Hvem kan vurdere brugte entreprenørmaskiner?

Der er flere måder at få vurderet brugte entreprenørmaskiner i Europa på. Her er nogle af mulighederne:

Erfarne maskininspektører:

Der findes specialiserede maskininspektører og inspektører i Europa, som kan foretage inspektioner og vurderinger af brugte entreprenørmaskiner. Disse inspektører kan på professionel vis vurdere maskinernes tilstand, værdi og eventuelle skader. I denne henseende er folk som Mevas mere fleksible og billigere end TÜV eller SGS.

Specialiserede maskinhandlere:

Nogle forhandlere af brugte entreprenørmaskiner er specialiseret i vurdering og salg af brugte maskiner. Disse forhandlere kan foretage en vurdering af maskinernes tilstand og værdi og kan også hjælpe med salget af maskinerne. Der er dog ikke tale om en uafhængig vurdering, da en forhandler altid er interesseret i at købe eller sælge!

Uafhængige vurderingsfirmaer:

Der findes virksomheder, der har erfaring med at vurdere større maskinparker eller alle mobile maskiner og køretøjer i bygge- og anlægsvirksomheder. Vurderingsfirmaer som MEVAS kan tilbyde denne service til gode priser.

Uafhængige rådgivere i forbindelse med salg af entreprenørmaskiner:

Der findes uafhængige rådgivere i Europa, som kan hjælpe med vurderingen af brugte entreprenørmaskiner. Disse konsulenter kan foretage en objektiv vurdering af maskinernes tilstand og værdi og kan også hjælpe med at finde købere eller sælgere til maskinerne. Sådanne rådgivere kan også arbejde i forbindelse med forsikringer eller ved salg af en virksomhed. En god måde er også at sælge maskiner gennem en begrænset auktion.

Det er vigtigt, at du vælger en pålidelig og erfaren ekspert til at vurdere dine brugte entreprenørmaskiner. Du kan undersøge forskellige muligheder og læse anmeldelser og referencer, inden du vælger en ekspert til at udføre arbejdet for dig. Desuden er det vigtigt at beslutte, om du ønsker at kende den aktuelle værdi eller genanskaffelsesværdien.

Käytettyjen koneiden tarkastukset Suomessa

Jos olet ostamassa käytettyä konetta, kuten kaivinkonetta, pyöräkuormaajaa tai nivellettyä kippiautoa, on luultavasti hyvä ajatus tarkastuttaa se asianmukaisesti. Jos kone on lähelläsi, se on helppoa. Lähetät korjaamon työnjohtajan tai mekaanikkosi testaamaan konetta. Sitten voit neuvotella hinnasta. Mutta jos kone on kaukana, jos yrityksessä on liikaa töitä, voit myös palkata ulkopuolisen asiantuntijan. Varsinkin kun kone ei ole Suomessa vaan ulkomailla, siitä tulee mielenkiintoista. Silloin on halvempaa saada asiantuntija paikalle ja se on myös nopeampaa.

Kuka voi arvioida raskaita rakennuskoneita ulkomailla?

MEVAS-tiimi on läsnä yli 20 maassa. Teknikot on koulutettu käytettyjen koneiden tarkastukseen. Tarkastamme kaivinkoneet, pyöräkuormaajat, murskaimet, dumpperit, nosturit ja porauslaitteet louhintaan tai maanrakennukseen. Tarvitsetko ammattimaisen tarkastuksen tai arvonmäärityksen? Onko kyseessä rakennuskone vai kokonainen kalusto? Se ei ole ongelma. Me hoidamme sen.

Mitä maksaa rakennuskoneita koskeva asiantuntijalausunto?

Asiantuntijalausunnon hinta riippuu eri tekijöistä. Kuinka suuri rakennuskone on? Millainen kone se on? Missä rakennusajoneuvo sijaitsee? Ja sitten on tärkeää tietää: Tarvitsetko tietoa vain kunnosta vai pitäisikö myös määrittää nykyinen arvo? Jos lähetät meille tiedustelun, saat tarjouksen ja esimerkki kertomuksen muutaman tunnin kuluessa. Sen jälkeen voit päättää, haluatko palkata meidät arvioijaksi.

Tunnemme hyvin: Caterpillar, Hitachi, Komatsu, Volvo CE, Liebherr & Terex. Tarkastamme ajoneuvonosturit, tiehöylät, yksirumpujyrsimet, kaivurit, paalutuskoneet, leikkurit, pyöräkaivukoneet, materiaalinkäsittelykoneet, kippiautot ja kaikki muut maansiirtolaitteet.

How second-hand machine inspections pay for themselves:

With the rise of online marketplaces and the increasing availability of used heavy equipment, offered over the internet, it can be tempting to take advantage of seemingly great deals on second-hand machinery. However, buying used heavy equipment over the distance can be dangerous and result in costly mistakes.

Many online advertisements can be misleading, with sellers concealing critical information about the equipment’s history, maintenance, and condition. This can result in you buying equipment that is in poor condition, has been involved in an accident, or does not meet safety standards.

