Open Crane Data

The first open, machine-readable crane specification database

Crane load charts, outrigger data, counterweight configurations, dimensions, and rigging specs — all locked in PDFs across 50+ manufacturers with zero interoperability. We're building the open standard that changes that. CraneML: one protocol, every crane, free and open.

CraneML Protocol

Machine-readable JSON-LD format for crane specifications, load charts, and lift plans.

Validated Data

Every number traced to its source document. Automated structural integrity checks across all entries.

Open & Free

Data under CC-BY 4.0. Protocol under Apache 2.0. No vendor lock-in, no paywalls.

API Access

RESTful API with JSON responses. Integrate crane data into lift planning tools, fleet management, and BIM platforms.

Standards Compliance

Full support for both EN 13000 (metric) and ASME B30.5 (imperial) load charts. Canonical-metric storage with original-value provenance — every number traces back to its source.

Frequently Asked Questions

What is Open Crane Data?

Open Crane Data is a free, open database of crane specifications including load charts, outrigger configurations, counterweight data, dimensions, and rigging specifications for over 2,000 crane models from 50+ manufacturers. All data is published in the CraneML machine-readable format under CC-BY 4.0.

What is CraneML?

CraneML is an open, machine-readable JSON-LD protocol for representing crane specifications, load charts, and lift plans. It provides a standardized format so that crane data from any manufacturer can be consumed by software systems, lift planning tools, and engineering applications. Licensed under Apache 2.0.

Is the crane data really free?

Yes. All crane specification data is published under Creative Commons Attribution 4.0 (CC-BY 4.0). The CraneML protocol is under Apache 2.0. Use, modify, and redistribute freely with attribution. No vendor lock-in, no paywalls.

Does it support both metric and imperial units?

Yes. CraneML uses a canonical-metric-with-provenance model. All data is stored in metric (SI) units internally, but original values and unit systems are preserved as metadata. EN 13000 and ASME B30.5 load charts are treated as distinct, auditable datasets with full traceability.

Are 3D crane models available?

Parametric 3D crane models (glTF, FBX, STEP) are available as a premium service. The open database provides all the dimensional and specification data needed to generate models — the generation engine itself is a commercial offering. Contact us for pricing.
