CCO’s Lift Director certification for mobile cranes is a written-only credential: a Core examination of 40 questions in 60 minutes and a Mobile Cranes Specialty examination of 15 questions, taken alongside the corresponding operator and Rigger Level II requirements the handbook prescribes — with no practical examination at any point. Certification runs five years. PassProfessor’s Mobile Crane Lift Director program is in the works for the written examinations.

The mobile lift director is accountable for the lift as an event: not the crane’s operation, which belongs to the operator, and not the rigging, which belongs to the riggers, but the plan that binds crane, load, crew, and site into one defensible operation — and the authority to stop it. On mobile work that accountability is exercised in changing conditions: configurations change between picks, ground is rejudged at every setup, and the director’s value is precisely the independence of the role from the schedule. CCO’s credential formalizes a role ASME and OSHA texts assume exists; the written examinations test whether its holder can actually discharge it.
PassProfessor’s Mobile Crane Lift Director (MLD) program is in the works as part of the expanding PassProfessor catalog, organised on the written examination’s published domains so preparation follows the examination’s own architecture. This page states the credential’s verified facts — its examinations, its fees, its windows, and the component this program does not cover — exactly as the issuing body publishes them.
Which credential is this?
This page covers one credential only: the Mobile Crane Lift Director (MLD), issued by CCO (NCCCO). It is not a neighbouring designation, and the distinctions matter, because this family of credentials is deliberately granular — each designation certifies a defined machine, role, or function, and an employer or regulator asking for one is not asking for another. The facts table below is the credential’s identity card; the companion guide walks the route to it in full. Candidates should confirm, before any preparation begins, that this is the designation their employer, their site, or their licence actually requires — in this suite, the costliest preparation error is preparing thoroughly for the adjacent credential.
What will the program cover?
Timed, multiple-choice practice throughout. This credential’s written examination is a timed, multiple-choice sitting, and the program in the works is built to rehearse exactly that performance: full-length timed sets, domain sets weighted as the published outline weights them, and review organised by domain so a weak area is visible while there is time to repair it.
Handbook-first sourcing. Every syllabus decision in the program traces to the issuing body’s own publications — the candidate handbook, the written examination outline, and the published fee and policy record. The program teaches the examination CCO (NCCCO) actually administers, in the vocabulary its handbook uses.
The route around the test, taught honestly. Eligibility gates, companion examinations, windows, and validity periods are part of the program’s material, stated as the issuing body publishes them — including the components this program does not cover, named as such wherever they appear.
An independent program, plainly labelled. PassProfessor is not affiliated with CCO (NCCCO), is not endorsed by it, and reports nothing to it. The credential decision belongs to the issuing body alone.
The written-only boundary, stated plainly
This credential has no practical examination. Written examinations only — there is no practical examination in the Lift Director program. The Core Lift Director Examination contains 40 questions in 60 minutes; the Lift Director — Mobile Cranes Specialty Examination contains 15 questions (Lift Director Candidate Handbook, LDCH REV 06/23) PassProfessor preparation covers the Lift Director written examinations; the handbook’s companion requirements — the corresponding operator and Rigger Level II examinations, where they apply to a candidate — are separate CCO examinations with their own programs, and the companion written sittings are identified in the route section below so candidates can plan the full set.
What are the verified facts of the credential?
| Fact of record | Detail |
|---|---|
| Designation | Lift Director — Mobile Cranes; designation code MLD in the scope, in CCO’s Lift Director program |
| Certifying body | CCO — the National Commission for the Certification of Crane Operators (NCCCO) |
| Examination structure | Written examinations only — there is no practical examination in the Lift Director program. The Core Lift Director Examination contains 40 questions in 60 minutes; the Lift Director — Mobile Cranes Specialty Examination contains 15 questions (Lift Director Candidate Handbook, LDCH REV 06/23) |
| Companion requirements — read this first | The handbook also requires the corresponding operator examination and/or the Rigger Level II examination, unless the candidate already holds the relevant CCO certification in good standing — currently certified operators need not retake the operator examination, and certified Rigger Level II certificants need not retake that written examination |
| Examination fees | Third-party fees paid to CCO under its published fee schedule: $160 for the Core examination and $160 for each specialty examination |
| Eligibility | At least 18 years of age; pass the written examination(s); comply with CCO’s Substance Abuse Policy and Code of Ethics |
| Validity | Certification is valid for five years |
How does preparation map to the examination outline?
The published outline for this written examination organises the sitting as follows. Preparation in the program in the works is organised on the same domains.
| Examination domain | Weight / character |
|---|---|
| Site and Personnel — Core | Core domain |
| Crane and Load Knowledge — Core | Core domain |
| Lift Planning — Core | Core domain |
| Standards and Regulations — Core | Core domain |
| Mobile Cranes Specialty — Configurations and Charts | Specialty domain |
| Mobile Cranes Specialty — Direction in Practice | Specialty domain |
Site and Personnel — Core (Core domain). The lift director’s first material is the site and the org chart: ground and access, overhead hazards, the qualifications of every person on the lift team, and the director’s documented authority — including stop authority — within the site’s management structure. The Core examination tests this foundation identically for both specialties.
Crane and Load Knowledge — Core (Core domain). Directors do not operate, but they must know: crane configuration and chart literacy, load weight determination, rigging fundamentals, and the arithmetic of capacity margins. Core items ensure no candidate directs a lift whose numbers they cannot personally verify.
