A method for moving a load with a crane in a collision-free manner in a space having at least one obstacle includes providing a position of the obstacle, providing at least one safe state variable of the load, determining from the safe state variable a safety zone surrounding the load, and dynamically monitoring the safety zone in relation to the position of the obstacle.

Method for moving a load with a crane in a collision-free manner

A control unit of the crane controls drives that move an upper load suspension point and, together therewith, a load suspended via a cable system. As the upper load suspension point is moved, an inner safety zone around the load is repeatedly dynamically determined according to state variables of the crane. The state variables include at least a position and a speed of movement of the upper load suspension point, and an effective pendulum length of the load. The control unit checks, based on further known information whether an object different from the load has entered the inner safety zone, in which case the movement of the upper load suspension point is stopped or a message to stop the movement is outputted to an operator of the crane. Otherwise, the movement is maintained or no message to stop the movement is outputted to the operator.

Collision-free guidance of a load suspended from a cable

A control method for a handling system includes when a trolley is loaded at a target location by a target loading, matching by a crane controller the target location of the trolley on a crossmember with a target location of a load handling point on the substrate, such that a target load is lowered onto the target location of the load handling point, when the target load is lowered at the target location of the trolley, positioning the trolley at the target location by the crane controller, subsequently lowering the target load onto the load handling point by the crane controller and positioning the load handling point at the target location before the target load is lowered onto the load handling point, when the load handling point is movable on the substrate and the load handling point is controlled by the crane controller.

Automated crane controller taking into account load- and position-dependent measurement errors

Systems, methods and computer program code for the measurement and control of sway in load transportation systems are provided which include using Micro-Electro-Mechanical Systems (MEMS) devices to measure and control the sway of suspended loads such as loads suspended from cranes.
