When working both in underground mines and similarly in tunneling, you have a few things in common. You are working in confined spaces, drilling through rock and having sharp rocks and debris all around you. The confined space, mean that some of the equipment will have to be adapted to the smaller space. Due to the harsh conditions, the equipment used has to be extremely durable and resistant to impacts. The tires have to be able to also handle these very extreme conditions where it is a combination of very heavy loads and the sharp rocks and debris. This in combination with the fact that any tire problems is more difficult to handle deep down in a mine.
It is essential to avoid any problems makes it very important to ensure that the mining tires that are chosen for the various machines used becomes very important. The costs associated with problems leads to the fact that price of the tires will be less significant than the performance. These tires have to deliver long and trouble free service lift. The tires will need to have cut and crack resistant rubber compound and enough steel reinforcement to prevent any punctures. The loader tires, will need to have very good grip to be able to load the heavy debris into the dump truck, without slipping and then of course very durable. The excavator tires or drill rig tires also will need to have good stability and grip, so that the digging won’t be negatively impacted.
Productivity matters to ensure that the projects can finish
on time and not be delayed. Tunneling projects have to meet specific timelines
to ensure that the overall projects can be completed on time and for the
contracting companies not to be penalized. For the mining projects it is more
about general productivity, as delays will cause less profit and more costs, so
both factors are affecting you negatively. So this puts a lot of pressure on
you actually selecting the correct tires from the start. Tires that are built
to last and that will get the job done without any problems or delays. By using
the technical manual, you can get a good overview of the full assortment of
tires that is available for mining applications, so that you can select the
When using earthmoving equipment at construction sites, it is important that you have premium tires on your equipment that can handle sharp debris that will be lying around the construction site. This can easily damage your tires on your wheel loaders, dump trucks and excavators. On a site you will have a lot of metal debris and sharp rocks that easily can damage tires, especially if you don’t have very durable tires that are properly reinforced.
At later stages on construction sites, you might not do any
more excavation, but you will still need a loader and a dump truck to remove
some of the heavy garbage and debris. While working you want to make sure that
you have an aggressive tread pattern for superior grip while you might even
need a radial all-steel construction for avoiding cuts and cracks. You need to
make sure that the tires can handle the heavy loads, not crack under the
pressure and not rupture or puncture due to the surroundings.
When looking for loader tires and excavator tires, you will have quite similar specs, even for the dump truck tires; will have some similar properties when they are used on site. Tires for dump truck will need to have on and off road tires, with properties, where they have to be able to deliver according to the circumstances present while on site and then have the properties for on road driving. On road driving requires that the tires will have low rolling resistance for low heat build up and low tire wear. Driving comfort is also important in the way that the drive needs to be smooth.
By ensuring that your equipment have proper tires you can
often ensure that you will be able to avoid delays due to tire problems or due
to not being able to delivery due to delays caused by not having prober grip.
There might even be instances where you will need to have winter tires, so that
work can continue regardless of weather conditions. You don’t want to have
massive delays just because the tires are not capable to handle winter weather.
This can end up being an expensive situation, where you just have wait for
better weather. If your area might have snow, you should be prepared for it.
One might wonder what is meant by Nordic conditions and it basically means that you have 4 distinct seasons with the winter season being very harsh with a lot of snow and ice combined with some occasional very low temperatures. This means that the equipment that need to do construction and road maintenance work will need to work all year round and have to tackle the harsh winter weather. The tires will need to provide you with sufficient grip even during harsh winter weather. If they work in the Nordics, they will basically work anywhere around the world.
The main equipment used for these tasks are excavators,
wheel loader and dump trucks in addition backhoe loaders, tractors and road
graders belong to the equipment frequently used. Road graders play a crucial
role in ensuring that the road will be perfectly level before they apply the
top levels. So not only do these tires need to provide the grip during the warm
summers, but also when working in snowy and icy conditions, when the work has
to be done regardless of weather conditions. That is when you are happy that
you can turn to Nokian Heavy Tyres range of tires. They have been used for
decades in these applications and have constantly improved to ensure higher
productivity as also the machines have improved. The machines tend to gain in
power and weight and the tires need to respond for the higher loads.
