Frequently Asked Questions (FAQs)

What are the primary types of container spreaders used in China?

In China, the primary types of container spreaders include semi-automatic and manual container spreaders. Semi-automatic spreaders are designed for handling 20 ft and 40 ft ISO containers and operate by activating the twistlocks through the process of landing and lifting the spreader by a crane operator, without the need for hydraulic or electric systems. Manual spreaders, on the other hand, require operators to manually hook and unhook the containers using a special rope pull and twist-lock control.

How do semi-automatic container spreaders work?

Semi-automatic container spreaders are engineered to handle ISO containers efficiently. These spreaders are attached to the hooks of cranes such as jib cranes, gantry cranes, or bridge cranes. The twistlocks on these spreaders are activated when the spreader is lowered onto or lifted off the container by the crane operator. This mechanism eliminates the need for any hydraulic or electric systems, making the operation simpler and more reliable.