That’s where a service provider like Mevas comes in. Experienced inspectors perform thorough inspections on used heavy equipment, providing the customer with a comprehensive report that details the equipment’s condition, maintenance history, and any potential issues.

Using a professional service instead a good friend

By using a professional inspection service, the buyer can be confident that the equipment he is buying is safe, reliable, and fit for purpose. Mevas inspectors have the expertise to identify any hidden problems and assess the overall value of the equipment.

We at Mevas believe that peace of mind is essential when making a large investment, and our inspection services can provide you with the confidence you need to make an informed purchase.

So, the next time you are considering buying used heavy equipment, think twice before making an online purchase and consider using a trusted inspection service like Mevas to ensure a safe and successful transaction. Sending a good friend costs less but is he a real prof?

The cost of inspecting used equipment depends on various factors such as the number of machines, their size, location, and availability of inspectors. However, compared to the value of the machines, the inspection cost is relatively insignificant. An experienced inspector can help calculate repair costs and determine the value of the equipment in its current condition.

MEVAS is led by a German management team and comprises an international team of engineers who have expertise in machinery of various brands, including Caterpillar, Komatsu, Hitachi, Sandvik, and others. The company has a proven track record of inspecting assets for quarry, mining, and construction.

So why does a used machine inspection pay off?

When you buy the inspected machine, you can renegotiate with a detailed inspection report. The seller will still carry out one or the other repair or give a discount. If you do not buy the machine because it has too many hidden problems, an inspection report will have saved you a bad investment. Contact us for a quotation.

Used Machinery Appraisal Qatar

Who can inspect and valuate heavy equipment in the Middle-East?

The World Cup in Doha, Qatar, is currently the talk of the town. Some are talking mainly about the situation of workers preparing for the event. Meva’s inspectors played a different role. After many stadiums and buildings had been erected, a large pile of heavy machinery remained. An investment company asked to evaluate 180 items that were for sale.

Mevas sent a team of inspectors who gathered all the necessary information about the condition of the equipment and its maintenance status. Upon the team’s return, the fleet evaluation was completed within eight business days. All in all, it took us only two and a half weeks to evaluate the entire fleet.

Crane inspection in Qatar

It was a tough job for our team on site. Most Europeans are not used to working in the circumstances with high temperatures and high humidity. They are more able to tolerate the cold. But the guys did a great job. The customer was happy with the performance.

Service and component history

How to find info about service history of used heavy machinery?

When buying used construction machinery, it is particularly important, especially for large machines, to obtain information about the service and component history of the machine. When was the engine changed, when were repairs made to the hydraulic pump, when were axles changed, when was the last service and how old are the oils on the machine. In the used machinery business, machines often go unfathomable ways. If you find a machine in Holland, it is not a foregone conclusion that this machine has also worked in Holland – it may well be that the machine comes from Romania or Finland. So it would be important to get some data. In most cases, however, sellers will not reveal where they bought a used construction machine. With a mini-excavator, this information is not so important. But if you buy a 300 hp wheel loader, you should know what the machine has done before and whether it has been maintained according to the manufacturer’s specifications. An important criterion is whether, for example, the original engine and the original gearbox are still fitted. If this information is missing, the remaining service life of the machine and its components cannot be estimated well.

Forensic search for info about machine maintenance

The best way to find out this information is to do a thorough inspection and look for information about the origin of the machine, e.g. on the stickers in the cabin. If the dealer or seller does not want to provide the information, you can also call the manufacturer’s service partner in the respective country, where you might get the missing information. During an inspection with a contractor one can usually get some info from the local service staff.

Downloading machine info from ECU

On some machines the local dealer or an inspection service such as Mevas can download a summary from the machine ECU or ECM. Especially for Caterpillar and Volvo we can provide such service. The summary contains info about error codes, overheating or engine overspeeding. In some cases we can support with phone contact to service providers in other countries. Due our large network in the international machinery industry we know many people in various countries. Contact us please for a quotation and more info.

How to measure engine blow-by ?

Engine Blow-By: An Overview

A combustion engine operates by burning fuel in a cylinder, where a piston moves up and down. The piston is sealed towards the cylinder by piston rings. However, a certain amount of exhaust gas escapes from the combustion chamber into the crankcase housing, which is referred to as “blow-by.” A visual representation of this can be found at diesel.net.

Checking the Engine for Blow-By

When inspecting a used machine, it is essential to assess the engine for the amount of blow-by. By measuring the amount of escaping gas, an experienced inspector can estimate the engine wear. Typically, this can be done by placing a hand on top of the oil filler tube and checking for the amount of blow. The inspector will also examine the smell of the gas for any signs of burned oil or coolant in the engine lubrication system.

Engine blow-by measurement

On larger engines, it may be necessary to measure the blow-by and compare it with the manufacturer’s specifications. Some inspectors may be equipped with a gauge, called an anemometer, for this purpose. However, it is important for the inspector to have a good understanding of the engine configuration as not all gas escapes through the oil filler tube. Some engines may have a certain amount of blow-by even when new. Inspectors opening filler tubes on Perkins engines can tell stories about it.

