WEAR PART BULLDOZER D50

Bulldozer as a self-propelled shovel transportation machinery, its main modes of operation are: in the economic transportation distance shovel, shovel, loose materials, the trench, base groove, sewer and other filling, leveling construction site and farmland, or the restoration of the road surface broken.
Bulldozer also has other uses, such as as self-propelled scraper booster, clearing tree stump, snow, as drag roller, drag scraper tractor, etc., in addition to the conveyor, crawler loader, pipe crane, power station and other types of machines are mostly based on the bulldozer undercarraige.

Bulldozer walking mechanism wearing parts of the material, with high carbon manganese steel, such as 65Mn,50Mn, although has high hardness, strength and wear resistance, but toughness, plasticity is low, easy to cause parts failure;With close to low carbon steel or low carbon carbon steel, such as 35 Mn,42 Mn,30 SiMn,42 SiMn, etc., its plasticity, toughness is high, can meet the requirements of working conditions.Take certain heat treatment, still can guarantee the material

Crawler bulldozer is the main engineering equipment of open-pit mining, and the speed of wear and tear of its walking mechanism is the most obvious in the work. Effective measures from the equipment management, operation management and renovation process can improve its service life, reduce the cost of operation and maintenance, so as to improve its comprehensive economic benefits.

The wear condition of dozer crawler walking mechanism is very complicated, and the wear degree of each part is different, and the wear of individual parts will aggravate the wear rate of other parts.But through effective and timely maintenance management and correct operation, can form relatively stable wear, prolong its service life.
