Hitachi ZW220 is a universal forklift from a Japanese manufacturer. This model will satisfy professional users, as it has high potential. The enormous capabilities of this loader are confirmed by numerous factory tests and positive user reviews, which, in fact, are facilitated by high productivity and excellent workmanship. The machine is made from Japanese-made components from Hitachi, and is designed for a wide range of work. This article presents the main capabilities of this device, characteristics and operating features.
Purpose
Hitachi ZW220 is a front-end loader for work in the construction and agricultural sectors. The machine can also act as a means for housing and communal needs. For example, using this loader you can clean up any type of debris, including leaves, sand and even snow, as well as other bulk materials. If necessary, the model in question is capable of performing earth-moving operations, mowing grass and leveling gravel surfaces. With the necessary equipment, the machine can be “turned” into a forklift or a universal bulldozer. In construction, this machine is suitable for road installation or pothole repair. Special utility accessories will make the Hitachi ZW220 an indispensable snowblower, as well as a tool for cleaning, loading and transportation.
Attachments
- Snow plow is a mechanically driven device as standard. This product provides quick and effective removal of snowdrifts. But of course, the hydraulic version is much faster. In this case, you do not need to leave the cab to adjust the angle of the blade, because the hydraulic drive can be controlled by a lever directly from the operator’s cab.
- Pallet forks are attachments for loading and transporting goods placed on pallets. In particular, these are predominantly fragile and easily breakable goods, such as glass containers. You can load and unload any similar cargo that is located on pallets. With this attachment option, the front loader essentially takes on the capabilities of a forklift.
- Telescopic boom is an attachment for moving cargo containers in the air. The maximum load capacity can reach two tons, and depends strictly on the modification. The boom is equipped with a crane hook, which is fixed on a special hinged support, which allows the hook to rotate in different planes.
- A log grabber is a device for working primarily with cylindrical objects - logs, piles, pipes and poles. Please note that the design of the log grabber is reinforced with innovative hydraulic hoses using modern production technology. This component ensures stable and uninterrupted operation of the log grabber even under heavy loads and high pressure in the hydraulic system.
- A blade is a device that is very convenient in cases where there is no specialized bulldozer available. After all, this option performs almost the same functions, and in addition, it is also equipped with a rotating function, which makes it possible to adjust the angle of rotation of the blade relative to the front axle of the machine. In this way, you can adjust the direction of the thrown sand, snow or soil. In particular, the modes “forward”, “left” and “right” are provided.
- The jaw bucket is an attachment with high potential. Its wide functionality lies in a special design consisting of two working “blades” (or jaws) that interlock with each other. Thus, a grip is formed on the cargo container so that it does not fall out during transportation. This is very convenient and effective, especially if there are special teeth on the edges of the jaws that provide a more secure grip.
- A brush is a utility device that is useful in housing and communal services. For example, you can use it to remove loose and freshly fallen snow with a fly, or sweep away dust, leaves, soil and any other loose debris. To prevent debris from being sprayed during the cleaning process and accumulated in one pile, the brush can be equipped with a special humidifier. In this case we are talking about a “road” type brush. There are also rotary brushes and industrial brushes with a hopper.
- Forks with a clamp/grab are a convenient device for loading and transporting hay and straw. It is used for working primarily with fibrous materials, including mown grass, loosened haylage, etc. Please note that the density of the material can reach 800 kg per 1 cubic meter. m. Perhaps, replaceable agricultural forks are the most convenient and rational equipment for these needs.
- A cradle is an attachment that can replace a crane to perform various operations at height. It is a lifting platform into which the operator enters and then rises to a certain height. Further, the following actions are available for execution: installation and laying of high-voltage wires and lighting shades, finishing of building facades, painting of ceilings and other operations carried out at height - both inside and outside buildings and premises. The wide entrance opening provides convenient access to the inside of the platform.
- The bucket adapter is an additional accessory for more secure attachment of attachments that are designed for higher lifting capacities. For example, using an adapter you can connect a bucket capable of lifting more than 3 tons of load.
- The bucket blade is a convenient device that is attached to the bucket. Supplied as an auxiliary product for removing difficult to shovel snowdrifts along with ice. Thus, a bucket along with a knife is a more effective way to remove snow.
Safety of HITACHI ZW 220 wheel loaders
To ensure the highest level of safety when working with ZW 220 wheel loaders, HITACHI has offered the following:
- The presence of a protective mesh on the cooling fan.
- Full compliance of the cabin with established standards for protecting people from falling objects and overturning of special equipment.
- The dual-circuit brake system ensures that the equipment stops exactly when the driver needs it.
- convenient inclined ladder for access to the cabin.
- Availability of seat belts.
- Protection system against incorrect starting of the power unit.
- Possibility to install an additional emergency loader control system.
