XCMG Spare: Equalizer Beam 138700328 | XZ100K Series Structural Component

The term "equalizer beam" (balanced beam) points to completely different components across various construction-machinery contexts, which easily leads to confusion when ordering and replacing. The boundaries must be clarified first:

• Lifting/Hoisting context: The equalizer beam, also known as an "iron shoulder pole," is an important tool in lifting operations—used to maintain the balance of the lifted equipment, avoid damage from slings, shorten sling height, balance and distribute loads across multiple lifting points when the component stiffness is insufficient, and to switch lifting points . Common forms include tubular, steel-plate, channel-steel, and truss types .

• Paver context: A paver equalizer beam is an automatic leveling-system component consisting of a controller, ultrasonic sensors, brackets and beam body, and connecting cables—it measures pavement elevation via ultrasound and controls the leveling cylinder's rise/fall to automatically regulate paving thickness .

• Loader/chassis context: A loader equalizer beam is a core force-transmission component connecting the frame to the front and rear axles, evenly distributing the machine's weight and working load to each axle, reducing impact damage to the transmission system and hydraulic components .

• Crawler dozer context: The equalizer beam of a crawler chassis is a core component of the suspension system—through a swing structure it evenly distributes the machine's weight to the left and right tracks and carrier rollers, absorbing ground impact and vibration
