In a method for preventing a collision of a load of a crane with an obstacle, a height profile of the obstacle is captured along a trajectory of movement of the load by at least two sensors for distance measurement. Signals of the sensors are transmitted via at least two communication channels to a controller having at least two operating systems. At least one of the operating systems has a safety program in a secure area. The obstacle is identified along the trajectory via the height profile. The controller includes a secure communications interface for transmitting signals from the controller to a crane control.

A method for detecting collision risks when moving a load includes the following steps: attaching a plurality of proximity sensors around the lateral surface of the load; lifting and moving the load using the lifting and moving equipment; transmitting and displaying the signals generated by the proximity sensors on at least one display unit.

In a method for a collision-free movement of a crane in a crane lane, a sensor captures a first training data set of raw data during a movement of the crane outside a crane operation in the crane lane. The first training data set is evaluated while teaching a first neural network based on the captured raw data and first training data are determined from the evaluated first training data set. The sensor captures current sensor data during a movement of the crane during the crane operation in the crane lane. The current sensor data is compared with the first training data, and an anomaly is detected between the current sensor data and the first training data.

The present disclosure relates to engineering machinery and a dynamic anti-collision method, device, and system for operation space thereof. The dynamic anti-collision method for operation space includes: receiving obstacle information of an obstacle around a boom of engineering machinery and boom motion information of the engineering machinery; determining obstacle coordinates according to the obstacle information and the boom motion information; deciding whether the obstacle coordinates are located in a predetermined early warning area or not; and indicating an execution device to send out collision warning information in case where the obstacle coordinates are located in the predetermined early warning area.

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.

The present invention relates to a method of moving a load using a crane comprising the steps: defining an origin coordinate system in the crane; defining at least one obstacle coordinate system that is fixedly linked to a deployment location of the load movement; establishing a relationship of the at least one obstacle coordinate system with the origin coordinate system; predefining a travel path of the hook block, preferably with the suspended load, with the aid of the at least one obstacle coordinate system; and converting the travel path from the obstacle coordinate system into actuator controls of the crane for a corresponding movement of the hook block, preferably with the suspended load.

An obstacle detection device detects an obstacle existing in one or more monitoring areas that are set to correspond to a movable part. A state determination unit determines whether a state of the actuator is a standby state or a suspended state under circumstances where the actuator is at a stop. On determination that the state of the actuator is the standby state, a display control unit executes automatic image output that is processing for causing a display device to display a monitoring image corresponding to a monitoring area in which the obstacle is detected out of the one or more monitoring areas. On determination that the state of the actuator is the suspended state, the display control unit stops the execution of the automatic image output.
