|20130253759||WORK MACHINE - a work machine with a boom that can be derricked, includes: a first derricking angle detector that detects a derricking angle of the boom at a base end of the boom; a second derricking angle detector that detects a derricking angle of the boom at a front end of the boom; a first flexible volume acquisition part that acquires a flexible volume of the boom based on a detected angle by the first derricking angle detector and a detected angle by the second derricking angle detector; a second flexible volume acquisition part that acquires a flexible volume of the boom based on the detected angle by the first derricking angle detector; and a switching part that switches between acquisition of the flexible volume of the boom by the first flexible volume acquisition part and acquisition of the flexible volume of the boom by the second flexible volume acquisition part.||09-26-2013|
|20130013144||PERFORMANCE LINE DISPLAY UNIT - A performance line display unit includes an imaging device which is attached near a leading end of an extensible boom provided on a rotation platform rotatably placed on a vehicle of a crane, a display configured to display an image imaged by the imaging device, and a performance line arithmetic part configured to obtain a performance line regarding a suspended load maximum performance of a crane, wherein the performance line arithmetic part is configured to overlap the performance line with a position of the image corresponding to the obtained performance line to be displayed on the display.||01-10-2013|
|20120185159||FUEL CONSUMPTION DISPLAY APPARATUS FOR CRANE - A fuel consumption display apparatus for a crane includes: standby state determining means for determining whether or not a crane is in a standby state; fuel consumption detecting means for detecting fuel consumption of the crane; standby accumulated fuel consumption calculating means for calculating standby accumulated fuel consumption by accumulating the fuel consumption after the standby state determining means determines the crane to be in the standby state: the standby duration calculating means for calculating standby duration by measuring a time period after the standby state determining means determines the crane to be in the standby state; and a monitor for displaying the standby accumulated fuel consumption and the standby duration. An operator of the crane can therefore recognize how much fuel is wasted, thus facilitating an operation for reducing fuel consumption.||07-19-2012|
|20120138560||CRANE APPARATUS - A crane apparatus includes: a telescopic boom including a plurality of boom members, the telescopic boom performing telescopic motion by moving the plurality of boom members one by one using one telescopic cylinder; a condition input part configured to receive, as input, a condition for a crane operation including at least a weight of goods suspended by the telescopic boom, a height to which suspended goods are lifted, and a moving radius of the suspended goods; and a telescopic pattern selecting part configured to select a telescopic pattern that allows the crane operation under the condition inputted to the condition input part.||06-07-2012|
