Seafood is known for its high nutritional value, and with the improvement of living standards, seafood has transformed from a luxury item to an ordinary household food. Due to the fact that most seafood is produced in coastal areas, transporting it to inland cities heavily relies on ISUZU Refrigerated Trucks designed specifically for long-distance transportation.

 

Unlike fresh fruits and vegetables, aquatic products have stricter requirements for temperature, humidity, and loading methods. Before loading, the refrigeration compartment must be pre cooled to 0-5 ° C. In addition, the surface of seafood must be thoroughly cleaned to prevent bacterial growth in a closed environment. For the transportation of live seafood, the refrigeration room should maintain a relative humidity of 95% -100% and be equipped with an oxygen supply device, and the temperature should also be adjusted to a suitable range. For deeply frozen products, the temperature during transportation should be maintained between -18 ° C and -20 ° C.

During refrigerated transportation, the evaporator fan may cause the surface of seafood to dry out. To address this issue, adding an appropriate amount of ice can help retain moisture, extend shelf life, and maintain the quality of seafood for up to a month.

 

Another method is to fill the ISUZU Refrigerated Truck with seawater cooled to 0-1 ° C and immerse the seafood directly into it. This method can maintain the quality of seafood for 10-14 days, but seafood may absorb salt and needs to be rinsed before consumption.

 

It should be noted that standard refrigerated trucks are not corrosion-resistant. Long term exposure to seawater can damage refrigerated carriages and refrigeration units. Therefore, after each transportation, the doors must be opened to thoroughly clean and dry the refrigerated truck to prevent corrosion and maintain its functionality.

ISUZU Fire trucks are strategically deployed according to specific disaster scenarios to ensure an efficient emergency response. Two main types of fire trucks are used to rapidly extinguish fires in urban areas. Pump trucks are the basic configuration, connecting directly to fire hydrants or other water sources for emergency firefighting. They can also serve as water supply vehicles to support other firefighting operations. Meanwhile, tank trucks, equipped with independent water reservoirs, offer autonomous firefighting capabilities, which are particularly important in water-scarce environments. In addition to independent use, they often operate in conjunction with fire scenes, serving as both water transport and water supply vehicles.

Different fire scenarios require tailored solutions. Foam trucks are essential equipment for professional urban fire departments. They are specifically designed to extinguish flammable liquid fires, particularly petroleum-based fires, making them indispensable in locations such as petrochemical plants, oil depots, and airports. They utilize the unique physical properties of foam—low density, high fluidity, high heat resistance, and adhesion—to form a rapid sealing layer on burning materials, extinguishing fires through suffocation. High-expansion foam trucks further develop this technology, representing an innovative and efficient, cost-effective approach. It produces a large volume of lightweight, insulating foam with wide coverage, enhancing firefighting effectiveness in enclosed spaces while also assisting with smoke and toxic gas extraction.

CO2 fire trucks are an ideal solution for protecting sensitive environments such as libraries, museums, and precision equipment. Liquid CO2 is non-conductive, non-corrosive, and non-flammable, enabling rapid cooling and oxygen dilution without damaging valuable assets. Similarly, dry powder fire trucks play a key role in fires involving energized equipment and flammable gases. They utilize powdered inorganic salts that decompose under heat to interrupt the combustion chain reaction and form an oxygen barrier coating at high temperatures. They serve as a versatile complement to foam systems and are particularly effective in large-scale industrial fire scenarios, such as chemical pipeline emergencies.

During normal driving, please avoid unnecessary clutch operation. Under typical driving conditions, the clutch of the ISUZU Concrete Mixer Truck should remain fully engaged and should not slip. Do not step on the clutch pedal or place your foot on it, except when starting the vehicle, shifting gears, or braking at low speeds. Long term placement of feet on the clutch pedal can cause the clutch to slip, friction plates to wear out, and in severe cases, even damage the pressure plate, flywheel, or cause the clutch spring to anneal. This type of operation not only increases the risk of mechanical failure, but also leads to increased fuel consumption and rising operating costs.

The correct starting technique should follow the principle of "quick lifting, slow engagement, and smooth connection". When lifting the clutch pedal, quickly lift it first. When the engine sound changes, indicating that the clutch is in a semi engaged state, the lifting speed should be slowed down. Then, gradually release the pedal completely, while smoothly controlling the throttle according to the engine load to ensure a smooth start.

When shifting gears, the clutch should be quickly and decisively pressed and released, and should not be in a semi engaged state for a long time, otherwise it will accelerate wear and tear. Coordination with the accelerator pedal is also crucial. To further ensure smooth gear shifting and minimize wear on the gearbox and clutch, it is recommended to use the "dual clutch shifting method". Although this technique requires more practice, it can improve fuel efficiency and reduce long-term maintenance costs, making it a worthwhile practice for economical and environmentally friendly driving.

