Key parts and components of a typical port equipment spreader:

    Frame: The main structure of the spreader that supports and houses all other components. It is designed to securely attach to the lifting machinery.

    Twistlocks: These are locking mechanisms attached to the spreader that engage with the container's corner castings to hold it securely. They can be manually or hydraulically operated.

    Telescopic Arms: These arms can extend or retract to accommodate containers of different sizes. They are a critical part of the spreader's ability to handle various container dimensions.

    Control System: The spreader is controlled by an electronic or hydraulic control system that enables the operator to manipulate the twistlocks and other movements of the spreader arms.

    Hydraulic System: The hydraulic system powers the various movements of the spreader, including the opening and closing of twistlocks and the extension and retraction of the arms.

    Sensors: Sensors and limit switches are used to provide feedback to the control system, ensuring safe and precise container handling. They may monitor factors such as container weight and position.

    Load Cells: Load cells measure the weight of the container being lifted, allowing the spreader to distribute the load evenly and prevent overloading.

    Spreader Headblock: The headblock is the top part of the spreader that connects to the crane's hook or other lifting device. It provides the connection point between the crane and the spreader.

    Locking Pins and Bolts: These are used to secure different components of the spreader, such as the telescopic arms and twistlocks, to ensure safe and stable operation.

    Greasing and Lubrication Points: Proper lubrication is essential for smooth and reliable operation. Spreaders have various points where greasing and lubrication are required to reduce friction and wear.

    Safety Features: Spreaders often incorporate safety features such as emergency stop buttons, anti-collision systems, and overload protection to ensure the safety of both equipment and personnel.

    Maintenance Points: These are designated areas for routine maintenance and inspections, such as access panels for servicing hydraulic components or electrical connections.
