Introduction

Application Scenario

Advantages

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

Used with container cranes (STS, RTG, RMG), straddle carriers, and reach stackers in ports, container yards, and railway terminals for loading, unloading, and transporting 20ft and 40ft standard containers.

ADVANTAGES

Telescopic Design: Automatically adjusts to handle both 20ft and 40ft containers efficiently.
Twin-Lift Capability: Option to lift two 20ft containers simultaneously, doubling handling efficiency.
High Safety: Equipped with reliable twist locks, mechanical/electrical interlocks, and anti-drop protection.
Durable & Lightweight: High-strength steel structure reduces dead weight while ensuring long-term durability.
Smart Options: Available with integrated weighing systems, auto-centering, and anti-sway sensors.
