when big
output is not needed, leading to less fuel consumption.


*Hitachi measurements in P mode under standard digging test conditions


22% Up Engine Torque


The new engine is designed to increase its maximum torque to keep running without speed drop at high altitudes with thin air and in hot summer season. At its maximum torque, the speed is kept low to ensure stable performance even under heavy loads.


Improved Heat Balance


Even at high temperatures in summer or in continuous long hours operation, Hitachi ZX70 can lessen overheating, as cooling efficiency increases: heat balance is up 4% in engine coolant, and up 12% in hydraulic oil, compared to the conventional.


Low-Effort Pilot Lever


The new fingertip-control pilot lever reduces operator fatigue in long hours operation. This pilot lever resembles the one proven on the ZX200 in the larger class.


Highest Criteria of Sturdiness and Durability Gives Higher Productivity

WC Thermal Spraying at Arm-Bucket Joint


WC (Tungsten-Carbide) thermal spraying is applied on surfaces of the arm-bucket joint to form hardening layers to reduce wear and jerking significantly.


Reinforced Bucket (Optional)


The flat bottom type bucket protects its welds with wear plate. The 0.28 m3 reinforced bucket is provided optional with reinforcing plates at its bottom.  


4-Side Reinforced Arm (Optional)  


The arm top is strengthened with reinforcing plates on its four sides to withstand high loads.  


Track Frame Undercover (Optional)

Full-Auto Air Conditioner (Standard)


The full-auto air conditioner can keep preset in-cab temperatures by blowing fresh air. Air flow and outlets are adjusted automatically. Bi-level air flow makes it possible to warm leg space and cool head space simultaneously.


Neutral engine start system


The pilot control shut-off lever is provided with a neutral engine start system that permits engine starting only when the pilot control shut-off lever is in Lock position.




The CRES cab is reinforced with high-rigidity steel tubes at corners to significantly increase strength and rigidity for higher safety.

Fuel Double-Filters (Standard)


Fuel double-filters are utilized in a fuel line from fuel tank to engine to avoid plugging. Also, a solenoid fuel pump is provided standard to release air if water is mixed in fuel or fuel runs out.


Dust-Proof Indoor Net


The radiator is provided with a detachable dust protective net at its front to avoid dust entry. The net is made of three-split type for easy, quick servicing. An air nozzle port at the radiator top facilitates cleaning.


Easy-to-Clean Big Fuel Tank  


The fuel tank has the ample capacity of 135 litters. Its inlet is sealed with a keyed cap for water proof type. At the bottom of the fuel tank a drain cock, which serves to easily discharge contaminants inside, and a bolted cleaning port for easy opening and cleaning.


Battery Disconnect Switch (Optional)


This battery disconnect switch is provided to avoid battery discharging and protect harnesses when the machine is not in use in winter or in long-term storage.

Hitachi Global Online Network, a parts supply system, is linked with Japan Parts Center, overseas depots and over 150 dealers abroad to deliver on-line parts information, including in-stock parts, order receptions, shipments and delivery period of over one million parts and components.


Genuine Hitachi Parts


Genuine Hitachi parts, meeting Hitachi stringent quality standards, are guaranteed according to Hitachi warranty standards. The use of genuine Hitachi parts, including engine, fuel, hydraulic oil and filters, may slash running costs, and extend machine life.


Ground Engaging Tools (GETs)


Hitachi provides an array of Hitachi Ground Engaging Tools developed and built for a variety of applications. Using high-quality, well-maintained GETs will help you get customers' trust.


Note: Some dealers do not handle Hitachi GETs.


Remanufactured Components


Hitachi components are remanufactured according to the stringent remanufacturing standards at four factories around the world. They have high quality equivalent to new ones, and backed up by Hitachi warranty system.


Note: Some dealers do not handle Hitachi Remanufactured Components.



Extended Warranty - HELP


Hitachi Standard Warranty System is available on all new Hitachi machines. In addition, Hitachi offers Hitachi Extended Life Programs (HELPs) to suit customer expectations - protecting machines under tough operating conditions, avoiding unexpected downtime, and reducing repair costs.


Note: Warranty conditions vary by equipment.


Diagnostic Tools - Maintenance Pro


Electronic control system needs quick on-site solutions, apart from mechanical repairs. Hitachi’s Maintenance Pro can diagnose machine failures in a short time by plugging a PC into a failed machine.


Technical Training


On-site servicing matters despite locations to keep the machine at peak performance and reduce downtime. Technical Training Center (TTC), located in Japan, educates and trains service technicians and service support personnel coming from Hitachi dealers and factories on the globe according to the international training programs
