Scope of Application
DIN 15063, the standard governing electric control systems for cranes, applies to the design, manufacturing, and inspection of electrical control equipment used across various crane types. Its scope covers general purpose bridge cranes and gantry cranes with a rated lifting capacity of 3.2 tons and above, as well as electric hoists of corresponding work classifications. For equipment operating under ambient temperatures ranging from -20°C to +45°C with relative humidity not exceeding 85%, compliance with this standard is mandatory. Applications involving corrosive gases, explosive dust, or high-temperature radiation require additional consideration of explosion-proof or heat-resistant standards alongside other relevant specifications.
In developing the technical standardization framework, the standards body accounted for both commonalities and distinct requirements across different crane categories, adopting a tiered, classification-based management approach. When implementing DIN 15063, manufacturers should first determine the product category and classification level, then select the corresponding technical requirements and inspection methods. This graded management structure ensures the standard's broad applicability while addressing the specific needs of diverse operating conditions. Kelude's engineering team has accumulated extensive hands-on experience in standard implementation and can provide precise guidance on standard application. For products destined for export overseas, manufacturers must also account for differences between this standard and international equivalents, ensuring compliance with both domestic requirements and the technical regulations of target markets.
Core Technical Parameters Comparison
DIN 15063 sets forth detailed and stringent requirements for the core technical parameters of crane electrical control systems. Regarding structural strength, the standard mandates that critical load-bearing components achieve a static strength safety factor of no less than 3.5 times the rated load and a fatigue strength safety factor of no less than 2.0 times. For material selection, all load-carrying members must be fabricated from high-strength low-alloy structural steel of Q345B grade (≈S355J2) or higher, with primary mechanical performance indicators conforming to GB/T 1591. The standard also specifies clear ranges for chemical composition, carbon equivalent control, and impact toughness, ensuring reliable fracture resistance even at low ambient temperatures.
Beyond these core parameters, DIN 15063 establishes explicit reliability requirements, stipulating a mean time between failures (MTBF) of no less than 5,000 hours under rated operating conditions and a design service life of at least 15 years. These reliability indicators require manufacturers to incorporate adequate safety margins and fatigue-resistant design principles from the initial design phase, leveraging refined structural analysis and design optimization to ensure safe and reliable operation throughout the equipment's lifecycle. Reliability verification is ultimately confirmed through systematic testing, including Type Tests and accelerated aging tests, complemented by advanced computational assessments such as finite element analysis and fatigue life prediction.

Safe Operation Requirements for Crane Electrical Systems
DIN 15063 sets clear requirements for the safe operation of electrical control equipment, mandating that user units establish a comprehensive equipment safety management system. All operators must complete professional training and hold the relevant certifications — untrained personnel are strictly prohibited from operating the equipment. A full safety inspection must be carried out before every use, with particular attention to abnormal wear, cracks, deformation, or other defects. During operation, operators must strictly follow the operating procedures, never exceed the rated working load, and avoid any unsafe practices. Any abnormality must be addressed immediately by stopping the machine, investigating, and documenting the incident for future reference.
For safety management system development, DIN 15063 encourages enterprises to adopt the PDCA (Plan-Do-Check-Act) continuous improvement cycle to steadily raise their equipment safety management standards. Companies should maintain complete equipment safety records covering installation & commissioning, daily operation, maintenance, and fault handling. Kelude offers standardized equipment safety management system development and operator training services to help enterprises strengthen their overall safety posture. In addition, regular safety emergency drills should be organized to improve operators' emergency response capabilities under unexpected conditions.
Inspection and Maintenance Intervals
Regular inspection and systematic maintenance are essential to ensuring the long-term safe operation of electrical control equipment. DIN 15063 provides detailed requirements on inspection and maintenance intervals and their scope. For routine maintenance, the standard requires operators to perform a visual inspection daily, focusing on visible wear, deformation, and cracks. For periodic inspection, the standard stipulates that a full inspection be conducted at least once a year, covering structural integrity, safety device functionality, and control system performance. All inspection results must be documented and archived as the basis for assessing the equipment's technical condition.
Beyond routine inspection and maintenance, DIN 15063 places special emphasis on post-overhaul and post-retrofit inspection requirements. After a major overhaul or significant technical retrofit, equipment must undergo a complete type test and factory acceptance test in accordance with new-equipment standards. Only when all technical indicators are verified to meet the standard's requirements may the equipment be returned to service. For aging equipment in service for more than 15 years, enterprises should organize a dedicated safety assessment covering structural fatigue life analysis, corrosion degree detection, and safety device performance testing. Based on the assessment results, a science-based equipment renewal plan should be developed to ensure that aging equipment is retired or upgraded in a timely manner once it reaches its design service life.
