Abstract
Official abstract text for this publication.
A boom section for the boom of a telescopic crane has a lower shell and an upper shell. The lower shell and the upper shell are welded to one another, and the weld seam extends between the lower shell and the upper shell angled in at least one region to at least one section edge of the boom section.
First claim
Opening claim text (preview).
The invention claimed is: 1. A boom section for a boom of a telescopic crane, the boom section having a lower shell and an upper shell, wherein the lower shell and the upper shell are welded to one another, wherein a cross-sectional extent of the lower shell varies relative to a cross-sectional extent of the upper shell along a length of the boom section, and wherein a weld seam between the lower shell and the upper shell extends at least in one region of the boom section at an angle to at least one section edge of the boom section. 2. The boom section in accordance with claim 1 , wherein the lower shell is thicker than the upper shell. 3. The boom section in accordance with claim 1 , wherein the weld seam between the lower shell and the upper shell extends along an entirety of the boom section at a varying angle greater than 0 degrees to the at least one section edge of the boom section. 4. The boom section in accordance with claim 1 , wherein the weld seam between the lower shell and the upper shell extends along a first part of the boom section at a varying angle greater than 0 degrees to the at least one section edge of the boom section. 5. The boom section in accordance with claim 4 , wherein the weld seam between the lower shell and the upper shell extends along a second part of the boom section in parallel with the at least one section edge of the boom section, and wherein the first and second parts of the boom section are contiguous. 6. The boom section in accordance with claim 1 , wherein the weld seam is curved and extends along an entire length of the boom section. 7. The boom section in accordance with claim 1 , wherein the weld seam is curved and extends along only part of a length of the boom section. 8. A boom for a telescopic crane having at least one boom section, the boom section having a lower shell and an upper shell, wherein the lower shell and the upper shell are welded to one another, wherein a cross-sectional extent of the lower shell varies relative to a cross-sectional extent of the upper shell along a length of the boom section, and wherein a weld seam between the lower shell and the upper shell extends at least in one region of the boom section at an angle greater than 0 degrees to at least one section edge of the boom section. 9. A telescopic crane having at least one boom section, the boom section having a lower shell and an upper shell, wherein the lower shell and the upper shell are welded to one another, wherein a cross-sectional extent of the lower shell varies relative to a cross-sectional extent of the upper shell along a length of the boom section, and wherein a weld seam between the lower shell and the upper shell extends at least in one region of the boom section at an angle greater than 0 degrees to at least one section edge of the boom section. 10. A boom section for a boom of a telescopic crane, the boom section having a lower shell and an upper shell, wherein the lower shell and the upper shell are welded to one another, wherein a cross-sectional extent of the lower shell varies relative to a cross-sectional extent of the upper shell along a length of the boom section, and wherein a weld seam between the lower shell and the upper shell extends at least in one region of the boom section at an angle to at least one section edge of the boom section and wherein the telescopic crane is a mobile crane.
