Davit systems are most often used to lower an emergency lifeboat to the embarkation level to be boarded. Davits can also be used as man-overboard safety devices to retrieve personnel from the water. The lifeboat davit has falls (now made of wire, historically of manila rope) that are used to lower the lifeboat into the water.
Steering Linkage: Idler Arm. An idler arm is used in a parallelogram type steering system. Today's vehicles typically have either a parallelogram or a rack and pinion steering system. Parallelogram systems use a gear box with a pitman arm connected to the center link.tâs through the pitman arm that the gear box turns and moves the steering linkage. The parts include the pitman arm, center link, idler arm, and the two tie rods. The idler arm is designed to keep the center link parallel to the road surface, while allowing the link to swivel both left and right.
