The invention discloses a pure electric off-highway mining dump truck double hydraulic pump power take-off mechanism which comprises a power take-off motor and two hydraulic pumps, and the two hydraulic pumps are connected to the two ends of the power take-off motor respectively. A rotating shaft of the hydraulic pump is rigidly connected with a rotating shaft of the power take-off motor; one of the two hydraulic pumps is a steering pump, and the other hydraulic pump is a lifting and disc braking double pump. The invention further discloses a power take-off method for the double hydraulic pumps of the pure electric off-highway mining dump truck. The power takeoff device solves the technical problem that power takeoff is conducted on two high-power hydraulic pumps at the same time in a narrow space.
