Requirement record
Organize load, span, lift, duty and environmental inputs in one opportunity context.
Product capabilities
A quotation workspace shaped around engineering decisions.
Cranelume connects the work that happens between an incoming crane requirement and a reviewable commercial draft. Each layer stays explicit, inspectable and owned by people.
01 / Understand
Structure requirements before sizing starts
Capture the operating context that gives a calculation meaning, rather than reducing an opportunity to a single capacity field.
Visible assumptions
Mark unknowns and preliminary assumptions so reviewers know where confirmation is still required.
Revision context
Keep changes tied to the draft instead of losing decisions across disconnected files.
02 / Engineer
Deterministic results with an inspectable path
Calculation functions produce numeric outputs from explicit inputs. Generative assistance may explain or navigate, but it does not invent engineering values.
Preliminary sizing
Support early-stage engineering checks that help a bid team frame a feasible concept.
Calculation evidence
Expose inputs, outputs and warnings for technical review.
Clear boundary
Keep pre-engineering separate from project-specific verification and production release.
03 / Compose
Translate the concept into a Macro-BOM
Major assemblies
Group provisional crane components into a quote-oriented structure.
Commercial context
Connect quantities and catalogue choices without hiding the source or currency basis.
Alternatives
Present options as reviewable choices, not silent substitutions.
04 / Govern
Make review part of the workflow
Draft state
Keep preliminary outputs visibly marked until an authorized review is complete.
Revision trail
See what changed between quotation iterations and preserve decision context.
Approval context
Record the human review point instead of implying automated production approval.