When trying to find the tires for an excavator you can use
the Nokian Tyres technical tire manual to see the
full range of excavator tires. The new Nokian
Ground Kare is a new tire for excavators and backhoe loaders for versatile
contracting work. They are built to absorb shocks and swings to make the
excavator very stable. They have bigger blocks, which makes road driving very
comfortable as you travel between work sites. So if you need versatile
excavator or backhoe tires, this is a new
exciting addition that might suit your needs. They even have a semi-slick
version that is designed for railway work. This is what comes from working
closely with the equipment manufacturers and its customers, developing
products, which solves a need in the market place. Now you have a superior tire
for that specific application.
As you can imagine that tires for mining and tunneling work in harsh conditions, it doesn’t get much tougher than this. Sharp rocks that constantly cut and bruise your mining tires, as you have to work with extreme loads, provide these harsh conditions. The only benefit might be that working underground you have less of a weather impact. However being underground then means that you have limited amount of space, so you want to avoid any type of unforeseen problems with your equipment or your tires, as this can cause a lot of problems and costs. A tire failure can cause both delays and costs to a project in addition that it might be a hazard, as these tires work under very high pressures and they do carry very heavy loads.
The tires will thus have to be extremely durable and have a
cut and crack resistant tread compound that will provide you with long service
life with limited unscheduled maintenance downtime, so that you can maximize
productivity. With the limited room to maneuver in the tunnels you will need to
have very steady and precise handling. The main vehicles used that you will
need tires for are your drill rigs that will drill into the hard rocks. Then
you have your underground excavator that can continue digging. They are then
paired with a special low height underground mine loader, that can lift very
heavy loads and then dump it into a dump truck which tend to be articulated for
better movability and load bearing properties. The dump truck can then
transport the rock and debris from the underground via the access roads.
The different equipment will have different tires that all
will have slightly different properties in addition to being able to withstand
the tough conditions that prevail underground and the heavy loads. The loader tires have to have excellent grip so that it can easily
fill the bucket without tire slippage. Your excavator tires will need to be
very stable so that it can dig up rocks without the excavator rocking back and
forth. The dump truck tires will need to have good driving properties as it
will leave the mine or tunnel through the access roads at higher speeds, so it
needs to have both good on and off road properties. For

When you are working with heavy equipment such as wheel loaders and excavators, you might need to assess if you need to equip them with tires that are more suitable for winter conditions. Since with these type of equipment you are reliant on good grip and stability to perform the tasks that are required. There are heavy loads combined with ability to get the job done regardless of weather or surface.
Each one of these different machines has different
requirements when it comes to the tires, depending on their main tasks that
they perform. For the excavator you need to have very good stability while
digging and good grip so that you can remain in one place. For a loader, you
will need to have great traction combined with stability. They both have to be
able to cope with very high loads and have to be very puncture resistant to be
able to work in those environments without risking a flat tire.
Without the proper tires to do the job, you risk wasting a
lot of time by tire slippage and each task taking longer time to perform. If
you then add tire related problems, your work projects can quickly become
unprofitable. You need excavator tires that will not let
you down, that will provide sufficient stability and grip while you are
digging. Then you need wheel loader tires that will
provide you with sufficient grip so that you can scoop up all the material and
deliver it to a dump truck or other location. If you don’t have sufficient grip
then your tires will slip as you try to fill the bucket. So you will spend more
time on doing the same job. This is why tire selection is so important. The
cost of a wrong selection can far exceed the cost of the tires, so take your
time to do the right decision.
It might be useful to use the technical tire manual when you try to find the right tires for
the different machines. It has all the dimensions of the tires as well as what tire
pressure should be used and the maximum loads for the tires. It is a very
comprehensive manual that has a lot of information regarding the full range of
tires, so that you can make the best tire decision.
