| Product Definition | EN 14985:2012, Cranes — Slewing Jib Cranes | A fixed or mobile crane with a slewing arm that moves a hoist or trolley within a defined working envelope. | Wall-mounted, floor-mounted, column-mounted, mobile-base, or workstation configurations. | Approved general arrangement drawing showing the column, boom, pivot, hoist, trolley, and operating radius. |
| Structural Design | EN 13001 series and ISO 8686-1 | The structure should be designed for rated load, self-weight, dynamic effects, horizontal forces, wind conditions where applicable, and fatigue. | Boom length, lifting height, outreach, headroom, load spectrum, and installation environment. | Design calculations, load cases, material specifications, weld details, and signed engineering approval. |
| Duty Classification | ISO 4301-1 | The crane and hoist should be selected according to expected operating cycles, load spectrum, average operating time, and frequency of use. | Light workshop service, regular production handling, frequent operation, or higher-cycle industrial service. | Duty-class calculation based on daily lifts, operating hours, load distribution, and expected design life. |
| Rated Capacity | Manufacturer design documentation and applicable local regulations | Rated capacity must be clearly marked and must not be exceeded, including the weight of lifting accessories and below-the-hook equipment. | Capacity, load-hook position, tandem lifting requirements, and overload protection settings. | Nameplate, capacity chart where required, calibrated load-test certificate, and overload-limiter test record. |
| Hoist and Lifting Mechanism | EN 14492-2 or ASME B30.16, where applicable | The hoist should include a suitable brake, limit devices, load chain or wire rope system, guarding, and controls appropriate to the selected duty. | Electric chain hoist, wire-rope hoist, manual hoist, variable-speed lifting, pendant, radio, or remote control. | Hoist technical file, brake test, upper and lower limit test, control-function test, and spare-parts list. |
| Electrical Safety | IEC 60204-32, Safety of Machinery — Electrical Equipment of Machines — Requirements for Hoisting Machines | Electrical circuits should be selected for the site voltage, frequency, earthing system, control method, and environmental conditions. | Voltage and frequency, pendant length, festoon or cable reel, emergency stop, inverter control, and enclosure protection. | Wiring diagram, insulation-resistance test, protective-earth continuity test, functional test, and component certificates where required. |
| Welding and Fabrication | ISO 3834 series; ISO 9606-1 for welder qualification | Load-bearing welds should be produced using qualified procedures and suitably qualified welders, with controlled materials and traceability. | Steel grade, plate thickness, reinforcement details, bolt pattern, base plate, and mounting arrangement. | Welding procedure specifications, welder qualifications, material certificates, weld inspection reports, and non-destructive testing records when specified. |
| Surface Preparation and Coating | ISO 8501-1 and ISO 12944 | Surface cleanliness, coating system, dry-film thickness, and corrosion category should match the indoor, outdoor, humid, coastal, or chemical environment. | Primer and topcoat system, color, galvanizing, high-build coating, corrosion category, and additional weather protection. | Surface-preparation record, coating-product data sheets, ambient-condition log, and dry-film-thickness measurement report. |
| Pivot and Slewing Assembly | Approved engineering drawings and applicable crane design calculations | The pivot, bearings, stops, and support structure should safely withstand vertical load, overturning moment, horizontal forces, and repeated rotation. | Manual or powered rotation, rotation angle, mechanical stops, locking device, bearing arrangement, and outdoor sealing. | Bearing specifications, bolt-torque records, rotation test, stop-function test, and dimensional inspection report. |
| Load Testing | Applicable national regulations and contract test procedure | Testing should confirm lifting, lowering, braking, trolley travel, slewing, emergency stop, limit devices, and structural stability under the agreed test plan. | Factory acceptance test, witness inspection, site commissioning test, and customer-specific acceptance criteria. | Calibrated test-weight record, test procedure, signed inspection checklist, photographs, and nonconformity closure report. |
| Installation Requirements | Site engineering requirements and local lifting-equipment regulations | The supporting floor, wall, column, or foundation must be verified for vertical reactions, shear, overturning moment, anchor forces, and installation clearances. | Base plate dimensions, anchor arrangement, foundation design, wall brackets, column extensions, and restricted-headroom installation. | Foundation or support calculations, anchor-bolt specifications, installation drawings, torque records, and site acceptance report. |
| Documentation Package | ISO 9001:2015 quality-management principles | A complete technical file should allow the buyer to verify design assumptions, manufacturing quality, testing, installation, and future maintenance needs. | Language, document format, inspection-plan content, spare-parts scope, maintenance schedule, and training materials. | Drawings, manuals, certificates, inspection plans, test records, parts lists, maintenance instructions, and final data book. |
| Buyer Comparison Criteria | Contract specification and applicable destination-country legislation | The preferred supplier should demonstrate compliance with the agreed design basis rather than relying only on general product descriptions or catalog ratings. | Total cost of ownership, delivery scope, commissioning support, warranty terms, training, service response, and spare-parts availability. | A signed technical compliance matrix showing each required parameter, deviation, document reference, and approval status. |
