Free template and calculators.
The lift plan template is a download. Every calculator below runs entirely in your browser — no server, no data leaves your device.
Lift Plan Template
Word + PDF · BS 7121 / LOLER
13-page blank lift plan structure — cover, load data, crane duty, rigging, ground bearing, L×S risk, method statement, sign-off. Template only. Not a signed operational plan.
Download → FREESimple routine lift plan
Word + PDF · 2 pages
Short operational sheet for a known load on one crane. Not a critical-lift study.
Download → FREELifting method statement
Word + PDF · 2 pages
Common controls already written. Fill [JOB] gaps only. Not an operator procedure.
Download → FREEOffshore routine lift plan
Word + PDF · deck / boat
Short operational sheet for platform, deck and supply-boat lifts — crane, load, comms, sequence, shift sign-off. Template only. Not an operator form.
Download → FREEPre-lift start-work check
Word + PDF · 6 controls
One-page mechanical-lifting start-work check. JMR original — not an official IOGP document. Stop if any control is not true.
Download → NOTESField notes
Power lines · signals · critical
OSHA public clearance table, agreed hand-signal names, and when JMR treats a lift as critical. Not a copy of ASME B30.5.
