Gantry crane beam of dihedral section - with ridge lowermost and joined to profiled section supporting load
Реферат: The gantry beam is of dihedral section, the ridge (C) being lowermost and joined to the profiled section (4, 4a) from which the load is suspended. Its section can be that of an isoscales triangle, with the apex downwards and pendulum-mounted in a double bearing, with stops to limit the amount of swing on the bearing. The span can be adjustable by means of bolts sliding in C-section rails. The double bearing can be formed by a false bearing fixed to the beam and on which the bearing proper can rock, carrying the slewing hoist block.
