A twistlock assembly for securing a cargo member to a cargo receiving arrangement, the twistlock assembly comprising:
- a base member;
- a twistlock adapted to be at least partially inserted into an opening of a cargo member, the twistlock adapted to assume an unlocked position and a locked position, wherein in the locked position the cargo member is prevented from being disconnected from the base member;
- and
- a permittance assembly comprising a first spring portion and a second spring portion on an opposite side of the twistlock as the first spring portion, the first and the second spring portions adapted to receive and be compressed by at least a portion of a load applied by the cargo member;
- wherein the permittance assembly is configured to:
- allow rotational movement of the twistlock between the unlocked position and the locked position while the load applied by the cargo member to the permittance assembly is greater than or equal to a predetermined threshold load, and
- prevent rotational movement of the twistlock from the unlocked position to the locked position while the load applied by the cargo member to the permittance assembly is less than the predetermined threshold load.
