The CCO Articulating Boom Crane with Winch (ABW) designation certifies operators of articulating boom cranes fitted with a winch – the knuckleboom machine whose lifting is done by wire rope over the boom tip. Its written examination is a single examination of 75 questions in 90 minutes, the longest in the articulating family, with technical knowledge weighted heaviest on wire rope, reeving, and winch work. Certification also requires a practical examination and runs five years. This program covers the written examination only.

What this designation certifies
Fit a winch to a knuckleboom and the machine gains a second lifting personality. The articulated boom still folds, reaches, and places; but now the load hangs from a wire rope run over the boom tip, which means the operator also works a hoist: reeving parts of line for capacity, choosing downhaul weight so the rope spools and falls correctly, watching rope condition against formal removal criteria, and guarding the tip against two-blocking. CCO examines that combination as its own designation – ABW – with the longest written examination in the articulating family, 75 questions, and a technical domain that carries wire rope and winch material found nowhere else in the family. The designation is separate from ABC, not an endorsement of it. This program covers the written examination only.
What separates the winch machine is that its load path runs through a rope, and ropes introduce variables the bare hook machine never meets: line pull against parts of line, rope stretch and rotation, drum spooling, the behaviour of an unloaded hook that must be weighted to fall, and a tip that can be two-blocked by the operator’s own hoist function. The operator’s competence is therefore double: the articulated geometry of the boom and the hoisting mathematics and rope craft of a winch. The examination’s structure – operations and technical knowledge together at roughly 70% of the sitting – reflects that doubling, and candidates who arrive as knuckleboom operators with casual rope habits meet the designation’s real subject in the technical domain.

What the written examination covers
Operations and technical knowledge share the lead at approximately 35% each. Operations examines delivering and placing loads with a winch line: hoisting and lowering control, load handling on a rope, remote operation, and the delivery cycle. Technical knowledge is where ABW earns its separate existence: wire rope construction, grades, and breaking strength; inspection and replacement criteria; multi-part reeving and the line pull arithmetic it produces; downhaul weight selection; winch and drum behaviour; and two-block prevention – alongside the articulated machine’s hydraulics and stability systems. Site and setup takes 13%, and manufacturers’ load charts 17%, read for a machine whose configurations include its rope arrangements.
Site and Setup — ~13%
The family’s smallest site share, reflecting a machine whose setup follows the articulating pattern: stabiliser placement and ground, position for the pick and the lower, swing and reach room, and overhead checks. The winch adds its own setup items – the space and anchoring arrangements a long lower requires, and the ground organisation of rope, rigging, and downhaul equipment around the truck.
Operations — ~35%
Operations examines working the winch machine: hoisting and lowering under control through the articulated geometry, load handling on a rope – including the swing and rotation behaviour rope introduces – remote control discipline, coordinating boom sections with hoist function, and the delivery and placement cycle end to end. Combined-function judgement, boom and winch together, is the domain’s centre.
Technical Knowledge — ~35%
The designation’s signature domain, jointly the outline’s heaviest: wire rope construction, classification, and breaking strength; inspection regimes and replacement criteria; multi-part line, reeving arrangements, and line pull; downhaul weight selection and behaviour; winch, drum, and spooling; two-block causation and prevention; and the articulated machine’s hydraulics, geometry, and protection systems beneath it all. No other articulating designation examines rope at this depth.
Manufacturers’ Load Charts — ~17%
Charts for the winch machine state capacity against radius and configuration, and the rope arrangement interacts with them: the chart domain examines reading capacity for the configuration in use, the deductions and conditions the manufacturer attaches, and the relationship between parts of line, line pull limits, and the chart’s numbers. A candidate can reeved correctly and still overload the chart, or read the chart correctly and exceed the rope – the domain examines both failures.
Who this certification serves
Winch-fitted knucklebooms work where loads must be lowered as precisely as they are placed: utility and pole work support, precast and vault setting, wellhead and plant maintenance, sign and structure work, and the heavier end of the delivery trades where the pick exceeds what the bare hook geometry serves. Their operators are riggers as much as drivers – the reeving decision is made at the truck, by the operator, for each heavy pick. Employers read ABW as examined evidence across both crafts: the articulated boom and the hoist. The designation’s separateness protects that reading: an ABW credential is not inferred from ABC, and fleets that run winch machines staff them accordingly.
The written route, in order
One written examination – 75 multiple-choice questions in 90 minutes – and one practical examination on an articulating boom crane with winch, passed within 12 months of each other, produce a five-year certification. There is no Core examination in the articulating family. Results issue under CCO’s criterion-referenced scoring; CCO publishes no percentage passing standard. CCO’s written examination fee is $210 under the fee schedule effective January 1, 2024. Candidates holding ABC should note plainly: ABW is a full separate designation with its own written and practical examinations, not an upgrade, an endorsement, or a paperwork conversion of the hook machine’s credential.
