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 within the hostile environment. The trolley is movable between the runway rails. The hoist with extendable-retractable cable is movable with the trolley. Bridge sensors separately determine whether the bridge has engaged a bridge home position and a bridge end position. The bridge is movable away from the bridge home position and back toward the bridge end position. Trolley sensors separately determine whether the trolley has engaged a trolley home position and a trolley end position. The trolley is movable away from the trolley home position and back toward the trolley end position. Hoist sensors separately determine whether the cable has engaged a hoist home position and a hoist end position. The cable is extendable away from the hoist home position and retractable toward the hoist 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.

A crane risk logic apparatus and system and method for use of the same are disclosed. In one embodiment of the crane risk logic apparatus, the crane risk logic apparatus is integral with a crane, such as a crawler crane or a tower crane, and located in communication with a load moment indicator. The crane risk logic apparatus receives crane data from the load moment indicator and determines lift cycle data therefrom. The crane risk logic apparatus determines an area of interest based on locationing data received from a global positioning system (GPS) unit incorporated therewith and receives weather data for this area of interest. The crane risk logic apparatus causes an alert notification at the crane to occur in response to presence of weather issues.

A crane block mountable safety beacon device for increasing awareness of a crane block includes a housing that is mountable to a crane block. A set of bulbs that is coupled to the housing selectively emits light to indicate a position of the crane block to an operator of a crane utilizing the crane block and to persons proximate to the crane block.

A crane barrier access warning system suspended by four or more pinned adjustable telescoping supports, which extend outward from a cranes lower car body between the tracks. One of the telescoping members end inserts into a mounting frame, which comprises of other pinned adjustable telescoping components, so that it can be fitted to the frame or track beams. This entire safety barrier system is erected without tools. The components that form the actual safety barrier surrounds the whole crane and are suspended from it so that the safely barrier moves with the crane. Suspension components are adjustable through their pinned telescoping members so that the invention can fit different sized cranes. All the parts can be separated and fully retracted for shipping or storage.

The present disclosure relates to a method for real time monitoring of the current status of a construction site having one or more work machines, wherein a monitoring means installed at least one work machine monitors the environment of the work machine in real time and generates corresponding monitoring data, with the generated monitoring data being transmitted by the monitoring means to at least one processing unit for a real time evaluation of the current construction site status.

The invention relates to a method for determining the replacement state of wear of a rope made of a textile fibre material, wherein, in the course of using the rope, the elongation of the rope is monitored over its entire length and the rope is discarded if the elongation of the rope over the entire length exceeds a predetermined maximum value (%). The method according to the invention is characterized in that also the local elongation of a discrete rope section is monitored and the rope is discarded if the local elongation of the rope section exceeds a predetermined maximum value (%), with the maximum value of the local elongation of the rope section being greater than the maximum value of the elongation of the rope over the entire length.
