Definitions

the invention relates to a method for overload protection of a mobile crane.
Statutory regulations require overload protection for all mobile cranes.
An overload protection for mobile cranes is required, their load capacity greater than 1,000 kilograms or whose load torque is greater than 40,000 Nm.
mobile Cranes are, for example, mobile cranes, mobile harbor cranes, crawler cranes, Etc.
the switch-off curves required for overload protection are already known for all possible set-up conditions of the respective mobile crane and in the memory of the overload protection.
the switch-off curves are there represented by a number of points that were calculated. Between these Points are interpolated during operation.
the invention is based on the object of a method for overload protection of a mobile crane, in particular a crawler crane, with which the current switch-off values even with a large number of possible setup states can be determined quickly and precisely.
this object is achieved by a method for overload protection a mobile crane according to the combination of features of claim 1 solved.
control computer of the crane no more dumping load curves stored in the assigned memory, but geometry files with the physical properties of the components of the crane.
the corresponding geometry data corresponding to the set-up state are then compiled in a physical simulation model in the control computer. Now the real measurement data from the force and position sensors on the crane side determined and from this the geometric on the control computer Data, focus data and forces and then the switch-off values determined. When the crane is in operation, it will then, if necessary, reach a switch-off value switched off.
the components are related to the memory Geometry data for each component type of the crane components in assigned Geometry files filed. So it is no longer a complete boom recorded, but the data of the boom spacers and the other component types geometry files assigned to them are stored. It is One geometry file per component type is required. In a corresponding crane configuration file the instructions are stored in parallel, according to the crane components can be combined with each other. Here are the different ones Possible combinations of the individual component types to complete booms or add-on parts.
the crane configuration file also a pre-selection option for calculating the switch-off values entered.
These pre-selection options are, for example to a calculation specification for permissible loads according to the national legislation. So the permissible loads differ in the USA, for example, from those in Europe (according to the EN 13000 standard). Because of the inventive method and the storage of the corresponding The calculation rule can modularly result by accessing the respective data stored in the memory are put together. According to the state of the Technology you were still forced to do for each different calculation rule, i.e. for example, every different legal regulation, a new one to calculate complete set of payload curves and in the corresponding to put down mobile crane.
the values calculated in the control computer are advantageously displayed on a Played display device.
this Display device not only the permissible load and the corresponding Limit curve, but at the same time as a "waste product" of the simulation model the actual load, the outreach, the crane height etc. are displayed.
Another advantageous embodiment of the invention is that the setup information the operator in the selection device on a display device are reproduced. So here he can see the Assemble the crane with the equipment as it is assembled in reality is.
the instructions are on the one hand about how the crane components are combined can.
the crane configuration file 14 contains in the embodiment shown here also pre-selection options, which the calculation of the switch-off values influence.
the calculation rule for permissible loads can be used here as an alternative for the USA or for Europe. Upon delivery of the corresponding Cranes to the USA then only have to apply the appropriate calculation rule can be retrieved in the later calculation.
a selection device 16 the desired setup conditions are then from Device operator compiled.
a screen not shown here, serves this purpose, on which the crane operator with an appropriate manipulation device, which is also not shown, assemble the crane as it is the reality corresponds.
