A short routine lift takes a minute. The plan only asks for the extra critical-lift detail when it hits the threshold. Same form scales from a 15% utilization shake to a tandem pick over occupied space.
Enter load weight, radius, and configuration. The plan computes capacity percentage and auto-flags critical-lift status at 75% — surfacing the extra documentation those lifts need without the planner remembering to switch templates.
Capacity defaults to 50% per the rule so the planner can't accidentally exceed the derate. Trial-lift, anti-two-block, dedicated comms, and competent-person sign-off all prompted.
Sling type, working load limit, hitch configuration, sling angle factor. Tag rigging from inventory or enter ad-hoc. The PDF references the standard so QA / safety can audit selection downstream.
Outrigger pad size and ground condition inputs produce a GBP estimate the planner verifies against soil capacity or mat rating. Engineer's stamp field stays on the PDF for heavy-soil jobs.
Operator, rigger, signal person, and lift director sign on the same plan in the field. Timestamped digital signatures carry into the PDF — no paper packet to lose between yard and jobsite.
A crane marked Non-Operable on a recent inspection can't be selected for a new lift plan. Catches the failure mode where the deficiency tag never made it to the dispatch board.
The lift plan lives alongside daily / monthly / annual crane inspections and the deficiency-to-mechanic workflow. One login, one billing account, one fleet roster.
Installable PWA caches the lift plan flow. Plan a lift in a cell-dead substation or a rural pad and the plan submits when the device reconnects.
Every plan exports to PDF with the calculations, sign-offs, and equipment context. Slot it into the project file or hand it to a GC's safety team without rekey.
Select from the fleet. Capacity chart, outrigger spread, and current operational status load from the equipment record.
Load weight, radius, rigging, ground conditions. Capacity % calculates live. If you cross 75% the critical-lift detail unfolds automatically.
Operator, rigger, signal person, lift director sign on the same plan. PDF exports, audit log records the sign-off, and the lift is live.
FAQ · BEFORE YOU ASK
Industry consensus and most general contractor prequalification programs treat a lift as critical when load weight reaches 75% or more of the crane's rated capacity at the planned radius and configuration, when the load is suspended over personnel, when a personnel basket is rigged, when multi-crane (tandem) lifts are required, or when the load is unique-shape / one-of-a-kind. DigiDocs auto-flags lifts at the 75% threshold and prompts for the additional documentation those lifts require.
Personnel basket plans default the crane's rated capacity to 50% per 1926.1431(d)(1) so the planner can never accidentally exceed the derate. The form prompts for pre-lift trial-lift documentation, anti-two-block confirmation, dedicated communication, and trained competent-person sign-off — all the conditions the rule requires before personnel can be hoisted.
Yes. The lift plan workflow scales with the lift. A short routine lift fills out in under a minute — load weight, rigging, radius, signed. A critical lift surfaces the extra fields automatically. Use the same workflow for everything and the audit trail is consistent.
The lift plan captures outrigger pad size and ground condition with a calculated GBP estimate, so the planner can verify against the soil bearing capacity or the published mat rating. It's a planning aid, not a substitute for a qualified engineer's calculation on heavy-soil lifts — the field for the engineer's stamp is included on the PDF.
Yes. Crew sign-off captures digital signatures from the operator, rigger, signal person, and lift director on the same plan. The PDF export carries all signatures with timestamps. No paper to lose.
Yes — the lift plan is gated on equipment status. A crane marked Non-Operable on a recent inspection cannot be selected for a new lift plan until the deficiency is repaired and verified. This catches the failure mode where dispatch sends a unit to a job because the field paperwork didn't make it back to the office.
