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.

A Complete Guide for Engineers, Product Developers, and International Buyers

Manufacturers today have access to more fabrication processes than ever before. Among them, metal stamping and CNC machining are two of the most widely used methods for producing precision metal components across the electronics, automotive, lighting, telecommunications, and industrial sectors.

However, choosing the right process is not always straightforward. Each method has its strengths, limitations, and ideal application scenarios. Selecting the wrong process can lead to unnecessary costs, long lead times, quality issues, or performance failures.

This guide explains the key differences between metal stamping and CNC machining and helps you determine which process is best for your part — based on geometry, volume, tolerance, material, and cost requirements.

1. What Is Metal Stamping?

We won't go into detail about what metal stamping is here; we can find more information in our previous articles (Manufacturing Metal Stamping). We know that metal stamping processes transform metal sheets into precision parts through the following operations:

• Blanking
• Punching
• Bending
• Deep drawing
• Coining
• Embossing

Metal stamping is ideal for high-volume production, especially when parts require consistent shapes, thin profiles, and repetitive geometries.

2.What Is CNC Machining?

CNC machining offers unmatched flexibility since no dedicated stamping dies are needed.

3.Cost Comparison: Stamping vs CNC Machining

4.Precision & Tolerance: What Engineers Should Know

If your design requires extremely tight tolerance across multiple planes, machining is likely the better fit.

5.Material Considerations

Because machining removes material rather than forming it, material ductility is less critical.

6.Part Geometry: The Most Important Factor

If the part requires material removal and multi-directional shaping, choose CNC.

7.Production Speed & Lead Time

Production time depends on cycle time per part

Suitable for urgent or small batch orders

8.Quality Consistency & Scalability

9.Environmental & Waste Considerations

10.Which Process Should You Choose?

* In many real projects, both processes are combined, for example, stamping the outer geometry and machining critical features.

11.Why Many Overseas Buyers Choose Metal Stamping Partners in China

Custom OEM/ODM support for global clients

Both metal stamping and CNC machining are powerful and reliable manufacturing processes. The right choice depends on your part’s geometry, tolerance, material, budget, and production volume.

If you need high-volume, thin, and repeatable metal parts, stamping is almost always the better choice.
If your parts require complex 3D geometry or extremely tight tolerances, CNC machining is more suitable.
A professional supplier can help evaluate your drawings, material selection, tolerance requirements, and cost targets to recommend the optimal process or a combination of both.
