Semi-automatic spreaders are automated loading and unloading equipment that integrates sensor technology, hydraulic drive, or electric servo systems. Its core design concept is to significantly reduce the physical burden and operational complexity of direct manual operation by automating some operating processes (such as dynamic width adjustment and cargo locking). This type of equipment usually retains a manual intervention interface to ensure flexible control capabilities under complex working conditions.
Application Scenarios
Port loading and unloading: At container terminals, semi-automatic spreaders can quickly switch between different container sizes, improving terminal turnover efficiency.
Ship cargo securing: During the cargo lashing process, semi-automatic tensioners automatically apply a preset tension, requiring only monitoring of the equipment status.
Special cargo transportation: When transporting large equipment, such as semi-automatic spreaders, sensors are used to monitor the cargo's tilt angle in real-time and automatically adjust the support point position to ensure safe transportation.

Technical Features of Semi-automatic Spreaders
Automated Control: Precise motion control is achieved through a Programmable Logic Controller (PLC) or sensor network, for example, automatically detecting cargo dimensions and adjusting spreader openings.
Human-Machine Collaboration: Human interfaces (such as remote controls or control panels) are retained, allowing operators to intervene during automated processes to adjust parameters or address exceptions.
Safety Redundancy: Equipped with an emergency stop button and overload protection, some models also integrate a visual recognition system to mitigate collision risks.
