Abstract
The issue is to show displayed items on a display device of a cargo-handling vehicle, where only a display device having a small display space can be used, so that operations accompanying the operating sequence of the cargo-handling vehicle can be performed. The device has a tilt angle sensor, which detects forward tilt or backward tilt by a mast provided at the front of the cargo handling vehicle, a hydraulic pressure sensor, which measures the supply hydraulic pressure to a lift cylinder that is provided on the mast and raises and lowers a fork, and a calculation unit, which converts the cylinder supply hydraulic pressure detected by said hydraulic pressure sensor to the weight of the cargo loaded on the aforementioned fork. A selection display area is also provided, which selectively displays the tilt angle and the weight in the same location outside of the vehicle speed display area. When the vehicle's power is turned on and the tilt angle sensor detects forward tilt or backward tilt continuing for a predetermined period of time when the aforementioned mast is tilting forward or tilting backward, the tilt angle is displayed. When the application of pressure in a direction to ra…
