The most common use of straddle carriers is in port terminals and intermodal yards, where they are used for stacking and moving ISO standard containers. The carrier straddles its load, picking it up and carrying it by connecting to the top lifting points using a container spreader. Some machines have the ability to stack containers up to four high.
Reach stackers can transport a container short distances very quickly and pile them in various rows depending on their access. Reach stackers have gained ground in container handling in most markets because of their flexibility and higher stacking and storage capacity when compared to forklifts .
Containers, also known as intermodal containers or ISO containers because the dimensions have been defined by ISO, are the main type of equipment used in intermodal transport, particularly when one of the modes of transportation is by ship. Containers are 8-foot (2.4 m) wide by 8-foot (2.4 m) or 9-foot-6-inch (2.90 m) high.
A modern container crane capable of lifting two 20-foot (6.1 m) long containers at once (end to end) under the telescopic spreader will generally have a rated lifting capacity of 65 tonnes. Some new cranes have a 120-tonne load capacity, enabling them to lift up to four 20-foot (6.1 m) or two 40-foot (12 m) containers.
Travelling by road. The sidelifter loads and unloads containers via a pair of hydraulic powered cranes mounted at each end of the vehicle chassis.The cranes are designed to lift containers from the ground, from other vehicles including rolling stock, from railway wagons and directly from stacks on docks or aboard container ships.
An intermodal container, often called a shipping container, or cargo container, (or simply “container”) is a large metal crate designed and built for intermodal freight transport, meaning these containers can be used across different modes of transport – such as from ships to trains to trucks – without unloading and reloading their ...
The primary uses are to securely stack containers, for locking them into place on a container ship, [1]: 4:18 semi-trailer or rail carriage, and for lifting and handling by specific container-handling equipment, like straddle carriers, reach stackers, container-handling forklifts, sidelifters, and various types of container cranes.
The spreader is placed between the container and the lifting machine. [1] The spreader used for containers has a locking mechanism at each corner that attaches to the four corners of the container. A spreader can be used on a container crane, a straddle carrier and with any other machinery to lift containers. Spreader operation can be manual ...
