The invention provides an emergent steering system for engineering machinery. The emergent steering system comprises an oil tank, a steering pump, a gear pump, a one-way valve, a full-hydraulic steering gear, a steering oil cylinder, a three-way valve and a radiator motor. When the steering pump is broken down, the emergent steering system can communicate the gear pump with the full-hydraulic steering engine through the three-way valve to directly drive equipment to an appointed maintenance point under the condition of not using a tractor without influencing the construction of other equipment, and the equipment also can construct for a short time; and as the gear pump is only used for supplying oil to the radiator motor under the normal condition, when the steering pump is broken down, the gear pump supplies the oil to the full-hydraulic steering engine, the mode dose not increase the equipment manufacturing cost and cause the unnecessary waste, and the operation is simple.
