Definitions
- the invention relates to a crane according to the preamble of claim 1.
- Cranes with rubber-tired chassis are usually equipped with supports (see FIG. 9 ).
- the lifting of loads is usually only possible when the crane stands on the supports.
- Cranes with crawler tracks usually have no supports, but lift loads on the caterpillars and can usually also move with the load.
- caterpillar cranes can also be equipped with supports.
- the most important components of the undercarriage of the Demag CC / PC 3800 are in FIG. 10 shown schematically, wherein the direction of travel is indicated by the arrow 1.
- Four arms 4 extend from the turning center 2 to the caterpillars 3.
- Four supports 5 are fastened to the outsides of the caterpillars.
- Such a crane can be operated standing on the caterpillars as well as standing on the supports.
- FIG. 11 shows an undercarriage similar FIG. 10 , Here the caterpillars are connected to each other via a central piece 6. This center piece is the usual construction for a crawler crane without supports. In the middle of the track carrier is usually enough space. Therefore, the assembly and the bolting of the components is relatively unproblematic.
- the invention has for its object to equip a crane, in particular a mobile crane on narrow-building crawler undercarriage in such a way with supports that an enlarged support base is achieved.
- a crane in particular a mobile crane, consisting of an undercarriage, a superstructure and a boom arranged thereon, wherein the superstructure is connected to the undercarriage via a rotary connection and wherein a plurality of supports are provided on the crane, the serve to increase the support base, which is characterized in that the undercarriage consists of a central piece and on two sides of the center piece of parallel crawler tracks that four supports are provided, which are connected to the undercarriage, wherein the orientation is fixed such that they each enclose an angle of 90 ° with each other, wherein two of the supports in the longitudinal direction of the undercarriage and two are aligned transversely thereto and wherein one of the lateral supports is connected with its underside with the facing crawler track and secured with the top of the centerpiece.
- the arrangement of the supports in the longitudinal direction or transversely to the undercarriage results in a direct power flow. As a result, no avoidable moments occur. The occurring forces and stresses are smaller. Less material is needed. Weight and costs are reduced.
- the connection point of supports to the chassis is always rectangular. This is generally easier and quicker to install than a sloping joint. Also, the space required for the connection is lower.
- the supports are arranged parallel to the caterpillars and perpendicular to the caterpillars and intersect at the center of rotation.
- the concrete design may differ. However, it is true that the ends of the supports are transverse to the direction of travel outside the track and that the supports lie along the direction of travel within the track.
- connection of the supports to the undercarriage can be carried out according to an embodiment in that of the transversely oriented supports at least one is attached directly to the crawler chassis.
- the supports in the longitudinal direction can be attached directly to the center piece, or attached to the centerpiece facing side of the crawler chassis, or to center and crawler chassis.
- the supports can be designed to be telescopic, can be folded upwards or laterally.
- the contact to the support surface producing support cylinders are arranged.
- a particular embodiment, which is advantageous both for stationary cranes and for mobile cranes, is that at least one of the supports is designed as a two-point tilting edge.
- a cross member may be attached to the head of the support and at a distance from each other two support cylinders are provided on the cross member.
- the support cylinders may for example be hydraulically or by means of a spindle drive extendable.
- a further support cylinder may be arranged at the head of the support centrally between the support cylinders arranged on the cross member.
- the support cylinders can - according to another embodiment - be connected at their free ends via ball joints with a support mat and it is possible that one of the cross member arranged support cylinder is rotatably mounted about its longitudinal axis in this, in order to exclude any Verzwfitungs technology.
- the crane has four supports. Seen in the direction of travel shows a support 8 forward and is within the track. A support 9 points to the rear and lies within the track. A support 10 points to the left and is out of the track. A support 11 points to the right and is out of the track. In this arrangement, all columns are claimed as pure bending beam. Also, the central piece 6 and the caterpillars 3 are not subjected to torsion. The connection of the supports 17 to 20 to the caterpillars 11 and to the middle piece 6 happen in each case vertically and in places with sufficient space.
- FIG. 2 shows a crane according to the invention seen from behind.
- the superstructure 12 with boom 13 and counterweight 14 is rotatably connected via a rotary joint 15 with the center piece 6.
- the columns can be relatively long in this arrangement, whereby large moments occur in the supports. Since the left support 10 are passed through the bead 3, the height of the support 10 is limited by the height of the beads.
- the type of connection of the right support 11 removes this restriction.
- the underside of the support 11 is connected to the right-hand caterpillar. The top is struck against the center piece 6.
- the rear support 9 is attached only to the center piece. To reduce the moment in the support, like the front support 8, it can be attached to both the center piece and the caterpillars. Of course, it is also possible to attach the supports 8, 9 only to the caterpillars.
- FIG. 3 shows a further advantageous embodiment.
- a support 16 is designed such that a tilting edge is formed on the support. Based on FIGS. 4 and 5 the advantage is explained.
- FIG. 4 schematically four supports 17 are shown, which are arranged centrally to the center of rotation 2.
- the connecting line 18 between the ends of each two adjacent supports is referred to as tilting edge 18.
- a support 16 FIGS. 4 and 5
- FIG. 6 shows a typical conventional support.
- a hydraulic cylinder 21 is mounted, which is connected via a ball joint 22 with a support plate 23.
- the ball joint ensures that small uneven floors are compensated.
- a support according to the invention must at the end of a Have tilting edge.
- FIG. 7 One possible copy ( FIG. 7 ) consists of a support with a support cylinder 21 and two additional supports 24 which are mounted laterally in the front region of the support beam 20 on a cross member 25. In normal crane operation, the middle support cylinder 21 is used. To activate the additional support edge, the lateral supports 24 are extended. This can be done hydraulically or by spindle drive.
- FIG. 8 Another embodiment shows FIG. 8 , In the front area, two support cylinders 26, 27 are attached to a transverse bar 29. About ball joints they are connected to a support mat 28. To exclude Verzwteilungs theory, one of the cylinder 27 is rotatably mounted in the crossbar 29. When the additional tilting edge is activated, the hydraulic oil is locked in the cylinders. The arrangement is then rigid. In normal crane operation (standard support base), the cylinders are hydraulically balanced so that oil can flow freely from one cylinder to the other. Thus, the support mat is rotatable about a point between the cylinders. This possibility of being able to switch between normal operation and operation with extended tilting edge is not absolutely necessary. However, this ensures that the ground pressure distribution under the support mat 28 is uniform.
