Tower Crane Counterweights
Kurt Foundry casts tower crane counterweight blocks sized to your jib length and maximum load moment — cast in durable gray iron and backed by direct-factory pricing and reliable output.
What We Customize for You
Every tower crane counterweights order is cast to your specification, not pulled off a shelf. Here’s what we tailor to your exact application.
Exact Weight
Every casting is poured and certified to your target mass with tight, documented tolerances – critical for tower crane stability and balance calculations.
Dimensions & Envelope
We match your outer envelope, clearance limits, and mounting footprint exactly, whether you’re replacing an OEM part or engineering a new design.
Bolt Pattern & Mounting
Hole spacing, thread size, and mounting orientation are machined to your drawing so the casting bolts straight onto your tower crane without rework.
Lifting Points & Rigging
Cast-in lifting lugs or eyes are positioned for safe, balanced handling during installation and service on your equipment.
Standard Material: Gray Cast Iron
| Standard / Grade | Tensile Strength (MPa) | Yield Strength (MPa) | Elongation (%) | Common Applications |
|---|---|---|---|---|
| ASTM A48 Class 30 (Gray Iron) | ≥ 207 | – | – | Standard tower crane counterweight blocks — lowest cost per pound. |
| ASTM A48 Class 40 (Gray Iron) | ≥ 276 | – | – | Heavier-duty blocks for tall tower cranes and maximum jib configurations. |
Why Choose Custom Tower Crane Counterweights from Kurt Foundry
Every custom tower crane counterweight we produce is cast, heat-treated, and CNC machined under one roof — engineered to hold the exact mass and mounting geometry your equipment requires.
Exact Mass Control
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 rating and stability calculations hold true.
Custom Bolt Patterns & Lifting Points
Our engineers machine mounting holes, lifting lugs, and locating pins to your exact frame drawing, so the counterweight bolts on without field modification or shimming.
Direct-Factory Supply Chain
Skip the middleman markup on replacement or OEM counterweights. Partner directly with Kurt Foundry for transparent pricing, direct metallurgical support, and DDP shipping to your facility.
Frequently Asked Questions
We typically hold weight within a documented tolerance band and provide a certified scale ticket with every shipment, so your tower crane balance calculations stay accurate.
Our foundry handles castings from a few pounds up to several tons. Send us your target weight and envelope and we’ll confirm feasibility before quoting.
Yes. Send a sample, drawing, or 3D scan and we’ll reverse-engineer the pattern to match your OEM’s dimensions, bolt pattern, and weight.
Yes, we offer post-cast machining, drilling, and surface finishing so parts arrive ready to bolt directly onto your tower crane.
Lead times vary with casting size and volume, but most custom tower crane counterweights orders ship within a few weeks of pattern approval. Request a quote for a project-specific timeline.
