The New Generation Hydraulic Excavators The HITACHI ZAXIS-3 series new-generation hydraulic excavators are packed with a host of technological features clean engine, HITACHI advanced hydraulic technologies, with strong undercarriage and front attachment, plus well matching of power and speed. ZAXIS 520LCH’s large 60-ton class undercarriage components provide greater travel performance and durability on tough ground conditions.
Clean engine complies with the emission regulations US EPA Tier 3 and EU Stage III A Low noise design complies with the EU noise regulation 2000 / 14 / EC, STAGE II
A Solid Base for a Long Life Strengthened undercarriage for higher durability even in heavy-duty applications.
Strengthened Undercarriage Pressed Master Pins The master pin of each track link is pressed, instead of the master pin using a pin retention to avoid disengagement.
Increased Loading Capacity of Swing Circle The swing circle ball bearing utilizes more balls to boost the loading capacity of the swing circle by approximately 6%, allowing stable swing even in tough operation*.
Increased Traction Force
Strengthened Upper Roller Bracket
On the ZAXIS 520LCH, distance between tumblers is shortened, compared to that of the new ZAXIS 470LCH, to increase traction force by 30%. The feature is suitable for frequent hill climbing and traveling on hard ground surfaces.
The upper roller bracket wall thickness is increased for higher strength.
* vs. Conventional model
Enlarged Upper and Lower Rollers, Idlers and Sprockets Upper and lower rollers, idlers and sprockets, used on the ZAXIS 520LCH, are larger in diameter than those on the new ZAXIS 470LCH. Undercarriage components capable of bearing a 60-ton class excavator are utilized to give sufficient strength and durability. This feature is suitable for worksites when the machine travels frequently.
Full Track Guard Provided Standard Full track guards are provided standard. Full track guards protect track links and lower rollers from damage and deformation. Moreover, they also keep out stones, preventing the overload to the undercarriage to reduce wear and damage.
Strengthened Front Attachment 5% Increase in Strength with Stronger Pin Material The strength of pins, used in the arm and boom, is increased by 5%, using harder steel material*.
Strenghtened H-Bucket for Heavy-Duty
Strenghtened General-Purpose Bucket
The heavy-duty bucket is reshaped, and bucket parts are strengthened to increase durability.
Bucket teeth are reshaped as Super-V teeth for smooth penetration and higher production. Bushings are utilized at both ends of a bucket pin to eliminate clearances, preventing jerky operation.
* vs. Conventional model
World-Class Productivity To yield high production yet maintain low fuel consumption, such was the objective of the development of a new engine and hydraulic system for the ZAXIS 520LCH.
Production: Approx. 14% Increase Fuel Consumption: Approx. 13% Reduction (vs. Conventional Model)
Advanced Hydraulic Technologies Increased Digging Force
Boom Mode Selector
Combined Operation of Boom and Arm
7% more bucket digging force and 8% more arm digging force*.
The amount the body can be lifted or pulled by the front of machine can be ON or OFF selected. This helps to provide for more comfortable operation and contributes to longer component service life.
In combined operation of swing + boom lower + arm roll-out, or in leveling (boom lower + arm roll-out), arm roll-out speed can be increased greatly. Here’s why. A variable throttle, provided in the arm circuit, adjusts the flow when needed to reduce hydraulic loss in combined operation with arm roll-out.
* At power boost mode / vs Conventional model
Enhanced Boom Recirculation System In combined operation of boom lower and arm, arm speed can be increased by approximately 15% over the conventional. Pressurized oil from boom cylinder bottom side is delivered to boom cylinder rod side to lower the boom, assisted by boom weight. Conventionally, pressurized oil from pump is delivered to boom cylinder rod side to lower the boom. The new system also allows for an efficient combined operation of swing and lowering the boom.

Boom Lower Bucket Roll-Out
P M
New Bucket Regenerative System Larger-Diameter Front Piping
15% UP
Arm piping is increased in diameter to reduce hydraulic loss (theoretically 7%) for speedy front operation.
Swift bucket actions can be done in combined operation for excavation through the new bucket regenerative circuit. When the load to the bucket is light, pressurized oil from bucket cylinder rod side is delivered through a regenerative valve to bucket cylinder bottom side for the effective use of hydraulic energy.
Development Concept of New Engine High Power Yet Low Fuel Consumption
Common Rail Type Fuel Injection System
Cooled EGR** System
4% Increase in output (vs. Conventional model) • 260 kW (349 hp) /1 800 min-1
Electronic control common rail type fuel injection system drives an integrated fuel pump at an ultrahigh pressure to distribute fuel to each injector per cylinder through a common rail. This enables optimum combustion to generate big horsepower, and reduce PM* and fuel consumption.
Exhaust gas is partially mixed with intake air to lower combustion temperature for reducing NOx and fuel consumption. What’s more, the EGR cooler cools down exhaust gas to increase air concentration for complete combustion, reducing PM*.
The new clean engine, complying with the emission regulations Tier 3 in US (EPA) and EU Stage III, can reduce fuel costs by electronic control.