Lift Planning — Core (Core domain). The director’s central product is the plan: standard versus critical lift classification, the written plan’s required elements, pre-lift meeting conduct, communication structure, contingency and abort criteria, and the documentation that survives the lift. This is the Core domain both specialties build on.
Standards and Regulations — Core (Core domain). OSHA Subpart CC’s allocation of responsibilities, the ASME B30.5 and B30.3 frameworks as they apply to direction rather than operation, ASME P30 lift planning principles, and the regulatory meaning of the roles — operator, rigger, signalperson, assembly/disassembly director — the lift director coordinates.
Mobile Cranes Specialty — Configurations and Charts (Specialty domain). Mobile specialty items work the director’s mobile-specific material: configuration selection and verification, outrigger and crawler setups, pick-and-carry considerations, chart application across areas of operation, ground bearing and matting decisions, and assembly/disassembly interfaces with the A/D director’s duties.
Mobile Cranes Specialty — Direction in Practice (Specialty domain). Directing mobile work in practice: multi-crane and tandem lift direction, critical lift execution on mobile equipment, travelling and repositioning decisions between picks, weather limits for mobile configurations, and the director’s conduct when the site — production pressure included — pushes against the plan.
Who earns this credential?
Candidates are lift planners, crane supervisors, rigging foremen stepping into direction, and senior operators formalizing the role they already fill on critical picks. Employers pursuing documented critical-lift management — industrial, energy, and heavy construction owners increasingly require it contractually — supply much of the pool.
What is the route to the credential?
CCO’s route runs: meet the eligibility terms, pass the Core written examination and the Mobile Cranes Specialty written examination, and satisfy the handbook’s companion requirement — the corresponding operator examination and/or Rigger Level II examination, waived where the candidate already holds that CCO certification in good standing. Examinations may be taken in any order. There is no practical examination. Certification runs five years. This program prepares candidates for the Lift Director written examinations.
What makes this examination demanding?
The demand is integrative. The Core examination assumes operator-level crane knowledge and rigger-level rigging knowledge — the handbook’s companion requirements make that literal — and then tests the layer above both: classification, planning, personnel, and abort judgment. Candidates who direct lifts by presence and experience must demonstrate the documented version: plans with required elements, margins computed rather than felt, and stop decisions grounded in the standards the examination names.
An honest note on format
PassProfessor practice works in the format this examination uses — multiple-choice, timed at the examination’s pace. The issuing body does not release its examination items, and no provider can offer them. Practice results are a study gauge, not a prediction of a certification or licensing outcome, and the examination decision and the credential decision both belong to bodies other than PassProfessor.
How should you use this page while the program is in the works?
- Join the notify list today. Enrollment is not open yet, and the notify list is how you hear the moment it is. While you wait, read the exam guide — it walks the route, the outline domain by domain, the sitting itself, and a preparation plan in full.
- Confirm the designation before the syllabus. Read the ‘Which credential is this?’ section above twice if your background is in a neighbouring machine or role; in this suite, designations are atomic, and the wrong one is a wasted season.
- Plan the whole route, not only the sitting. The steps around the written examination — companion examinations, practical sittings this program does not cover, approval gates, and completion windows — have their own lead times, and candidates who start them during preparation do not lose a season to sequencing after a pass.
- Study from the primary documents alongside any preparation. The candidate handbook or licensing guidance and the published outline are the examination’s sources, and both are published for candidates.
Frequently asked questions
What is the Mobile Crane Lift Director (MLD) credential? It is the credential this page covers: Lift Director — Mobile Cranes; designation code MLD in the scope, in CCO’s Lift Director program. The mobile lift director is accountable for the lift as an event: not the crane’s operation, which belongs to the operator, and not the rigging, which belongs to the riggers, but the plan that binds crane, load, crew, and site into one defensible operation — and the authority to stop it. The issuing body is CCO (NCCCO).
Who issues the mobile lift director credential? CCO (NCCCO). That body writes or administers the examination, sets the requirements, and makes the certification or licensing decision. PassProfessor prepares candidates for the written examination and has no part in the decision.
What written examination must candidates pass? Written examinations only — there is no practical examination in the Lift Director program. The Core Lift Director Examination contains 40 questions in 60 minutes; the Lift Director — Mobile Cranes Specialty Examination contains 15 questions (Lift Director Candidate Handbook, LDCH REV 06/23)
Is there a practical or hands-on examination? There is no practical examination in this credential; its examination requirement is written only, as the facts table states.
What is the passing standard? CCO sets the passing standard for its examinations by criterion-referenced standard setting and reports each candidate’s performance by domain. This page states no percentage figure for the standard, because CCO does not publish it as a simple percentage for this designation — inventing one would misstate the record.
What does the examination cost? Third-party fees paid to CCO under its published fee schedule: $160 for the Core examination and $160 for each specialty examination Those are third-party fees owed to the issuing body — not PassProfessor charges. This page prints no PassProfessor price.
How long does the credential last? Certification is valid for five years
What will the PassProfessor program cover? The written examination named above — its published domains, its format, and its pacing — together with the certification or licensing route around it as the issuing body publishes it. Where the credential has a practical component, that component is not covered, and the program says so wherever the credential is described.
When will the PassProfessor program open? The program is in the works and enrollment is not open yet. Join the notify list on this page and you will be emailed when enrollment opens; the companion exam guide is available to read now for planning your preparation.
Is PassProfessor affiliated with CCO (NCCCO)? No. PassProfessor is an independent preparation provider and is not affiliated with CCO (NCCCO). Nothing in the program is reported to the issuing body, and completing preparation is not a step in the certification or licensing process.
