The cylinder that positions the counterweight for crane stability. Mounted in left\/right pairs, counterweight cylinders extend or retract the counterweight assembly \u2014 adjusting its radial distance from the crane’s centre of rotation to balance the moment created by the boom and suspended load. Correct counterweight positioning is essential for crane stability at every boom angle and load combination.<\/p>\n

How Counterweight Positioning Ensures Crane Stability<\/h2>\n
<\/div>\n

\"Truck<\/p>\n

A truck crane’s stability depends on the balance between the load moment (boom length \u00d7 load weight) and the counterweight moment (counterweight distance \u00d7 counterweight mass). As the boom extends or the load increases, the counterweight must move outward to maintain balance. The counterweight cylinder provides this adjustment.<\/p>\n

The 180 mm stroke provides the range of counterweight positions needed \u2014 from fully retracted (for transport, keeping the crane compact) to fully extended (for maximum lifting capacity at long boom radius). The \u03a6200 bore at 21 MPa produces approximately 660 kN \u2014 enough to push the multi-tonne counterweight assembly along its rails against friction and gravity.<\/p>\n

Left and right counterweight cylinders must extend equally \u2014 any asymmetry shifts the counterweight off-centre, creating a side-loading condition that reduces crane stability. Korea Ever-Power supplies counterweight cylinders in matched pairs from the same production batch. Browse the full mobile machinery hydraulic cylinder<\/a> range.<\/p>\n<\/section>\n

Counterweight Positioning: The Stability Equation<\/h2>\n
<\/div>\n
\n
Load Moment Must Never Exceed Counterweight Moment<\/strong><\/p>\n

If the load moment exceeds the counterweight moment, the crane tips. The counterweight cylinder positions the counterweight to maintain a safety margin at every boom angle and load combination \u2014 typically 15\u201325% margin per crane standards.<\/p>\n<\/div>\n

Transport vs Lifting Configuration<\/strong><\/p>\n

For road transport, the counterweight retracts (cylinder retracted) to keep the crane within road width limits. For lifting, the counterweight extends (cylinder extended) to maximise stability. The 180 mm stroke covers this range.<\/p>\n<\/div>\n

50% Rod Ratio for Balanced Force<\/strong><\/p>\n

Unlike the anti-tilt and luffing cylinders (80%+ rod ratio), the counterweight cylinder has a 50% rod ratio \u2014 providing balanced push and pull force for moving the counterweight in both directions.<\/p>\n<\/div>\n<\/div>\n<\/section>\n
