Suitable for port and ship container handling operations
This product is a heavy-duty semi-automatic spreader, specifically designed to meet the lifting requirements of 20-foot and 40-foot international-standard containers, compatible with single-hook or double-hook crane booms. It features a simple structure and reliable operation, making it particularly suitable for port environments with moderate operation frequency but high stability requirements.
Structural Features of our semi-auto spreader
Mechanically Actuated Twist-Lock System (No Hydraulics / No External Power)
The spreader employs a purely mechanical twist-lock mechanism, which is triggered solely by the vertical motion of the semi-auto spreader relative to the container. Locking is achieved upon landing on the container, while unlocking occurs automatically during lifting. This design eliminates the need for hydraulic or electric power sources, greatly reducing system complexity, potential failure points, and long-term maintenance costs. It also enhances reliability in harsh outdoor environments where the power supply may be inconsistent.
Rigid Fixed-Frame Construction
The semi-auto spreader features a robust fixed-frame structure that is directly suspended from the crane via a bridle sling or spreader rigging system. This configuration provides high structural rigidity and stability during operation, making it particularly well-suited for repetitive lifting tasks such as loading and unloading containers on vessel decks or at quayside terminals. The rigid design also minimizes sway and improves positioning accuracy.
Standardized Container Interface
All interface dimensions and twist-lock positions are designed in strict accordance with ISO standards for freight containers. As a result, the spreader is compatible with standard ISO container types without requiring any structural modifications. Operators can quickly deploy the equipment for immediate use, reducing downtime and simplifying fleet integration across different handling sites.
