Machines d’occasion à Shanghai

Shanghai est connue pour avoir beaucoup de machines de construction intéressantes comme des pelles, des chargeuses sur pneus, des compacteurs, des niveleuses et d’autres machines pour la construction de routes. Cependant, en Chine, il ne faut pas faire confiance aux vendeurs sans vérifier, car il est courant que les machines soient repeintes et changées d’étiquette, ce qui rend difficile de connaître le vrai pays d’origine. Cela peut être une mauvaise surprise pour les acheteurs si la machine arrive dans un autre pays et que les pièces de rechange ne sont pas disponibles. Pour éviter cela, il est fortement recommandé de faire inspecter les machines de construction d’occasion en Chine avant l’expédition. Il est aussi important de ne pas faire d’acompte avant d’être sûr de l’état et du pays d’origine de la machine.

Ce que comprend notre inspection en Chine

Notre service en Chine comprend une inspection visuelle de la machine avec un test de fonctionnement, réalisé par le conducteur du vendeur. Notre inspecteur prend des photos et des vidéos et vérifie l’état général et l’usure de la machine, y compris les numéros de série et le moteur. Il recherche aussi des fuites ou des fissures sur le châssis, vérifie les accessoires et les pneus, et évalue la fiabilité du vendeur. Ce n’est peut-être pas une inspection technique complète, mais cela peut vous aider à éviter les plus grosses erreurs lors de l’achat d’une machine en Chine. Nous avons déjà eu de mauvaises surprises à Shanghai et dans les environs, et certains de nos clients ont perdu beaucoup d’argent. Certains ont même reçu une machine différente de celle qu’ils avaient inspectée. C’est pourquoi nous recommandons fortement une deuxième inspection au port avant l’expédition pour être sûr de ce que vous achetez. Nous inspectons toutes les marques comme Caterpillar, Tadano, Komatsu ou Doosan.

Contrôle du chargement au port de Shanghai

Si vous souhaitez un service supplémentaire de contrôle du chargement au port de Shanghai, cela est aussi possible. Vous devez communiquer avec le vendeur et les autorités pour donner l’accès au port à notre inspecteur. Pour un contrôle du chargement, les frais sont de 800 euros (820 USD) pour une journée de service.

Nos conseils en matière de sécurité

• Vérifiez les numéros de série auprès du fabricant
• Demandez à recevoir de nombreuses photos détaillées
• Vérifiez la localisation du vendeur sur Maps
• Faites inspecter les machines par des personnes indépendantes
• Vérifiez le numéro de série de la machine avant le chargement au port

How to Check the DPF Status of a Used Construction Machine

Before purchasing a used construction machine, it’s critical to check the status of its Diesel Particulate Filter (DPF). This filter plays a key role in meeting modern emissions regulations and avoiding costly repairs. In this newsletter, we explain what a DPF is, why it matters, how to check its condition, and how to spot illegal modifications.

What Is a DPF in a Construction Machine?

A Diesel Particulate Filter (DPF) is a component in the exhaust system that traps and removes soot (particulate matter) from the engine’s exhaust gases. It helps the machine meet emission standards such as Tier 4, Stage IV, and Stage V. A DPF reduces black smoke and harmful particles like PM10 and PM2.5, making the machine cleaner and more environmentally compliant.

Why You Should Check the DPF Before Purchase

Replacing a DPF in a large machine can be extremely expensive. For a mid-size machine like a 20–30 ton excavator, costs range from $5,000 to $10,000. For larger equipment such as a 40+ ton excavator, dozer, or loader, DPF replacement can exceed $25,000. These high costs make it essential to evaluate the DPF before finalizing any purchase.

How to Check the DPF Status

1. Check the Machine’s Display or Diagnostic Menu
   Most modern machines from brands like Caterpillar, Komatsu, Volvo, Hitachi, and John Deere feature onboard monitoring systems. You can access information such as the DPF soot level, regeneration status, and any fault codes by navigating through the operator’s display or service menu.

• Use a Diagnostic Tool
  Use an OEM or compatible diagnostic tool to retrieve detailed DPF data.
• Caterpillar: CAT ET
• Volvo CE: VCADS or Tech Tool
• Komatsu: Diagmaster
• John Deere: Service ADVISOR

These tools help you check soot and ash levels, regen history, differential pressure, and error codes.

3. Inspect Maintenance Records
    Ask for documentation of the DPF’s maintenance history. Look for the date of the last cleaning or replacement, regen frequency, and any past DPF-related errors. Machines that require frequent forced regenerations may have underlying issues.
   
   
4. Conduct a Physical Inspection
    Check for signs of soot buildup around the exhaust. Listen for active regeneration (higher idle RPM or hotter exhaust). Examine whether any emissions components have been removed or tampered with.
   
