<p>A crane (10) has a boom (50) with a boom segment connection system. The boom (50) includes at least a first and second boom segment (53,54) each with a longitudinal axis (41) and a first and second end, the second end of the first segment being coupled to the first end of the second segment, and at least one first connector (70) on the second end of the first segment respectively mating with at least one second connector (80) on the first end of the second segment. The first and second connectors (70,80) each include at least one extension (71-73, 81-82) having an aperture there through. The aperture has an axis perpendicular to the longitudinal axis and positioned in the extensions such that all apertures of mating first and second connectors (70,80) are aligned when the boom segments are aligned (53,54).</p> |
