With an articulated pivot trunnion, the SB crane’s frame flexes with uneven terrain. Planetary drives mean the crane will move very smoothly when accelerating or decelerating, which gives the operator very precise control of the load.
Available single-beam gantry cranes can manage loads from 30- 100USt and greater, perfect for single-point picks that include loads such as nacelle hubs. To do the same with a conventional gantry, for example, would need a spreader beam to bring the unit to a single pick point. The single-beam gantry, on the other hand, is ideally suited for this sort of task; the load pivots around one point.
