20150129330 | WORKING VEHICLE - There is provided a working vehicle that can continuously drive a working machine by electric power to improve the silence. The hydraulic pump is driven by the power of the motor generator that is driven by the electric power of an external power supply supplied via the power cable. By this means, when a crane operation is performed by the crane apparatus in a workplace with an external power supply, it is possible to continuously drive the hydraulic pump by the power of the motor generator, and therefore to continuously perform the crane operation of the crane apparatus, improving the silence. | 05-14-2015 |
20140353272 | JIB ATTACHMENT/DETACHMENT MECHANISM - A jib attachment/detachment mechanism to mount a jib on a boom head includes a guide mechanism including a guide roller and a guide support configured to guide engaging portions of a jib support to positions of engagement with shaft pins of a boom head when the jib support is pulled up with a wire by using a winch and to prevent change of a state of the wire pulled up by the winch when the jib support is rotated around the shaft pins by contracting a cylinder. | 12-04-2014 |
20140346132 | TELESCOPIC BOOM - A telescopic boom provided in a crane includes a boom body and a telescopic cylinder for extending/contracting the boom body. A roller is provided in a tip end portion of the telescopic cylinder to be rotatable in a longitudinal direction. A peripheral surface of the roller is formed to be curved (crowning) in a convex shape outside as viewed in the longitudinal direction and make contact with a lower plate of the boom body in a state where both corner parts are away from the lower plate. | 11-27-2014 |
20140297136 | DEVICE FOR SELECTING BOOM EXTENSION PATTERN - When an extension pattern selection device is activated, a normal mode is displayed on a screen of a monitor. An operator presses a manual mode switch key of an operation unit to switch the display mode of the screen from the normal mode to an extension pattern manual rearrangement mode. In the extension pattern manual rearrangement mode, the operator rearranges extension patterns so that frequently selected extension patterns P may be displayed at upper positions. Thus, the frequently selected extension patterns P are more preferentially displayed than the other extension patterns P. | 10-02-2014 |
20140258908 | MACHINE DISPLAY SYSTEM - A machine display system is disclosed. The machine display system comprises: an information-obtaining device which obtains information regarding a condition of an operating machine; and a controller which displays a screen on a display by using the information regarding the condition of the operating machine obtained by the information-obtaining device, wherein the controller adds a particular mark to at least one of the screen and an image on the screen, and the display shows the screen and/or image with the particular mark. | 09-11-2014 |
20140083968 | TELESCOPIC BOOM - A telescopic boom includes a first frame having a curved portion whose section is substantially U-shaped, and a second frame connected to the first frame so that a closed section is formed. In the telescopic boom, the U-shaped curved portion of the first frame includes a plurality of protrusion portions formed at intervals in a circumferential direction of the telescopic boom, each protrusion portion extending in a longitudinal direction of the telescopic boom and being formed to have an arc-shaped section and protrude to the outside of the first frame. | 03-27-2014 |
20140035923 | WORKING RANGE DIAGRAM AND WORKING RANGE DIAGRAM-DISPLAY APPARATUS - Provided is a working range diagram and a working range diagram-display apparatus with which a working range can be easily grasped. The working range diagram shows a working range in which a boom of a working machine having the boom can safely move with a three-dimensional spatial coordinate system. In the working range diagram, a part of or all of forward performance, backward performance, right sideward performance and left sideward performance in the working range is shown in different display formats. Since the working range is shown three-dimensionally and the frontward performance, the backward performance, the right sideward performance and the left sideward performance can be distinguished from each other, the working range can be easily grasped. Consequently, a mistake in a work plan is hardly made due to a subjective impression or a misunderstanding, thereby preventing rework or the like. | 02-06-2014 |
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 |