A backhoe loader is a multi-functional machine using much different equipment. The backhoe loader weight has increased over time to ensure that it can perform the wide range of tasks in a safe and efficient way. Nokian Tyres is now targeting this segment of backhoe loaders with two of its specially designed tires for backhoe loaders. That can manage the very high loads that the new generation of backhoe loaders need to face while using very heavy auxiliary equipment.
The new tire family for backhoe loaders is Nokian Ground Kare, where they have now launched two new tires; one is targeting railroad use where half the tire is slick to create a semi-slick tire and the other is targeting meadow use with soft impact on grass. The tread pattern in these backhoe tires are specially designed for low surface pressure with big central blocks also enables smooth driving on roads between sites. They are very cut and crack resistant due to steel belt and offer excellent grip due to the special edges that give good traction, while still offering good stability while you are digging. The edges are also great for self-cleaning which reduces the wear on the tire, especially when driving on-road.
As a summary
if you are doing railroad work and need a semi-slick tire to improve the
efficiency, the Nokian Ground Kare is probably a very good tire for you. It
offers all the benefits that you want out of a high caliber tire, that can
delivery high service output and low downtime due to tire problems. The low
impact on grass and soil also makes it perfect where you will need low surface
pressure combined with excellent grip and stability while working. IN addition
you get excellent properties both on and off road, so that you can easily
travel between sites without excessive wear due to heat buildup and the driving
comfort when being on the road is high.
can use the same tires if the use case as what the Nokian Ground Kare has been
designed for. Use the technical
tire manual to help
you identify which tire is most suitable for your equipment. Today excavator
tires have become
very specialized so there will be tires for most use cases if the demand is
high enough for the tire companies to develop a specific tire for it.
When you deal with underground mines, you have by default tricky working conditions. Underground hard rock mining are created are created by digging holes and excavating to find minerals or metals. In practice it is very similar to building tunnels in part similar equipment is used. It is all about breaking ground and removing it, so you excavate and dump it in a dump truck for removal. For tunneling the aim is just the hole from one side to another, while the mines you just want to rich mineral rich compounds.
The working conditions tend to be similar between
tunneling and mining, as you have confined spaces; you carry heavy loads while
excavating and getting rid of broken rocks via dump trucks. The conditions for
the equipment is harsh, with very sharp rocks, so the tires will sustain
constant abuse while working. So from a
durability point of view, you will need the best possible tires. Maneuverability,
so that you can move in tight spaces becomes critical, good grip and then to
ensure that you have a good cut and crack resistant rubber compound.
When it comes to mining
tires, you can always create good puncture resistance
through using chains or deep groves. Groove indicators make it easy to read how
much depth remains. Avoiding unscheduled downtime due to tire failures or
equipment problems is something that you really want to avoid working below
ground. The limited space and the dependency of other vehicles make these
breakdowns expensive and often time consuming. You want trouble free service life from your
tires, to ensure a smooth operation. Good grip will ensure that you can work
safer and that work conditions will not slow you down. You also need to be able to maneuver with
good precision within the limited space and have good stability while you work.
tires and the mine loader tires
should be checked at the end of each day. The best is to wash them and see if
there are any visual damages. It is always easier to do a scheduled maintenance
that to do an unscheduled repair. Proper tyres will have low wear and low
rolling resistance, so that your fuel consumption will be low while working. Check
that you are operating with the correct tire pressure based on your load for
You will see both wheeled and tracked excavators around, there are some advantages and disadvantages between them, and the wheeled ones are more flexible. You might lose some depth when you dig as the wheels gives added height to the excavator, so the boom is higher above the ground, however the stabilizers that the wheeled excavators have give the added stability to the machine so that you actually have more power for lifting and digging power.
The main advantage of
the wheeled excavators is in that they are more flexible when it comes to
moving around. Both the better ability to maneuver as well as the higher speed,
can speed up job projects when you have a wheeled excavator. Wheeled excavators
don’t need to be transported between jobs if the distances are not that great, as
you can drive them on normal roads. Not having to use a trailer to transport
the excavator between jobs can save you costs and time.
