Sleipner E-series provides you with a solution for relocating your excavators in a safe, easy and efficient way. It prevents your undercarriage maintenance budget to overrun. And even more! Production, maintenance, daily mine planning, and long-term development, all benefit from Sleipner in use even as early as during the first few months from implementation.

Increased productivity

What's the typical working time distribution for an excavator like? Commonly excavators use 7-30% of working hours traveling on tracks. With Sleipner System, transporting an excavator can be sped up to a fraction of the time when compared to driving on tracks. The reduction of transport times can be up to 85% of the excavator’s traveling hours! Instead of three hours traveling on tracks, the excavator is transported in half an hour with Sleipner System. The remaining two and half hours the excavator is available to be used in profitable work.

That's a significant increase in the flexibility of excavator transport. It also means, that the loading can be planned more efficiently. The improved excavators’ utilization and availability rates can increase productivity between 12% and 20%. Using Sleipner units efficiently makes your excavators work effectively.

Maintenance savings

The maintenance cost of an excavator can be a major investment. The good news is, the costs can be significantly reduced by doubling or even tripling the lifespan of the undercarriage. Up to 1/3 of an excavator’s Life Cycle Cost (LCC) comes from undercarriage parts and maintenance. With Sleipner System, the only wear on the undercarriage is what's caused by the daily excavation operations. Depending on operating conditions and the excavator size, 10-18 % LCC savings are achievable.

Excavators need service and maintenance continuously. In a workshop, tools and spares are available in a safe working environment, making it the most suitable place for such operations. Safe and easy relocation of excavators enables their transportation for workshop maintenance, which is at least 20% faster than in the pit. This reduces excavator downtime and maintenance labor hours.

mine life cycle

The Sleipner transport system opens whole new possibilities for mine planning. You need fewer excavators because mobilization issues are resolved. Ore body can be reached quicker, because the mining sequence needs no compromises. The ability to reach the ore body much sooner brings huge savings in new mining projects. Completing the mine closure many months before planned means typically $1M+ savings per week.

Operational benefits

Wheels under excavators bring flexibility to operations. Excavators can be effortlessly moved and relocated whenever needed, even in the middle of a shift. For example, blasting breaks and fly-in fly-out roster changes are easily used for the maintenance actions in the workshop. If an excavator has a breakdown in an ore bottom of the pit, just borrow a replacement excavator from an overburdened area. The valuable ore digging continues as planned with minimal truck waiting times.

Safety

All operations are done mechanically with trained truck and excavator operators inside their cabins and in constant radio contact. Transport of an excavator can be interrupted at any time by lowering the excavator’s tracks, which are only about 40 cm off the ground. The maximum transportation speed is up to 15 km/h. An automatic parking brake mechanism keeps the Sleipner units in place when not in use.

User view

”It only takes a few minutes to load a couple of bucket loads of material into the truck’s bed, drive the excavator tracks onto the Sleipner unit, turn the upper carriage around and place the bucket on the truck’s bed. Then just lift the tracks up, give a horn signal to the truck driver and off you go to the next location. So easy, so simple!”

FAQ

Can I use the Sleipner System for multiple excavators?
+
-

You can safely use the same system for multiple excavators when the track width and pattern are identical and you do not exceed the operational weight.

What is the maximum speed?
+
-

Maximum allowed speed is 15 kmph in good conditions. During cornering, while going downhill, in narrow spots etc., the speed needs to be reduced according to conditions.

What if the truck operator drives too fast?
+
-

The excavator operator is always able to interrupt the transport first by lowering the tracks to touch the road, and then lowering them to the maximum by lifting the boom up.

How long do the Sleipner tires last?
+
-

Typically, Sleipner tires are running only a few hundred kilometers per year, not 24/7 like mining truck tires. Sleipner tires are trailing (idling), there are no steering forces thus wear and tear is minimal. Typical tire age is more than 10 years (or 5 years if daily UV radiation level is very high: 8-10).

Is on-site commissioning needed?
+
-

Yes, it is. The target of the commissioning is to assure that all system components are designed, installed, tested, operated, and maintained according to its design objectives or specifications. The supplier’s or dealer’s commissioning and/or training specialists will be in charge of the commissioning.

How long does it take to set up Sleipners under the excavator?
+
-

It only takes 2-3 minutes to load up once in place.

How about braking capacity on downhills?
+
-

In normal conditions, the truck retarding capacity is enough to carry an excavator safely downhill. Truck retarding capacity is always verified according to the actual road grades and truck manufacturer’s retarding capacity charts.

Can the Sleipner transport cause harm to the excavator boom, cylinders or slew ring?
+
-

The Sleipner System won't create any additional loads that could cause harm to the excavator’s steel structures, swing ring or other components. During transport, the excavator supports itself with the same hydraulic cylinders that are used for digging. All forces on the excavator are generated by the hydraulic system. The hydraulic system has a main pressure relief valve and every cylinder circuit has its own secondary pressure relief valves. These valves are set according to the excavator design parameters to protect it from overloading. During Sleipner transport, the cylinder pressure levels are below the excavator design parameters.

Can the excavator fall off the Sleipner System abruptly?
+
-

Absolutely not. The excavator cannot fall abruptly from Sleipner System. Excavator tracks are supported on the Sleipner System cradles which are only about 40 cm off the ground during transport. In case the tracks would happen to fall off from the cradles, the tracks would fall off slowly, touching the ground smoothly and the transport would be interrupted. This kind of “abrupt fall off” is not possible if the Sleipner System is used according to instructions and operation procedures.

How does the Sleipner system handle wet and slippery conditions?
+
-

The Sleipner E-series can be used in same weather conditions as normal mining trucks. The Sleipner System is widely used from icy artic sub-zero temperatures to tropical rainforest climates.

How about quality?
+
-

To guarantee safe and faultless products and operations, Sleipner manufacturing processes follow the Quality management system (ISO 9001:2008). Inspections and testing of each Sleipner unit is done and documented according to the Quality Management System.

Can the Sleipner System harm undercarriage track tensioners / brakes?
+
-

No. The forces during normal digging are much higher than during Sleipner transport.

Does the Sleipner System have brakes?
+
-

Every wheel is equipped with an automatic
parking brake keeping the axles in place when not used. The parking brake is
fully mechanical and it is a fail-safe system.

Can the Duratray rubber lined bed be used in the towing truck?
+
-

Yes. The Duratray supports Sleipner System.

What is the expected life of a Sleipner System?
+
-

This question hasn't got a definitive answer. The first system put to work in 1996 is still in use today!

What maintenance is involved with the Sleipner System?
+
-

The maintenance is broken down to weekly, monthly and yearly checks and actions. Basically, all critical and wearing parts require weekly checks, bush bearings monthly greasing, and hub oil a yearly change.

Do the OEMs of the Trucks and Excavators approve the Sleipner product?
+
-

Many CAT and Komatsu dealers around the world promote and sell the Sleipner transport system as a solution for their customers.

Is it safe to use?
+
-

Yes, it is safe to use. Operators need to follow trained safe working procedures. Detailed risk assessment is available. Sleipner System and operating procedures have been audited and approved in world-class mining companies like Vale, Rio Tinto and BHP.

Is the Sleipner system sustainable?
+
-

Yes, it is. The Sleipner transportation system is created to improve sustainability as a whole. Using the Sleipner transportation system decreases fuel consumption and emissions during transportation.
