Product description Semi-Automatic Twistlock IF-56
The Semi Automatic Twistlock IF-56 has been specially developed to quickly and securely anchor two vertically stacked sea containers. This semi-automatic twistlock is distinguished by the fact that it automatically locks when placed in a ISO 1161: 1984 corner casting. The yellow point always points upwards. Locking when placing is done automatically, but when disconnecting the orange button with stainless steel cable must be pulled. The IF-56 can be mounted in the corner of the top and bottom container. In total, four (semi-automatic) twistlocks are required to connect two sea containers.
In terms of application, the Semi Automatic Twistlock IF-56 is very similar to the IF- 51 Intermediate twistlock . Both form a solid lock between two sea containers. Still, there are two important differences. First, the IF-56 automatically locks when placed on another container. With the IF-51 the handle must be manually afterwards converted. The application of the semi-automatic twistlock IF-56 generally results in a faster process.
Placing twistlock at top of container
When the four semi-automatic twistlocks are placed at the top of a container, another container can be positioned on top of it. The special shape of the yellow tip turns when the weight of the container is completely on the twistlock. The built-in spring is under tension. As soon as the yellow tip of the Semi Automatic Twistlock IF-56 is completely in the corner of the container, the counter pressure is released and the yellow tip returns to the locked position.
Placing twistlock at bottom of container
Placing a Twistlock IF-56 at the bottom of the container (to be placed) works in a similar way. The yellow tip of each twistlock has already been manually applied and secured in the corner casting from the top container. The four twist locks lower with the galvanized point into the corner pieces of the bottom container. The galvanized point at the bottom of the twistlock rotates due to the twisted shape and the weight of the container. The built-in coil spring is put under tension. Once the container is fully seated, the bottom tip will snap back to its original position and the two containers are firmly anchored together.
Unlock top container
The twistlock can easily be unlocked by pulling the orange button backwards and locking it upwards in the slot (photo 2) Tightening the stainless steel cable ensures that the interior turns. This also changes the angle of rotation of both points on the top and bottom of the IF-56. The cable can then be secured in two positions: at the bottom and at the top (towards the yellow point). By pulling and securing the cable in the top slot, the insert rotates and the yellow tip is in neutral position. The top container is thus no longer locked and can be lifted. The four IF-56 twistlocks remain in the bottom container. If desired, another container can be anchored in the same location.
Unlock bottom container
If the twistlocks have to remain attached to the top container when splitting the coupled containers, the stainless steel wire rope can be secured in the bottom groove (photo 3) The yellow point remains locked and the (galvanized) bottom point comes into neutral position. In this situation, the lifted container has four semi-automatic twist locks at the bottom. In addition to the slit at the bottom, there is also a notch on the left side of the orange button in this design. This notch serves the same purpose and can be useful in a situation where space is limited. For example if the twistlock is attached directly to the deck, for example in a raised deck socket or stanchion, (photo 4)
The various uses make this semi-automatic twistlock multi-purpose. A disadvantage is that working with this twist lock requires some explanation. In addition, compared to regular twist lock, take a closer look at complying with the necessary safety procedures. With these conditions in mind, the IF-56 is a good option for loading and unloading sea containers as quickly as possible.
