Crane Counterweights
Kurt Foundry casts crane counterweights for mobile cranes, crawler cranes, tower cranes, and overhead/gantry cranes — cast in durable gray iron and backed by direct-factory pricing and reliable output.
Our Custom Crane Counterweight Product Line
We cast counterweights for the specific crane platform you run — not a one-size-fits-all block. Here is where our customers put our crane counterweights to work.
Mobile & Truck Crane Counterweights
Slab and center-ballast counterweights are cast to your exact tonnage and carrier stacking sequence, with lifting lugs and locating pins positioned for fast, repeatable rigging at every jobsite.
Crawler Crane Counterweights
Central and superstructure counterweight boxes are cast in heavy sections to match your crawler crane’s load chart, with alloy matched to duty cycle and pin-connection points machined to spec.
Tower Crane Counterweights
Tower crane counterweight blocks are cast in stackable modular sections with integrated lifting eyes, sized to your jib length and maximum load moment for precise, code-compliant ballasting.
Overhead & Gantry Crane Counterweights
Trolley and end-truck counterweights are cast to your bridge crane’s rated capacity and span, holding consistent density so the hoist tracks level under full-rated lift.

Why Choose Custom Crane Counterweights from Kurt Foundry
Every custom crane counterweight we produce is cast, heat-treated, and CNC machined under one roof — engineered to hold the exact mass and stacking geometry your load chart requires.
Exact Mass Control
Crane counterweight performance lives or dies on precise weight, not just outer shape. We control pour weight and verify final mass on every casting so your load chart and tipping-moment calculations hold true.
Custom Stacking & Lifting Geometry
Our engineers machine locating pins, bolt patterns, and lifting lugs to your carrier drawing exactly, so counterweights stack flush and rig safely without field modification or shimming.
Direct-Factory Supply Chain
Skip the middleman markup on replacement or OEM crane counterweights. Partner directly with Kurt Foundry for transparent pricing, direct metallurgical support, and DDP shipping to your facility.
