High-Quality A35 Brake Pump for Reliable Excavator Performance

   When operating an excavator, the machine's ability to move smoothly on gravel and avoid getting stuck in muddy roads all relies on the "undercarriage components" of the chassis—including track rollers, carrier rollers, idlers, drive sprockets, and tracks. These 5 components, collectively known as the "chassis frame," support the machine's weight of dozens of tons while adapting to various complex working conditions.

   This article uses plain language to explain the undercarriage components thoroughly: covering their structure and principles, vulnerability risks, cost-performance comparisons of domestic and foreign brands, and daily maintenance tips—helping to make your excavator's chassis more durable and reliable!

   When an excavator's power fades—with the bucket struggling to dig or the boom failing to lift—the cause often lies in the silent powerhouse: the hydraulic cylinder. Many take this component for granted, facing expensive repairs and project delays only after a breakdown occurs. This article explains how cylinders work, reveals hidden risks, compares brands for cost-effectiveness, and offers practical maintenance strategies to avoid unexpected failures.

   As an engineering equipment manager, are you often frustrated by sudden excavator breakdowns? Even with regular maintenance, frequent issues still occur; repair costs remain high, and construction schedules are delayed?

   In fact, most faults follow predictable and solvable patterns. Below, we break down 10 common maintenance pain points using a "Problem (Why) + Solution" format to help you save unnecessary expenses and extend equipment lifespan!

   Have you ever faced these frustrations while operating an excavator? The machine jerks when you try to lift the boom and swing the upper structure at the same time; the bucket suddenly loses power when digging hard soil; and a single repair can cost tens of thousands of yuan? In fact, 90% of such problems stem from the Main Control Valve—it acts as the "motion control center" of the excavator. Every movement of the bucket, boom, and tracks relies on it to distribute power. However, many operators only master basic operations, without understanding its working principle, knowing how to choose a reliable model, or performing proper daily maintenance.

   This article will explain the main control valve in simple terms: from its structural principle and vulnerability risks to cost-performance comparisons of domestic and international brands, as well as daily maintenance tips. Even beginners can easily grasp this knowledge, helping you reduce repair costs and improve the smoothness of the machine's movements!