   
5. Watch for Warning Signs
    Be alert to frequent or failed regenerations, loss of power, poor fuel efficiency, engine warning lights, and error codes such as P2463 or P2002. These signs may indicate a clogged or malfunctioning DPF.

Pro Tip:
Before replacing a DPF, confirm it is actually at the end of its life. In many cases, a forced regeneration or professional cleaning can resolve the issue for far less money.

Cleaning DPF Instead of Replacing

If the DPF is still structurally sound, you can clean it instead of replacing it. Cleaning (ash removal) typically costs between $600 and $1,500 depending on size and method. Most filters can be cleaned multiple times, with service intervals ranging from 2,000 to 4,500 operating hours.

How to Detect an Illegally Removed DPF

1. Visual Inspection
   Look for welding marks or cuts on the DPF casing. Check that all DPF sensors and wiring are present and intact. Missing or damaged sensors may signal tampering.
   Examine the engine control software if possible. Unauthorized software modifications may hide the fact that the DPF has been removed.
   
   
2. Warning Lights and Error Codes
   A DPF warning light may indicate the system isn’t functioning properly. Read the ECU for stored error codes related to the DPF or its sensors. These codes can offer clues about illegal removal or system failures.
   
   
3. Emissions Testing
   Roadside or formal emissions testing can detect high particulate emissions caused by a missing or faulty DPF. Machines without functioning filters are likely to fail.

Is It Illegal to Remove the DPF fom a heavy machine?

Yes. In most regions, removing the DPF from a construction machine violates emissions regulations. Authorities may issue fines, penalties, or impound the machine. Operating a tampered machine also poses a risk for the buyer if discovered during inspections or audits.

Which emission status can a construction machine reach with a DPF exhaust filter system?

A construction machine equipped with a DPF (Diesel Particulate Filter) can typically meet the following emission standards, depending on the full exhaust aftertreatment system it is paired with:

A construction machine with a DPF can meet:

• Stage IIIB or Tier 4i when paired with EGR/DOC
• Tier 4 Final or Stage IV when paired with SCR and DOC
• Stage V (EU) only when DPF is combined with DOC, SCR, and sometimes ASC

Let Mevas Inspect the Machine for You

When Mevas Heavy Equipment Inspectors evaluate a used construction machine, they inspect the exhaust system and check for DPF-related error messages. Our inspectors identify signs of modification or tampering and include these findings in the final report. This inspection offers peace of mind and costs significantly less than replacing a faulty DPF system.

Before you import or purchase a machine, let Mevas help you avoid costly surprises.

Who Can Perform Large-Scale Valuations of Mining Equipment?

You can see a video about valuation of mining machinery here.

Mevas – A Specialist in Mining Equipment Valuation

While numerous firms offer asset valuation services, only a select few are truly specialised in the appraisal of mining equipment. These specialist firms possess deep knowledge of the mining sector, understand market dynamics, and are familiar with the technical nuances of various types of mining machinery. However, only a handful have the necessary expertise and are prepared to conduct on-site inspections worldwide. Mevas is one such firm, focusing specifically on inspections and valuations for the mining industry.

Consultancies with Mining Expertise

Many general consulting firms include mining-related services, including equipment valuation, within their broader portfolio. While this breadth can be helpful in complex scenarios, these firms may lack the specific expertise needed for accurately assessing heavy mining machinery. Unlike such firms, Mevas positions itself primarily as an inspection business rather than a general consultancy. To date, the Mevas team has successfully completed numerous large-scale valuation projects.

Independent Appraisers and Technical Experts

There are also independent appraisers with relevant qualifications and extensive experience in the mining industry. These individuals often bring strong technical expertise to the table. Wolfgang Bühn, for instance, has been working as a mining equipment appraiser since 2006. Together with his team, he has successfully carried out many substantial inspection and valuation projects, often involving large fleets of machines.

---

Specialist Knowledge for Complex Equipment

While many appraisers may be competent in valuing standard excavators or a small number of dump trucks, more complex equipment often presents a challenge. Assets such as conveyor systems, crushers, screening plants, and stationary processing technology demand a much higher level of technical understanding. This is where Mevas excels.

The Mevas team regularly inspects and values a wide range of machinery used in open-cast mining and quarrying, including:

• Stationary and mobile crushing plants
• Mining Shovels and Trucks
• Conveyor belt systems
• Gravel washing facilities
• Heavy transport machinery
• Workshop and support facilities
• Light vehicles and remaining inventories

How Is Depreciation Calculated for Mining Equipment?

Depreciation in Mining Operations
Depreciation represents the decline in value of buildings and equipment over time due to wear and tear. In the mining sector, companies typically use either the prime cost (straight-line) or diminishing value method to calculate depreciation.

• The prime cost method allows for equal deductions each year over the asset’s effective life.
• The diminishing value method applies a fixed percentage to the remaining balance, resulting in higher deductions in the earlier years.

