SAFETY DEVICE FOR A CANTILEVERED BEAM AND BOOM ASSEMBLY INCORPORATING THE SAME
摘要
A safety device for a cantilevered beam pivotally mounted adjacent one end thereof to a support surface is adapted to bridge the beam and the support surface and is structured so that when coupled to the beam and support surface, the safety device maintains the beam in a substantially fixed cantilevered condition until a downward force exceeding a threshold is applied to the beam and thereafter controls downward pivoting of the beam.
