Como escolher a placa de esteira para escavadeira de esteira?
Bulldozer Track Shoe é geralmente dividido em 2 tipos, tipo de terra seca, tipo de zona húmida. Cor geral da pintura da placa da esteira do bulldozer para amarelo, barra única. A placa da escavadeira geralmente tem três barras, a cor da tinta é preta. O material da placa do trilho é geralmente 25MnB, e a dureza final do tratamento térmico do material é HB364-444.
Bulldozer Standard crawler The crawler Sapata de esteira EX120 width of bulldozer is generally 510mm or 560mm or 610mm or 660mm, and the crawler plate width of wetland bulldozer is 950mm or 1100mm.
Crawler construction machinery in different working environment should choose different crawler track plate for dozer, so as to improve the efficiency of mechanical work, give full play to its maximum performance.
Loading and snow digging operations. It is appropriate to use half double tooth PC300-5 Track plate, the crawler tooth height between single tooth and three tooth crawler plate, there are two unequal height crawler teeth, has the characteristics of large traction and can prevent frequent steering, such crawler tooth thickness, high torsional and bending strength under heavy load, the disadvantage is that on the hard ground ride comfort is poor.
Wetland bulldozer track shoe and snow track plate should be used respectively on wetland and snow. The cross section of the wetland track plate is 3 arcs, which has large ground area, high buoyancy, no tooth tip PC300 207-70-14151RC bucket teeth, and will not cut off any object on the ground. Both ends have a special arc section to prevent sideslip. The disadvantage is low strength, easy deformation, except wetlands are not applicable. Snow track plate reinforcement, track teeth with steps, can prevent sideslip, board surface cut to the back edge, easy to extrude the ice and snow remaining on the track plate. Tracks are easily worn or damaged if used on common soil and rock.
Work in special environment such as pavement. Flat track plate and rubber track plate can be used in the operation of stone pavement and paved pavement. The former has no crawler teeth, the bolt head is lower than the surface, walking or operating without damage to the road or ground; The latter is to fix the rubber block on the ground surface of the track plate. When the machine walks, it does not damage the road surface, and there is no noise when crawling. The disadvantage is that their scope of application is limited. If high temperature slag is treated, slag is used to treat track plate, which is characterized by high heat resistance, high strength and long life. It can also be used for stone work.
In the purchase of bulldozer crawler, reasonable assembly of crawler plate according to the operating environment and working conditions, different crawler plate has a great impact on the production efficiency of bulldozer and chassis system service life, in the wetland operation, to choose the widened crawler plate (commonly known as wetland plate) when the width of the crawler plate increases, the buoyancy of the crawler plate increases, can adapt to more working conditions; But the maneuverability of the bulldozer decreases, as does the structural life of the excavator track shoe and other parts of the bottom plate. And the wider the track plate, the greater the friction with the ground, the greater the power loss caused by driving, the bulldozer’s fuel consumption response becomes higher.
Another basic principle when choosing a bulldozer track shoe is that the narrower the track plate is, the better, as long as the bulldozer is working without trapping the car. The lower the relative fuel consumption, the higher the efficiency. Portanto, we should consider the ground conditions, application conditions and chassis wear life factors in the selection of VOLVO EC210B track link.
