Definitions
- the present invention relates to a crane having one about an upright axis rotatable revolving stage, one on the turntable about a rocking axis hinged hinged Boom, a guy, on the one hand with the boom and on the other is connected to a Abspannbock, which is parallel to a Wippachse Axis pivotally hinged to the revolving stage and / or on the boom foot, and an adjusting device, in particular-stranding, for rocking up and down of the boom connected to the guy trestle.
- the invention further relates a method for erecting the boom of such a crane.
- the present invention is therefore based on the object, an improved Crane of the type mentioned above, which presents the disadvantages of the prior art Avoiding technology and the latter develops in an advantageous manner.
- the erection of the boom easier, on the other hand, the erection the boom in very steep positions are not hindered.
- this object is achieved by a crane according to claim 1.
- the object is achieved by a method according to claim 8 solved.
- Preferred embodiments of the invention are the subject of Dependent claims.
- the crane is thus characterized by an angle adjustment device by means of which the angular position of the guy truss relative to the boom at erected boom is adjustable.
- This can be used to raise the boom the brace first off the boom back to an erect position swiveled with a relatively large angle between the jib and boom become.
- In this upright position of the guy trestle receives the adjustment or stranding an improved lever arm with respect to the Pivot point of the jib or the jib, causing the erection the boom is relieved from the lying on the ground position.
- the Cantilever As soon as the Cantilever a bit far, preferably at least 45 ° or more, is tipped, can the brace to the boom out into an operating position with comparatively Smaller angle between the jib and boom are pivoted. In this operating position of the jib then the boom can still further be tipped in very steep positions without the guy on the top of the turntable of the crane would get up.
- the angle adjustment device for adjusting the angular position of the guy trestle relative to the boom in a further development of the invention consists of a horreinstellvorraum, by means of which the length of the bracing between Abspannbock and boom can be adjusted.
- the length adjustment can basically be formed differently. It would be conceivable, the point of articulation of the bracing on the boom displaceable form or the bracing as a rope to train and to redirect the gantry and there with a winch or adjustable to a power lift and a cable lock.
- the invention consists of the length adjustment of a in the bracing built-in traction means, by means of which the actual Length of the guy can be changed, i. the bracing can be extended or shortened. In particular, a hydraulic power lift and / or an adjusting bottle to be installed in the bracing.
- said length adjustment device is between the tip of the Tensioning trestles and boom mounted in the bracing.
- the bracing As a result, can be struck firmly on the one hand on the guy trestle and on the other hand on the boom be.
- the adjustment device by means of which the boom is tilted up and down, includes Preferably an adjusting cable, between the superstructure on the one hand and the Abspannbock on the other hand is reeved several times.
- the adjusting device is shortened, whereby the boom pivoted upwards is, with the guy bracket is pivoted synchronously backwards. If the adjustment cable is lowered and thereby the adjusting device extended, the boom is tipped off, whereby the guy truss synchronously pivots.
- the guy is between an erecting position and an operating position adjustable, and with erect Outrigger, wherein in the erection position of the guy trestle a larger Angle to the boom occupies than in the operating position.
- This angle between The jib and boom can be used both in the upright position and in the upright position Operating position are measured differently, on the one hand at different Geometries to achieve optimum leverage and on the other hand the Rocker area of the boom to be sized sufficiently large.
- the guy block in the erect position a Angle of 90 ° or more to take the boom while in the operating position an angle of less than 90 ° to the boom occupies.
- the guy trestle in the erect position about an angle of 100 ° to the boom occupies.
- the crane shown in the figures comprises an undercarriage 1, which has a chassis 2 in the form of a crawler track with two parallel, right and left from each other spaced chains comprises.
- On the undercarriage 1 is an upright Rotary shaft 3 rotatably mounted a superstructure or a revolving stage 4, the carries at its front end a boom 5, on the top in known per se Way a hoist rope runs out.
- the boom 5 is about a substantially horizontal Wippachse 6 tiltable hinged to the revolving platform 4, and indeed at the front end.
- a ballast 7 is arranged on the revolving stage 4, which is the from the Boom 5 counteracts induced moment.
- a brace 8 is fixed, which is at the boom tip and / or between the jib tip and the articulated on the turntable 4 Jib is posted on the boom 5.
- the guy 8 is on articulated the tip of a guy trestle 9, which in the region of the articulation point of the Jib 5 is also pivotally hinged to the turntable 4, and that to an axis parallel to the Wippachse 6 axis of rotation 10.
- a Verstellverseilung 11 is articulated, which is a multi-retracted Has Verstellseil and runs on a Wipptechnikwinde 12, which at the turntable 4 is provided.
- the Verstellverseilung 11 runs between the guy clamp tip and the rear end of the turntable 4 and an associated Ballast and serves the up and luffing of the boom 5. It is understood that in addition to the revolving stage ballast 7, an additional ballast is connected to the revolving stage 4 or can be attached to it. The Verstellverseilung could possibly also be associated with this additional ballast.
- the bracing 8 is a Gazneinstellvorraum 12 in the form of a traction device built-in.
- the length adjustment device 12 can consist of a hydraulic cylinder and / or an adjusting bottle. she forms an adjusting member whose effective length can be changed, thereby in turn, the length of the bracing 8 between guy brace and boom can be changed.
- the brace 9 In the still lying on the floor boom 5, the brace 9 is initially in its forward pivoted to the boom 5 operating position.
- the length adjustment device 12 is in its short position, so that the guy trestle 9 to the boom 5 occupies an angle of less than 90 °, in the drawn embodiment is approximately between 70 ° and 80 °.
- the Verstellverseilung 11 In this position the Verstellverseilung 11 has a relatively unfavorable lever arm 13, as figure 1 shows.
- the length adjuster 12 To the lever arm 13 with respect to the rocking axis 6 and the pivot axis 10, the length adjuster 12 will then be in its long position brought, whereby the Abspannbock 9 pivoted away from the boom 5 to the rear becomes, as Figure 2 shows.
- the guy has 9 a larger angle to the boom 5, in the illustrated embodiment is more than 90 °, in particular about 100 °.
- the Verstellverwickung 11 has a better, i. longer lever arm 13 with respect to the pivot axes of the boom 5 and des Abspannbocks 9, so that the introduced by the Verstellverseilung 11 forces exert on the boom 5 a larger torque.
- the boom 5 can thereby be erected with less force in the Verstellverseilung 11.
- the boom 5 is initially erected so far until the guy truss 9 just before queuing at the top of the revolving stage 4 or the ballast 7, as shown in FIG. 3.
- the boom 5 is then the Principalneinstellvorraum 12 moved to its short position.
- the bracing 8 is thus shortened, whereby the guy truss 9 relative to the boom 5 is pivoted.
- the figure 4 shows, the angle between Abspannbock 9 and boom 5 according to smaller, preferably less than 90 °.
- the boom 5 can be further tapped without that the guy trestle 9 rests against the revolving platform upper side or the ballast 7.
