Abstract

The invention relates to a device and a method to ensure the steerability of an industrial truck that has a hydraulic steering system. The invention includes at least one gas generation cartridge (8) and a device (16) to activate the generation of the gas. The invention teaches that energy is available in an emergency for the hydraulic circuit of a hydraulic steering system. On the side of the gas generation cartridge (8), when there is a need to supply energy to the hydraulic circuit, pressure is increased which can then be transmitted to the hydraulic medium. The invention makes available an advantageous emergency power supply system for a hydraulic steering system of an industrial truck.
