Abstract: An apparatus for controlling a load handling device of an industrial vehicle is provided. The load handling device includes a mast assembly and a load handling attachment attached to the mast assembly. The apparatus includes a tilt angle detector that detects a tilt angle of the mast assembly, a controller that regulates a lifting speed of the load handling attachment, and a determination device that determines whether or not the load handling attachment is being lifted off the ground. When the determination device determines that the load handling attachment is being lifted off the ground, the controller permits the load handling attachment to be lifted at a speed faster than the regulated lifting speed.

Abstract: An apparatus for controlling a load handling device of an industrial vehicle includes a lifted height detector that detects a lifted height of the load handling device, a tilt angle detector that detects a tilt angle of the load handling device, a loading pump that pumps hydraulic oil from a hydraulic tank in the industrial vehicle and supplies the hydraulic oil to a lift cylinder and a 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. When the forward tilt angle of the load handling device is greater than a first regulation tilt angle and a lifted height of the load handling device is higher than a predetermined reference height, the controller regulates the flow rate of hydraulic oil supplied to the lift cylinder.

Abstract: A controlled cooling apparatus for a wire rod coiled into loops immediately after hot rolling. The coiled wire rod is transported with the loops laid substantially flat with a space of a given pitch from one another on a cooling bed. Nozzles are provided to project a cooling fluid such as forced air from below the cooling bed at an angle of from 40.degree. to 140.degree. with respect to the plane of the cooling bed to cool the coiled wire during its transportation. The nozzles are open in a transverse direction of the cooling bed with a nozzle opening area ratio of from 0.8 to 1.2, to provide uniform distribution of the cooling fluid in the transverse direction, whereby uniform cooling can be accomplished to minimize the variation in the cooling rates at densely overlapped loop portions and at sparsely overlapped loop portions.
