Which of the following factors causes excessive wear of bulldozer undercarriage components?
Answer (1)
Excessive wear of bulldozer undercarriage components is usually caused by a combination of operating conditions, maintenance practices, and terrain type.Abrasive TerrainCause: Operating the bulldozer on rocky, sandy, or gravelly surfaces.Example: A bulldozer working in a quarry or on sandy soil will experience faster wear on the track links, rollers, and idlers due to constant grinding by abrasive materials.Poor Track TensionCause: Tracks that are too tight or too loose increase stress on components.Example: If a bulldozer's track is overly tight while pushing heavy loads, it puts strain on the rollers and links, causing premature wear.Improper OperationCause: Sharp turns, sudden stops, and high-speed operations increase friction and pressure on undercarriage parts.Example: An operator making constant sharp turns on concrete or asphalt while grading can cause the sprockets and bushings to wear down quickly.Lack of MaintenanceCause: Failure to clean, lubricate, or inspect undercarriage parts regularly.Example: Not removing packed mud or debris around the rollers and sprockets can trap moisture and grit, accelerating rust and grinding wear.High Impact or Heavy LoadsCause: Regular exposure to very heavy loads or impacts.Example: Constantly pushing large amounts of heavy rock or debris in construction sites can put more stress on track chains and pads.
