Dovetail foundation

Dovetail twist locks are a key element in ensuring the security and stability of containers during transport. These mechanical devices, made of low-alloy casting steel and painted to resist corrosion, are designed to securely attach containers to transport structures, such as ships, trains and trucks.

Positioning:

The correct position of twist locks is crucial to ensure effective anchoring. Generally, twist locks are positioned in the top four corners of the container, corresponding to the so-called ‘corner castings’. These anchorage points are strategically chosen to evenly distribute the load and resist stress during transport.

There are mainly two types of dovetail bases:

• Single: They have dimensions of 240x160x30 mm and weigh approximately 4 kg. They are ideal for standard applications and offer a secure anchorage point.
• Double: They measure 480x160x30 mm and weigh 7.5 kg. They feature two attachment points 203 mm apart, offering a larger contact surface and wider load distribution. Double bases are often used for applications requiring greater load capacity or to provide additional stability.

Features:

• Shear: 42 ton, to ensure that the lock can handle lateral forces.
• Tension: 50 ton, capable of withstanding separating forces.
• Compression: 25 ton, demonstrating its ability to withstand heavy vertical loads.

Information:

• Compatibility: It is essential to check the compatibility of twist locks with the type of container and the transport structures used.
• Maintenance: Twist locks require periodic maintenance to ensure proper functioning and prolong their lifespan.
• Regulations: The placement and use of twist locks must comply with national and international hazardous goods transport and safety regulations.

Dovetail twist locks are a reliable and secure solution for securing containers. The choice of twist lock type and the correct position of the twist locks are crucial factors in ensuring the stability of the cargo during transport and preventing accidents.
