Abstract:
The present disclosure provides a method for controlling a cooling fan-brake of construction equipment, including: generating a brake charging signal of a brake unit; charging hydraulic oil with a high flow rate in the brake unit and completing the charging of hydraulic oil; turning a loading valve of a cooling fan unit off and turning an unloading valve of the cooling fan unit on when the hydraulic oil is charged; 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.
