In the process of road construction, the wheel loader can undertake the work of filling and excavation of roadbed works, and the collection and loading of asphalt mixture and cement mixture. With its advantages of fast operation speed, high efficiency, good maneuverability and light operation, it attracts countless buyers. The price of second-hand loaders is much cheaper than new ones, and for many customers who are just starting out and have limited budgets, a used loader with fewer hours of work and good quality and color preservation is a good choice. However, many buyers also lack certain experience, resulting in being pitted and deceived frequently. So, how should we buy used loaders? Today, Machmall will introduce you to the ten points you need to pay attention to when buying a used loader.

First, the appearance

Check whether the appearance has been refurbished as a whole and whether there is obvious paint loss. Pay attention to matching the numbers of the whole vehicle, engine number, frame number, bridge number.


Second, the frame

First of all, we should carefully observe whether the frame has cracks, deformation, open welding, the main parts include articulation, frame welding. Then hand touch, whether there are cracked places for grinding and repair. Finally, you need to drive a used loader in the field. Start the loader, adjust the throttle to the maximum, bucket lifting, flat driving. After stepping on the brake, judge whether the hitch pin has jumped.

Third, tires

Loaders used for a long time in harsh environments tend to have greater wear and tear on their own, and the tires can be very serious. The tires themselves are more expensive, so when they are sold, many people do not do tire replacement. When shopping, if you find more serious damage to the loader tires, then this loader is likely to have more wear and tear on the job.


Also, check the brand of the tires for a reliable manufacturer. Pay attention to look around the rim, genuine tires are smoother and neater, retreaded tires are usually not smooth and neat. In addition, you also need to look at the edge of the tire with or without openings, with or without patching.


Fourth, hydraulic tank

Open the gas port, smell whether there is a burnt flavor, if so, it means high temperature. Use the ruler, drop a drop of oil in the white, non-reflective paper, see if there is aluminum alloy powder, there is a problem with the turbine.


Fifth, the engine

Check whether the appearance of the engine is clean, whether there is the phenomenon of oil leakage, start whether sensitive. There should be slight blue smoke when the cold car is just started, no blue smoke when the engine is warmed up, slight black smoke when refueling door is opened, and basically no smoke when the lower exhaust is normal.

Sixth, bucket

Bucket is the most serious wear and tear in the work of the loader, but it is also one of the most important working devices. Therefore, in order to ensure that the loader can be put into good use, must strictly do a good job of bucket wear check, judge the age of the car, to avoid choosing to the poor quality of the loader. Selection should look at the thickness of the knife plate, side plate, bottom plate whether deformation.


Seventh, the water tank

Check the heat dissipation of the water tank, whether there is scale.


Eighth, gearbox

Confirm that the gearbox has no equal gears, oil pressure problems, to ensure that the gearbox works powerfully, to avoid the loss of efficiency. In addition, in the transmission test at the same time, for the loader's work pump also affects the appropriate test, to avoid serious wear and tear, to prevent the loader may have a slow lift arm and other problems.


Ninth, hydraulic system

Check whether the operation is smooth, do a single action to see whether the engine is off, refueling door piping connections whether oil leakage. Check the hose of the whole machine, hose generally 2-3 years will crack, if the whole machine on the face of the hose are full of cracks, especially under the cab to beware.
