摘要： A lift crane includes a carbody; moveable ground engaging members; a rotating bed rotatably connected to the carbody, the rotating bed comprising a counterweight support frame; a boom pivotally mounted on the front portion of the rotating bed; a boom hoist system connected to the rotating bed and the boom that allows the angle of the boom relative to the plane of rotation of the rotating bed to be changed; a counterweight unit supported on the counterweight support frame in a moveable relationship with respect to the counterweight support frame; and a counterweight unit movement device connected between the rotating bed and the counterweight unit so as to be able to move the counterweight unit toward and away from the boom. The crane is configured such that during crane operation, the moment generated by the counterweight unit acts on the rotating bed predominantly through the counterweight support frame. Alternatively, the crane can include a mast connected to the rotating bed and a counterweight support beam moveably connected to the rotating bed and a tension member connected between the mast and the counterweight support beam; and a counterweight unit supported on the counterweight support beam in a moveable relationship with respect to the counterweight support beam. In some embodiments the same basic crane is configured to be set-up with two different counterweight options, i) the first option having a counterweight unit directly supported on the counterweight support frame and a counterweight unit movement device connected so as to move the counterweight unit with respect to the counterweight support frame, and ii) the second option having a counterweight support beam moveably connected to the remainder of the rotating bed and a counterweight unit supported on the counterweight support beam, with the counterweight unit movement device connected so as to move the counterweight support beam with respect to the counterweight support frame.

摘要： A mobile lift crane (10) includes a carbody (12); a rotating bed (20); a boom (22); a moveable counterweight unit; at least one linear actuation device (38) ; and at least one arm (36) pivotally connected at a first end to the rotating bed (20) and at a second end to the linear actuation device (38). The arm (36) and linear actuation device (38) are connected between the rotating bed (20) and the counterweight unit such that extension and retraction of the linear actuation device (38) changes the position of the counterweight unit compared to the rotating bed (20). In one method of operation, the counterweight is never supported by the ground during crane pick, move and set operations other than indirectly by the ground engaging members (14, 16) on the carbody (12). The linear actuation device can include at least one rack and pinion assembly (636) or hydraulic cylinder. In another embodiment, the crane comprises a counterweight movement structure including a rack and pinion assembly (636) having housing (720) and a rack (710), the rack (710) having a rectangular cross section with first and second sides (712, 714) opposite one another and third and fourth sides (712, 733) opposite one another, and having teeth on the first side and second sides (712, 714), and at least first and third pinion gears (716, 718) engaged with the teeth (722) on the first side of the rack and second and fourth pinion gears (732, 734) engaged with the teeth on the second side of the rack, and wherein each pinion gear is driven by a separate hydraulic motor, and wherein the motor driving the first pinion gear (731) is mounted on the housing (720) adjacent an opposite side of the rack (710) from the motor driving the third pinion gear (733), and wherein the motor driving the second pinion gear (732) is mounted on the housing (720) adjacent an opposite side of the rack from the motor (794) driving the fourth pinion gear (734). In another embodiment the crane includes a counterweight support structure attached to the counterweight unit. The counterweight support structure includes at least two ground engaging members that can provide support to the counterweight in the event of a sudden release of the load. The support structure comprises a telescoping structure connected to and between the ground engaging members such that the distance between the ground engaging members can be adjusted between a first and second position.

摘要： Crane, in particular large mobile crane, having a revolving superstructure (3), having at least one jib (1) and at least one counter-jib (2) and having a counterweight (5) arranged separately from the revolving superstructure (3) and connected to the tip of the counter-jib (2). A modular counterweight system, which has the maximum superlift counterweight envisaged for the crane without a correspondingly large carriage being required, further ensures the mobility of the crane. The revolving superstructure (3) has at least one degree of freedom of movement in relation to the ground or its base, and the separately arranged counterweight is divided up into a displaceable counterweight (5, 9, 10) and a non-displaceable counterweight (13, 16), these being connected to one another and to the counter-jib (2) such that the non-displaceable counterweight (13, 16) can be activated before the displaceable counterweight (5, 9, 10).

摘要： A telescoping camera crane (30) has mechanical drive (102) and camera platform leveling systems (50,104,342,260,450), allowing for water resistant or submerged operation. Telescoping sections (54,56) of the crane arm (35) are driven by a hydraulic system (100), for smooth and near silent extension and retraction movement. Camera platform leveling and stabilizing systems (50,104,342,360,450) keep the camera level. A shock and vibration isolator (540) for the camera has a vertical axis system, including a base (548), an arm (558) pivotably attached to the base, and at least one spring (566) connected to the base and to the arm. One or more dampeners (590) are connected to the base and to the arm. A horizontal axis system (610) is supported by the vertical axis system. A leveling linkage (602) connects the vertical and horizontal axis systems. The leveling linkage has adjustment features that allow for compensation of camera lens angulation caused by movement of the camera (536) supported on a vehicle (32) rolling over rough or uneven ground.

摘要： Der Rohrverleger 1 weist ein Unterfahrzeug 2 mit einer Fahrerkabine sowie einen auf dem Unterfahrzeug 2 abgestützten Ausleger 10 auf, der um eine waagerechte Neigungsachse 11 heb- und senkbar ist. Außerdem ist der Ausleger 10 mittels eines Drehkranzes um eine senkrechte Schwenkachse verschwenkbar. Am äußeren Ende des Auslegers 10 ist ein Seilrollenkopf 31 mit einer Umlenkrolle 26 und einer Seilrolle 28 vorgesehen, der sich insgesamt um eine Einstellachse 32 gegenüber dem Ausleger 10 verschwenken läßt. Diese Einstellachse 28 verläuft in Längsrichtung des Auslegers 10. Mittels einer mechanisch oder hydraulisch betätigbaren Blockiereinrichtung kann die Schwenkstellung des Seilrollenkopfes 31 gegenüber dem Ausleger 10 auch blockiert werden. Infolge der Verschwenkbarkeit sowohl des Auslegers 10 wie des Seilrollenkopfes 31 kann die Rohrverlegearbeit einfacher und schneller durchgeführt werden.

摘要： An aerial work platform apparatus includes a shiftable counterweight (36) which shifts in response to movement of the boom (32) in order to maintain optimum balance of the apparatus during movement of the boom and platform (22). The counterweight shifts towards and away from the front of the apparatus, and also in a vertical direction. The counterweight is supported by rollers (40) and moves along an inclined track (42). The counterweight is pushed by a link (46) mounted on the second (32') end of the boom, or in an alternative embodiment by a hydraulic cylinder (58), which is linked to the boom lift cylinder (54) in a master-slave arrangement.
