| 20090026426 | Truck crane - The present invention relates to a truck crane with a winch, in particular a hoisting winch, which is mounted on the uppercarriage, wherein the truck crane includes means for raising and/or lowering the winch. | 01-29-2009 |
| 20090127219 | Method for erecting a crane boom - This invention relates to a method for erecting a main boom of a truck crane, which at least consists of a telescopic boom, with a fly jib which is braced via bracing trestles and bracing rods, and with a spatial boom bracing. In accordance with the invention, the main boom is braced by means of the spatial bracing before being completely connected with the fly jib. | 05-21-2009 |
| 20090134108 | Method of raising a crane boom - The invention relates to a method of raising a telescopic boom of a mobile crane having a luffing fly jib and having a spatial boom guying. To be able to raise particularly long luffing fly jib systems together with the telescopic boom here, in accordance with the invention the telescopic boom is first telescoped outwardly to its desired length. In this position, all the telescopic sections are bolted to one another and the spatial guying is tensioned before the raising of the luffing fly jib pivotally connected to the telescopic boom. | 05-28-2009 |
| 20100155355 | Rotary Joint - The present disclosure relates to a rotary joint for rotatable connection of the uppercarriage with the undercarriage of a crane, wherein they can each be connected with the uppercarriage on the one hand and the undercarriage on the other hand via a quick-release coupling. | 06-24-2010 |
| 20100158654 | Unknown - The present invention relates to a manipulator, preferably for the assembly of rotor blades of a wind power installation, having a receiving unit for the receiving of a rotor blade and having a connection unit via which the manipulator is connected or connectable to the boom of a crane in a torque-rigid manner so that the position and/or alignment of a rotor blade received in the receiving unit relative to the boom can be fixed by the manipulator. | 06-24-2010 |
| 20110049075 | Crane - The present disclosure relates to a crane with a travelling undercarriage, an uppercarriage rotatably mounted on the same with a luffing boom and derrick boom arranged on the same, and a ballast carriage connectable with the uppercarriage via a coupling element, wherein the ballast carriage is a standardized heavy-duty transport device with separate drive and separate drive controller, and wherein this drive controller can be influenced as a result of the movement of the crane. | 03-03-2011 |
| 20110084043 | Crane - The within invention relates to a crane with a boom slewable in a vertical pivoting plane and a bracing boom arrangement, particularly a derrick boom arrangement in which a luffing cable is arranged between the boom and the bracing boom arrangement, in which the luffing cable has at least two guying cables that run from two guying points arranged on the opposite side of the pivoting plane, which cables belong to the bracing cable arrangement, to the boom, in which the two guying cables are each movable by means of a winch and in which a mechanical coupling is provided between the two winches by means of which the movement of the two winches can be force coupled. | 04-14-2011 |
| 20110174555 | CRAWLER TRAVEL GEAR AND CRAWLER-MOUNTED CRANE - A crawler travel gear that can be applied to a crawler-mounted crane. The crawler travel gear includes a crawler carrier, rollers arranged at the crawler carrier and a crawler chain, with a respective adjustment mechanism provided in the front region and rear region of the crawler carrier for selectively adjusting the contact surface of the crawler carrier relative to an underlying surface. | 07-21-2011 |
