Semi-Automatic Twistlock Dual handle
— The Dual-Handle Design: Uncompromising Reliability in Simplicity —
Product Overview
The dual-handle semi-automatic twist lock—also referred to as a semi-automatic twistlock with dual cables, semi-auto double handle twistlock, or semi-automatic twin-wire twist lock—is designed for securely connecting two shipping containers together. When one container is stacked on top of another, the locking cone engages automatically under the container’s weight. The release is achieved manually by pulling either of the two handles or wires, which disengage the upper or lower cone.
Locking Direction & Operation These semi-automatic container twist locks are the most widely used fastening devices in the container transport industry. Each unit features a durable steel body and a dual-wire release system that locks into the ISO corner casting of a container. This mechanism ensures containers can be safely stacked vertically or positioned side by side, forming a stable and secure connection during handling and transport.
As a professional supplier with over 10 years of industry experience, our company specializes in the production and export of container fittings and securing systems. OLIPORTS semi-automatic twistlock products are made of high-quality alloy steel and tested under strict quality standards, ensuring durability and reliability in marine and railway applications.

Key Features
Note:The release wire, spring, and lock pin wear and anti-corrosion layer should be checked regularly to avoid release failure due to rust and obstruction.
- Automatic Locking System: Automatically engages when inserted into the container corner casting, simplifying operation and saving time.
- Dual Handle (Dual Wire) Design: Two handles or cables allow operation from both sides, ideal for limited working spaces and safe manual release.
- High Strength and Corrosion Resistance: Made of forged or cast steel with hot-dip galvanized surface treatment to ensure long-lasting durability and high load capacity.
- Versatile Compatibility: Engineered to fit standard container corner castings (oval slots, 55° dovetail sockets), they support vertical stacking, horizontal connection, or welding to base frames (weldable models available).
- Weldable & Class Approved: Meets ABS, DNV-GL, CCS, and ISO standards
Application
The Dual Handle Semi-Automatic Twistlock is suitable for a wide range of container transport and handling systems, ensuring safety and stability in various operational environments:
- Maritime Shipping: On container ships, dual handle twistlocks secure containers to the deck or stack them vertically.
- Rail Freight: For intermodal railcars (flatcars designed for containers), these twistlocks fasten containers to the railcar frame.
- Trucking & Road Transport: When containers are loaded onto semi-trailers, dual handle twistlocks connect containers to the trailer’s locking pins.
- Container Yards & Terminals: In storage yards or port terminals, they’re used to stack containers safely for long-term storage.
With its high tensile strength, corrosion-resistant finish, and standardized connection design, this part is trusted by global shipping lines, shipyards, port operators, and marine service providers. By choosing OLIPORTS as your supplier, you ensure reliable performance, compliance with ISO & class society standards, and consistent availability for both scheduled maintenance and large-scale fleet projects.
Recommended Accessories
The dual handle semi-automatic twist lock can be used together with several other container securing components to form a complete locking system for container stacking and transport. These accessories are commonly applied on container ships, trailers, and terminal handling equipment to ensure reliable and safe connection under dynamic load conditions.
- Stacking Cone / Positioning Cone: Stacking cones and twistlocks are an indispensable combination for high-stacking in terminal yards and inside container ship holds.
- Bridge Fitting / Lateral Twistlock: Used to horizontally connect two adjacent containers at their top. Used in conjunction with twistlocks when stacking containers on ship decks to form stable “container walls.”
- Twistlock Base / Bottom Lock: Used to lock containers to the transport carrier when loading onto a ship or truck.
- Lashing Rod / Turnbuckle: When stacking containers multiple tiers high on a ship’s deck, lashing rods connect to the twistlocks in the corner castings of various tiers, forming a massive rigid network.
