摘要： A crane boom and luffing jib assembly have an offsetting link to allow the luffing jib to fold back and under the main boom for assembly of the boom and luffing jib assembly on a construction site where the entire length of the boom and luffing jib cannot be laid out during assembly. A method of assembling the crane boom and luffing jib comprises the steps of assembling the luffing jib and boom, the luffing jib pivotally attached to the jib connection pivot, the luffing jib folded back and under the boom along a ground surface, the hinged connection allowing neutral axis of the jib boom section to be offset relative to the boom connection pivot; attaching the boom to a crane; raising the boom top upwardly, allowing the jib top to travel along the ground surface until the luffing jib is lifted off the ground surface; causing the jib boom section to be aligned with the jib connection pivot; and inserting hinge pins into the hinged connection to lock the jib boom section in axial alignment with the jib connection pivot. wherein the luffing jib is initially folded back and under the crane boom.

摘要： A backstay spreader attachable between a pair of backstay sections on a crane includes first and second members each having a backstay section connector at a first end and a pivoting joint connector at a second end, the pivoting joint connectors being used to hold the first and second members together with a pivotal connection and each having an extending portion extending away from the pivotal connection, with an angle between the extending portions. The backstay spreader also includes an actuator mounted between the pivoting joint connectors. The actuator controls the angle between the extending portions of the two pivoting joint connectors, which defines an angle between the first and second members. When the actuator forces the two extending portions towards each other, the first and second members pivot around the pivotal connection to force the first and second backstay sections further apart from one another, and when the actuator allows the two extending portions to pivot away from each other, the first and second members pivot towards each other, allowing the backstay sections to come closer together.

摘要： A crane includes first and second column segments. At least a first, third and fifth connector are located on the first segment, respectively mating with at least a second, fourth and sixth connector on the second segment. Each of the connectors includes at least a first extension having a through-hole positioned in the extension such that the through-holes of mating connectors are aligned when the column segments are aligned. A first pin fits tightly through the through-hole of the first extension on the first connector and the through-hole of the first extension on the second connector to hold the first and second connectors together. A second pin fits loosely through the through-hole of the first extension on the third connector and the through-hole of the first extension on the fourth connector to hold the second and fourth connectors together. The connectors also include a compressive load bearing surface.

摘要： A crane has a boom with a boom segment connection system. The boom includes at least a first and second boom segment each with a longitudinal axis 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 on the second end of the first segment respectively mating with at least one second connector on the first end of the second segment. The first and second connectors each include at least one extension having a through-hole there through. The through-hole has an axis perpendicular to the longitudinal axis and positioned in the extensions such that all through-holes of mating first and second connectors are aligned when the boom segments are aligned. In one aspect of the invention, the first connector includes a first alignment surface and the second connector includes a second alignment surface that engages with the first alignment surface such that when the first and second alignment surfaces are fully engaged, the through-holes through the extensions in the connectors are aligned such that a main pin can be inserted through the through-holes of all extensions in the first and second mating connectors even if the boom segments are not axially aligned. In another aspect of the invention, the connectors include stop surfaces, and the placement of the stop surfaces on the connectors is such that, when identical boom segments are positioned such that a main pin can be inserted through the through-holes in the extensions of the connectors on some chords of the boom segments, the stop surfaces cooperate to align the through-holes in the extensions of the connectors on other chords when the stop surfaces contact one another.

摘要： Apparatus for packaging a fiber optic device along with electronic and opto-electronic components upon a printed circuit board. Bend members having arcuate shaped guide surfaces for directing fibers between various components are strategically mounted upon the top surface of the board. Passive fiber optic components are also mounted upon support means between bend members so that the fibers entering and exiting the passive component run tangent to the bend radius of the bend members. The radius of curvature of the bend members is within the bend tolerance of the fibers used in the device. The bend members and support members are formed of a material having a thermal coefficient of expansion that is about equal to that of the board material whereby thermally induced stresses on the board mounted components are minimized.

摘要： Material usage tracking systems for monitoring and optimizing usage of stretch film on a stretch wrapping machine is provided. A system includes a rotary encoder collar securable to a pre-stretch roller of a stretch wrapping machine and a proximity sensor securable proximate to the rotary encoder collar. Upon installation, the proximity sensor measures the revolutions of the pre-stretch roller when the stretch wrapping machine is wrapping a product or pallet. The system also includes a controller in communication with the proximity sensor. The controller converts the revolutions of the pre-stretch roller to measurements of the amount of stretch film pulled off a film roll in the stretch wrapping machine based on data received from the proximity sensor. Different uses for the data collected by the material usage tracking system and different ways of presentation of the data are also provided.
