Some of the tires in ports and terminals are very difficult to change, as they might be mounted under big cranes, as is the case with RTG-tires and straddle carrier tires. These are tires that are very expensive to change, so you want to ensure that they can handle all the different season without problems and that they are durable and will last. Since the ports and terminals are around the clock operations, there is no time for breakdowns that can slow you down.
The different machines will need very different tires and they will have very different properties to fulfill their tasks to ensure a high output and productivity during the work shift. The most visible tires are the tires on all the trailers and then the terminal tractor tires. The terminal tractors are used to move around the trailers around the ports and terminals before they are picked up or after they have been dropped off. This require that the container trailers have to be moved around in small spaces with good turning response and since the terminal tractors are low to ensure that they can manage in cramped spaces.
The tires on the trailers are normal truck tires, but specially designed for trailers, as truck tires are different for the steering and driving axle of the trucks. They are built for the long haul ensuring that the containers and the goods they contain will get to its destination without problems related to the tires. The main tire problems tend to be caused by low tire pressure. For trailers that are picked up it can be difficult to know if the tires are already in good condition and the same goes if the tires are approved for winter conditions, in case the transport enters countries where commercial winter tires are mandatory.
It can be worth checking the technical tire manual to ensure that you know the recommended tire pressure for all the tires that you will find within the port and terminal and also making sure that the correct tire is selected for the application where they will be used. You will need to ensure that the tires can handle the load, within the range where they can operate. All this information and more can be found in the manual.
Terminal tractors are the main machines that are using tires in the terminals for moving either goods or containers around the port area. You also have RTG-tireson the RTG cranes and the straddle carrier. They are having similar work environment, where they have very high loads, need for good steering response and easy of wheel turning under heavy loads, which is helped by its tread pattern. Tracks are also used, but the wheeled equipment has more flexibility to move things around and sorting and finding containers.
The terminal tractors tend to operate in small areas, where
they have to maneuver the containers with limited space and narrow margins. They
have to handle massive load capacity and they often have a low profile so that
you can manage better in vary tight spaces with limited vehicle height. To
handle the heavy loads the terminal tractor tires will have a
sturdy multi-layer structure. The terminal tractor will mainly move around the
containers that are already on the trailer, before it is picked up or after it
was dropped off. This allows for speedy reallocation of the containers around
the port area.
For the straddle carriers you will need to have sturdy tires
to make sure to avoid that the containers or the equipment start swinging,
which will slow down the work and can potentially cause accidents. Durability
is key, as it is not easy to change these tires, so wear resistance is of utter
importance. You can select slick or grooved, where the slick gives you better
driving comfort. The tires need to also have excellent grip on wet or icy
surfaces, so that they can operate even during winter conditions.
To achieve the high productivity needed and to ensure that
delays are avoided, which is needed due to the high volume of containers every
day, the tires will need to have special tread compound for terminal use, with
very low heat build up and low tyre wear, as tire problems would take time to
fix, so you will need long trouble free service life and low wear, so that they
can operate for a long time without unscheduled downtime. So when selecting
tires for terminal equipment, make sure to base the decision based on the
durability and long operating hours for higher productivity year in and year
When dealing with material handling and containers at harbors and container terminals, you will need different wheeled equipment to handle the containers in intermodal freight transport. Here the containers will arrive or depart by container ships and the containers will be unloaded or loaded at the terminals. From the ships the containers can be loaded onto train carts or then to truck trailers.
You will have RTG cranes that can handle the containers and also lift the containers into the trailers. You will need high load bearing and precise handling of RTG tires, so that you can handle the weight of the containers and also be able to easily ground and stack containers. The RTG cranes are huge, so you can imagine that changing tires is a task that one doesn’t want to undertake too often. This put a lot of pressure on selecting a tire that has very low tire wear. These wheels also turn very easily reducing wear while the wheels are turned at no or low speed. High quality RTG tires will be needed to ensure high operating hours and low wear.
You will also have a straddle carrier where you might want
to use slick tires to ensure the machines and the containers from swinging. You
will need very sturdy tires that can manage the high loads bearing capacity.
You will need top class wear resistance and great grip even in damp or winter
conditions. Driving properties are also
key when you drive around the container terminal stacking containers.
You then also have a terminal tractor that can move around
the semi-trailers around the yard while waiting for the trucks to pick up the
containers. These terminal tractor tires will need to
be able to move around heavy weigh containers and will need to have exceptional
load bearing capacity. Maneuverability and precise driving response even in
small and narrow spaces are key features that these tires need to have.
