Wind turbine blade railroad transportation with two axis translation

Abstract

Airfoil transportation using two railcars. A radius arm connects a deck pivot and a bolster pivot, where the deck pivot is coupled to the first railcar to enable arcuate transverse movement of the bolster pivot. A pair of deck stops on either side of the radius arm limit lateral movement of the first bolster pivot. A bolster supports the airfoil and is coupled to the radius arm by the bolster pivot. A wheel assembly under the radius arm carries the weight of the airfoil as it moves laterally. A bolster lock, lock release, and latch operate to hold the bolster in a fixed angular relationship with the radius until the lock release enables rotation at the deck stops positions. The latch holds the radius arm against the deck stop until the bolster returns to the fixed angular position, where the latch releases the radius arm to further translate laterally.
