Provided is a crane that can detect obstacles within a sufficient range while traveling and while doing work. A crane that is provided with an obstacle sensor that, during travel, detects the approach of obstacles toward a front side part of a travel body and, during work, detects the approach of obstacles toward a rear side part of a turning body. According to a first embodiment, the obstacle sensor has a detection range that is directed from front to rear. According to a second embodiment, the obstacle sensor has a detection range that is directed from rear to front.

This disclosure provides a system and method for limiting a swing angle of a jib crane, the jib crane having a jib rotatably mounted to a mast. The device can have a collar having a collar height and a collar width, the collar being configured to be fit to the mast at a stop height. The device can also have one or more stopping tabs enagagable with the collar and configured to be positioned on the collar at one or more points about a circumference of the mast. The stop height can place the one or more stopping tabs in a position coincident with the jib to interfere with the swing angle of the jib. The method can use the device to limit the angle through which the jibe crane can swing unimpeded.

A rough terrain crane is equipped with dashboard cameras and digital cameras for capturing bird's-eye view image thereof. The equipment performs, when a load factor reaching 90%, a process of recording start for starting image data recording with the digital camera and a process of storing measurement value for recording a load factor concurrently with the process of recording start. The image data is recorded with the digital camera associated with the above activation condition, among the digital cameras installed in the rough terrain crane.

A crane includes a boom and a hook suspended from the boom by a wire rope and transports a load in a state in which the load W is suspended from the hook, and further includes a sensor that detects the position of an obstacle, and a control device that generates a transport path CR by arranging a plurality of node points in an area containing a lifting-up point and a lifting-down point of the load and connecting the node points. The control device generates a new transport path after increasing a number of node points arranged around the obstacle when the sensor detects movement of the obstacle.

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.
