Giant Crawler Tractor
Features:
With the widespread popularity of wheeled tractors, crawler tractors have become more and more unfamiliar to many domestic users. However, in the actual application of farmland operations, in recent years, the return of crawler machinery has gradually emerged. This change is more due to some irreplaceable advantages of crawler tractors compared to wheeled tractors.
1. Crawler tractors have higher adhesion and greater traction than wheeled tractors. Under the same machine weight, the traction force of the crawler tractor is 1.4-1.8 times that of the wheeled tractor.
2. In terms of traction efficiency, theoretically, the maximum traction efficiency of a wheeled tractor is 55-65%, and that of a crawler tractor can reach 70-80%. That is to say, for a tractor with the same horsepower, the effective power of the wheel tractor engine is 15% more than that of the crawler tractor. The test shows that on hard ground and cultivated land, the traction performance of crawler and four-wheel drive wheel tractors are tested under similar conditions, and the traction efficiency of crawler tractors is about 10-20% higher. Use when 100 hp or more towed.
3. Track tractors have lower ground pressure. The ground specific pressure of various types of crawler tractors from 51.5kW to 132kW is 44.7 ~ 53kPa, while the ground specific pressure of wheeled tractors of the same power level is much larger, resulting in poor tire adhesion and high slip rate. The ground pressure of the wheeled tractor is high. When ploughing, the rear wheel always walks in the furrow, and the shearing effect of the tire on the soil damages the soil structure of the plough layer. After several years of cultivation, a hard bottom layer will be formed under the plough layer of the soil, which is not conducive to soil water storage and moisture conservation and crop growth. Even after deep raking, the small hard lumps remain and the micro structure of the soil is destroyed. The crawler tractor has a lower ground-to-ground ratio and less compaction of the soil than the wheel tractor. The effect of deep ploughing and meticulous cultivation is particularly prominent, which makes the crawler tractor have obvious advantages in low and wetland operations. Use wheel tow.
4. When tractors are working on farmland, the speed of rotary tillage is generally 5~6km/h, the speed of ploughing is generally 7~9km/h, and the speed of harrowing is generally 10~12km/h. At present, the plowing speed of the crawler tractor is equivalent to that of the wheel tractor. Whether it is ploughing, harrowing, sowing and other farmland operations, the crawler tractor is not slower than the wheel tractor, and the traction advantage is very obvious.
Due to its low center of gravity and large adhesion coefficient, crawler tractors have good slope stability against overturning and sliding, and also have the characteristics of small turning radius maneuverability, strong climbing ability and off-road performance. , heavy clay land and wasteland reclamation operations and other heavy-load planting operations, terrace operations, have better adaptability than wheel dragging. Especially in hilly areas, the slope of cultivated land is relatively large, and the soil resistance is uneven, resulting in poor stability, unsafe operation, uneven operation depth and poor operation quality of wheeled tractors when working on slopes. Ground work will significantly improve the quality of work.
5. The crawler tractor is also particularly suitable for farming in harsh soil conditions, especially in field operations in early spring when the soil is not thawed. Generally speaking, the crawler tractor can go to the ground 2-3 days earlier than the wheeled tractor, which is convenient for grabbing the agricultural time. After being equipped with rubber tracks, the crawler tractor can also drive on the road, which is more of an all-terrain work machine.
6. At present, crawler tractors have generally adopted hydraulic power steering, fully enclosed shock-absorbing cabs, optional air conditioners and heaters, digital instruments, etc., and the noise around the ear and driving comfort have been greatly improved. With the application of new technologies such as differential steering, single handle or steering wheel steering control, its handling comfort will become better and better, and it is no longer inferior to wheeled tractors.
7. In the traditional sense, the main disadvantage of crawler tractors is that the walking devices, such as rollers, guide wheels, support rollers and track shoes (commonly known as "three wheels and one plate") wear quickly, the maintenance cost is high, and the operation transition speed is relatively high. Slow, especially with the development of rural road hardening, metal crawler tractors are inconvenient to transfer. To this end, our factory has developed a rubber crawler device, which can be selected by users. After the rubber track is equipped, the vibration and noise reduction effect of the track tractor is obvious, the comfort is greatly improved, and the problem of road transfer adaptability is solved.
Our factory can modify wheeled tractors on the basis of large wheeled tractors. Replace original rubber tires with track wheel bases. We can replace rear tires or replace all tires according to your needs. This way you have a large crawler tractor at a very low cost. If you are interested in our crawler tractor, please leave a message in time, our staff will reply to you as soon as possible.