ISUZU Road Sweepers are highly suitable for environments with high dust concentrations, such as cement plants, coal mines, mining areas, steel plants, thermal power plants, and ports, due to their efficient dust collection and suppression capabilities. It is equipped with a wide vacuum nozzle and four filter elements in the garbage bin, which can minimize dust emissions to the greatest extent possible. In addition, a water spray nozzle is installed at the rear of the car to effectively spray and wet the road surface.

The main advantage of Isuzu road sweepers lies in their humanized operation. All major functions, such as starting and stopping the auxiliary engine, adjusting fan speed, controlling the suction port, operating the rear door, lifting and lowering the garbage bin, and starting the spray nozzle, can be easily completed through the control panel in the cab. The truck adopts a pure vacuum mode, without the need for reverse blowing, and is equipped with a unique patented filtration system to prevent secondary dust leakage.

Due to the scarcity of rubber vulnerable parts, operating costs can be maintained at a low level; Meanwhile, through multi-stage dust removal methods such as gravity and inertia, the dust removal performance is highly efficient. Its unique dry dust removal mechanism can achieve automatic online and offline cleaning without manual intervention, making it suitable for heavily polluted areas.

This device is designed for all-weather operation and can operate reliably day and night even in cold winter. In addition, the automatic pulse vibration system cleans the filter element every 20-30 seconds, effectively reducing the risk of clogging. The filter element is easy to disassemble and clean, ensuring the continuous and efficient operation of the equipment and convenient maintenance.

 

The weak or slow lifting of a ISUZU Truck with Crane is usually caused by low or no pressure in the hydraulic system. In this situation, the operator should immediately stop the operation and continue only after troubleshooting. The following is a guide for diagnosing and resolving common causes of insufficient hydraulic pressure.

Firstly, check if the hydraulic pump is supplying oil. If the pump does not supply oil, possible reasons include incorrect pump rotation direction, severe wear or damage to internal components, excessive suction resistance due to filter blockage or high oil viscosity, or air leakage in the suction pipeline. In this case, the overflow valve should be disassembled and cleaned, and the spring should be inspected or replaced to restore its normal operation.

Next, check if the entire hydraulic system can establish normal pressure. Insufficient pressure in specific pipelines or hydraulic cylinders may be caused by blockages in pipelines, throttle valves, or directional control valves. To identify the problem, each part should be checked step by step - simultaneously checking pressure and oil flow - to identify and remove any blockages.

In addition, it is necessary to check whether the pressure relief valve is working properly. If the valve in the pressure circuit gets stuck in the return position due to contamination, it may cause a malfunction, allowing the pressure oil to flow directly back to the tank. Other potential causes include loose pipeline connections, severe internal valve leaks, or damaged seals of hydraulic cylinders or motors. To solve these problems, please disassemble and clean the affected valves, check the sealing clearance, and replace any worn or damaged sealing components.

 

To ensure reliable winter operation of ISUZU concrete mixer trucks, specialized maintenance of the chassis and superstructure is crucial.

Chassis Maintenance

Proper chassis maintenance involves multiple systems. First, preheat the engine at standard idle speed to ensure all components are fully lubricated before operation. For the brake system, the air dryer should be inspected or replaced promptly, and condensation in the air tank should be drained regularly to prevent freezing. The cooling system should be filled with long-lasting antifreeze and anti-corrosion coolant, which typically remains ice-free at -20°C. In colder regions, the coolant concentration can be increased, but should not exceed 60% to prevent corrosion. Additionally, the battery electrolyte level should be regularly checked to ensure it is 10-15 mm above the plates and has a specific gravity of at least 1.24 g/cm³. Check the tightness and overall condition of the battery terminals and cable clamps every 500 km.

Superstructure Maintenance

The superstructure also requires attention in cold weather. If the ambient temperature falls below the minimum specified temperature for the hydraulic oil (approximately 10°C), allow the engine to idle for 10-15 minutes with the mixer drum stationary to preheat the hydraulic system. H32 or L-HM32 (NAS Grade 9) hydraulic oil is recommended for use in northern winter conditions. Please note that mixing different brands or grades of hydraulic oil is strictly prohibited. When changing oil grades, thoroughly clean the oil tank and replace or clean the oil filter. Reducers should be maintained with GL-5 gear oil based on the operating environment. After each use in cold conditions, completely drain the oil tank and water supply system lines to prevent freezing damage. Installing an insulation jacket on the mixer drum is recommended during winter operation.

In summary, consistent and thorough maintenance of the chassis and superstructure is key to maintaining vehicle performance and extending service life throughout the winter.