However, depreciation is not solely about accounting. Real-world asset values are also influenced by:

• Total operating hours
• Usage patterns (e.g., single vs triple shift operation)
• Replacement value of an equivalent machine
• Possible selling price of an equivalent machine
• Component replacement history (e.g., engines, transmissions, axles)
• Transport costs for equipment from the seller to the mine
• Repair work required at short notice to keep operations running

Such factors must be carefully considered to accurately determine the residual value of mining machinery.

---

What Types of Valuation Are Common in the Mining Industry?

Three principal approaches to valuation are used in the mining sector:

1. Depreciated Value
   This method follows the declining balance formula, calculating depreciation over time for accounting purposes. As machinery ages, the rate of depreciation reduces accordingly.
2. Replacement Value
   This approach estimates the cost of acquiring a comparable machine of similar age and usage. It is especially relevant in transactions involving entire operations or in insurance settlements.
3. Fair Market Value
   This valuation is used as a negotiation basis when transferring ownership of mining concessions. It considers transport costs and logistical implications, especially if the incoming operator must procure new equipment while the outgoing one must decommission and remove theirs.

---

For any type of mining equipment valuation, whether underground or above ground, it is important to know the purpose of the valuation. What is the objective and who are the negotiating partners? Please contact us if you have any questions on this topic. We will be happy to advise you and explain which options are best suited to your project.

On-site or On-screen valuation

Depending on your requirements, we will decide together with you whether an on-site inspection of the equipment is necessary or whether an assessment can be made based on the data and images you provide. For purely accounting purposes, an on-screen valuation is often sufficient to calculate the residual values. However, when it comes to complex projects such as the sale of a company or takeover by a new concessionaire, an on-site inspection is usually necessary.

Your Guide to Buying Used Material Handlers for Scrap Handling

Purchasing used construction machinery, especially material handlers for scrap handling, can be a smart financial move. However, ensuring you get a machine that’s reliable, efficient, and cost-effective requires careful inspection and consideration. A well-maintained used machine can serve your business for years, while a poor purchase could lead to frequent breakdowns and costly repairs. Here are some key factors to keep in mind when evaluating a used material handler. First thing for inspection: You will need a reasonable checklist for material handler inspection.

Check the Service and Maintenance History

A machine’s service history is one of the most telling indicators of its condition. Well-documented maintenance records show that the previous owner cared for the machine, followed scheduled services, and addressed any issues promptly. Look for records detailing regular oil changes, hydraulic system maintenance, and any major repairs or replacements. A lack of service history could indicate neglect, which may lead to hidden problems down the line.

Assess the Structural Integrity

Material handlers operate in tough environments, often handling heavy and irregular loads. Inspect the structural components carefully—particularly the boom, stick, and undercarriage—for signs of excessive wear, cracks, or welding repairs. Pay special attention to pin and bushing wear, as excessive play in these areas can indicate structural weakness and the need for costly repairs. Contact us for more info.

Examine the Hydraulic System

The hydraulic system is the heart of a material handler, enabling smooth operation and precise control. Look for leaks in the hoses, cylinders, and pump connections. Check the hydraulic fluid for contamination—milky or discoloured fluid may suggest internal issues, such as water infiltration or metal shavings from component wear. A test run should reveal whether the hydraulics operate smoothly without jerky movements or delays. Experienced inspection companies can run a so-called Oil Sampling with a certified lab to examine the containments for unusual wear in components.

Evaluate the Engine Condition

A well-functioning engine is critical for performance and efficiency. Start the machine and listen for any irregular noises such as knocking, excessive rattling, or hissing sounds. Watch for excessive smoke, which can indicate fuel system problems or worn engine components. Low power output or slow acceleration can be warning signs of deeper issues. Additionally, check for any oil or fuel traces in coolant and for coolant in oil. A too high oil level in engine sump can be a hint for problems.

Inspect the Tires or Tracks

The undercarriage is often one of the most expensive components to repair on heavy machinery. If the machine has tracks, look for wear on the sprockets, rollers, and track links. If it has tires, ensure they have sufficient tread depth and no major damage.

Test the Electrical and Control Systems

Test the electrical system to ensure that all lights, gauges, and switches are working properly. Any flickering displays or non-responsive controls may signal wiring or sensor malfunctions, which can be expensive to diagnose and fix. If a generator is fitted it should be checked for functionality.

Consider the Attachments and Accessories

Many material handlers come with specialized attachments, such as grapples, magnets, or shears. Ensure that any included attachments are compatible with the machine and in good working condition. Hydraulic quick couplers should operate smoothly, and hoses should be free from leaks or excessive damage. It is always recommended to check a material handler with the tool attached.

