Abstract

A twistlock device for locking containers on vehicles. A housing with a cylindrical vertical throughbore includes an upper guide section for engaging an opening in a container corner bracket, and a lower mounting section for connecting the device to a vehicle. The mounting section protrudes beyond the side faces of the guide section and the guide section extends beyond the end faces of the mounting section. An axially unshiftable locking bolt is rotatably carried in the bore. The bolt's top end is provided with a hammerhead, and its bottom end is provided with a handle for twisting the hammerhead between a locking position and a release position. The locking position is secured by a releasable locking element. The twistlock can be shipped to a vehicle manufacturer completely preassembled, and is inserted by the vehicle manufacturer in a hole in a vehicle outrigger where it can be simply and easily mounted by welding.
