| description | The invention relates to the field of hydraulic control of engineering machinery, and discloses a hydraulic control system and the engineering machinery. The pilot loop comprises a pilot control loop and a pilot self-heating loop which are arranged in parallel, a power valve is arranged in the pilot self-heating loop, and pilot hydraulic oil passing through the power valve can be heated; the controller is configured to obtain the initial pilot oil temperature of the pilot hydraulic oil in the initial starting state; under the condition that the initial pilot oil temperature is smaller than the first set oil temperature; and a pilot self-heating loop is started to heat pilot hydraulic oil. According to the hydraulic control system and the engineering machine, the oil temperature of the pilot oil way can be accurately increased in a cold working environment, and stable operation of the engineering machine is guaranteed.
