Ten highlights teach you how to choose a used loader

After a long time of operation, the second-hand loader has a certain degree of impact on its own quality. Enter the second mobile phone market, in the face of a dazzling array of machines, which is your "true love"? How to pick the best, pass the five passes, take their own satisfaction with the loader home?
appearance
Check to see if the car is painted. Pay attention to match the number of the whole car, engine number, frame number, bridge number. Under normal circumstances, the numbering date of each part is not too long apart, generally not more than 3 months, more than too long it is necessary to consider whether it is refurbished assembly.
frame
Carefully check the front and rear frame for cracks, welds, paint, deformation. If so, it depends on whether it is an important position (hinge, frame welding, etc.). Touch where you see suspicion. Sometimes the cracked areas are polished and repaired, which may not be visible by eyes alone, but will be felt when you touch them with your hands.
The throttle of the engine equipment is adjusted to the maximum, the bucket is lifted, and the straight line is run on the flat road. After stepping on the brake, determine whether the hinged pin is moving and jumping. If the beating is strong, the car may be out of strength (how to feel the momentum, you can feel the new machine to do a comparison, so that you know).
tyre
The loader used for a long time in a harsh environment, its own loss is often large, and the tire wear will be very serious. The price of the tire itself is higher, so when it is sold, many people do not replace the tire, in this regard, it is more accurate to determine the loss of the loader through tire wear. In the purchase, if the loader tire is found to have more serious damage, then we must pay more attention to, this loader is likely to work wear larger, for the use of parts also have to in-depth judgment.
In addition, don't just look at the old and new tires, the new may be full turn tires, look at the brand of tires, write down and then check. Look around the rim (inside the gap between the tire and the rim). Genuine tires are relatively smooth and neat, and retreaded tires are generally not smooth and neat; A half turn is easier to see. The old tire depends on the teeth, whether there is an opening on the side, the size of the opening, and whether it is filled.
Hydraulic tank
Open the oil mouth, smell whether the burnt taste, if there is a high temperature. Using a ruler, drop a drop of oil on a white, non-reflective paper to see if there is aluminum powder, indicating that there is a problem with the turbine. Normal oil should be clean and reddish.
engine
The appearance should be clean, check whether there is any oil leakage, and whether the startup is sensitive. When the cold car is just started, there should be a slight blue smoke, the heat engine has no blue smoke, the fuel door has a slight black smoke, the lower exhaust is normal, basically no smoke, if there is smoke, it should be white, if the blue smoke should be careful.
There is also a small experience, is to see whether the engine coolant is water or antifreeze. Add antifreeze owners are more care for the machine. If possible, disassemble the air filter to see if the inlet is clean. The inlet of a well-protected machine is clean. The sealant can also be used to determine whether the engine has been serviced.
bucket
The bucket is the most seriously worn part in the work of the loader, and it is also the most important working device. Therefore, in order to ensure that the loader can be put into use well, we must strictly check the wear of the bucket, judge the age of the vehicle, and avoid choosing a loader with poor quality. When selecting, we should look at the thickness of the knife plate, whether the edge plate and the bottom plate are deformed and the thickness.
cistern
The car with water must be completely cleaned for 3 years, otherwise the heat dissipation is certainly not good. If the tank is damaged and blocked by scale, the scale is washed off when cleaning, the tank will leak. If it can be repaired, it will cost you thousands of dollars!
gearbox
Confirm whether the gearbox has equal gear and oil pressure problems to ensure that the gearbox works effectively and avoid loss of efficiency. In addition, at the same time of transmission detection, the working pump of the loader also affects the proper detection to avoid serious wear and tear, so as to prevent the loader from having problems such as slow lifting arm.
Hydraulic system
See whether the operation is smooth, do a single action to suffocate, see whether the engine is turned off (idle), and whether the fuel valve pipeline connection is leaking oil. Check the hose of the whole machine, the hose will generally crack in 2-3 years, if the hose on the surface of the whole machine is full of cracks, especially under the cab (that place does not blow the wind and rain for a long time) should be careful.
The second phone water is very deep, it is difficult to buy a satisfactory machine without a fire eye. So in the purchase process, do not let go of any details.
At present, there are many kinds of second-hand loaders in China. The economic situation of the user and the construction situation to be faced are the most important basis for the purchase of the machine, and what kind of working conditions determine which machine can bring the largest input-output ratio.
