Abstract
Official abstract text for this publication.
The invention relates to a folding suspended ballast guide for a crane having suspended ballast comprising two lattice pieces pivotably connected to one another, wherein in an inwardly pivoted position of the lattice pieces, one of the lattice pieces is at least partially arrangeable in the other lattice piece. The invention is further directed to a crane having a corresponding suspended ballast guide.
First claim
Opening claim text (preview).
The invention claimed is: 1. A folding suspended ballast guide ( 1 ) for a crane ( 100 ) having suspended ballast ( 2 ), and comprising two lattice pieces ( 11 , 12 ) directly pivotably connected to one another about a pivot axle ( 503 ), wherein in an inwardly pivoted position of the lattice pieces ( 11 , 12 ), one of the lattice pieces ( 12 ) is at least partially arranged within the other lattice piece ( 11 ), and in an elongated position, the lattice pieces ( 11 , 12 ) only overlap one another in a region ( 13 ) of the axle ( 503 ), wherein one ( 11 ) of said two lattice pieces ( 11 , 12 ) is arranged to be pivotally mounted ( 104 ) upon a slewing platform ( 102 ) and the other ( 12 ) of said two lattice pieces ( 11 , 12 ) is arranged to suspend the ballast ( 2 ) therefrom, and upon inward pivoting, the lattice piece ( 12 ) arranged to suspend the ballast ( 2 ) is at least partially arranged within the lattice piece ( 11 ) arranged to be pivotally mounted ( 104 ) upon the slewing platform ( 102 ). 2. A folding suspended ballast guide ( 1 ) in accordance with claim 1 , wherein at least one of the lattice pieces ( 11 , 12 ) has a C-shaped cross-section, with the other one of the lattice pieces ( 11 , 12 ) being arranged at least partially between the limbs of the C-shaped cross-section in the inwardly pivoted position of the lattice pieces ( 11 , 12 ). 3. A folding suspended ballast guide ( 1 ) in accordance with claim 1 , wherein at least one of the lattice pieces ( 11 , 12 ) is designed with an open profile. 4. A folding suspended ballast guide ( 1 ) in accordance with claim 1 , wherein at least one overhung pin ( 500 ) is provided for coupling the suspended ballast guide ( 1 ) to a derrick guying ( 501 ) of the crane ( 100 ). 5. A folding suspended ballast guide ( 1 ) in accordance with claim 4 , wherein the at least one pin ( 500 ) is arranged further away from the longitudinal axis of the suspended ballast guide ( 1 ) than the laterally outermost regions of the lattice pieces ( 11 , 12 ). 6. A folding suspended ballast guide ( 1 ) in accordance with claim 4 , wherein the at least one pin ( 500 ) is arranged at a widened section of one of the lattice pieces ( 11 , 12 ) that is wider than other sections of the same lattice piece ( 11 , 12 ). 7. A folding suspended ballast guide ( 1 ) in accordance with claim 1 , wherein the lattice pieces ( 11 , 12 ) are designed as separable for transport purposes. 8. A folding suspended ballast guide ( 1 ) in accordance with claim 1 , wherein a continuous axle ( 503 ) is provided for a coupling of the lattice pieces ( 11 , 12 ) to one another. 9. A folding suspended ballast guide ( 1 ) in accordance with claim 1 , wherein two overhung pins are provided for the coupling of the lattice pieces ( 11 , 12 ) to one another. 10. A crane ( 100 ) having at least one folding suspended ballast guide ( 1 ) in accordance with claim 1 .
