Product Introduction
A crane container spreader is a core equipment specifically designed for loading, unloading, and transporting shipping containers. It is typically mounted on port quay cranes, yard cranes (RTG/RMG), or mobile cranes. By engaging and locking onto the corner castings at the top of containers, it ensures secure lifting and handling, serving as a critical tool for efficient operations in container logistics systems.
Types of Container Spreader
Fixed Spreader
Designed for a single container size (e.g., 20-foot or 40-foot), featuring a simple structure but limited flexibility.
Telescopic Spreader
Adjustable length (e.g., 20–40 feet or 40–45 feet) to accommodate multiple container sizes. The most widely used type in general operations.
Rotating Spreader
Equipped with horizontal rotation capability to adjust container orientation, ideal for complex yard layouts or railway handling.
Side-Shifting Spreader
Enables lateral movement for precise alignment, suitable for confined spaces or high-precision handling tasks.
Tiltable Spreader
Allows containers to tilt at specific angles, designed for specialized cargo (e.g., liquid tank containers).
Fully Automated Spreader
Integrated with intelligent control systems for automatic container size identification and locking, primarily used in automated terminals.

Product Details
Components of Container Spreader and Their Functions
Main Frame
Function: Supports the entire structure and bears the container's weight, typically fabricated from high-strength steel.
Twistlock Mechanism
Function: Hydraulically or mechanically driven to lock onto the container's corner castings, ensuring secure lifting and transport.
Telescopic Mechanism
Function: Electrically or hydraulically powered to adjust the spreader length for compatibility with different container sizes (only available in telescopic spreaders).
Alignment Guide
Function: Facilitates rapid positioning between the spreader and container, minimizing manual adjustment time.
Hydraulic/Electrical System
Function: Provides power and controls the twistlock engagement, telescoping, rotation, and other operational functions.
Control System
Function: Manages spreader movements; modern systems often integrate remote control or automated modules.
Safety Devices
Function: Includes load sensors, twistlock status monitoring, and emergency braking systems to prevent accidental disengagement or drops.