Features of the device and operation
- The Hitachi ZW310 is a forklift with a powerful off-road chassis, thanks to which you can overcome various terrain without fear of damage to the bottom and components of the loader. In particular, let's pay attention to wide-profile wheels designed for movement on ruts, snowdrifts and high-altitude climbs. The deep tread prevents slipping and slipping on slippery, icy surfaces or muddy roads. In addition, the protector is equipped with a self-cleaning function from dirt. Thanks to this, the wheels will have to be cleaned much less often than those of competing machines. These tires are included as standard and do not have to be replaced with an expensive wheeled or tracked chassis. Of course, to improve cross-country ability, the car has all-wheel drive for all wheels, and also has increased ground clearance, high approach and departure angles, and minimal body overhangs.
- Despite its impressive appearance, the model in question is actually relatively compact and maneuverable, as far as possible for this class of loaders. The relatively small turning radius and small wheelbase make it possible to make a turn in the most problematic areas, in cramped conditions or in the presence of obstacles that need to be avoided.
- The Hitachi ZW220 front-end loader fully reveals the potential of working components and assemblies, including moving parts and attachments. This also applies to the hydraulic system. Thus, a powerful power plant with an output of 220 horsepower is responsible for unlocking the potential. It is turbocharged and exhibits excellent traction characteristics. Thus, the rotation speed is 2000 rpm, and the maximum speed when driving around the city can reach 36 km/h. In addition, we note the high strength of the internal combustion engine components, as well as the presence of auxiliary functions that ensure uninterrupted and reliable operation during multi-shift operation. We are talking about a liquid cooling system, as well as a preheater. Both components are the prerogative of the basic configuration, and are designed to avoid problems with starting and operating the engine in conditions of extremely low and hot temperatures. The engine fully meets modern environmental requirements, despite the fact that the machine went into production quite a long time ago. Finally, we note the high fuel efficiency and spacious fuel tank. In addition, the engine is undemanding in terms of fuel quality, as it is equipped with fuel filters.
- The equipment is designed for high load capacity due to its considerable total weight. At the same time, in this way it was possible not only to increase the mass of the lifted loads, but also to improve the throughput of the hydraulic system pump. The capacity of the working body included in the basic equipment has also been increased compared to its predecessor.
- The operator's cabin of the Hitachi ZW220 forklift is distinguished by its thoughtfulness, convenience and increased spaciousness. In particular, in this cabin, users are attracted by the wide glass area with almost 360-degree visibility, the ability to customize the driver's seat and steering column, as well as pleasant-to-touch finishing materials and a large number of functions. In this case, we are talking not only about ergonomic buttons, levers and switches, but also control and measuring instruments, with the help of which you can monitor the condition of all important systems, devices, working units and assemblies, and troubleshoot any problems in a timely manner. Of course, this will prevent more serious and expensive problems in the future, such as major repairs of the cylinder-piston group (for example). Also worthy of special attention is good and well-thought-out sound insulation, thanks to which the cabin is relatively quiet and comfortable. The driver is not distracted from work, gets less tired and is able to work the entire working day without any signs of fatigue. In fact, this has become one of the ways to increase labor productivity.
- The engine compartment of the Hitachi ZW220 forklift is distinguished by a rational arrangement of components and assemblies, air and fuel filters, refueling containers and other consumables. The hood cover in the raised position is fixed by supports with gas-filled shock absorbers, which is very convenient during long-term repairs. All “consumables” can be replaced quickly enough, and this can be done right on the work site; fortunately, the delivery package includes a basic set of tools located in a special niche.
A range of solutions to improve the productivity of the ZW 220 wheel loaders
To achieve the highest level of performance from the ZW 220 wheel loaders, Hitachi has proposed the following:
- Three operating modes: reduced, normal and increased power.
- Three modes of movement of equipment. “L” - activated in second gear, designed to travel long distances on relatively flat surfaces, without serious elevation changes. “N” - intended for movement during work, for example, when moving loads in a bucket, loading and unloading processes. “H” - similar to the previous option, but allows you to automatically downshift without human intervention.
- The use of technology that ensures smoother operation of the gearbox in automatic mode.
- Power unit with increased torque when operating at reduced power.
- A system that combines operations - the bucket can be used even while moving equipment.
- New hydraulic equipment that allows you to perform simultaneous actions with both the bucket and the boom.
- Three options for automatic clutch release for greater optimization of the work process.
Additionally, the manufacturing company has integrated a number of systems into its special equipment, which are also designed to increase the performance of loaders:
- Control over the position of the boom when moving equipment on uneven surfaces.
- Automatically aligns the bucket parallel to the surface after unloading.
- Automatic alignment of the boom to a certain height.
- A system for leveling the progress of equipment when moving over uneven areas of land.
- Reduced shock loads by installing a special safety valve.
