Abstract: A work state monitoring device for a work vehicle is provided, such that an operator can perform the work without receiving a warning. The work state monitoring device acquires a current work state of a crane using work posture detectors. A calculator calculates at least a predetermined work state corresponding to a warning load factor based on the current work state acquired by the work posture detectors. A monitor informs an operator of the predetermined work state calculated by the calculator.

Abstract: A new rough terrain crane has an exhaust emission control device that has a DOC, a DRT, and a SCR. The DOC and the DRT are connected in series and disposed along a longitudinal direction of a vehicle. A rear end of the DOC is positioned at the front side relative to a rear end of an engine. The SCR is disposed in parallel to the DOC and both devices are disposed above a support member of a rear outrigger. The SCR is disposed on the upper side relative to the DOC at a position close to the engine.

Abstract: 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.

Abstract: 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.
