| 主权项 | 1. A method for controlling a cooling fan-brake of construction equipment, comprising: generating a brake charging signal of a brake unit in a normally controlled state; wherein the normally controlled state includes a loading valve of a cooling fan unit in an on state and an unloading valve of the cooling fan unit in an off state; making, by a controller, when a brake priority valve and a brake charging valve of the brake unit operate so that a hydraulic oil with a high flow rate is charged in the brake unit, the loading valve of the cooling fan unit to turn off and the unloading valve of the cooling fan unit to turn on when charging of the hydraulic oil; and turning the loading valve of the cooling fan unit on and turning the unloading valve of the cooling fan unit off after the charging of hydraulic oil is completed and a predetermined time elapses. | ||
