Blue and small make up for the guys to bring about judgment of second-hand excavator working hours a little knowledge, do not know to have bring you some help. Work hours is just let's second-hand excavator check one aspect of the choose and buy, and let's go to check a second-hand excavator is actually depends on many aspects, let's talk about the content of the test vehicle in current test need to pay attention to small details.

Some detail aspects of second-hand excavator is the most can reflect the real condition of the equipment, the use of excavator working condition, whether had an accident, what major did repair, replacement and former owners of excavator spare degree can be reflected in some detail aspects, even if some details about us for a device of choice. Then follow small make up take a look at it today what is need to pay attention to details!

For a second-hand excavators, whole vehicle shiny paint may not be a good thing, in addition to the prospective new car, this kind of excavator is likely to be great to do a full car paint, and paint again always to hide some problems, some for the vehicle look better, some are excavator has experienced some accident needs to be done to restore.

, of course, some detail touch-up is another matter, let's drive carefully every day will inevitably some of the party, after all it is a big guy, and often down on the river, in the face of all kinds of complicated conditions, counterweight to rub off the paint and a side door is normal things in particular, will not special influence on the value of the excavator.

So how to judge from some details this digger had done all car spray paint? Because we excavator factory after spray paint won't will each parts removed independently, all in the joint of many structures can see some traces of paint again.

Cab door frame and hinge, for example, when testing can look at the bridge of the sealing strip is stained with paint, this is the easiest way to observe a place, because new car is a good door plank of spray paint drying after the installation of strip, the original car strip with paint. Cab hinge of the new car factory usually paint alone again after assembling, and if all do paint of second-hand excavator probably wouldn't be so carefully removed, the hinge is easy to see that given.

The choose and buy second-hand excavator engine, pump and the distributing valve is a few places, we will check then we should pay attention to what?

Are on the look of it we first have to judge did this engine overhaul, engine cylinder head bolts, if overhaul a bolt is sure to tear open outfit, this bolt will leave traces.

Or is the appearance of the engine, the outward appearance is too clean that also have to be careful, normal use the engine of a lot of dust dirty is very normal, after all we excavator working environment common dust is bigger, but if the engine and engine bay are white powder that we also need to keep an eye, often need to figure out whether this digger once dry stone or is often working in the mine.

Also we need to focus on whether the engine oil, may leak less, generally there might be oil leakage, is easy to appear the parts is around the edge of cylinder head, oil pump and oil sump, generally appear oil leakage places can see oil sludge is heavy.

Large pump and distributing valve, too, need to carefully observe the external bolt and the flange with engine joint bolt if there is a trace of demolition, the pump is important to pay attention to a detail is regulator ever move, the governor general is for adjusting the flow of the pump, excavator factory before flow is adjusted to a suitable value, if we check the second-hand excavators found flow changed the words that will need to rethink the value of the equipment, is a bigger problem.

There is a place where it is easy to be neglected is the overflow valve, overflow valve is used to adjust the hydraulic oil pressure, this value is adjusted when excavator factory, if the check to the overflow valve is adjusted phenomenon that also have to keep an eye, you need to determine whether the digger of boring phenomenon.

Professional personnel may, of course, there are more professional detection methods, such as start engine sounds, check out speed, upper and lower exhaust work is normal, and so on, these we may emerge in the next content to just talk about it's easy to check some details today.

Water tank is also our many users easily ignored when check second-hand excavators, if not careful buy a winter of excavator working that's pretty pathetic.

Part of excavator easy to appear the phenomenon of high temperature in summer, and easy to heat the excavator to often can see on top of the tank problem, first of all, is to examine the antifreeze, can see the very simple open the tank cover, but it happened that when a lot of user testing we ignored it.

Open the tank cover is to determine water tank with antifreeze or water inside, general water temperature normal car inside add antifreeze, excavator working process of the consumption of antifreeze is not big. If it is easy to high temperature in summer car, due to the fast water tank internal consumption, many inside the water tank is ordinary tap water. Long-term use of water as coolant tank is easy to rust, open the tank cover can see clearly the rust.

There is also a place to judge the place of water tank without rust, that is the drain valve, tank, generally at the bottom of the tank, vehicle examination can open the valve and see out of the water is what kind of, if is long-term add tap water equipment at the bottom of the tank will accumulate a lot of rust, open the valve can be see clearly.

Easy to high temperature in summer of excavator to cool besides often add water, common methods and replace the radiator fan, common method is to replace the leaf number more fans, such as the original car five hakaze may change into seven leaf, so let's talk it over at the time of testing can query the original basic what type of car fan, then contrast at the site.

For our operator, bridge is a mobile home, at work may spend most of their time is in the inside of the cab. Gunner whether love this digger came from cabin also can see some problems, if a excavator cab clean and neat, the accessory tools what is not in the cab with a throw, air conditioning, no peculiar smell, that I also can preliminary judgment of the manipulator is very spare equipment, cab can tidy up so well that it may digger overall situation is not too bad, machinist at ordinary times will certainly pay attention to maintenance.

, of course, we mean under normal working state of second-hand excavator, if it is on the second-hand market may bridge of the equipment has been carefully cleaned clean, very clean, this can't determine whether the previous main spare equipment.

Let's excavator in the factory when the forearm, bucket, and are on each cylinder seal, seal content may be some man, Numbers, or letters, different manufacturers tag way is different, but the steel seal on the same digger content should be consistent, most also can pass the information on the steel seal reflects the production date of the parts.

So we looked in a second-hand excavator keep an eye on each cylinder information are consistent, which can determine the oil cylinder is original, which is to be replaced.

Excavator whole vehicle hydraulic tubing also is such, each root on the tubing has a string of Numbers, let's test the car check all tubing of these Numbers can help determine which tubing is changed, if you are replacing the more the number of tubing to illustrate the digger the more hours worked, working condition of the poor.

For us of each user, the purchase of excavator is a big thing, buy a satisfied second-hand mining function bring generous returns to us, even if accidentally buy refurbished car accident car, will bring huge profit loss for both of us.

Choose a second-hand excavator check project should be fully, small make up mentioned in this article is some details need to pay attention to check, hope to help everyone, small make up the next articles will continue to bring about second-hand excavators of choose and buy, you have a good idea if welcome message at the bottom of the article.
