As a spreader or spreader is known in the operation of loading stations and port - terminals that lifting equipment with which ISO -genormte containers are handled. They are most often seen on container gantries or straddle carriers .

Usually this is telescopic frames ( '30' 40 20 'or 45') can on the length be set of the container ( spread engl. Casting for "spread") and so to the four upper corner fittings (engl. Corner ) of the container and lock by turning with the twistlocks . Non-adjustable container hoists are also referred to by the term spreader.

Many spreaders are equipped with foldable flippers that align the spreader with the container when it is placed on the free-standing container. The flippers can be folded up and inwards by the crane driver as required, so that containers can still be picked up and set down next to other containers.

Attachments to forklift trucks for picking up containers of various types are also known as spreaders . In addition to the spreaders that grip from above, designs that grip the container from the side are also used for empty containers.

There are also spreaders that can also be used in so-called twin operation ( twin for "twin"). This means that two 20 'containers can be handled at the same time . The twin gap, the distance between the containers, can be adjusted continuously until a total length of 40 'or 45' is reached. Twin operation increases the speed when unloading (unloading) or loading (loading) ships.
