Definitions
- the invention relates to a crane with an electronic control that can be operated by an operator via manual input units for actuating drives for at least one hoist and for crane movements, the sensitivity (resolution) of the manual input units being adjustable.
- a crane regularly has not only a drive for at least one hoist for lifting a load, but also one or more drives for executing crane movements.
- Such crane movements can be seen, for example, in the adjustment of the inclination of the boom of the crane and in particular in pivoting movements of the boom about a vertical axis of rotation.
- the respective drives are actuated via manual input units, which are usually designed in the form of control levers. By deflecting such control levers to different extents, the speed of the respective drive coupled therewith can be set arbitrarily to values of different sizes.
- Modern cranes are regularly provided with an electronic control system, which receives its control commands via the manual input units already mentioned and converts them into corresponding signals for controlling the drives.
- an electronic control system which receives its control commands via the manual input units already mentioned and converts them into corresponding signals for controlling the drives.
- it is customary to compensate for the effects of mechanical and electronic components, which would lead to different system behavior in the individual cranes, by adjusting them accordingly, so that practically the same for every device of a crane type System behavior can be guaranteed.
- This means that the adjustment ensures that when a manual input unit is actuated in a certain way, the respective drive always reacts in the same way regardless of which device of the respective type is currently being used. This prevents the crane operator from having to adjust to the behavior of a new crane in a learning phase when changing between individual cranes.
- the object of the present invention is to develop a crane of the generic type in such a way that, in accordance with the requirements of the respective lifting task that is to be solved with the crane, optimal operation by crane operators can be ensured in spite of their different forms of behavior.
- This task is solved in the case of a generic crane in that the electronic control has at least two settings which can be selected by the operator and which each specify different sensitivities for the manual input units for the crane operation.
- the present invention thus makes it possible to adjust the sensitivity of manual input units, i.e. to adjust their resolution or spread, in order to consciously cause a behavior of the system of the crane drives that is clearly different from normal behavior.
- this is a reproducibly different system behavior that is always present when the electronic control has been selected accordingly by the crane operator.
- a touch screen connected to the electronic control has proven to be particularly expedient here, because this not only enables easy-to-learn programming, for example via displayed symbols, but also provides a display of the set values.
- a factory-set normal setting is expediently stored in the electronic control in such a way that a change can only be made by trained personnel. This ensures that, in the case of confused programming, in which the manual input units operate in an objectively nonsensical manner
- the spread of the manual input units is expediently increased significantly compared to the normal setting, that is to say the
- Sensitivity reduced so that sensitive adjustment is guaranteed even by less sensitive operators.
- the spread of the manual input units for the assembly operation can be so pronounced that the maximum speed of the respectively assigned drive is no longer normal can be reached, but can only be activated by switching to another operating mode.
- the invention provides for the sensitivity of the manual input units not to be set linearly, but to be set up in the form of a characteristic curve in which there is a comparatively high resolution of the actuating movements in an initial fine control range (large spread) and a progressively changing course in the other range the characteristic curve is provided so that the maximum speed of the respective drive can be reached quickly (smaller spread).
- the electronic control has a control program which excludes the storage of settings in which the achievable values of speed and dynamics would each lie outside the values permitted for the crane.
- the inventive design of the electronic control of a crane enables the behavior of the manual input units of the crane to the individual needs adjust the j ehat crane operator and the respective lifting task in a particularly favorable manner.
- the crane operator can use a corresponding programming of his control to increase the resolution on the control levers to a wide spread and set long ramp times. This can ensure that even when the control levers used as manual input units move clearly, only slow speeds are produced on the drives.
- control can be set for fast operation, which is particularly advantageous on construction sites when lifting smaller loads with little reeving of the hoisting rope for fast movements with high dynamics and short ramp times.
- the structural effort required to implement the present invention is low, since essentially only the corresponding memory space in the control and a software program have to be made available for this.
