An apparatus for controlling a load handling device (16, 21) of an industrial vehicle including: a lift cylinder that is supplied with hydraulic oil at a flow rate determined by an operation amount of a lift lever as a load handling lever and lifts and lowers the load handling device (16, 21) at a speed determined by the flow rate of hydraulic oil supplied to the lift cylinder; and a tilt cylinder that is supplied with hydraulic oil at a flow rate determined by an operation amount of a tilt lever as a load handling lever and tilts the load handling device (16, 21) at a speed determined by the flow rate of hydraulic oil supplied to the tilt cylinder, the apparatus that controls the supply of hydraulic oil to the lift cylinder and the tilt cylinder comprising: a lifted height detector that detects a lifted height of the load handling device (16, 21); a tilt angle detector that detects a tilt angle of the load handling device (16, 21); a loading pump that pumps hydraulic oil from a hydraulic tank provided in the industrial vehicle and supplies the hydraulic oil to the lift cylinder and the tilt cylinder; a drive that drives the loading pump; and a controller that controls the flow rate of hydraulic oil supplied to the lift cylinder and the tilt cylinder, characterized in that when the forward tilt angle of the load handling device (16, 21) is greater than a first regulation tilt angle and the lifted height of the load handling device (16, 21) is higher than a predetermined reference height, the controller regulates the flow rate of hydraulic oil supplied to the lift cylinder, such that the lifting speed of the load handling device (16, 21) is reduced. a lift cylinder that is supplied with hydraulic oil at a flow rate determined by an operation amount of a lift lever as a load handling lever and lifts and lowers the load handling device (16, 21) at a speed determined by the flow rate of hydraulic oil supplied to the lift cylinder; and a tilt cylinder that is supplied with hydraulic oil at a flow rate determined by an operation amount of a tilt lever as a load handling lever and tilts the load handling device (16, 21) at a speed determined by the flow rate of hydraulic oil supplied to the tilt cylinder, the apparatus that controls the supply of hydraulic oil to the lift cylinder and the tilt cylinder comprising: a lifted height detector that detects a lifted height of the load handling device (16, 21); a tilt angle detector that detects a tilt angle of the load handling device (16, 21); a loading pump that pumps hydraulic oil from a hydraulic tank provided in the industrial vehicle and supplies the hydraulic oil to the lift cylinder and the tilt cylinder; a drive that drives the loading pump; and a controller that controls the flow rate of hydraulic oil supplied to the lift cylinder and the tilt cylinder, characterized in that when the forward tilt angle of the load handling device (16, 21) is greater than a first regulation tilt angle and the lifted height of the load handling device (16, 21) is higher than a predetermined reference height, the controller regulates the flow rate of hydraulic oil supplied to the lift cylinder, such that the lifting speed of the load handling device (16, 21) is reduced. a lifted height detector that detects a lifted height of the load handling device (16, 21); a tilt angle detector that detects a tilt angle of the load handling device (16, 21); a loading pump that pumps hydraulic oil from a hydraulic tank provided in the industrial vehicle and supplies the hydraulic oil to the lift cylinder and the tilt cylinder; a drive that drives the loading pump; and a controller that controls the flow rate of hydraulic oil supplied to the lift cylinder and the tilt cylinder, characterized in that when the forward tilt angle of the load handling device (16, 21) is greater than a first regulation tilt angle and the lifted height of the load handling device (16, 21) is higher than a predetermined reference height, the controller regulates the flow rate of hydraulic oil supplied to the lift cylinder, such that the lifting speed of the load handling device (16, 21) is reduced.
