Definitions
- the invention relates to a ring lift crane according to the preamble of patent claim 1
- a genussente ⁇ der ring lift crane is known from DE 199 14 195 A1.
- This well-known Ri ⁇ gliftkran is provided with a stand-up ring that forms a circular carriageway and has several interconnectable segments, within which an undercarriage is arranged, which has an upper carriage rotatably connected to it and has several winches as well as two bridge girders located at a parallel distance from one another, in two opposite end regions are each provided with an adapter and can be bolted and deboled to the superstructure via cross members.
- the adapters are supported on the circular carriageway of the ring by means of rollers arranged in the end region of the adapter, the center of the ring or the undercarriage forming the axis of rotation and the rear
- An adapter for receiving a counterweight and the front adapter for receiving an articulated boom having at least one main boom is designed in the form of a lattice mast and means are provided for generating the rotary movement of the ring lift crane and the undercarriage is connected to different sections of the ring via stiffening struts.
- This known lift lift crane is limited in terms of its lifting capacity, since it cannot transmit larger forces.
- the object of the invention is to provide a ring lift crane of the generic type, the lifting capacity of which can be significantly increased in a simple manner
- a lattice mast component (main boom, auxiliary boom mast, luffing support) there is a lateral stiffening which extends at least over half the length of the lattice mast component front adapter and its head end is firmly connected to an element of the main boom
- the lateral stiffener extends over the entire length of the main boom, so that the head end of the stiffener is firmly connected to the head piece of the main boom.
- the proposed principle The arrangement of a lateral stiffening is also advantageous for other lattice boom components such as mast, auxiliary boom and luffing support.
- the lateral stiffening consists of at least one guy element that is spaced right and left and parallel to the respective one Lattice tower component arranged and connected to the respective lattice tower element in certain via connecting elements
- the tensioning element is connected to the lattice mast element preferably as an isosceles triangle, the distance between the guy element and lattice mast element being at least half the width of the lattice mast element Depending on the design of the overall construction, the distance can also correspond to 2-4 times the width
- the proposed arrangement leads to a stiffening of the respective lattice boom component, preferably the main boom, in both sides, whereby the arrangement can be subjected to tensile and compressive loads when using rods or pipes as anchoring element Masts as a double mast, the foot pieces of which are connected in an articulated manner to the front adapter.
- the same also applies to a combination double main boom without lateral stiffening in conjunction with an auxiliary boom which is provided with a lateral stiffener
- Figure 1 is a perspective view of a trained according to the invention
- Figure 2 is a partial front view of the main boom Figure 3 on an enlarged scale the head area of the main boom
- a ⁇ bi ⁇ du ⁇ g to the adapter Figure 5 is a plan view of the Ri ⁇ giiftkranes without boom
- Figure 1 shows a perspective view of an embodiment of a ring lift crane designed according to the invention. It has a stand-up ring 2, which is composed of individual segments (not shown here). Inside the ring 2 there is an undercarriage 3 on which a rotatable one
- Superstructure 4 is mounted. Several winches 7, 8 are arranged in a row on the superstructure 4 (FIG. 5).
- the upper carriage 4 is connected via cross beams 9, 10 to two bridge beams 1 1, 12 extending parallel to one another and extending over the ring 2.
- An adapter 13, 14 is provided in each of the two end regions of the two bridge supports 11, 12, which are supported on the circular path of the ring 2 by means of rollers 16, 16 ', which are only indicated here.
- the center 15 of the ring 2 or the undercarriage 3 forms the axis of rotation for the superstructure 4.
- the adapter 13 on the left in FIG. 5 serves to accommodate a main boom 17 and in this exemplary embodiment a double mast 18, 18 '. Alternatively, a single mast could also be used be provided with lateral stiffening
- the articulation points 19, 19 'for the main boom 17 and the articulation points 20, 20', 21, 21 'for the double mast 18, 18' are shown in FIG. 5 on the adapter 13 on the left.
- the adapter 14 on the right is designed to accommodate the counterweight 22, 22 '.
- the boom in this embodiment consists of the already mentioned main boom 17 and the double mast 18, 18 '.
- the double mast 18, 18 ' is on the one hand via a long changeable guy 23 with the head piece 24 of the Main boom 17 and on the other hand each connected to the counterweight 22 via a fixed guying 25, 25 '.
- the main boom 17 is provided with a lateral stiffening (FIGS. 2-4). This consists of a chip removal element 26, 26 'which
- Verbi ⁇ dungseleme ⁇ te 27,27 ' is connected to the respective grid element 28 of the main boom.
- the two connecting elements 27, 27 ' form an isosceles triangle with the cross strut 29 arranged on the grid element 28.
- the head-side end 30, 30 'of the lateral stiffening is connected to the head piece 24 of the main boom 17.
- the foot end 31, 31 ' is with the front