When dealing with containers, some of them are on a tight
delivery schedule, so that you will need to make sure that your tire selection
doesn’t slow down your operations due to tire failures or unscheduled downtime.
Once the containers are placed on the semi-trailer trucks, they still have a
long way to go before they reach their final destination; so don’t delay them
at the terminal.
Tractors can be used for multiple applications. In agricultural applications tractor is the main piece of equipment with different trailers and other towed equipment. The main agricultural tires used here are flotation tires, as you want to ensure that the compaction of the soil is minimal, so that yield will remain high.
You also have forest tractors that are used in the forest
industry, where the forest tires will need to ensure that you have some heavy
sturdy tires for demanding tractor use. These tend to be steel belt reinforced
for improved puncture resistance. Grip,
durability and ability to handle the most challenging forest terrain. This is
quite different than the properties needed for the agricultural tires.
Then you have the terminal tractors used for material
handling at container terminals. Terminal tractor tires need to
provide excellent steering response and ability to carry very heavy loads. The
terminal tractors need to be able to maneuver in narrow spaces, so predictable
handling is important for terminal tractor tires.
Within earthmoving and road maintenance you also have
tractors, you will have tractors, which road maintenance and earthmoving tires need to be
extremely puncture resistance through a steel fortified structure. You will
also need to rely on superior grip.
So the use defines the tires in a higher degree than the
equipment on which the tire is used. Tractors can be used in various different
applications and based on what conditions and what tasks are at hand will
determine what properties that you will need from your tires. It is thus
advisable that you check the technical tire manual to properly select the
adequate tires for the correct application where you intend to use your
equipment. Sometime you might need a more versatile tire, but you still need to
ensure that it can handle the loads that you will need to lift or transport.
The tires also need to be durable so that they don’t cur or crack under the
pressure or that the puncture due to sharp objects that are part of the working
Durability is of utter importance to ensure that you can
avoid any unscheduled downtime due to tire related problems that can add a lot
of cost and inefficiencies to your operations. Make sure to invest in tires
that can get the job done without problems.
Your cargo around the world is also heavily dependent on selecting proper tires. Most cargo nowadays is transported by sea with huge container ships arriving to massive ports that can handle large volumes. Everything is nowadays handles by big hubs, where the containers are unloaded and put on trucks for further delivery on land. There they will often be taken to a terminal, where the containers are then opened and the products can then be distributed in smaller shipments to their final destinations. The whole distribution chain is dependent on timely deliveries without delays.
with tires are involved in most of the transportation process, except the time
on sea. You will have trucks delivering the containers to the ports and these
will need to have good quality truck tires. At the ports you will have your
terminal tractors and RTG-cranes using RTG-tiresand terminal
Once at the final destination harbor, when the containers are transported on
land, you then need long haul tires for the long distance
transport. For these long distance transports low heat build-up is important
provide you with a low wear tire. Low rolling resistance gives you less heat
build-up and better fuel efficiency, so that you can deliver products more
degree of downtime also comes with better quality haul
that are built to last and sustain long distance driving. Unscheduled downtime
can be very costly, especially if you suffer substantial delays due to it. The
importance to find issues that can cause problems in the long run, is often
crucial to the efficiency of your operation. Try to get the drivers to report
any problem even small ones and make sure to check the tire pressure on a regular
basis, to avoid driving with too low tire pressure, which is the main reason
for tire failures.
rolling resistance provides the low fuel consumption, the lower wear translated
to less frequent replacements of tires, which are both adding to the economic
reasons of choosing high quality tires. Retreading of tires is another
important economic factor of choosing a high quality tire. Retreading can only
be done on high quality tires and if the carcass is in good condition.
Retreading can be done 1-2 times before the carcass has to be discarded.
Retreaded tires can add substantially savings to your tire budget.
A gantry is a bridge looking structure that can be used for mounting cranes, so that work can be done from the above certain items. A gantry crane varies in sizes, but tend to be very big. They are often used in shipping to lift containers and even to build or repair ships. It is often massive equipment made to carry massive loads.
cranes can be either on tracks or then you have rubber tired gantry (RTG)
cranes. Often you can find both alternatives in the same area. When you have RTG tires, theyhave to be able
to withstand enormous loads, but they are great as you can move containers
throughout the yard.
RTG tires have a tread that is designed for terminal use so that the heat build
up is low even at high loads. This will ensure that wear is low and you can
operate more hours before having any downtime. They are also easy to turn, as
turns are also done while stationary, so if the tires are not designed with
this in mind you might ruin your actuators or cause high tread wear.
