Problems solved by technology

[0004] If the load-bearing capacity is to be further increased, truss blocks with larger cross-sections are required, which further makes road transport difficult
[0005] A conventional truss block is known from DE 20 2008 004 663 U1, but in which greater material consumption is required
[0006] DE 10 2013 205 173 A1 describes a truss block, but its assembly requires greater expenditure

Embodiment Construction

[0056] figure 1 A perspective view of two interconnected truss block elements 1 , 2 according to the invention is shown. Here, each truss block element 1 , 2 has a first chord 11 , 21 and a first filling rod 13 , 23 connected to the first chord 11 , 21 , said first filling rod being connected to said first chord 13 , 23 . The diverging ends of one chord 11 , 21 are fixedly connected to the second chord 12 , 22 . At least one second charging rod 14, 24 extends perpendicularly from the plane formed by the first chord 11, 21 and the second chord 12, 22, said at least one second charging rod in relation to the first chord 11, 22 The distal end of 21 includes fasteners 15,25. The fastener is detachably connected to the fastener 16 , 26 provided on the second chord 12 , 22 . This results in a lattice block of the crane jib which, in its rectangular cross-section, has a chord 11 , 12 , 21 , 22 at each corner of its cross-section. Furthermore, on the outer side defined by the two ...

Abstract

The invention relates to a truss block component for a crane jib, including a first truss block component and a second truss block component, each of the first truss block component and the second truss block component includes a first chord member extending substantially parallel to the longitudinal direction of the truss block component; a second chord member extending substantially parallel to the longitudinal direction of the truss block component; a first loading bar fixedly connected to the first chord member and the second chord member and preferably extending in a plane defined by the first chord member and the second chord member, a second loading bar is fixedly connected to the first chord member and protrudes from a plane defined by the first chord member and the second chord member, and the second loading bar having a fastener for detachable attachment at an end thereof away from the first chord member.

Description

technical field [0001] The invention relates to lattice blocks and lattice block elements for crane booms. This is a novel lattice block for a crane jib, which can be used to manufacture at least two different variants of the crane jib. It is conceivable here that such a crane jib essentially consists only of a plurality of lattice block elements according to the invention, but it can also consist only partly of lattice block elements according to the invention while the remainder is constructed from other types of elements. become. Background technique [0002] Here, the crane jib of, for example, a mobile crane is a lattice jib comprising a plurality of lattice blocks. Here, the lattice jib of the mobile crane is usually not erected until it has been transported to the point of use. Theoretically, even fly jibs or booms in a truss-like embodiment can be realized by the truss blocks according to the invention. The fly boom can be designed as oscillating, tilting or fixe...
