Abstract: A twistlock for locating and locking a freight container on a container-supporting deck of a vehicle. The twistlock is designed to be welded-in to its operating location on the vehicle deck. The twistlock has a register and a mounting boss which are separate components, such that the mounting boss can be welded-in to a pre-cut hole in the deck as an initially separate component, thus obviating welding-heat-induced distortion of the twistlock. The mounting boss is axially self-aligning in the deck, and the remaining components of the twist lock drop into place.

Abstract: Sail handling apparatus comprises an elongate guide element, e.g. a rod or a cable, located along a path along which a tie locating an edge portion of a sail is required to move during sail handling operations. The tie is attached to the guide element by a load-transfer device comprising a pair of rotatable recessed wheels having a guide member located between them at the periphery of the wheels. When the tie is moved along the guide element it can pass intermediate attachment members supporting the guide element with such members being received in the recesses in the wheels which then rotate with respect to the guide element to pass the attachment members through the load-transfer device. In other embodiments, the load-transfer device forms part of the intermediate attachments for the guide element to enable the sail securing ties to pass such attachment points.
