O material rodante de uma escavadeira inclui os trilhos, rolos, rodas-guia e outros componentes que transferem o peso da máquina para o solo e permitem o movimento. Desgaste nas principais peças do material rodante da escavadeira Liebherr pode levar a problemas de desempenho, downtime and costly repairs if not maintained properly.
Among the most critical Peças para escavadeira Liebherr to regularly inspect:
sapatas de pista
The outer plates on the track chains that provide traction and protect the track frame from wear. À medida que as sapatas da pista se desgastam devido ao impacto e à abrasão, they cause damage to internal parts and reduce machine traction.
Check track shoes routinely for signs of wear beyond specifications. Broken or damaged shoes can quickly lead to excessive roller, bushing and idler wear. Replace individual track shoes or do a full track shoe set replacement as needed for optimal performance.
Track Bushings and Pins
The bushings provide pivoting surfaces for the rollers and idlers while the pins securely join links in the track chain. They are constantly exposed to impact and vibration.
Worn bushings with excessive play and damaged or missing pins can cause internal component misalignment, aumentando o estresse em trilhas e quadros. Regularly grease bushings and check pins for proper retention. Replace worn bushings and damaged pins promptly.
Rollers and Idlers
The numerous rollers and idlers within the track frames provide support and guidance for the tracks, reducing friction and extending the lifetime of other parts.
Worn or damaged rollers and idlers allow tracks to sag, placing undue side loads on the track links and frames. Inspect for damage like flat spots, worn bushings and loose or missing hardware. Replace as necessary to avoid costly track repairs in future.
Componentes de esteira de borracha (if applicable)
Some Liebherr excavators use rubber tracks for lower noise and vibration. They consist of rubber shoes, blocos, guides and end connectors.
Cuidado com rachados, loose or missing rubber components that can allow debris into tracks, acelerando o desgaste das peças internas. Replace individual rubber track parts and shoes as required to extend the lifespan of rubber tracks.
