摘要:
Die vorliegende Erfindung betrifft einen Kran, insbesondere Turmdrehkran, mit einem um eine aufrechte Drehwerksachse [5] drehbaren Ausleger [3] sowie einer Außerbetriebs-Bremse [10], die Drehbewegungen des Auslegers [3] im Außerbetriebs-Zustand zulässt und abbremst. Erfindungsgemäß ist die Außerbetriebs-Bremse [10] drehgeschwindigkeitsabhängig arbeitend ausgebildet derart, dass das aufgebrachte Bremsmoment bei größerer Krandrehgeschwindigkeit größer ist als bei kleinerer Krandrehgeschwindigkeit.

The invention relates to a vehicle (10) comprising at least one of (i) an undercarriage (20) and an upper carriage (30) arranged rotatably about a vertical axis (90) with respect to the undercarriage (20) and (ii) a leverage means (40) arranged pivotably about a horizontal axis (80) with respect to the upper carriage (30), wherein a sensor system (100) is provided for monitoring at least one stability criterion with respect of a tilt movement of the vehicle (10), and wherein a control unit (150) is coupled to the sensor system (100) for automatically initiating an action and/or performing an action for stabilizing the vehicle (10) depending on the at least one stability criterion. The risk of an unexpected tilting of the vehicle (10) can be reduced
摘要:
Cet indicateur (7) évite les erreurs systématiques dues à des arrondis. Il comprend un capteur angulaire (8) entraîné en rotation par l'intermédiaire d'un pignon (10) qui engrène avec une couronne dentée (4) appartenant au mécanisme de rotation de la grue. Le nombre de dents (d) du pignon (10) est égal à une puissance de deux, par exemple à seize, de telle sorte que, quel que soit le nombre de dents (D) de la couronne (4), le rapport de réduction (R = D/d) soit un nombre décimal possédant un nombre fini de décimales. La valeur exacte de ce rapport (R) peut ainsi être introduite dans un calculateur (12), pour déterminer le nombre de tours effectué par la flèche à partir du nombre de tours mesuré par le capteur (8). L'invention est applicable aux grues à tour et aux grues à flèche relevable.
摘要:
A swing lock mechanism (98) for machines having an upper works (12) rotatably mounted on a lower works (16) by a swing bearing (18) is connected to the drive shaft (90) of a swing bearing drive assembly (80) and comprises a swing lock plate (100), an annular pin support (106), and a plurality of locking pins (104). The swing lock plate (100) is affixed to the drive shaft (90) and has at least one hole (102) disposed about the axis of the drive shaft (90). The annular pin support (106) is fixed against rotation relative to the drive shaft (90) is disposed about the axis of the drive shaft (90). The locking pins (104) are supported by the annular pin support (106) and are also disposed about the axis of the drive shaft (90). The locking pins (104) are arranged in such a manner so as at least one pin may engage a hole in the swing lock plate (100) irrespective of the angular orientation of the swing lock plate (100) relative to the annular pin support (106).
摘要:
A locking mechanism (100) for heavy equipment having a first structure moveable relative to a second structure, the locking mechanism having an actuator mechanism (125), coupled to one of the first structure and the second structure, operable between a deployed position and a retracted position, a biasing member, a carriage member (110) operable between a restricted position, in response to the actuator (125) being in the retracted position, and an extended position. The biasing member (120) is configured to bias the carriage member toward the extended position in response to the actuator mechanism being in a deployed position and the carriage member is configured to prevent relative movement between the first structure and the second structure in the extended position.
摘要:
A device for limiting the rotational range of a swiveling arm, comprising a discoidal reaction element (1) adapted to be connected to an element of said swiveling arm so as to integrally turn with said swiveling arm, and further comprising at least a limiting element (2) adapted to cooperate with at least an abutting fixed element (6), said limiting element (2) being reversibly constrainable in any circumferential position along the external perimeter of said discoidal reaction element (1), in order to determine a limiting angle of the rotational range of said swiveling arm, wherein said discoidal reaction element (1) comprises an upper face and a lower face, and wherein said limiting element (2) comprises a reversible junction (4) adapted to clamp said upper face and said lower face in a same circumferential position.