Run a Test Operation

Whenever possible, operate the machine under real working conditions. Test the boom and stick movements, rotation, and lifting capacity. The controls should be responsive, with no delays or hesitations. Pay attention to unusual vibrations or noises, as these could indicate hidden mechanical issues. Do not forget to check the hydraulic cab raiser and try several full 360° swing operations including the swing brake test. Last but not least: Measure the play in the swing bearing with appropriate tools.

Final Thoughts

Buying a used material handler for scrap handling can be a cost-effective solution if approached with diligence. A thorough inspection and careful evaluation of the machine’s condition, combined with verifying its service history and legal documentation, can help you make a smart investment. If you’re unsure about any aspect of the inspection, consider working with a professional machinery inspection service such as MEVAS to ensure you get the best value for your money. Consider investing some money in a professional inspection to avoid buying a machine with hidden problems.

Reduce replacing cost for undercarriage components

Listen to this article

When it comes to maintaining tracked construction machinery like excavators and bulldozers, the undercarriage is one of the most expensive and essential components. A well-maintained undercarriage not only ensures smooth operations but also significantly reduces costly downtime and repairs. In this newsletter, we delve into critical issues, from track adjustment failures to choosing the right track shoes and measuring undercarriage wear.

The Hidden Costs of Incorrect Track Adjustment

Improperly adjusted tracks are a common issue in tracked excavators, track-loaders and bulldozers, often overlooked by operators. Tracks that are too tight accelerate wear on bushings, sprockets, idlers, and even the bearings in final drives. This can lead to premature failure of components, despite other parts, like rollers and track links, still being in good condition.

For excavators in the 15–30-ton range, track sag is critical and should generally be set between 3-5 inches (7-10 cm). A track chain that is too tight not only shortens component life but also risks cracking bushings. Too lose chains can to jump over the idler centre rim or the sprocket during drive operation. On uneven ground track rollers are no longer guiding the chain in line.

Tip: Always refer to your machine’s manual for specific guidelines or consult your local dealer for advice.

Corrosion and Seized Track Links: A Costly Problem

A significant issue seen in hydraulic excavators is the seizing of track links due to water—especially saltwater—penetration. Damaged seals allow water to corrode internal components, locking bushings and pins in place. Attempts to restore mobility with oil or grease are rarely successful, as the damage is inside the pins and bushings, not the visible chain links.

For minor issues, riding the machine on hard surfaces may restore some mobility. However, in severe cases, replacement of the chain is unavoidable.

Finding the Right Track Shoe Width: Striking the Balance

Choosing the correct track shoe width is a balancing act. Narrow track shoes provide sometimes better traction but may cause the machine to sink into soft ground. Narrower machines are easier to transport. On the other hand, extra-wide track shoes (LGP) distribute ground pressure more evenly but introduce increased torsion forces on drive components when operating on uneven terrain, leading to faster wear.

For every application, it’s essential to select the track shoe width that minimizes both wear and operational inefficiencies. Consult an expert or dealer to determine the best fit for your machine’s typical working environment.

Precision Measurement: Know Your Undercarriage’s Remaining Life

The undercarriage accounts for a substantial portion of a machine’s value—take the Caterpillar D8T, for example, where the undercarriage value can reach €25,000. Misjudging the remaining life by even 30% can result in a financial loss of €7,500.

Proper measurement ensures accuracy. MEVAS-trained inspectors recommend using tools like:

• Track Gauges: To ensure the correct track spacing.
• Ultrasonic Gauges: For measuring track link and bushing thickness.
• Track Roller Callipers: To assess roller diameter and wear.
• Shoe Height Gauges: To check track shoe condition.
  By using these tools, operators can determine wear levels and predict replacement timelines accurately.

Avoiding Roller Sequence Errors

In Caterpillar or Komatsu XL bulldozers, proper track roller sequencing is crucial. These machines typically use a mix of single and double flange rollers, but inexperienced fitters sometimes install rollers in the wrong sequence—or worse, entirely single-flange rollers. Such errors can compromise performance and accelerate wear. Always cross-check roller configurations with manufacturer specifications.

Key Inspection Points for Used Machines

When inspecting a used bulldozer or excavator, pay special attention to:

• Undercarriage Components: Measure track shoes, sprockets, track links, bushings, and idlers.
• Equalizer Bar and Bearings: This component connects undercarriage frames and facilitates horizontal movement. Any excessive play in joints and pivots can indicate expensive repairs ahead.

Thorough inspections can save thousands in repair costs. If you’re unsure about measurements or need a detailed guide, MEVAS offers step-by-step instructions and video tutorials.

Maintaining Undercarriage Health: Best Practices

1. Monitor Track Tension Regularly: Adjust sag based on manufacturer recommendations.
2. Choose Track Shoes Wisely: Match the width to the terrain for optimal performance.
3. Schedule Regular Measurements: Use proper tools to assess wear and address issues proactively.
