Lift Weight Buildup — Machine on Skid
Gross weight build-up for a machine on skid lift: net + attachments + rigging + moisture/variance allowance.
Machinery moves quote the MACHINE; the lift includes the skid (5–10%), the lube reservoir someone topped up, and the pipe spools 'temporarily' left attached. Millwright tradition drains and strips before the hook — this buildup is the checklist version of that tradition.
Formula
Note: Rigging and crane decisions are life-safety critical. This calculator is a planning aid — the load chart, sling tags, site lift plan and a qualified lift director govern every real lift.

About Lift Weight Buildup — Machine on Skid
Lift Weight Buildup — Machine on Skid computes the governing relationship gross = (net + attachments + rigging) × (1 + allowance) live as you type. Machinery moves quote the MACHINE; the lift includes the skid (5–10%), the lube reservoir someone topped up, and the pipe spools 'temporarily' left attached. Millwright tradition drains and strips before the hook — this buildup is the checklist version of that tradition. Defaults are pre-filled with realistic values for this exact scenario, and the worked example substitutes your numbers step by step so the math is never a black box.
How to use Lift Weight Buildup — Machine on Skid
- 1Enter your values — Catalog/nameplate weight, Attachments (skid steel, attached piping), Rigging (slings, spreader, block), Variance/moisture allowance (sensible defaults are pre-filled).
- 2Read the live results: Gross lift weight, In tonnes.
- 3Check the "with your numbers" line to see gross = (net + attachments + rigging) × (1 + allowance) substituted step by step.
- 4Adjust inputs until the scenario matches yours, then copy or share the result.
Why use Lift Weight Buildup — Machine on Skid?
- ✓Instant, free and private — every calculation runs client-side in your browser; nothing is uploaded
- ✓Built on the stated formula gross = (net + attachments + rigging) × (1 + allowance) with authoritative sources cited on the page (ASME B30.5/B30.9/B30.20 — Cranes, slings and below-the-hook devices; OSHA 29 CFR 1926 Subpart CC — Cranes & derricks in construction)
- ✓Machinery moves quote the MACHINE; the lift includes the skid (5–10%), the lube reservoir someone topped up, and the pipe spools 'temporarily' left attached.
- ✓SI ⇄ Imperial toggle converts your inputs in place, so you can work in the units your drawings use
Frequently asked questions
What formula does the lift weight buildup — machine on skid use?+
It evaluates gross = (net + attachments + rigging) × (1 + allowance), exactly as published. Sources: ASME B30.5/B30.9/B30.20 — Cranes, slings and below-the-hook devices; OSHA 29 CFR 1926 Subpart CC — Cranes & derricks in construction. The substituted worked example on the page lets you verify every step against the textbook.
How should I read the result — and how far can I trust it?+