What makes this examination demanding
Seventy-five questions is the family’s longest sitting, and its technical block is the family’s deepest: rope construction and breaking strength, replacement criteria stated precisely, reeving configurations and their line pulls, downhaul selection, and two-block causation. The demanding skill is rope literacy at examination precision – knowing not merely that a rope is worn but which criterion, stated in the standard’s terms, condemns it; not merely that more parts of line lift more, but what the resulting line pull is and what it does to the winch, the rope, and the chart. Hook-machine experience covers the boom half of this sitting and leaves the rope half untouched.
The credential at work
The certified winch operator’s working value is the controlled lower and the engineered pick: vaults eased into excavations, heavy units landed on bolts, loads held plumb on a rope while the articulated boom walks them into place. The designation certifies the habits behind that work – reeving chosen by arithmetic, downhaul treated as part of the rigging, rope inspected against criteria rather than impressions, and the tip watched as a two-block candidate on every hoist. In a family of three designations, ABW is the one employers reach for when the job description mentions the winch, and its separateness is what makes that reach reliable.
What the PassProfessor program will cover
Practice in the examination’s own shape. The CCO Articulating Boom Crane with Winch written examination is a multiple-choice written examination, and the program in the works practises in that shape throughout: timed sets at the examination’s pace, single-best-answer items, and domain sets matched to the published outline’s weights. Candidates should arrive having already made their pacing mistakes in practice.
Written from the primary sources. The program is written from the outline in the CCO Articulating Crane Operator Candidate Handbook (REV 09/23) and the standards that handbook’s reference list names – the same documents the examination is built from. Where this designation’s rules differ from the neighbouring designations, and on manufacturers’ load charts they do, the program teaches this designation’s rule and names the difference, rather than teaching a suite-wide average.
The whole candidate, not only the test-taker. Around the item practice, the program carries the certification route as CCO publishes it – eligibility, the written examination, the practical examination this program does not cover, and the five-year certification period – because a written examination is a means to a certification, and candidates plan better when the destination is mapped.
Preparation only. This is preparation for a written examination administered by CCO. It offers no preparation for the practical examination. PassProfessor is not affiliated with CCO (the National Commission for the Certification of Crane Operators, NCCCO) or with OSHA, no completion of this program is reported to CCO, and nothing in the program substitutes for any step in the certification process.
Tell me when enrollment opens. The CCO Articulating Boom Crane with Winch (ABW) program is in the works and enrollment is not yet open. Leave an email address and PassProfessor will write to you when the program is ready — and only about this program. No date is promised, because the program will open when it meets the standard described above, not before.
Frequently asked questions
Does this program cover the CCO practical examination?
No. It prepares candidates for the ABW written examination. Certification also requires a practical examination on an articulating boom crane with winch, for which this program offers no preparation and no hands-on component.
I hold ABC. Is ABW just an add-on?
No. ABW is a full, separate designation with its own written examination – 75 questions, against ABC’s 65 – and its own practical examination. It exists because the winch adds a body of knowledge, wire rope and hoisting work, that the ABC examination does not carry.
Why is the ABW examination longer than ABC’s?
Because of the rope. The winch designation’s outline adds wire rope construction and strength, inspection and replacement criteria, reeving and multi-part line, downhaul weights, and two-block prevention to the articulating core – material concentrated in a technical domain weighted at about 35%.
How long is ABW certification valid?
Five years, under the current CCO Articulating Crane Operator Candidate Handbook, which also sets recertification requirements including experience-based provisions.
What does CCO charge for the written examination?
Per the CCO fee schedule effective January 1, 2024, the ABW written examination fee is $210 – a third-party fee charged by CCO for its own examination.
Is there a percentage passing standard?
CCO publishes none for this written examination; results are determined under CCO’s criterion-referenced scoring. Percentages quoted elsewhere are not CCO’s.
Is PassProfessor affiliated with CCO?
No. PassProfessor is an independent preparation provider, not affiliated with CCO (the National Commission for the Certification of Crane Operators, NCCCO) or OSHA. The program confers no certification and reports nothing to CCO.
What is a downhaul weight, in examination terms?
The weight hung on the line to make the unloaded hook and rope travel down and spool properly when there is no load – sized to the rope and the boom configuration. Selecting it, and understanding what too little or too much does, is examined material unique to this designation’s technical domain.
What is two-blocking, and why does this designation stress it?
Two-blocking is the hook block or downhaul being hoisted into the boom tip, damaging rope, tip, or both. A winch machine hoists actively, so the risk is operational rather than incidental; prevention – devices, awareness, and hoist discipline – is named knowledge in this designation’s outline.
Does the truck or crawler mounting change the designation?
No. The articulating designations apply to truck- and crawler-mounted machines alike, as the handbook states. The winch, not the mounting, makes this designation.
