HIGHLIGHTS

Increased Productivity with Advanced HST System, an Hitachi Original Technology

Optimum traction force can be selected to suit job needs by electronic matching control. The HST system is further improved for increased job efficiency.

Normal Operation (Work P, N and L Modes): Efficient loading with optimum traction force to suit job needs

Snow Plowing (Work S Mode): Efficient snow plowing with optimum traction force, reducing slippage on snow

Four work modes selectable to suit job needs - Work mode select switch

On Hitachi ZW140, four work modes are selectable according to job requirements and operator’s preference. In each work mode, electronic matching control, originally developed by Hitachi, detects the pressure of the implement, and controls the torque of travel motor to best match traction force and breakout force. This increases production per unit of fuel.

Four Work Modes: 

- P mode (Scooping up and crowding):

+ Relatively large crushed stones

+ Concrete slag

+ Stone with large specific gravity, clayey soil

- N mode (Normal operation) - L mode (Loading and light excavation)

+ Small crushed stones

+ Gravel

+ Cobble

+ Sand

+ Plastics, industrial wastes, chips

- S mode (Snow plowing  and swamp operation):  Snow

Matching Control

Traction force and front pressure are well balanced by work mode. If you need big traction force, select the P mode

2-Motor HST System for Powerful Acceleration and Higher Travel Speed (Maximum 39 km/h)

The two-motor HST system is newly developed to achieve high-efficient operation in a wide speed range. For instance, at a low speed, two motors yield high traction torque, while at a high speed, a single motor allows for high travel speed of 39 km/h. Moreover, this system makes possible easy slope climbing and smooth acceleration/deceleration with the accelerator pedal only.

Throttle Limit for Higher Fuel Efficiency

The throttle limit cuts maximum engine speed by 10% for higher fuel efficiency. For the HST system, maximum traction force is not reduced with the reduction in engine speed.

Throttle limit switch - *ON

- Fuel consumption (L/h): 88 %

- Production (m3/h): 93 %

- Fuel efficiency (m3/L): 106 %

*Index: 100 = Throttle limit switch OFF. Note: Data shown is Hitachi test data, and may vary depending on job conditions.

Improved Fundamental Performance

Big Traction Force: 

- Traction force: 87kN

- Bucket breakout force: 92kN

Big Dumping Clearance and Reach (when 2.0 m3 bucket with BOC is fitted)

- Dumping clearance: 2 840 mm

- Dumping reach: 900 mm

Smooth Speed Shift by Electronic ControlSpeed shift can be continuously made  by electronic control through the 2-motor HST system comprising helical gears. This allows for speedy job-to-job travel with less soil spills in load-and-carry operation.

High-Torque Engine

Max. output : 96 kW (129 HP)

Max. torque : 540 N∙m (55 kgf∙m)

The new engine is ruggedly designed to yield big torque with less vibration for increased durability. This facilitates climbing steep slopes and long uphills with limited speed drop. This engine is a clean engine that complies with the latest global emission regulations.

Torque Proportional Differential  (Standard)

The torque proportional differential adjusts driving forces to both wheels. When road resistances under both wheels are different, this feature minimizes slippage of a wheel on softer ground, unlike conventional differentials. This feature enables the ZW series to get out of swamps or rough terrain easily.

Limited Slip Differential (Optional)

On snowy roads and rough terrain, the limited slip differential can work instead of the torque proportional differential. This delivers effective driving force to both wheels for enhanced grip and less slippage during travel.

Agile Footwork for Increased Productivity

Fast, light footwork. Speed selection to suit job needs. Improved controllability and combined operations. Those bring about high productivity

Sophisticated Mechanisms for Higher Job Efficiency

Float System: The float system lets the lift arm follow up road irregularities by using its selfweight only, without using its hydraulic circuit. This system is useful in soil-spill collecting during loading, and snow removing

Lift Arm Kick-Out System (Optional): The lift arm can automatically be raised up to the preset level. This function is convenient when loading onto a dump truck, and when operating at confined job sites with restricted working height.

Bucket Auto Leveler: The bucket can automatically be leveled parallel to the ground after dumping the bucket. This can eliminate cumbersome bucket repositioning for efficient loading.

Operator-Friendly Designs for Higher Job Efficiency

Restriction Valve: The restriction valve can effectively reduce shocks when stopping the lift arm. The bucket does not have a shockless circuit to allow efficient mud removal.

Ride Control System (Optional): The ride control reduces pitching and bouncing during traveling on rough terrain and snow road by automatic control of the implement. Shocks and vibration can be well suppressed for riding comfort

Advanced Speed Selector for Four Maximum Speeds

The fully automatic HST system is utilized for the selection of four maximum speeds according to job needs. Optimum speed can be selected with less shocks for smooth travel.

The First Speed Selector for Efficient Loading and Operations in Confined Space

When the first speed range is selected, four travel speeds can be further selected to suit job needs and jobsite conditions. No need for skilful control of the accelerator and brake.

Inching Pedal for Easy Positioning in Confined Space

The operator can easily control travel speed with the inching pedal, regardless of the accelerator pedal, by adjusting the delivery flow from the hydraulic pump. This eases positioning in loading operation.

New Hydraulic Circuit for Smoothly Combined Operation

With the new parallel/tandem hydraulic circuit, the lift arm and bucket can be operated simultaneously. This is a new function to increase loading and excavating efficiency

Operator-First Designs: Easy-to-Handle Controls for Operator Comfort

Environmentally Friendly Design

The ZW Series is equipped with a clean but powerful engine to comply with Tier 3 and Stage III A. An engine emission regulations effective in the U.S. EPA and European Union from 2006. Exhaust gas is partly re-combusted to reduce particulate matter (PM) output and lower nitrogen oxide (NOx) levels.

Common Rail Type Fuel Injection System

In this fuel injection system complying with the Emission Regulations, one fuel pump runs to generate high pressure for distributing fuel to each injector per cylinder through a common rail. By electronic control, fuel injection volume and timing can be precisely regulated for efficient combustion and higher horsepower. This also reduces PM* (diesel plume), fuel consumption and vibration.

*Particulate matter

Important: The use of fuels other than diesel fuel (EN590) is prohibited. Otherwise, the engine may be damaged.

A Recyclable Machine

Approximately 95% of the ZW Series can be recycled. The resin parts are marked to facilitate recycling. The machine is completely lead-free. The radiator and oil cooler are made from aluminum and all wires are lead-less. In addition, bio-degradable hydraulic oil is available for jobsites where special environmental care is required.

A number of features make this machine quieter. First, isochronous control of the engine speed means a restriction of engine speed during no-load and light-duty operation to suppress sound. A fan with curved blades reduces air resistance and airflow noise. Third, a time-tested muffler suppresses engine noise significantly and reduces emissions. This advanced low noise design complies with the 2000 / 14 / EC, Stage II, directive effective in the European Union from 2006.

Hitachi Silent (HS) Fan

The HS fan is capable of reducing air resistance and air flow sound are utilized at the radiator and oil cooler for quieter operation.

Low Noise Engine

Engine noise is effectively reduced by increasing engine mechanical strength with rigid cylinder block, and by utilizing the elaborate gear train on the flywheel side.
