Crane Counterweight Hydraulic Cylinder

What a Crane Counterweight Hydraulic Cylinder Does on Your Crane

The counterweight hydraulic cylinder is the core actuator of a mobile crane's counterweight system. When the boom extends, the cylinder moves the counterweight block in real time to keep the crane's center of gravity inside the safe envelope. Without it, the crane relies on a fixed counterweight — meaning either the lift capacity is reduced or the chassis must be heavier than necessary.

Raydafon's counterweight cylinder works with the crane's hydraulic control system to translate sensor or operator signals into precise counterweight positioning. The result is smoother boom motion, less sway when lifting on windy days, and fewer unexpected shutdowns from imbalance alarms. For buyers sourcing industrial hydraulic cylinders, this is the component that most directly affects cycle time and safety margin.

If your crane uses a different counterweight function — for example a luffing jib system — compare the crane luffing hydraulic cylinder or browse the full mobile crane hydraulic cylinder range before selecting.

Not the size you need? We also build custom counterweight cylinders for other crane tonnage classes. Send the bore, stroke, pressure and mounting interface — or simply forward your drawing number — and our engineers will confirm the match.

Why Procurement Engineers Choose Raydafon Counterweight Cylinders

Three commercial reasons drive repeat orders: longer service interval, lower maintenance labor and stable force output across the full stroke.

Applications: Where Buyers Install These Cylinders

The counterweight hydraulic cylinder is specified wherever a crane must stay balanced while the load or boom position changes. Typical installations include:

Custom Counterweight Cylinders — OEM, Private Label and Drawing-Based Production

Raydafon is an OEM hydraulic cylinder manufacturer, not a trading company. Customization happens inside our own ISO 9001 facility in Ningbo, China — the same line that builds our standard cylinders.

Send a PDF, DWG, DXF or STEP drawing with your working pressure, flow and mounting interface. Our engineers return a sized recommendation and factory price within 24 hours.

Quality Control, Certifications and 12-Month Warranty

Every counterweight cylinder passes a documented inspection route before shipment — the evidence trail overseas buyers rely on for vendor approval and incoming inspection.

• ISO 9001 certified manufacturing process
• Incoming steel verification and heat-treatment records
• Bore honing, rod chrome thickness and surface roughness report
• Pressure test at 1.5× rated working pressure before packing
• Seal fit, stroke and mounting dimension inspection
• 12-month limited warranty against manufacturing defects
