1. Method for signalling the loading and overloading of hydraulic loading platforms, booms, cranes and especially fork-lift trucks, in which the pressure in each of the lifting cylinder and the tifting cylinder is detected by pressure sensors, converted into electrical signals and, optionally after being amplified converted into optical and/or acoustic signals, characterized in that each of the electrical signals produced by the pressure in the lifting cylinder and the tilting cylinder is supplied to a series of light-emitting diodes, the individual light-emitting diodes in which respond to a specific electrical value produced by the particular pressure, the number of light-emitting diodes that light up increasing as the pressure increases and an optical and/or acoustic signal being triggered when a specific number of lit-up light-emitting diodes is exceeded. |
