The Deck Socket DF-31 makes the Dovetail Twistlock BF-11 and the U-Frame Lashing Eye LP-91-45 removable. When they are not needed, the deck of a ship, pontoon or platform stays free from protruding parts. The DF-31 is made of SCW480 cast steel and has a tested breaking strength of 500 kN (approx. 50 t).
Suitable for BF-11 Twistlock and LP-91-45 Lashing Eye
The BF-11 twistlock slides into the deck socket from the side and secures a container. The same deck socket also takes the U-Frame Lashing Eye LP-91-45 (36 t), for securing machinery or steel structures.
Breaking strength 500 kN
The DF-31 is tested to a breaking strength of 500 kN and a shear load of 420 kN. This makes the deck socket suitable for offshore and maritime applications. The DF-31 is not suitable for road transport, which requires twistlocks with a locking mechanism.
Fitting and inner angle
The DF-31 is welded onto a steel surface, such as a ship’s deck, pontoon or platform. The cast steel frame is blasted and primed, and the primer does not need to be removed before welding. The standard inner angle is 45°, with 55° available on request. A container requires four deck sockets, one per bottom corner. They are not all welded in the same direction, but partly in opposite directions. Once a container is in place, it can no longer slide sideways out of the deck sockets.
Technical data and drawings available
For dimensioning and integration into structures, technical drawings are available in PDF and 3D STP format, for use in CAD software.
