Be used to promote and carry the machine of load, particularly freight container

Technical field

The present invention relates to a kind of machine that is used to promote and carry load, particularly freight container.

Background technology

Known, container loading discharged primary activity to ship and from the ship is carried out at the harbour dock.

These docks are equipped with bigger dock crane, and this dock crane is end wise and advance abreast with ship in orbit.

Two handling systems or the working cycle that are used to unload and load ship are called freight container carrying activity.

Particularly, for the unloading or the loading operation of ship, the carrying of freight container only just begins after berthing of ship finished.

In case berth, the dock crane motion is in place, so that prepare actual load or unloading.These hoisting cranes are positioned on the dock in the front of ship, and their crane arm rises.

When dock crane side by side the time, crane arm reduces and is positioned at above the cargo hold of ship, so that unload, thus beginning conveying container (unloading and load).

Hoisting crane is equipped with they self suspender separately.Some nearest years have been used so-called " two lifting " suspender pattern.It can every circulation carry one 40 forty equivalent unit 40 or two 20 forty equivalent unit 40s, and can per hour unload nearly 35/40 40 forty equivalent unit 40 or 60/70 20 forty equivalent unit 40.

In case dock crane begins to carry out their working cycle, the harbour just comes into play, and is used for the whole consecutive sorts of freight container and the activity of distribution, and is to stacking the field, perhaps opposite from the dock of going home.

The unloading of freight container is carried out like this:

Directly delivered on the trailer by dock crane and (pulled by primary mover or tractor truck), be used to make them to be sent to and store stack, store at this and stack, they arrange under the effect of the stacking field hoisting crane in stacking again, so that further stacking;

Perhaps directly deliver on the ground, when the harbour is equipped with from loading and unload certainly equipment for example when fork truck, front swing-machine (reach-stacker) or straddle carrier, they can be sent to discharged freight container stacks, and they carry out stacking again in this stackings field.By this discharging method, dock crane can improve their capacity rating.This is because freight container is directly arranged on the ground, rather than it is arranged on the trailer, and they can be worked more fast and reliably.

After freight container arrive to be stacked, they by a series of stacking field hoisting cranes of so-called RTG (rubber tire gauntry crane) or RMG (track installation gauntry crane) type one be stacked in another and push up.

The great number of ship in the harbour stops cost (particularly for big ship) every day in short-term and also must consider.

Therefore, can obtain increasing transportation volume at the harbour that shorter time discharges ship and attract new shipping company.

Therefore, for the harbour, the most important thing is to improve their capacity ratings in whole stages of freight container carrying, like this, the harbour operating personal can discharge ship as quickly as possible.

In order to guarantee the turn round time faster; need to make from dock to a Large Ship Dock hoisting crane of stacking, stack a hoisting crane and other freight container traffic device can be in the shortest usable time loading and unloading freight container as much as possible, thereby avoid causing any shutdown and the operation of the loss of time.

But,, need make all machines all manufacture enough big intensity, and can send overall bigger weight to ground, and can not make that the overall dimension of machine self excessively increases in order to realize all these purposes.

At this on the one hand, must be pointed out that the conventional machines that is installed in usually on the wheel system can not fully satisfy aforementioned basic need.
