Counterbalance for National Crane 600C

The counterbalance acts as a critical weight component installed on the rear of the crane's superstructure. Its primary function is to offset the tipping moment generated by the load being lifted and the weight of the boom assembly. By providing a counteracting force, this component helps maintain the center of gravity within the operational limits of the crane, which is necessary for preventing instability during heavy lifts at various radii.

This part, identified by part number 972987, is compatible with National Crane 600C, 600B, and N65 crane models. It is engineered to fit these specific truck-mounted crane configurations, ensuring proper weight distribution across the chassis. The component attaches to the superstructure using secure mounting points to ensure it remains fixed during all crane movements and rotations.

In heavy machinery, counterweights are used to maximize the rated lifting capacity of the unit. They are typically positioned to counteract the load moment, allowing the crane to operate efficiently across its full working range. Proper installation and secure attachment are required to ensure the crane functions within its design parameters for stability and safety.
