How To Choose a Loader?

Jan. 06 , 2020

Currently, there are many types of mucking loaders. The economic situation of the user and the construction situation to be faced are the most important basis for purchasing the machine. What kind of working conditions determine which machine can bring the largest input-output ratio.

What kind of loader should I pick?

For pavement construction operations and large coal mines, due to the large workload, long working cycle, and spacious working environment, the supporting load capacity of the supporting transportation machinery is more than 10 tons. At this time, 5 tons or 6 tons should be selected. Weight mining loading machine, which can improve operating efficiency and reduce construction costs.

For relatively small workloads, such as earthmoving, river sand and other operations, generally a 2 ton or 3 ton loader can be selected.

For particularly small workloads, such as small individual gravel yards, the supporting vehicles are generally small tractors, and generally a loader of 1.5 tons or less can be selected to avoid excessive loader capacity and thereby achieve economic and practical purposes.

For those materials with higher density such as solid raw soil, ore, etc., due to the higher requirements on traction, loaders with lower working speed and larger digging force and traction force should be selected to ensure normal use.

What should pay attention to when choosing a rock loader?

Exterior:

See if it's a painted car. Pay attention to match the car number, engine number, frame number, bridge number.

Frame:

Carefully inspect the front and rear frames for cracks, welds, paint repairs, and deformation. If there is, it depends on whether it is an important location (hinges, frame welds, etc.). When you see a doubt, touch it with your hand. Sometimes it is repaired by cracking the place. It may not be able to see it by looking at it with your eyes. You will definitely feel it when you touch it with your hands.

Set the throttle of the starting equipment to the maximum, lift the bucket, run straight on a flat road, and after stepping on the brake, determine whether there is any movement or jump at the hinge pin. If the beating is very strong, this car may be overpowered (how to feel the amount of movement, you can feel the new machine to make a comparison, so that you know something).

Tire:

Loaders used in harsh environments for a long time often have large losses themselves, and tire wear can be very serious. The price of the tire itself is relatively high. If you find that the tire of the loader is seriously damaged when you buy it, you must pay more attention to it. This loader is likely to wear a lot of work, and the use of components must be deepened. Make a good judgment.

In addition, don't just look at the old and new tires, the new ones may be full-turn tires, look at the brand of the tires, write down and check. Full turn around look at the rim (in the gap between the tyre and the rim). Genuine tires are relatively smooth and tidy, and retreaded tires are generally not smooth and tidy; semi-turned tires are easier to see. Old tires need to look at the teeth, whether there are openings on the sides, the size of the openings, and whether there is repair.

Hydraulic box:

Open the filler port and smell the smell of burnt paste. Using a ruler, drop a drop of oil on white, non-reflective paper to see if there is aluminum alloy powder, which indicates that there is a problem with the turbine. Normal oil should be clean and reddish.

engine:

The appearance should be clean, check for oil leaks, and whether the startup is sensitive. When the cold car is started, there should be a slight blue smoke, there is no blue smoke in the hot engine, there is a slight black smoke in the gas valve, and there is basically no smoke when the lower exhaust is normal. If there is smoke, it should be white.

Another little experience is to see whether the engine coolant is water or antifreeze. Car owners who add antifreeze are more concerned about the machine. If possible, disassemble the air filter to see if the air inlet is clean. The air inlet of the well-protected machine is clean. The sealant can also be used to determine if the engine has been repaired.

Bucket:

The bucket is the most worn part of the loader, but it is also the most important working device. Therefore, in order to ensure that the loader can be put into use very well, everyone must strictly check the bucket wear and tear, determine the age of the car, and avoid choosing a loader with poor quality. When selecting, you should look at the thickness of the knife plate, whether the side plate and the bottom plate are deformed, and the thickness.

Water tank:

The water tank must be completely cleaned for 3 years, otherwise the heat dissipation is definitely not good. If the water tank is damaged and blocked by scale, the water tank will leak as soon as the scale is washed away during cleaning. If you can make up, you can make up for it. If you can't make up, it will cost you thousands of oceans!

Gearbox:

Confirm that the gearbox has problems with equal gears and oil pressure, ensure that the gearbox works effectively, and avoid loss of efficiency. In addition, when testing the gearbox, the working pump of the loader also affects the proper testing, to avoid serious wear and tear, and to prevent the loader from having slow lift arms and other problems.

Hydraulic system:

See if the operation is smooth, do a single action to choke, see if the engine stalls (idle speed), and if there is any oil leakage at the gas pipe connection.
