| 20080246658 | Mobile crane - The present invention relates to a mobile crane having means for wireless reception or for the determination of data identifying the location of the crane as well as having transmission means which are in communication with these means or can be connected to them, wherein the transmission means are configured such that they transmit the data identifying the location of the crane from the crane to a receiver in a wireless manner. | 10-09-2008 |
| 20090276126 | Mobile crane and method for operating a mobile crane - This invention relates to a mobile crane with at least one memory unit in which limit curves or limit values are stored for various crane parameters, which should not be exceeded, or only by issuing an alarm signal, to ensure safety during operation of the crane, and with means for ensuring crane safety, which are configured such that they monitor the individual limit values of the various parameters for exceedance, and with means for checking the current position of the extendable and retractable props which serve to support the mobile crane. In accordance with the invention, means are provided, which in dependence on the actual position of the supporting cylinders reached determine the tilting edge of the mobile crane as limit value. Furthermore, means are provided, which in dependence on the individual parameters of the mobile crane and the suspended load determine whether the operating condition of the mobile crane lies within this limit value. | 11-05-2009 |
| 20100050864 | Piston-Cylinder Unit - The present invention relates to a piston-cylinder unit with a piston with adjoining piston rod, which is movably mounted in a cylinder, wherein the piston and the piston rod have a cavity into which at least one rod protrudes, by means of which an electrically conductive connection can be made directly or indirectly. | 03-04-2010 |
| 20110089131 | Hoisting Limit Switch and Lifting Device - The present disclosure relates to a hoisting limit switch for limiting the maximum allowed hoisting height of a hoisting cable, wherein the hoisting limit switch includes a read-write device for reading and writing data, and a means from which the operating condition of the hoisting limit switch can be read out by the read-write device. | 04-21-2011 |
| 20110153038 | CONTROL SYSTEM FOR CONSTRUCTION MACHINES AND METHOD FOR OPERATING THE CONTROL SYSTEM - A control system for a construction machine includes at least one sensor and at least one controller, wherein a serial connection exists between the sensor and the controller, and wherein at least one sensor and/or controller are of the two-channel or multi-channel type. Furthermore, this invention relates to a method for operating such control system for a construction machine. | 06-23-2011 |
| 20110153277 | SENSOR - A sensor for measuring any desired variable, with the sensor having a sensor housing with a specimen feed and with at least two measured value pick-ups and at least two processing units being arranged redundantly respectively pairwise with respect to one another and/or diversely in the sensor housing. | 06-23-2011 |