With a wheeled excavator
you also have the flexibility to change tires depending on the working surface
or area. This will definitely give you an extra degree of freedom and ability
to always have the best grip. There are a lot of different excavator tires
to choose from. Check the technical
tire manual to assess which earthmoving
tires are the best for your excavator.
Excavators are mainly
used in earthmoving and road maintenance jobs, so you tend to see them all over
the place. Combining the best equipment with the best tires, tend to save you
money in the long run in terms of running and maintenance costs and your
productivity should increase. When you have a wheeled excavator it is important
to check the tires at the end of each workday, to see that the tires are ok and
that they are free from any cuts or cracks. You always want to detect problems
at an early stage, preferably during the scheduled maintenance. Having
unscheduled downtime due to equipment or tire failure can be vey costly and
dangerous. The tires have very high pressures and accidents can happen if you
don’t follow the safety guidelines. Breakdowns always cause delays and can
jeopardize your timelines to get the job done. If you have a lot of breakdowns,
you need to schedule more maintenance opportunities.
Whatever type of heavy equipment you have, you will need to have heavy tires and preferably a good set of high-quality tires. As there are both wheeled loaders and tracked loaders and they both have their advantages and disadvantages. Only the wheeled loaders need tires, as the tracked ones have tracks for moving.
you don’t already have a loader, you will have to decide which one to buy. The
decision depends a lot of what tasks you want the loader to perform. For the
wheeled loader, the middle pivots so they can turn better than a tracked one.
Tracked ones requires one side to rotate backwards and the other forward, thus
wheeled are better and quicker when it comes to working in limited space areas.
Wheels are also able to move faster and can drive at higher speeds.
you drive any type of loader, make sure to wear seat belts and check that there
are no warning signals when you start it. They are not very difficult to drive,
but you do need some training using the steering wheel and the tool control. For the bigger loaders you tend to have a
joystick instead of a steering wheel. It tends to be that left hand is used for
driving and right to control the tools. When you turn the steering wheel the
cab actually swings, so the tires don’t actually turn, the whole machine
sure that your bucket is above the ground when you drive, but below the
eyesight to ensure you have good visibility. It is recommended that the bucket
is closed when you drive.
choosing excavator tires,
make sure that you select tires that will be able to do the job they are intended
to do, you might want to check the technical tire manual to ensure that your
tire option is the correct one. Make sure that you take all the terrain and
weather options into consideration when you make your tire selection. You don’t
want to end up not being able to perform jobs due to bad weather.
First of all, a backhoe loader is a heavy equipment and belongs to the series of excavators. Due to the fact that it is heavy machinery it requires heavy tires and there are special excavator tires. Without proper tires you might end up getting stuck or overloading the tires that can cause the tires to completely rupture. Any tire related problems can cause a lot of extra costs and lost revenues and should be avoided. It can also cause accidents to happen, so high quality tires that can handle high loads and is key. To ensure that you have full mobility in any weather or conditions, you need to ensure that your tires can handle this.
it comes to having tires instead of tracks when you are digging can cause the
backhoe loader to lose its balance due to the rocking. Solid tires that can
provide stability, but might not provide enough support, so often there is a
hydraulic stabilizers at the back and also lowering the bucket will provide
further stability to prevent the backhoe loader to actually tilt. Needless to
say if the backhoe loader actually tilts there can be serious consequences,
injuries and costly damages. It might not be fully prevented by proper tires
but definitely good tires can help prevent it.
improve the mobility, the tires need to be able to handle multiple different
surfaces and terrains. If the equipment also needs to perform in all weathers,
you need to make sure that the tires also can handle snow and ice. A tire that
is not designed for winter conditions, will get too hard to comply with the
surfaces and give the required traction to perform the work. Backhoe
loaders can in most countries only legally drive on public roads if
they are actually doing road construction work. If you intend to drive between
work sites, it is very important to check the local regulations to fully
understand the situation in your area. It might be that you have to get your
equipment transported between work sites. If you can drive it, you need to take
that into considerations when selecting the tires.
is always good to check the technical tire manual to ensure that you have
selected the correct tires for the intended load and that you have the correct
