Abstract
A longitudinally divisible crane boom segment includes at least a first and a second section that are easily nested together for transport. The sections each include at least one chord member, at least one bracket attached to the section, and a plurality of partial lacing elements. Each partial lacing element has a first end permanently attached to the at least one chord member and a second end. The second end of at least one of the plurality of partial lacing elements of the first section is connectable to a bracket attached to the second section to hold the sections in a nested fashion.
Claims14
A method of nesting the sections of a longitudinally divisible crane boom segment for transport comprising the following steps:
- a) providing a crane boom segment longitudinally divisible into at least a first and second section, each of the sections comprising at least one chord member and a plurality of partial lacing elements having a first end permanently attached to the at least one chord member and a second end attached to a partial lacing element of the other of said sections, at least the first section having at least one bracket thereon;
- b) disconnecting the second end of the plurality of partial lacing elements of the first section from the partial lacing elements of the second section;
- c) translating one of the sections longitudinally with respect to the other of said sections;
- d) placing the at least two sections in a nested configuration;
- and
- e) connecting the nested first and second sections together by connecting the second end of at least one of the partial lacing elements of the second section to the at least one bracket of the first section.
A method of nesting the sections of a longitudinally divisible crane boom segment for transport comprising the following steps:
- a) providing a crane boom segment longitudinally divisible into at least two sections, each of the sections comprising at least one chord member, at least one bracket attached to the at least one chord member, and a plurality of partial lacing elements each having a first end permanently attached to the at least one chord member and a second end connected to one or more corresponding ends of a plurality of partial lacing elements attached to a chord member of another one of the at least two sections;
- b) disconnecting the second end of each of the plurality of partial lacing elements from the one or more corresponding ends of the plurality of partial lacing elements of another one of the at least two sections;
- c) translating one of the at least two sections with respect to the other one of the at least two sections until the second end of each of the plurality of partial lacing elements of each of the at least two sections may be moved into contact with the at least one bracket attached to the at least one chord member of each of the other of the at least two sections;
- d) moving one of the at least two sections toward the other one of the at least two sections until the second end of the plurality of partial lacing elements of each of the at least two sections contacts the at least one bracket attached to the at least one chord member of the other of the at least two sections;
- and
- e) connecting the second end of the plurality of partial lacing elements of each of the at least two sections to the at least one bracket of the other of the at least two sections.
