There is a more recent version of the info about oil sampling available!

Why take oil samples from heavy used machinery?

Analyzing the oils used in construction machinery can be useful to get information about wear from the contents of the used oil. An analysis of the existing oils only makes sense if you have an approximate idea of ​​how long the oil was in use. If the oil has only recently been changed, an analysis of the condition is not very useful. There are then too few analyzable particles in the oil. If the oil used is much older than permitted, i.e. the change intervals have been significantly exceeded, the values ​​will also be incorrect. But if the oil is in a normal change cycle, you can read a lot of information from the trace elements. It is therefore important to know whether the prescribed maintenance intervals on the construction machine have been observed.

How to take an oil sample from heavy used machinery?

For meaningful results, it is necessary to warm up the machine first. Otherwise there will be many particles deposited on the bottom of the oil pan or in the filter. The oil must therefore be vigorously moved and the viscosity increased in order to obtain meaningful results. Then use a very clean container and a pump to remove the oil, e.g. from the engine/the hydraulic circuit or from the gearbox. The extracted oils need to be sent to a certified laboratory. There, the lubricants are analyzed for their ingredients using various methods. It can be used to determine whether there are increased levels of silicon, sulphur, copper, coolant or other trace elements in the oil.

What can I read from the results?

A professional laboratory for the analysis of construction machine oils usually provides us with an interpretation of the analyzed values. Too much silicon means dirt gets into the machine’s systems and you have to look at where and how dirt gets into the system. If coolant is found in the engine oil, there is a problem in the cooling system. If traces of aluminum are found in the transmission oil, one can conclude that there is increased wear in some components. The same applies to the presence of chromium, copper or magnesium.

Mevas offers oil sampling as additional service during inspections. As soon as we have the results of an oil analysis, our technicians will advise you and describe the possible causes. A hint is given on what to do to avoid early problems. Do you have any questions? Feel free to comment below the blog or send us a message.

These are the fundamental assemblies and components of a crawler excavator. The combination of these elements enables the machine to perform a wide range of excavation and construction tasks with precision and efficiency.

What is different between a tracked and a wheel excavator?

A wheel excavator, as the name suggests, differs from a crawler excavator primarily in its mode of mobility. While the basic functions and components are similar, the wheel excavator is mounted on wheels instead of crawler tracks. Here are the key differences between a wheel excavator and a crawler excavator:

1. Mobility:

• Crawler Excavator: It is equipped with crawler tracks that provide excellent stability and traction on uneven or soft terrain. Crawler excavators are often used in rough and challenging terrains, including construction sites, mines, and forestry operations.
• Wheel Excavator: Wheel excavators are mounted on wheels, similar to a typical vehicle. They are more suitable for operating on roads or other solid surfaces. Wheel excavators offer greater speed and mobility on paved or firm ground, making them well-suited for urban construction or roadwork.

1. Undercarriage:

• Crawler Excavator: It has a heavy undercarriage that houses the crawler tracks, rollers, and sprockets, which provide stability and distribute the machine’s weight evenly over a larger surface area.
• Wheel Excavator: The undercarriage of a wheel excavator consists of wheels and tires, which are more similar to those of a truck or a vehicle. This undercarriage is designed for improved road travel.

1. Ground Pressure:

• Crawler Excavator: Crawler excavators have a lower ground pressure due to the larger surface area of their tracks, making them suitable for work in soft or sensitive terrains without causing as much ground damage.
• Wheel Excavator: Wheel excavators typically have a higher ground pressure compared to crawler excavators. This can make them less suitable for soft or sensitive ground conditions.

1. Versatility:

• Crawler Excavator: Crawler excavators are known for their versatility in off-road applications and rough terrains. They can handle a wide range of tasks, from digging and lifting to forestry work.
• Wheel Excavator: Wheel excavators are more specialized for tasks that involve frequent movement between job sites on solid surfaces. They are often used for urban construction, road maintenance, and tasks that require frequent relocation.

1. Speed and Travel:

• Crawler Excavator: While crawler excavators are slower when it comes to road travel, they excel in off-road mobility and stability.
• Wheel Excavator: Wheel excavators can travel at higher speeds on roads and are better suited for tasks that involve longer travel distances between worksites.

In summary, the main difference between a wheel excavator and a crawler excavator is their mobility and undercarriage. Wheel excavators are designed for jobs that require frequent movement on roads and solid surfaces, while crawler excavators excel in off-road applications and challenging terrains. The choice between the two types of excavators depends on the specific job requirements and operating conditions.

There are different types of inspections for used Caterpillar machines. There is the TA1-level for a standard inspection and the TA2-level for inspections with more in-depth investigations.

In line with the needs of our customers, we generally offer inspections at the TA1+ level. Can you imagine what that means? It is a visual inspection that includes a performance test and a functional test. Engines, gearboxes and torques are tested by running the machine. Tyres or Undercarriage are measured and estimated for remaining life. A detailed inspection checklist is prepared and photo documentation is taken. The so-called Product Status Report PSR is downloaded from the ECMs. And we look out for weak points on the equipment. If you have questions afterwards, we are there for you and answer them quickly.

Is a CAT TA-1 inspection sufficient?

For larger machines, a TA1 inspection is often not sufficient. Machines have a service life that far exceeds that of a standard earthmover. For these machines we offer an extended inspection service similar to TA2 on request. Our engineers do filter cutting, oil sampling, opening the final drives and take cycle times. We know the required specifications for CAT-equipment. For midsize and smaller machinery a TA-1 Plus is the best solution.

By the way, the level of a CAT-TA inspection applies as well for all other brands such as Liebherr, Komatsu, Hitachi or Volvo CE. If you are looking for used heavy machinery try a search here.

