Container handling equipments include many,reach stackers, Forklift trucks,empty handlers,

straddle carriers,tractors,, quay cranes, yard cranes, ASCs, shuttle and straddle carriers,Rubber

Tire Gantry Cranes,ship loader, jib portal crane etc., Yufei could make all of them theoretically,but

we did make all due to we pay much more attention on heavy duty equipment only.

1.Ship to Shore Container Cranes(STS)

(Yufei-made 400Ton Shop-to-shore containers crane in Haifong Port Vietnam since Aug.2008)

Also called 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,

and a moving platform called a "spreader". The spreader can be lowered down on top of a

container and locks onto the container's four locking points ("cornercastings"), using a twistlock

mechanism. Cranes normally transport a single container at once, however some newer cranes

have the capability to pick up two to four 20-foot containers at once,which could be made by us as

long as customers ask.

The crane is driven by an operator that sits in a cabin suspended from the trolley. The trolley runs

along rails that are located on top or sides of the boom and girder. The operator runs the trolley

over the ship to lift the cargo which generally are containers. Once the spreader locks onto the

container, the container is lifted and moved over the dock and placed on a truck chassis (trailer) to

then be taken to the storage yard. The crane will also lift containers from chassis on the dock to

load them onto the ship.

Operation

The crane is driven by an operator that sits in a cabin suspended from the trolley. The trolley runs

along rails that are located on top or sides of the boom and girder. The operator runs the trolley

over the ship to lift the cargo which generally are containers. Once the spreader locks onto the

container, the container is lifted and moved over the dock and placed on a truck chassis (trailer) to

then be taken to the storage yard. The crane will also lift containers from chassis on the dock to

load them onto the ship.

Straddle carriers, sidelifts, reach stackers, or container lorries then manoeuvre underneath the

crane base, and collect the containers—rapidly moving the containers away from the dock and to a

storage yard. Flatcars or well cars may also be loaded directly underneath the crane base.

Power

A crane can be powered by two types of power supply; by a diesel-engine driven generator located

on top of the crane or by electric power from the dock. The most common is by electric power

from the dock (also known as shore power). The voltage required may range from 4,000 up to

13,200 volts.

History

Cranes were used in harbors starting in the Middle Ages – see crane: harbor usage and list of

historical harbour cranes. Modern intermodal containerization emerged in the mid-1950s,

emerging from transport strategies developed in the Second World War and the Korean War, and

specialized cranes parallelled developments in containerization.

In popular culture, container cranes are occasionally called AT-AT cranes due to their resemblance

to AT-AT walkers in George Lucas's Star Wars films, although Lucas denies their inspiration.

2. High profile portal container cranes

(5Yufei-made 50T portal container cranes in Congqing Huangqi Port since 2009)

This type has the similar function to the STS one, where the boom is hinged at the waterside

of the crane structure and lifted in the air to clear the ships for navigation.

3. Rail Mounted Container Gantry Crane(RMG)

(A Yufei-made 45 ton RMG in a newly built container yard in China)

Rail Mounted Gantry Crane are commonly found in factory applications such as steel yards,

paper mills or locomotive repair shops, also widely used in container yards, which has rails

installed on the ground and gantry-style legs to support the crane. Capacities range from 2 to 200

tons, and sometimes even greater capacities. Most are electrically powered and painted safety

yellow.

4. Rubber Tyred Container Gantry Crane(RTG)

(A Yufei-made 40 ton RTG container crane in Yangon Port,Myanma)

A rubber tyred gantry crane (RTG crane) (also transtainer) is a mobile gantry crane used for

stacking intermodal containers within the stacking areas of a container terminal. RTGs are used at

container terminals and container storage yards to straddle multiple lanes of rail/road and

container storage, or when maximum storage density in the container stack is desired

A normal container crane runs on steel rails, instead of rubber-tyres. The side-view appearance of

a RTG and a straddle carrier are fairly similar, but the top of a RTG also features a movable crane.

Above are the container handling cranes we made once, we are happy and willing to receive

inquiry on other container cranes from you.
