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
+ Plastics, industrial wastes, chips
- S mode (Snow plowing and swamp operation): Snow
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.
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.
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
The panoramic cab gives almost allround visibility with the widened front glass window and pillar less cab rear corners. Front wheels are always in the operator's vision, enhancing safety and increasing loading efficiency.
Enhanced Upward Visibility
The front curved glass window gives good upward visibility, so the operator can directly see the movement of the bucket for safer loading.
Good Rear Visibility
The engine cover is low profile, and rounded for better rear visibility, so the operator can directly see the rear wheels and counterweight.
Comfort-Designed Suspension Seat

Front / Rear Defrosters
With the front and rear defrosters, airflow comes out from three front air outlets and two rear outlets to protect respective windows from fogging, keeping clear vision even in rain and cold weather.
The cab rests on fluid-filled elastic mounts to absorb shocks and vibration, and reduce resonance.
Hat (Resin Cab Roof)
The hollow hat is provided atop the cab to form an air space. This greatly helps reduce the temperature rise in the cab, and increases the cooling efficiency of the air conditioner.