What operational testing should a detailed inspection for a used heavy machine include?

A detailed inspection for a used heavy machine should include various operational tests to assess the machine’s performance, safety, and overall condition. These tests help identify any potential issues, defects, or areas that require maintenance or repair. Here are some key operational tests that should be part of the inspection:

1. Engine Performance Test:

• Start the machine and observe the engine’s startup, idle, and shutdown procedures.
• Check for abnormal noises, vibrations, or smoke emissions.
• Test engine throttle response and acceleration.
• Evaluate the machine’s ability to maintain a consistent RPM (revolutions per minute) under different loads.

1. Hydraulic System Test:

• Test the hydraulic functions, such as lifting, lowering, and tilting (for equipment like excavators and loaders).
• Check for hydraulic leaks or abnormal fluid levels.
• Assess the responsiveness and smoothness of hydraulic controls.

1. Transmission and Drive System Test:

• Test the forward and reverse gears (if applicable).
• Evaluate the functionality of the transmission, including smooth shifting and proper engagement.
• Inspect the performance of the differential and drive axles.

1. Brake and Steering System Test:

• Check the braking system for responsiveness and effectiveness.
• Test the parking brake and ensure it holds the machine securely.
• Assess the steering system for smooth operation and proper alignment.

1. Electrical System Test:

• Check the operation of all electrical components, including lights, indicators, gauges, and warning systems.
• Test the battery, alternator, and starter to ensure proper charging and cranking.

1. Attachments and Accessories Test:

• If the machine has attachments or accessories (e.g., buckets, forks, blades), test their functionality and alignment.
• Check for wear and tear on the attachment points and pins.

1. Operational Efficiency Test:

• Evaluate the machine’s overall efficiency in performing its intended tasks. This can include lifting capacity, digging power, or other relevant factors based on the machine’s type and purpose.

1. Safety Systems Test:

• Test safety features such as seatbelts, rollover protection systems (ROPS), and other safety interlocks.
• Ensure that warning signals and indicators work properly.

1. Noise and Vibration Assessment:

• Listen for unusual noises during operation that may indicate mechanical issues.
• Assess the level of vibration and its impact on the operator and machine components.

1. Load and Performance Tests:
   • For specific heavy machinery, conduct load tests to assess their performance under load conditions.
   • Check for stability, tipping, or structural issues when handling loads.
2. Functional Test of Special Features:
   • If the machine has specialized features (e.g., GPS systems, advanced control systems), ensure they function as intended.
3. Safety Inspections:
   • Verify that safety guards, shields, and other safety features are in place and functional.
   • Ensure all emergency shut-off systems are operational.

A detailed inspection may also involve using diagnostic tools and equipment to assess the machine’s performance and condition more accurately. It’s important to document the results of these operational tests in a comprehensive inspection report, which can help potential buyers or users make informed decisions about the machine’s purchase or use. Additionally, consulting the manufacturer’s guidelines and specifications for the specific machine being inspected is advisable to ensure that all relevant tests are performed.

What means biosecurity inspection for machinery entering Australia?

Australia’s import regulations for used machinery are the strictest in the world in terms of the cleanliness of the machinery. If used machines are not clean enough to be allowed into Australia, they must be re-exported to Singapore. There they will be cleaned at the buyer’s expense.

Who can do pre-shipping inspections or cleanliness inspections?

Mevas offers AQIS quarantine checks for used heavy machinery before delivery to avoid this. This service we only offer in Germany and sometimes in ports in Belgium or the Netherlands. Last year, for example, we inspected a Hitachi EX1200 for a customer. If you want to know more about this, feel free to ask your question in the comments below. Or give us a call. We are happy to share our experiences.

What rules exist for biosecurity cleaning for Australia?

Biosecurity inspection for machinery entering Australia refers to a set of procedures and checks implemented by the Australian government to prevent the introduction and spread of pests, diseases, and contaminants that could harm the country’s agriculture, environment, and public health. These inspections are crucial to safeguard Australia’s unique ecosystems and protect its agricultural industry from potentially devastating threats.

Key points regarding biosecurity inspection for machinery entering Australia include:

1. Risk Assessment: Machinery that enters Australia is assessed for its potential to carry or introduce biosecurity risks. This assessment takes into account factors such as the machinery’s origin, history of use, and any potential contaminants it may carry.
2. Cleaning and Treatment Requirements: Many types of machinery, equipment, and vehicles must undergo thorough cleaning and treatment to remove soil, plant material, and other contaminants before entering Australia. This is to ensure that they do not introduce pests and diseases into the country.
3. Import Permits: Depending on the type of machinery, an import permit may be required. Permits are issued by the Australian Department of Agriculture, Water, and the Environment and outline specific conditions and requirements that must be met.
4. Inspection at the Border: Machinery entering Australia is subject to inspection at the border. This inspection is carried out by biosecurity officers who check the machinery for signs of contamination and conduct further examinations as necessary.
5. Quarantine Facilities: In some cases, machinery may be directed to quarantine facilities for further inspection, cleaning, or treatment. This is especially true if the machinery is found to be heavily contaminated or poses a higher risk.
6. Biosecurity Charges: Importers are typically responsible for the costs associated with biosecurity inspection and any necessary cleaning or treatment. These charges can vary depending on the type of machinery and the extent of the inspection and treatment required.
7. Regulations and Compliance: It is essential for importers to be familiar with and comply with Australian biosecurity regulations and guidelines to ensure a smooth entry process for their machinery.

The goal of biosecurity inspection for machinery entering Australia is to maintain the country’s biosecurity and protect its agriculture, environment, and public health. Australia has stringent biosecurity measures in place to mitigate the risk of introducing invasive species, pests, and diseases that could have detrimental effects on its ecosystems and industries.
