<p>A method of assembling a mobile lift crane (10), the lift crane including, during operation, i) a rotating bed (20), ii) a boom (22) pivotally mounted on the rotating bed, iii) a luffing jib (23) pivotally mounted to the end of the boom; iv) a first strut (27) also pivotally connected to the end of the boom, the first strut including a first strut cap (31) having sheaves, and v) a second strut (29) connected to the boom below the connection point of the first strut, the second strut including a second strut cap (31) having sheaves, the method including: a) connecting the first strut with the first and second strut caps reeved with a first line (19), to the end of the boom; b) connecting a second line (119) to an end of the first line, the second line being wound around a rotatable drum (50) mounted on an immobilized drum frame (60); and c) removing the first line to thereby pull the second line through the sheaves to reeve the first and second strut caps with the second line.</p> |
