Crane engineering tools
Free calculators and selectors built on the Australian Standards we design to every day. They are for preliminary sizing and sanity checks — every design we supply is still verified by appropriately accredited engineers (state-dependent), and yours should be too.
Crane Selector
Five questions about coverage, capacity, structure, floor and use. Get the right crane type for your application — reviewed by an engineer before we reply.
Start the selector →Bottom Flange Stress Calculator
Check a monorail or underslung beam's bottom flange under the hoist trolley wheels: required flange thickness to AS 1418.18:2024 Clause 5.12.3.1, with wheel centres, dynamic factors and yield strength.
Open the calculator →Wheel & Rail Sizing Calculator
Wheel diameter and rail width to AS 5228.1:2021 (ISO 16881-1): capability and wear equations, PL, c1, c2, useful width and the Australian annex rail check.
Open the calculator →Jib Crane Slab Thickness
What concrete slab a freestanding jib crane needs, what we check on site, and why the answer depends on capacity, reach and the slab you already have.
Read the guide →Disclaimer. These tools are provided for general information and preliminary sizing only. They are not professional engineering advice, not a design verification, and not a substitute for a design by an appropriately qualified (and, where required, registered) professional engineer who has reviewed your actual crane, structure, loads and site. Each calculator page carries the full terms of use.
