When you sit inside the cab of a ZW wheel loader, you’ll see that it offers exceptional all-round visibility. Switch on the engine and you’ll hear that it’s the quietest machine on the market. When you start work, you’ll feel the benefit of the comfortable seat, easy-to-use controls and smooth operation.
We know our compact, medium and large wheel loaders not only appeal to your senses, but also make sense for your business. With substantial loading capacity, powerful digging force and impressive travel speeds, they’re extremely productive. Fuel-efficient and easy to maintain, they offer reduced running costs. Used with a variety of attachments, they are easily adaptable for different tasks.
We understands very well the types of construction machinery and equipment suitable to the construction, financial and operational conditions of Vietnamese contractors. We currently supply all kinds of HITACHI equipment such as Mini excavators (with a working load of 800kg) to large mines (up to 533 tons largest), wheel loaders, Ben runs in the mine with a load of 180t or more.

Durability and Reliability are enhanced with a number of advanced mechanism for long, continuous operation.
Improved Drive System for Higher Reliability and Maintainability
Kubota V3800 DI-T/TI engine, already mounted on numerous equipment, has proved ruggedness and reliability in tough operations.
The box-section frame is thickened and strengthened to resist torsion and increase durability. Center pins are widely spaced for higher resistance to torsion.
Flat arrangement of the propeller shaft is achieved to reduce resistance at the joint and to increase durability
On the indicators, monitors and alarms, many LEDs are utilized for longer service life resulting in less failure, enhancing the reliability.
The HN bushing containing lubricant is provided at each joint to reduce grease consumption, extend lubrication intervals (100 to 500 hours), and increase durability
Numerous elaborate components are utilized for higher durability and reliability. The proven ORS joints and high-pressure hydraulic lines are utilized in the hydraulic system, and waterproof connectors in the electrical system.
The ample cooling capacity of the hydraulic oil cooler helps reduce oil temperature fluctuation, and extend service life of components.
Notes :
- The photos used in this brochure include optional equipment.
- Some of the pictures in this brochure show an unmanned machine with attachments in an operating position. These were taken for demonstration purposes only and the actions shown are not recommended under normal operating conditions.
Plenty of maintenance expertise always keeps the machine in good conditions for enhanced safety and higher job efficiency.
With the easy-to-read monitor, the operator can see instructions for scheduled servicing and maintenance.
Monitor Indication Items: Service intervals, travel speed, mileage, hour meter
Replacement Alerting: The indicators alert the operator for scheduled replacement intervals to ensure proper maintenance.
Engine oil / filter, fuel filter, hydraulic oil / filter, transmission oil / filter, Axle oil.
The large counterweight is arranged to protect the fuel tank from collisions with obstacles during operation.
The fresh air filter can easily be replaced from the cab, and circulation air filter also replaced by detaching the drink holder.
*Cab model only
Engine oil capacity and filter capacity are increased for longer filter replacement intervals, reducing maintenance time and downtime.
The emergency electric pump delivers the necessary oil pressure for power steering even in the case of an emergency. This allows normal steering at all times even if the engine fails.
The dual-line hydraulic brake system is utilized: even if one line fails, the other can work for braking. The brake is an enclosed wet single-plate type for reliable braking.
The radiator and oil cooler are made of aluminum instead of conventional steel or copper for corrosion prevention.Furthermore, the pararell arrangement of the radiator and oil cooler improves cooling capability and accessibility for maintenance.
- Inclined Ladder
- Retractable Seat Belt (Optional)
Focusing on top-class operator comfort... riding comfort with less vibration and sound, and plenty of operator space... like large-sized models.
The mechanical suspension seat is provided standard to suppress vibration from the machine body for comfortable operation over long hours for ROPS/FOPS cab. The seat can be reclined, and adjusted horizontally to suit operator build for the optimum position. Seat cushion is also adjustable. An air suspension seat, associated with a headrest, lumbar support, seat height adjustment and seat heater, is optionally available for finer adjustments.
A cluster of controls are functionally grouped for ease of operation. The controls, used for prestart setting, are located on the right console to the seat, and those, handled during and after operation are on the front console.
The steering wheel is tiltable and to suit operator of all builds for comfortable operation.
The pilot-controlled lever is optionally available for pleasant fingertip control.
The brake pedal and accelerator pedal are ergonomically positioned for ease of control.
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.
The front curved glass window gives good upward visibility, so the operator can directly see the movement of the bucket for safer loading.
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 bi-level air conditioner allows air conditioning at foot space and overhead simultaneously. Airflow direction can be freely adjusted with airflow volume automatically adjusting according to temperature setting. The pressurized cab shuts out dust and debris even in dusty environment.
The cab rests on fluid-filled elastic mounts to absorb shocks and vibration, and reduce resonance.
The cab is well sealed, and the new lownoise engine is utilized to reduce sound, along with the various noise reduction measures.
The ROPS / FOPS cab is provided to protect the operator from injury in an accident.
