TS ISO 7296-2

TS ISO 7296-2 is a standard for graphical symbols used on operator controls and other displays on mobile cranes. It addresses the visual language that helps operators recognize functions quickly and consistently, with the technical base of the subject tied to the mobile crane definition given in ISO 4306-2.

Why graphical symbols matter on mobile cranes

Mobile cranes are machines that can be moved from one worksite to another and operated through a dense set of controls. In that environment, symbols act as a crucial interface layer for functions such as lifting, boom movement, slewing, stabilizing and other operator actions. From a general technical perspective, graphical symbols do not replace all written labeling, but they reduce the problems created by language differences, limited panel space and the need for fast recognition in operational settings.

What this standard covers

• Graphical symbols intended for operator controls on mobile cranes.
• Related symbols used on other displays and marking surfaces.
• Use aligned with the mobile crane class defined in ISO 4306-2.
• Technical terminology connected to legibility, distinction and functional recognizability of symbols.

This listing represents a withdrawn edition of TS ISO 7296-2, so its value is as historical technical documentation for the standardized presentation of mobile-crane symbols. The central idea is the creation of a common visual language for machinery operation and human-machine interaction; however, the exact symbols included, any exclusions, and the detailed drawing rules can only be confirmed from the full text.
