LIFT DIRECTOR — PART 1

You Must Also Pass Operator & Rigger II Exams

Many candidates don't realize CCO requires passing the Mobile Crane Operator Core, TLL or TSS Specialty, LAT Specialty, AND Rigger Level II exams in addition to the Lift Director exams.

Critical Lift Threshold (75%–90% of Capacity)

A lift becomes 'critical' at different thresholds depending on the governing standard — know OSHA 1926 Subpart CC's definition vs. site-specific plans.

Pre-Lift Meeting Requirements

A pre-lift meeting is mandatory before every critical lift and personnel lift. Many test-takers confuse this with routine daily tailgate meetings.

Load Chart Hierarchy of Authority

The rated capacity on the load chart is the maximum — site conditions (wind, ground, geometry) often require you to use LESS than the chart allows.

Lift Director vs. Crane Operator Boundaries

The Lift Director directs the lift; the crane operator retains final authority to refuse an unsafe operation. Confusing these roles is a frequent mistake.

Multi-Crane Lift Written Plan Requirement

Any multi-crane (tandem) lift requires a written lift plan prepared or approved by a qualified person — not just verbal coordination between operators.

Site Assessment Must Precede Every Lift

Ground bearing capacity, overhead hazards, wind conditions, and underground utilities must be assessed BEFORE setup — not after the crane arrives.

Tag Line Rules Are Often Ignored

OSHA requires tag lines when rotation or drift of the load could create a hazard. Many lift directors overlook tag line length, material, and attachment rules.

Jib Deduction From Main Boom Capacity

When a jib is attached — even if not in use — the main boom capacity must be REDUCED by the published deduction weight in the load chart notes.

Wind Speed Affects Both Capacity and Operations

Operations must stop in high winds (typically 20–25 mph in-service). Wind load also affects the effective weight of large surface-area loads — often ignored on lift plans.
