摘要： A quick-connect system is disclosed for sectional boom members for cranes and the like. The sectional boom members comprise chords for carrying compressive loads, each chord terminating in an end configured to abut against an end of a chord of an adjacent sectional boom member. The quick-connect system comprises at least one easily alignable connector secured to the ends of at least one of the chords, the connector comprising a compressive load bearing surface intersected by the intersection of the vertical and horizontal neutral axes of the chord to which the connector is attached.

摘要： A ring for supporting a lift crane includes at least two ring segments each having two ends, the ends of the ring segments comprising at least one horizontal plate and at least one vertical plate. The horizontal plates and the vertical plates of adjacent ends of the ring segments are disconnectably secured to one another to form the ring support. In a preferred embodiment, the horizontal plates are connected by a vertical pin and the vertical plates are connected by a horizontal pin.

摘要： An apparatus and method for isolating the end of a segment of pipe, which includes a substantially cylindrical body, having first and second ends, and a circumference slightly less than the inner diameter of the pipe segment; a pair of spaced apart inflatable seals positioned around the wall of the body; means for introducing a fluid into the inflatable seals through separate lines under sufficient pressure so that the inflatable seals are inflated against the wall of the pipe segment defining an annular space between the inflated inflatable seals; a line for introducing a fluid into the annular space under pressure to test the integrity of the seal between the inflatable seals and the pipe wall, and having a dual function to capture fluid which may have entered the annular space as a result of a inflatable seal failure; a line through the body for allowing fluid to flow through the line at predetermined times and pressures; and a plurality of bolts on the first end of the body which would engage the inner wall of the pipe in order to provide a secure engagement between the body and the pipe in the event of high unexpected pressure within the pipeline.
摘要翻译：一种用于隔离管段的端部的装置和方法，其包括基本上圆柱形的主体，其具有第一和第二端以及略小于管段内径的圆周; 围绕身体的壁定位的一对间隔开的可充气密封件; 用于在足够的压力下通过分开的管线将流体引入所述可充气密封件的装置，使得所述可充气密封件相对于所述管段的壁膨胀，从而限定所述膨胀的可充气密封件之间的环形空间; 用于在压力下将流体引入环形空间以测试可膨胀密封件和管壁之间的密封件的完整性的线，并且具有双重功能以捕获由于可膨胀的密封件而可能已进入环形空间的流体失败; 通过本体的线，用于允许流体在预定时间和压力下流过管线; 以及在主体的第一端上的多个螺栓，其将与管道的内壁接合，以便在管道内的高意外压力的情况下提供主体和管道之间的牢固接合。
