TS ISO 7296-1

TS ISO 7296-1 addresses the graphic symbols used on crane controls, together with the colour convention for control buttons and signal lamps. In practical terms, it belongs to the technical language of human-machine interfaces, where clear visual coding helps operators recognize functions quickly and consistently.

Why graphic symbols matter on crane controls

Cranes involve many distinct motions and functions, so the control layout must communicate meaning efficiently. Graphic symbols provide function labels that do not depend on written wording alone. In general technical context, this improves consistency across different user groups and supports faster recognition of commands, especially where language differences or limited visibility may be factors.

According to the supplied scope, this standard covers general graphic symbols for crane controls and indicates the colour of control buttons and signal lamps. That means the meaning of a control device is carried not only by its mechanical position but also by its visual coding. This distinction matters because a button command and a lamp status indication serve different roles in the same control system.

Technical boundaries of the document

• General graphic symbols used on crane control interfaces
• Colour convention for control buttons
• Colour convention for signal lamps
• Visual coding aimed at crane operator controls

The document focuses on harmonizing the visual sign system used in crane controls. In practice, standards of this kind support training, operational consistency and quicker identification of control elements. For this record, the scope is limited to general symbols and colour indications; broader machine design requirements or detailed performance specifications should not be assumed.
