Abstract

Panel (11) has two rows of lamps activated depending on pressures in hydraulic cylinders operating two or more pivotable arms. More lamps are lit as the pressure increases and the panel indicates when a maximum permitted pressure is exceeded. The panel shows a stylized silhouette crane symbol (13) with two inclined cylinder symbols and lamp symbols (16-19) placed in relation to the cylinder symbols to enable distinction between the cylinders.
