Introduction

Structural Diagram And Parameter Table

INTRODUCTION

A Container Spreader is a specialized lifting attachment designed for handling ISO standard sea containers. Suspended beneath container gantry cranes, reach stackers, or quay cranes, it utilizes hydraulically or mechanically operated twistlocks at its four corners to engage, lock, and lift containers securely by their corner castings.

APPLICATION SCENARIO

[1] Container terminals – Lifting and stacking containers between ship and yard.

[2] Intermodal rail yards – Transferring containers between railcars and trucks.

[3] Inland container depots – Stacking empty or laden containers for storage.

[4] Port gate areas – Handling container inspection and weighing.

[5] Medium‑sized port cranes – Fixed or manually adjustable spreaders for smaller operations.

ADVANTAGES

1. The main frame of the container spreader has high strength, good rigidity, and light self weight. The main beam of the lifting appliance is made of I-beam steel, and strengthened at the four key lifting points and cantilevers, thereby enhancing the bearing capacity and rigidity of the lifting appliance.

2. The rotary lock adopts a dual positioning device, which prevents the lifting tool from rotating when lifting the container, enhancing safety performance.

3. The horizontal transmission rod of the lifting appliance adopts a four link mechanism, which makes the rotation of the rotary lock smoother and more accurate, thereby further improving the safety of loading and unloading operations.

4. The four corners of the lifting appliance are designed with rounded corners, which will not damage the container during operation.

5. The lifting appliance is equipped with an opening and locking indicator board, which allows the driver to determine the opening and locking status based on the opening and locking indicator board.
