摘要： PROBLEM TO BE SOLVED: To easily provide an accurate value of a load weight on a load support means in a hydraulic lifter.
SOLUTION: In this method for measuring the load weight on the load support means in the hydraulic lifter of an industrial truck wherein pressure of a hydraulic fluid in a lift cylinder 10 is measured, wherein a reference curve expressing a relation between the load weight and hydraulic pressure is determined based on a plurality of measured values of the pressures by the known weight to store the reference curve, the method is provided with a following step: the load support means is lifted up in a short period according to the requirement of an operator or an automatic means to detect the load weight before a lifting-up and -down operation for the load and in the lifting-up and -down operation therefor, the plurality of measured values of the pressures is obtained during the lifting-up and -down of the load support means in the short period, a pair of average values of the pressure measured values is generated in each of lifting-up 14 and lowering 16, the third average value of the paired average values is generated in each of the lifting-up and the lowering, and the third average value is applied to the reference curve to determine the load weight.

摘要： PROBLEM TO BE SOLVED: To provide a braking device for an industrial truck automatically braking a vehicle independently of a normal braking operation when the erroneous operation of a vehicle occurs. SOLUTION: This braking device for an industrial truck comprises a hydraulic brake cylinder coupled to a working element and connected to at least one hydraulic brake connected to the wheel of the industrial truck through a brake line. The other hydraulic brake cylinder 26 is connected to the hydraulic brake line, and the second brake cylinder 26 is coupled to an electromagnet 44. In addition, the braking device comprises an emergency stop device feeding braking signals to the electromagnet 44 for operating the second brake cylinder 26. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an industrial truck having a highly reliable steering device allowing safe operation in different steering operation modes.
SOLUTION: This method is for steering the industrial truck. This device comprises a control unit having at least a steering control device 28 and a movement control device 30. The steering control device 28 has different steering operation modes for three or four steerable wheels, and these wheels are controlled with basic positions taken as start positions. Each of the steering operation modes controls the driving and/or the braking of the industrial truck by using a set of the movement parameters controlled with a basic position used as a start point and having at least one steering operation mode and a set in which the movement control device 40 is related to an actual steering operation mode.

摘要： PROBLEM TO BE SOLVED: To provide an improved reach forklift truck that can reduce the width of passage. SOLUTION: A battery for power supply to various driving means for the reach forklift truck is divided into two battery sections, which are each housed in a battery trough 40, 42. The battery troughs 40 and 42 are each supported on a wheel arm 22, 24 and by the wheel arm 22, 24. The positioning of the battery not in a cab part but on the wheel arms can substantially reduce the cab part. The reach forklift truck can thereby have a small turning radius to reduce the width of passage. COPYRIGHT: (C)2004,JPO