Examining Engine Condition through Exhaust Fumes

Experienced technicians can use the appearance and smell of the exhaust fumes to determine the condition of the engine. For example, if the engine is burning oil, the technician may detect a burnt oil odour. The colour and amount of smoke can also provide insights into the engine’s condition. Engine smoke can appear white, grey, grey-blue, or black. If the smoke appears abnormal, the inspector may need to examine the engine systems closely for issues such as malfunctioning injectors or coolant entering the engine lubrication.

Engine oil sampling

Last but not least it is an option to send an oil sample for analysis. A certified lab will provide info about oil condition and containment. Engineers can read a lot from sample as long as it is known how long the engine oil was in use.

Using an inspection app

We are often approached by developers of machinery inspection apps, who believe that anyone can perform an inspection with the right application and guidelines. However, from our perspective, it is still necessary for an inspector to have several years of experience with machines and engines to accurately assess the engine’s condition.

Where to buy a CAT-14-pin cable?

Where can I buy Caterpillar diagnostic cable with the 14-pin plug?

Some recent machines of Caterpillar have a new 14-pin socket for the diagnostic adapter. One option is to purchase from CAT dealer a new cable in a heavy version for almost 250$. Another option is to order it from Mevas. We have bought a package of adapter cables for heavy equipment diagnostic adapter CAT-ET 3. The cable is an addition to the current diagnostic cable with 9-pin Deutsch socket. The cable we are selling is connecting the diagnostic adapter with the socket in the machine.

How much does the cable cost?

We are selling the cable for a fee of 39 Euro plus shipping. If you buy more than one there can be a slight discount. The cable is good for any Caterpillar excavator of the F-Series, it works as well for wheel loaders of M-Series, bulldozers of K-Series and some other machines.

How to order the 14-pin cable?

You can buy online if you just want one cable. Just visit our online store. If you need more than one contact us via our contact form. You can also contact us if you have further questions about the technology of machine diagnostics. We have over 20 years of experience in the diagnosis of construction machinery. Our technicians analyse the condition of many different makes, such as Komatsu, Hitachi, Cummins, Volvo and Liebherr.

What can I do with a Caterpillar diagnostic cable?

What is this cable for? It is part of the so-called Electronic Technician from Caterpillar. You need this tool to make settings on the machine. With the associated diagnostic adapter and software, you can check and change all settings in the machine’s electronic control units. The engineer can check the machine for error codes and upload files for the injectors, for example. As already described, many newer machines have a new plug connection. Unfortunately, the old cable with only nine pins no longer works on these machines. There is a combined cable with both 9 pins and 14 pins available from the Caterpillar dealer. Unfortunately, this cable is relatively expensive with a purchase price of about $250.

Oil analysis for heavy equipment

What is oil sampling and how to do it?

Analyzing the oils used in construction machinery can be useful because you can read information about wear from the contents of the used oil. To do this, a mechanic or technician uses a very clean container and a pump to remove oil, e.g. from the engine, from the hydraulic circuit or from the gearbox. The extracted oils are 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.

Heavy Machinery Oil sampling

When is it reasonable to analyse oils of used heavy equipment?

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.

What influence have working hours and temperatures to oil condition?

As already described above, it is important to know or to be able to estimate the service life of the existing oils. And to get meaningful results, it is necessary to warm up the machine. Otherwise there will be many particles, e.g. 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.

What info does an oil sample report contain and what does it tell us?

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. 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.

By the way, to guarantee high quality of our oil analysis we work on this sector with the lab of Zeppelin Baumaschinen which is the CAT dealer for several countries in Europe.

How to check the hydraulic pump?

How can I check if my excavator hydraulic pump is working well?

In the event that the hydraulic excavator does not have enough power or even when buying an excavator, it is useful to check whether the hydraulic pump has enough power. Normally, however, you do not have any equipment for measuring pressure with you. Don’t forget that pressure alone is not a criterion for sufficient power. You would also have to measure the volume of the oil flow.

Hydraulic Pressure Testing during inspection of an excavator

So what can be done to check the performance of the hydraulic pump?

An excavator usually has a so-called load-sensing pump. The pump’s sensors constantly check the pressure and the oil volume demanded. The pump permanently adjusts the volume flow and the pressure to the requirements during work. To check performance, an experienced inspector will usually test whether the excavator can make three different working movements at the same time without slowing down the flow of one working movement. For example, lifting the boom, extending the arm and extending the bucket at the same time. The inspector must note whether there are one or more hydraulic pumps for the different components. Often the traction drive has a separate pump.

Pressure test for comparison with the manufacturer’s data

The type of test described so far is helpful if you do not have a pressure gauge available. However, for a more accurate test of performance, it is helpful to be able to measure pressures. To do this, the inspector needs to connect a pressure gauge to the test ports and measure the pressures for the pump and the pilot pressure. The recorded data must be compared with the manufacturer’s specifications.

Hydraulic-Pressure gauge for excavator testing

Which company can inspect an excavator with pressure measurement?

Some MEVAS inspectors are equipped with dial gauges. We can offer a very thorough examination of the condition of used hydraulic excavators in various countries. Of course, we are also responsible for any other construction machine and for large equipment from the mining industry. The guide can be downloaded here.
