Frequently Asked Questions

What are undercarriage parts in construction machinery?

Undercarriage parts are the components that support the weight and enable the movement of heavy machinery like excavators and bulldozers. Key components include track chains, track rollers, carrier rollers, sprockets, and idlers. Proper maintenance of these parts is crucial for machine mobility and stability.

How often should I replace hydraulic filters on my excavator?

Hydraulic filters should typically be replaced every 250 to 500 hours of operation, or as recommended by the Komatsu (小松) or Caterpillar (卡特) manufacturer's service manual. Regular replacement ensures the hydraulic system remains free of contaminants, preventing costly damage and downtime.

What are the signs of wear on excavator sprocket teeth?

Signs of wear on excavator sprocket teeth include: sharp or pointed teeth, reduced tooth height, uneven wear patterns, and cracks or breaks. Worn sprockets can cause damage to the track chain and reduce the efficiency of the machine's drive system. Timely replacement is essential to maintain optimal performance.
