Crane Operator Training Requirements Per ISO 23813:2018
ISO 23813:2018, "Crane Operator Training Requirements," is the standardized specification for crane operator training. It defines the theoretical training, practical training, assessment and certification, and continuing education requirements for operators of all crane types, with the goal of enhancing operator safety awareness and skill levels through a systematic training system.
Training System and Classification
ISO 23813:2018 structures crane operator training into three tiers: foundational operator training (for operators new to the role, covering common crane types such as tower cranes, bridge cranes, and mobile cranes), specialized operator training (advanced training for specific crane models or special working conditions, such as ultra-large tonnage mobile crane operation, luffing jib tower crane operation, and port container crane operation), and advanced competency training (for experienced operators, covering safety management and emergency response).
The standard requires the training system to include two core modules: theoretical learning (safety regulations, mechanism principles, parameter understanding, and signal communication) and practical training (simulator training and hands-on equipment operation). Theoretical training must comprise no fewer than 40 hours, and practical training no fewer than 80 hours (with simulator training capped at 40 hours). Training plans should be tailored to each operator's experience level and target crane type, and training providers must hold appropriate certification and have the necessary training facilities and equipment.
Theoretical Training Curriculum
The standard sets out a clear curriculum framework for theoretical training: fundamentals of lifting appliances (crane types, structures, and working principles, 10%); safety operating procedures (pre-lift inspections, lifting operation regulations, and emergency handling, 25%); relevant standards and regulations (ISO standard system, local regulations, and industry codes, 15%); load and stability (load calculation, stability assessment, and load moment limiter (LML) usage, 20%); crane signaling and communication (hand signals, whistle signals, and wireless communication procedures, 15%); and accident case analysis (typical accident causes and preventive measures, 15%).
Theoretical training materials must be certified standard materials, with content updates required at least every two years. Each theoretical session should be followed by an in-class test (multiple-choice and short-answer questions, with a passing threshold of ≥80%). Upon completion of the theoretical training, a comprehensive closed-book examination is administered (minimum duration: 2 hours), and the results remain valid for two years, after which operators must undergo refresher training and re-certification. The standard also specifies classroom facility requirements, including multimedia teaching equipment, simulation-based teaching systems, and standard illustrated materials.
| Training Module | Content | Proportion | Training Hours | Assessment Method |
|---|---|---|---|---|
| Machinery Fundamentals | Type/Structure/Principle | 10% | 4 | In-Class |
| safety regulations | Operation/Emergency/Inspection | 25% | 10 | theoretical examination |
| Standard Regulations | ISO/National/Industry | 15% | 6 | theoretical examination |
| Load Stability | Calculation/Stability/Torque | 20% | 8 | practical assessment |
| signal communication | Hand Signals/Whistle Signals/Radio Communication | 15% | 6 | practical assessment |
| accident case | Analysis/Preventive Measures | 15% | 6 | Written Report |
Practical Training and Assessment
The standard requires that practical training be conducted at certified training facilities equipped with at least two training cranes of different models — simulator training may supplement initial phases but cannot fully replace hands-on operation on actual equipment. Practical training covers daily inspection of the equipment (overall machine condition, safety devices, hydraulic and electrical system checks), basic operating skills (independent and combined motions including hoisting, lowering, slewing, luffing, and traveling), lifting operations (spot positioning, obstacle clearance, heavy-load handling, and precision micro-adjustment), and emergency procedures (emergency stop, power-loss release, and fault elimination).
Practical assessment uses an itemized scoring system — each operation has a defined pass threshold (e.g., spot positioning accuracy requires a placement deviation of ≤100 mm within a 500 mm diameter target), with an overall score of ≥80 required to pass. Assessments are conducted by independent examiners (not the training instructors) and recorded on video throughout. Certified operators must undergo refresher training and re-assessment every 2 years, with refresher content focused on updated standards, new procedures, and recent accident case studies. The standard also requires training institutions to maintain trainee records — training logs, assessment scores, operating experience, and incident reports must be archived for a minimum of 5 years.
Instructor Qualifications and Facility Certification
The standard sets clear requirements for training instructors — practical instructors must hold an operating certificate for the target crane model and have at least 5 years of hands-on operating experience. Theoretical instructors must hold a college degree or higher in a relevant engineering discipline, or possess a mid-level or above technical title. Practical instructors must complete a minimum of 200 hours of teaching methodology training and obtain an instructor certification. Each instructor may supervise no more than 4 trainees during practical sessions and 20 trainees during theoretical instruction.
Training institutions must obtain nationally or industry-recognized certification for their training programs — training facilities must meet safety requirements (adequate space, separation from work areas, and emergency evacuation access), training equipment must be well-maintained (within valid inspection periods with all safety devices fully functional), and management systems must be comprehensive (training plans, trainee records, equipment management, and safety contingency plans). Kelude provides crane operator training course development and technical support services for its partners, with training systems designed in accordance with ISO 23813:2018.

Frequently Asked Questions
Q: Which crane types are covered by ISO 23813:2018?
A: The standard covers operator training for tower cranes, bridge cranes, gantry cranes, mobile cranes, and jib cranes. Basic operating procedures are transferable across crane types, but type-specific training must be conducted on the actual equipment. Training programs should be tailored to the operator's target crane configuration.
Q: How many training hours are required for theoretical and practical instruction?
A: Theoretical training requires a minimum of 40 hours (including safety regulations 25%, load stability 20%, signal communication 15%, etc.), while practical training requires at least 80 hours (with simulator training capped at 40 hours). Total training time must reach 120 hours or more, and at least 40 hours of hands-on training must be completed on an actual crane.
Q: What is the certificate validity period and refresher training requirement?
A: Operator certificates are valid for 2 years. Before expiration, operators must complete refresher training (minimum 24 hours, covering updated procedures and recent accident cases) and pass the refresher assessment. Operators who fail to complete refresher training for two consecutive cycles must retake the full training program.
Q: Does Kelude Heavy Industry offer operator training services?
A: Kelude Heavy Industry provides partners with crane operator training system development and technical support in accordance with ISO 23813:2018, including training course design, instructional material development, simulator configuration, and assessment system setup.
