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) comprises a carbody (12) having movable ground engaging members (14, 16). A rotating bed (20) is rotatably connected to the carbody such that the rotating bed can swing with respect to the ground engaging members. A boom (22) is pivotally mounted on a front portion of the rotating bed. A mast (28) is mounted at its first end on the rotating bed. A backhitch (30) is connected between the mast and a rear portion of the rotating bed. The crane (10) further comprises a movable counterweight unit, at least one hydraulic cylinder, and at least one arm pivotally connected at a first end to the rotating bed and at a second end to the hydraulic cylinder. The arm and hydraulic cylinder are connected between the rotating bed and the counterweight unit such that extension and retraction of the hydraulic cylinder changes the position of the counterweight unit compared to the rotating bed.

摘要： A mobile lift crane (10) comprises a carbody (12) with moveable grounding gauging members (14, 16), a rotating bed (20) rotatably connected about an axis of rotation to the carbody such that the rotating bed can swing with respect to the grounding gauging members, a boom (22) pivotally mounted on a front portion of the rotating bed and a mast (28) mounted at its first end on the rotating bed. The crane (10) further comprises a movable counterweight unit and a counterweight movement structure connected between the rotating bed (20) and the counterweight unit, such that the counterweight unit may be moved to and held at both a forward position and a rearward position. The crane (10) has a total amount of counterweight of at least 250 metric tonne and a maximum rated load moment of at least 6,250 tonne-metres, and the ratio of maximum rated load moment to the total weight of the counterweight is at least 25.

摘要： A connector for a column segment, such as a boom segment, of a crane includes n extensions, where n is a positive integer. Each extension has a first base and an aperture extends through the extension from a first side to a second side. The first connector also includes at least (n+y) plates, where y is selected from the group consisting of (-1, +1) such that the sum of (n+y) is a positive integer. The plate or plates are positioned in and coupled to the extensions in an alternating arrangement. Each plate includes a plate base aligned substantially in a plane with the first base of the extension to form a first connector mounting surface. A plurality of welds couple the plates to the extensions and the fabricated connector is then welded to the column segment. At least one extension is formed of steel having a grain structure elongated in a direction of rolling that is substantially perpendicular to the first base.

摘要： A method of connecting sections of a crane suspension assembly together includes attaching a frame to a member of a first section; connecting a tension member between the frame and a connector used in the assembly; moving the tension member so that the connector pivots about a pin to a position where a second hole in the connector is in alignment with a hole in a second section member; putting a second pin through the hole in the connector and the hole through the second section member; and disconnecting the tension member from the connector. The method may also include attaching a frame with a winch to a section of the crane suspension assembly; connecting a line from the winch to the connector; activating the winch to move the connector so that it pivots about a pivot axis; and securing the connector in its second position.
