A heavy-duty lift truck designed to lift and stack shipping containers, with laden models handling loaded containers and empty models handling empties.
Detailed Definition
Container handlers are large counterbalanced lift trucks used at ports, inland terminals, rail yards and container depots. Laden container handlers usually lift with a top-lift spreader whose twist locks engage the four top corner castings of a loaded container. Empty container handlers are lighter machines, often with side-lift spreaders, used to stack empties in depots. Both differ from reach stackers, which use a telescopic boom, and from straddle carriers, which drive over the container. Rated capacity and stacking height vary by model and are shown on the data plate.
Laden versus empty container handlers
The two types are built for different jobs. A laden handler must lift a fully loaded container, so it has a heavier frame, counterweight and spreader rated for loaded boxes. An empty handler moves and stacks empty containers, often several high, and is lighter and less expensive to run. Using an empty handler on a loaded box is unsafe. Check the rated capacity, the load center and the spreader rating together, since all three limit what the machine can lift.
Where they fit in the container flow
At a terminal or depot, the handler moves containers between stacks, rail cars and trucks, including placing boxes onto a chassis for drayage. The pallets inside a container are not touched by the container handler; they are unloaded later at the consignee's dock with forklifts or pallet jacks. For shippers, container handling at the terminal mainly shows up as appointment timing, lift charges and free time, not as a direct pallet handling issue.
Safety around container handling equipment
Container handlers have large blind spots and carry heavy loads high, so terminals separate pedestrians and road trucks from working areas. Drivers waiting for a container are usually required to stay in the cab or a designated safe zone. Follow the terminal's site rules on speed, exclusion zones and communication.

Frequently Asked Questions
How is a container handler different from a reach stacker?
A container handler lifts with a spreader carried on a vertical mast, much like a very large forklift, so it works close to the front of the machine. A reach stacker carries its spreader on a telescopic boom that can reach over a first row of containers to a second or third row. Reach stackers are flexible in tight yards, while container handlers are often used for high stacking along clear rows.
Can a container handler unload pallets from inside a container?
No. A container handler lifts the whole container by its corner castings and is far too large to enter a box. Palletized freight inside a container is unloaded at a dock, ramp or yard using standard forklifts, pallet jacks or container ramps. If you receive containers, plan dock space, unloading equipment and labor for that step, and keep unloading within the free time allowed by the drayage carrier and chassis provider.
