摘要:
A guidance system for manually guided vehicles such as reach stackers or straddle carriers is disclosed. In accordance with the disclosure, the position of the vehicles is permanently automatically detected and supplied to a guiding system for carrying out. Starting from transport job lists made available externally, the travel jobs are assigned to the individual vehicles in an optimized form. Suitable travel routes for the travel jobs are determined and the travel jobs, including the travel routes, are automatically transferred to the vehicle operators. Their carrying out is monitored.

The invention refers to a crane or excavator for the transaction of a load, which is carried by a load cable with a turning mechanism for the rotation of the crane or excavator, a seesaw mechanism for the erection or incline of an extension arm and a hoisting gear for the lifting or lowering of the load which is carried by a cable with an actuation system. The crane or excavator has, in accordance with the invention, a track control system, whose output values are entered directly or indirectly as input values into the control system for position or speed of the crane or excavator, whereas the set points for the control system in the track control are generated in such a way that a load movement results from it with minimized oscillation amplitudes.

The present invention comprises a method for the control of a drive of a crane, in particular of a slewing gear and/or of a luffing mechanism, wherein a desired movement of the boom tip serves as an input value on the basis of which a control parameter for the control of the drive is calculated, characterized in that the oscillation dynamics of the system comprising the drive and the crane structure are taken into account in the calculation of the control parameter to reduce natural oscillations. The present invention furthermore comprises a method for the control of a hoisting gear of a crane, wherein a desired hoisting movement of the load serves as an input value on the basis of which a control parameter for the control of the drive is calculated.

The present invention shows a crane control of a crane which includes at least one cable for lifting a load, wherein at least one sensor unit is provided for determining a cable angle relative to the direction of gravitational force. Furthermore, there is shown a crane control for driving the positioners of a crane which includes at least one first and one second strand of cables for lifting the load, with a load oscillation damping for damping spherical pendular oscillations of the load, wherein first and second sensor units are provided, which are associated to the first and second strands of cables, in order to determine the respective cable angles and/or cable angular velocities, and the load oscillation damping includes a control in which the cable angles and/or cable angular velocities determined by the first and second sensor units are considered. Furthermore, a corresponding crane and a method are shown.
