Frequently Asked Questions
What are twist locks and stacking pins?
Twist locks and stacking pins are components used to secure shipping containers during lifting, stacking, and transport. Twist locks lock into a container’s corner castings to hold containers firmly in place, while stacking pins and cones help with alignment and stable positioning.
Are twist locks compatible with all ISO containers?
Yes. All our twist locks and stacking equipment are designed to fit standard ISO corner castings, making them suitable for most shipping containers used in transport, storage, and site installations.
What’s the load rating for twist locks?
Load ratings vary by product, but all twist locks and stacking pins are made for heavy-duty use and tested to meet industry standards. Check each item’s specifications or contact us if you need help choosing the right rating for your setup.
Can twist locks be used on lorry beds?
Yes. We stock specialist options such as the Universal Lorry Bed Retractable Twist Lock, designed specifically for securing containers, trailers, and other substantial loads onto flatbed trucks.
What’s the difference between manual and semi-automatic twist locks?
Manual twist locks need to be locked and unlocked by hand, while semi-automatic versions engage automatically when the container is lowered into position. Semi-automatic locks help speed up handling and reduce manual work on busy sites.
When should I use a dovetail twist lock and foundation plate?
Dovetail twist locks and foundation plates are ideal when you need to secure a container to the ground or a fixed base. They’re commonly used for semi-permanent or permanent installations where movement, shifting, or uplift needs to be prevented.
Do I need stacking cones or twist locks for stacking?
Stacking cones are used for quick alignment and positioning, while twist locks provide a secure mechanical lock. For safe, secure stacking, especially at height or during transport, twist locks are recommended, with cones used as an additional guide if needed.
