What material is the excavator s tracks made of?

The excavator's tracks are steel tracks.

Steel tracks are relatively more versatile in terms of their range of use, their service life and the choice of operating conditions.

The crawler must have sufficient strength and rigidity, good wear resistance, and light weight to reduce the consumption of metal and reduce the dynamic load during the operation of the track. The track and the ground should have good adhesion to ensure that sufficient traction can be issued.

Consideration should also be given to reducing driving and steering resistance.

There are two main types of crawler construction: one is made of hard material and composed of many small pieces; The other is made in one piece and is made of a soft rubber-like material. The former can be used for heavy-duty vehicles, but the weight and driving noise are high, while the latter is light-duty and noisy, but can only be used for light-duty vehicles.

The materials are all special steel, the accessory seals are plastic, and the production methods mainly include: forging, machining, heat treatment, and finally assembling the parts.

The main function of the "crawler" is to increase the contact area, reduce the pressure on the ground, and can work smoothly on the soft ground; The function of "crawler" is to increase the friction with the contact surface, which is convenient for climbing operations.

<> picture shows a crawler excavator in action, you can refer to the following.

Generally, there are two kinds of tracks, rubber tracks and steel tracks, in contrast, steel tracks can bear a larger weight of the fuselage, and the service life is longer, but in the case that the weight of the fuselage is not very large, the choice of rubber crawler type small excavator is more cost-effective, this depends on your choice.

Because the excavator needs to adapt to a variety of road terrain when working, it is necessary to use tracks. The excavator (excavator) is an earthmoving machine that excavates materials higher or lower than the bearing surface with a shovel rock bucket and loads it into a transport vehicle or unloads it into a stockpile. Excavator is one of the most important construction machinery models in engineering construction, widely used in excavating buildings and plant foundations, excavating soil materials, stripping mining field covering, quarries, tunnels, underground workshops and stockpiles in loading operations, excavation channels, canals and dredging waterways, and replacing working devices can be poured, lifted, installed, piled, rammed earth and other operations.

Because the excavator needs to transport the car to adapt to a variety of road terrain when working, it is necessary to use tracks. Excavator (excavator) is an earthmoving machine that uses a bucket to excavate materials that are higher or lower than the bearing surface, and loaded into transport vehicles or unloaded to stockpiles. Excavator is one of the most important construction machinery models in engineering construction, which is widely used in excavating building and plant foundations, excavating soil materials, stripping mining overlays, quarries, tunnels, loading operations in underground workshops and stockpiles, excavating channels, canals and dredging waterways, and pouring, lifting, installation, piling, ramming earth and other operations after replacing working devices.

The working device of the loader operation should be able to ensure that this article introduces in detail the characteristics of the rubber track of the excavator, the characteristics of the rubber track walking system, the key points of use and maintenance, the appropriate tension force, and the sharp objects should be avoided during the machine line, so as not to scratch the track'Knowledge.

1. The characteristics of the rubber track walking system

The rubber track slippery and trembling belt has the characteristics of light weight, low vibration, low noise, large adhesion, good ground adaptability, and no damage to the road surface; It is especially suitable for urban road construction.

The basic structure of rubber track and steel track is the same, and it is usually composed of guide wheels, supporting wheels, driving wheels, support wheels, crawlers and walking frames, etc., and its main differences and characteristics are:

1) The rubber track is a rubber molded and the whole continuous track answer, the heart is reinforced with fabric and a number of wire ropes, there are tracks on the outside, and there are transmission parts on the inside. The steel transmission is inlaid in a vulcanized rubber belt. The main parameters of the rubber track are pitch, the number of sections, the width of the track, the pattern style, the style of embedded metal parts, 2) the driving wheel is installed on the walking reducer, used to wind the track, in order to ensure the mechanical driving operation.

The moving wheels for rubber tracks are toothed with a pitch of 128mm. There is bending stress in the process of track work, which will cause fatigue damage to the track, so the diameter of the driving wheel is not easy to be too small.

3) The roller, the supporting wheel and the guide wheel are straddled on both sides of the track teeth, pressed on the rubber plane, in order to prevent the wheel rim from cutting and serious rubber pressure and damage, so the wheel rim is wide: because the track teeth are higher, the wheel body is larger.

2. Key points of use and maintenance

1) There should be appropriate tension. If the tension is too small, the track is easy to fall off; Excessive tension will reduce track life. When checking and adjusting, it is necessary to unilaterally lift the walking system, and its height should be 10-20mm, and when the tension force is small, it can be readjusted by tensioning.

2) Sharp objects should be avoided during the machine to avoid scratching the tracks; Turning too fast on concrete pavement with a high coefficient of friction should be avoided to avoid tearing of the rubber. Under normal circumstances, it is also necessary to avoid turning too fast and too fast, and try not to turn unilaterally when turning.

3) Do not make the track stick to the oil corrosive substance, once found, should be wiped off immediately.

4) When stored for a long time, it should be placed indoors to avoid sun and rain. Before storage, the track should be cleaned to prolong the service life.

5) Replace in time.

Summary. The excavator belt is an important component in the excavator, which mainly plays a transmission role. Specifically, the excavator belt transmits the power of the power source (such as the engine) to the hydraulic components such as hydraulic pumps and hydraulic motors, thereby driving the various tasks of the excavator, such as the lifting, rotating, and telescoping of the bucket.

Summary. Hello dear to your question: there are several belts at the front end of the engine of the excavator transporter, and each belt plays an important role.

On the excavator transport truck engine, various auxiliary engines are driven by belt drive, such as compressor of air conditioner, power steering oil pump, alternator, etc. If the engine belt of the excavator transporter is broken, or there is a slippage, the relevant auxiliary equipment will lose its function, or its performance will be reduced, thereby affecting the normal use of the excavator transporter.

Hello dear to your question, which answer is: there are several belts at the front end of the engine of the excavator transporter, and each belt plays an important role. On the macro engine of the excavator transporter, various auxiliary engines are driven by belt drive, such as compressor of air conditioner, power steering oil pump, alternator, etc.
