Container Spreader
A container spreader is a tool used for lifting containers and unitized cargo. The spreader is placed between the container and the lifting machine. 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, semiautomatic or fully automatic.

Container Crane And Spreader
A container is any receptacle or enclosure for holding a product used in storage, packaging, and transportation, including shipping. Things kept inside of a container are protected on several sides by being inside of its structure. The term is most frequently applied to devices made from materials that are durable and are often partly or completely rigid. A container can also be considered as a basic tool, consisting of any device creating a partially or fully enclosed space that can be used to contain, store, and transport objects or materials. History Humans have used containers for at least 100,000 years, and possibly for millions of years.Clive Gamble, ''Origins and Revolutions: Human Identity in Earliest Prehistory'' (2007), p. 204. The first containers were probably invented for storing food, allowing early humans to preserve more of their food for a longer time, to carry it more easily, and also to protect it from other animals. The development of food storage cont ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Twistlock
A twistlock or twist lock, together with matching corner castings, as defined in norms including ISO 1161:1984, form a standardized (rotating) connector system, for connecting and securing intermodal, and predominantly ISO-standard international shipping containers. The primary uses are to securely ''stack'' containers, for locking them into place on a container ship, 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. Twist-locks also have to be used when stacking containers shorter than together with 40foot and longer containers. Containers shorter than 40feet containers must be joined together horizontally with twist-locks, to form a rigid combined whole 40feet in length, to make them stackable and be able to support and be supported by an ISO standard 40- or 45foot container stacked underneath ...

Container Crane
A container crane (also container handling gantry crane or ship-to-shore crane) is a type of large dock (maritime), dockside gantry crane found at container terminals for loading and unloading intermodal containers from container ships. Container cranes consist of a supporting framework that can traverse the length of a quay or yard on a rail track. Instead of a hook, they are equipped with a specialized handling tool called a spreader (container), spreader. The spreader can be lowered on top of a container and locks onto the container's four locking points ("corner castings") using a twistlock mechanism. Cranes normally transport a single container at once, but some newer cranes have the capability to pick up two to four 20-foot containers at once. History Cranes were used in harbors starting in the Middle Ages (see Crane (machine)#Harbour usage, crane: harbor usage and list of historical harbour cranes). Modern inter-modal containerization emerged in the mid-1950s from transp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Straddle Carrier
A straddle carrier or straddle truck is a freight-carrying vehicle that carries its load underneath by "straddling" it, rather than carrying it on top like a conventional truck. The advantage of the straddle carrier is its ability to load and unload without the assistance of cranes or forklifts. The lifting apparatus under the carrier is operated by the driver without any outside assistance and without leaving the driver's seat. Lumber carriers The straddle carrier was invented by H. B. Ross in 1913 as a road-going vehicle that could easily transport lumber around mills and yards. Lumber was stacked on special pallets known as carrier blocks; the carrier would then straddle the stack, grasp and lift the carrier block, and drive off with the load. Because a straddle carrier is open at both front and rear, it can transport lumber much longer than the carrier itself, over in length. The Ross Carrier Company (now Northwest Caster & Equipment ) was founded in Seattle to manufactur ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intermodal Container
An intermodal container, often called a shipping container, or a freight container, (or simply "container") is a large metal crate designed and built for intermodal freight transport, meaning these containers can be used across different Mode of transport, modes of transport – such as from container ship, ships to Rail transport, trains to Semi-trailer truck, trucks – without unloading and reloading their cargo. Intermodal containers are primarily used to store and transport materials and products efficiently and securely in the global containerization, containerized intermodal freight transport system, but smaller numbers are in regional use as well. It is like a boxcar that does not have wheels. Based on size alone, up to 95% of intermodal containers comply with ISO standards, and can officially be called ISO containers. These containers are known by many names: cargo container, sea container, ocean container, container van or sea van, sea can or C can, or MILVAN, or SEAVA ...

Spreader Beam
The lifting beam (also known as traverse, spreader beam) is a steel beam that is attached to the hook of the crane in order to spread the Sling (rigging), slings from one end of an elongated load (like a wall panel) to another. The bottom of the beam has multiple connection points for hanging the load. The lifting beams are used in multiple cases: * lifting an asymmetrical load. Without a beam, it might be hard to strap the load so that its center of gravity is exactly below the hook; * handling a long load with a single-hook crane. Sufficient spread between the slings prevents the load from slipping out; * increase the headroom: slings cannot be stretched close to the horizontal direction, so attaching them directly to the hook requires a minimum distance from the hook to the load. When the lifting beam is used, the slings can be shorter, providing more vertical clearance during lifting; * if the attachments of the load are on its vertical sides, the slings have to go over the edg ...
