A system includes a hoist drive mechanism that elevates and lowers a load hook from a boom and a detector that provides obstacle location and identification information. A processor receives the obstacle location and identification information from the detector and provides obstacle avoidance data in response thereto.

A control stand is disclosed for controlling a crane, an excavator, a crawler, or a similar construction machine having a seat, control elements actuable from the seat for inputting control commands, a display apparatus for displaying information, and a control unit for generating adjustment signals in dependence on input control commands and/or for providing information to the display apparatus. A crane is disclosed having such a control stand that can be configured in the form of a crane operator's cabin. The control elements and/or the display apparatus of the control stand and various further auxiliary units can be individually configurable. Personal pre-settings can be saved and can be reinvoked when the control stand or the crane is to be controlled by a certain machine operator.

A crane or mobile crane includes a crane base, a crane jib to be slewed relative to the base about a slewing axis vertically oriented in normal operating state. A counterweight carrier coupled to the crane jib slews therewith and carries counterweight modules in normal operating state. An anti-collision sensor system monitors the presence of an object within a slewing range ahead being passed through by the counterweight carrier and/or counterweight modules in the future during normal operation as the crane jib slews. A control unit linked to the anti-collision sensor system for signal transmission is configured to determine, based on sensor signals transmitted by the anti-collision sensor system, whether an object is present in the slewing range ahead, to determine whether the object can lead to a collision with the counterweight carrier or one counterweight module, and to take a countermeasure upon a collision.

The invention relates to a wheel system having a running wheel and a support body which at least partially surrounds the running wheel and in which the running wheel is mounted and from which the running wheel projects in order to come into contact with a rail. In order to allow predictive maintenance of the wheel system with a low inspection effort, it is proposed that a mechanical device for detecting and/or determining wear on the running wheel is mounted on the support body.

A hoist lifting system having planning and monitoring of components. The system monitors one or more components and may have a processing structure and memory storing instructions to configure the processing structure to: receive hoist machine data; determine a rotation speed of a bearing, a travel speed of a rope, a load on the bearing, a friction in the at least one bearing based on the hoist machine data; and store the rotation speed, the travel speed, the load, and the friction in a maintenance database in memory. The hoist lifting system may have the processing structure determine a wear of one or more components.

A camera and a laser radar are attached to the hoist of an overhead crane. Image data and three-dimensional point clouds are acquired during operation and accumulated as operation result data. An information processing apparatus displays the crane's movement trajectory on the terminal and predicts maintenance timing based on operation result data, evaluates a degree of danger and detects an occurrence of accident based on a positional relationship between the crane and an operator, performs optimization of a movement path, a transport sequence of multiple suspended loads, a layout in the facility, and the like, and performs post-operation diagnosis for the degree of danger and operation efficiency of the crane. In addition, the crane is used to scan the inside of the facility to detect abnormalities such as fires and suspicious persons after the work hours of the facility. These treatments can improve the usefulness of the crane.

A crane anti-collision system, containing: a scanning apparatus installed in the crane, containing a laser scanner arranged to measure the optical distance to targets from the crane in the first direction of travel; and a detection apparatus arranged to automatically detect targets by the scanning apparatus. The detection apparatus is arranged for: defining by the scanning apparatus a three-dimensional reference zone of the goods handling area that is composed of the surface and vertical tolerance of the goods handling area; and detecting a target in the goods handling area on the basis that the height defined by the scanning apparatus differs from that of said reference zone. Further described is a control system, an anti-collision method, an anti-collision program, and a manufacturing method for an anti-collision system.

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.
