摘要： In a display system in an excavator, a position of an upper boundary line and a position of a lower boundary line are calculated. The upper boundary line indicates a height of a top of a cross section of a display object surface. The lower boundary line indicates a height of a bottom of the cross section of the display object surface. When the current position of the excavator is between the upper boundary line and the lower boundary line, a predetermined reference point of a display range is set to a predetermined position between the upper and lower boundary lines. When the current position of the excavator is above the upper boundary line, the reference point is set above the predetermined position. When the current position of the excavator is below the lower boundary line, the reference point is set below the predetermined position.

摘要： A calculation unit of a hydraulic shovel display system sets a predetermined display range displayed as a guidance picture for land shape data. The guidance picture shows a cross section of a target surface included in a display range as seen from a side of a main vehicle body, and a current position of the hydraulic shovel. The calculation unit calculates a position of a start point nearest the main vehicle body and a position of an end point set apart from the start point by a maximum reach length of the work machine in the cross section of the target surface as seen from the side based on land shape data, work machine data and a current position of the main vehicle body. The calculation unit calculates a predetermined reference point of the display range based on the positions of the start point and the end point.

摘要： Provided is a method for fabricating a stepped forged material that can realize a uniform microscopic structure in both the large diameter flange portion and the small diameter shaft portion. This method for fabricating a stepped forged material comprises the following steps: a step for obtaining a primary forged material in which an austenite stainless steel billet is heated to 1000-1080° C., and, without any further heating, the material is forged by means of reciprocal forging into a round rod having along the entire length thereof a forging ratio of 1.5 or greater; a step for obtaining a secondary forged material, that forms the large diameter flange portion and the small diameter shaft portion, in which without reheating, the small diameter shaft portion is formed by means of reciprocal forging at a temperature where the surface temperature of the primary forged material never falls more than 200° C. lower than the abovementioned material heating temperature and the forging is completed before the surface temperature of the final forged portion falls more than 300° C. lower than the abovementioned heating temperature; and a step for performing a solution heat treatment in which the secondary forged material is heated to 1040-1100° C. for 30 minutes or longer.
