    Abstract: A self-maintaining crane system including a bridge, a trolley, a hoist, and sensors for use within a hostile environment, such as a wastewater treatment facility, is presented. The bridge is movable along a pair of runway rails. The trolley is movable between the runway rails. The hoist with extendable-retractable cable is movable with the trolley. Bridge sensors determine whether the bridge has engaged home and end positions. Trolley sensors determine whether the trolley has engaged home and end positions. The bridge and the trolley are movable between home and end positions. Hoist sensors determine whether the cable has engaged a hoist home position and a hoist end position. The cable is extendable away from the home position and retractable toward the end position. Sensors facilitate automated movement of bridge, trolley, and cable so as to minimize functional impairment of the crane system by the hostile environment.

    Abstract: A crane vehicle achieves safe movement by reliably detecting an obstacle in a region which is a blind spot from the opposite side of the driver seat across a boom. The crane vehicle includes an obstacle sensor which is a transmission/reception antenna that transmits a detection wave and receives the detection wave reflected from the obstacle. A signal corresponding to the reflected wave received by the obstacle sensor is amplified and input to a controller, which calculates the position and the size of the obstacle on the basis of the signal. The controller generates an obstacle display image and displays the image on a display, the obstacle display image including a vehicle object that represents a crane vehicle and an obstacle object which is an object corresponding to the calculated size of the obstacle and which is disposed at a position corresponding to the calculated position of the obstacle.

    Abstract: A heavy equipment hazard warning apparatus for a piece of heavy equipment at a site and a system and method for use of the same are disclosed. In one embodiment of the heavy equipment hazard warning apparatus, the location of the heavy equipment is monitored by the heavy equipment warning apparatus and analyzed with reference to a hazard safety site plan of the site that identifies a hazard such as existing utilities, for example. An alert notification is initialized in response to the heavy equipment encroaching on a hazard geofence around the hazard. A shutdown notification is initialized in response to the heavy equipment being proximate to the hazard.

    Abstract: The invention relates to a method for monitoring a working machine, in particular a crane, which is equipped with two or more individual elements for use when in operation, wherein a working machine monitoring means unambiguously identifies one or more elements equipping the machine and determines their times of operation, and the determined time of operation of at least one of the element is transmitted together with identification information to storage means for establishing an operation log of the element.
