Abstract
A fire apparatus includes a chassis, axles coupled to the chassis, a turntable rotatably coupled to the chassis, and an aerial ladder assembly pivotably coupled the turntable. The aerial ladder assembly includes a first ladder section extending longitudinally, a second ladder section extending longitudinally, and a support slidably coupling the second ladder section to the first ladder section such that the first ladder section supports the second ladder section. The support facilitates longitudinal movement of the second ladder section relative to the first ladder section between an extended position and a retracted position. The support is pivotably coupled to the first ladder section.
Claims12
An aerial ladder assembly for a fire apparatus, the aerial ladder assembly comprising:
- a first ladder section extending longitudinally;
- a second ladder section extending longitudinally and selectively repositionable relative to the first ladder section in a longitudinal direction between an extended position and a retracted position;
- a first support coupled to the first ladder section;
- a second support coupled to the first ladder section and longitudinally offset from the first support;
- and
- a third support coupled to the first ladder section and configured to limit downward vertical movement of the second ladder section;
- wherein the first support and the second support slidably couple the second ladder section to the first ladder section, wherein the first support is configured to limit downward vertical movement of the second ladder section, wherein the second support is configured to limit upward vertical movement of the second ladder section;
- and
- wherein the third support is configured to slidably engage the second ladder section when the second ladder section is in the retracted position.
