| Rated load and coil range | Specify the maximum coil mass, minimum and maximum coil diameter, coil width, and any load-handling attachment mass. Capacity is a project-specific design value. | Check that the rated capacity covers the coil and tooling together, and request the proposed load distribution and operating limits. |
| Coil support and retention | Coil carts commonly use a V-shaped saddle or other shaped support to locate round coils. Support geometry depends on coil dimensions and handling orientation. | Confirm saddle angle, contact surface, coil-centering method, and whether restraints are needed for travel, stopping, or uneven floors. |
| Travel path and guidance | Transfer carts may be rail-guided or designed for floor travel. Rail layout, route length, curves, crossings, and stopping locations affect the design. | Provide a dimensioned site layout and verify route compatibility, clearances, stopping accuracy, and the required floor or rail capacity. |
| Power supply | Available configurations can include battery power, cable-reel power, or conductor-rail power. Each has different infrastructure and operating requirements. | Confirm site voltage and frequency, charging or cable arrangements, duty cycle, travel distance, and the safe routing of power equipment. |
| Drive, speed, and duty cycle | Drive configuration and operating speed should be matched to the load, route, starts and stops, and number of operating cycles. | Ask for the design duty cycle, acceleration and braking behavior, travel speed under load, and any operating restrictions. |
| Controls and safety functions | Controls may include pendant or remote operation, emergency stops, warning devices, and travel-limit or obstacle-detection features, depending on the design. | Review the risk assessment, control-system description, emergency-stop locations, operator visibility, and site-specific safety requirements. |
| Structural and electrical documentation | Relevant references may include ISO 12100 for machinery risk assessment and IEC 60204-1 for electrical equipment of machinery. Applicability depends on the project and jurisdiction. | Request drawings, calculations, wiring diagrams, operating instructions, and a list of standards applied to the specific cart. |
| Welding and quality management | ISO 3834 addresses quality requirements for fusion welding of metallic materials; ISO 9001 specifies requirements for quality management systems. | Check the scope and validity of any certificates, whether they cover the relevant facility and work, and what inspections and records are supplied. |
| Export and site acceptance | Shipping, installation, commissioning, documentation, and conformity obligations vary by destination and project scope. | Agree on delivery terms, installation responsibilities, local conformity requirements, acceptance tests, training, spare parts, and after-sales support before order placement. |
