Crane Boom

A crane boom is the load-bearing structural member that extends from a crane and positions suspended materials, making it central to lifting capacity, reach, and stability in engineering. It operates as a cantilevered or lattice structure, transferring forces from the load through the boom, joints, and supporting frame while hydraulic cylinders, wire ropes, or mechanical systems control its angle and extension. Engineers analyze bending, compression, buckling, and dynamic loads to select suitable materials and dimensions and to maintain safe operation. Crane booms are used in construction, manufacturing, offshore operations, and material handling, where their design directly affects lifting performance, workspace coverage, and structural safety.

Methods for Performing Crosses in Setaria viridis, a New Model System for the Grasses

0 Views •

Cited by 31 •

2013

We have developed a methodology for performing crosses in Setaria viridis (S. viridis). The method involves pruning the panicle prior to a hot water treatment to kill viable pollen. Crosses are performed following a well-controlled growth regime and typically result in the recovery of 1 to 7 cross-pollinated seed/s per panicle.
