Hydraulic Drive Motors and Mining

Mining Machines

There are many, many different machines that are used in connection with mining.  Most of the machines, from small loaders to gigantic mining trucks, use hydraulic motors.  The focus of this blog post is the use of hydraulic motors in the mining industry, with an overview of some of the classfications for mining equipment.




Shop Talk Blog continues to provide strategic informational and educational articles to keep you ahead of the curve on heavy equipment for your industry.  Here are other key posts on Hydraulic Motors to keep you well-informed:


Mining Trucks

While some of these trucks use an electrical wheel drive, others use hydraulic drive motors with an integrated gearbox, or what is often termed a final drive motor



Mining Excavators

While front shovels have a bucket that digs forward and away from the machine, excavators have buckets that dig back and toward the machines. Both excavators and front shovels are tracked machines requiring hydraulic track drives.


Wheel Loaders

The typical wheel loader uses hydraulic drive motors to power the wheels, although in the future we may see electric drive motors.



Bucket Wheel Excavator

These are some of the largest machines in the world and are impressive feats of engineering. Bucket wheel excavators are primarily used in cross-pit mining and use a fascinating system of buckets (hence the name), chutes, and conveyor belts. These very large machines are track-driven, and use a hydraulic track drive or final drive.



Blasthole Drills

The objective of a blasthole drill is to drill a hole into which a electric charge is placed. Most, if not all, blasthole drill rigs are tracked machines. They use hydraulic track drive motors with high torque output to run the tracks and thus move the machines.

Continuous Miners

Hydraulic motors are used to drive the tracks. These track drive motors typically have a gear box with a very large reduction ratio to achieve maximum torque.



Crawler Tractors

Many people recognize the crawler tractor when it is referred to by the name bulldozer or dozer. These machines have a blade attached to the front (if it is a loader attachments, it would be referred to as a crawler loader). Because they are tracked machines, the have track drive motors with reducing gearboxes to generate tremendous amounts of torque.



Other Pieces of Equipment

Other common sights in mining would include the crawler crane (a tracked crane, hence its name) and the crawler loader -- both require hydraulic track drive motors. Some roof bolters are tracked and also use track drives. Compactors, motor graders, and motor scrapers may also be used in mining applications and typically have hydraulic drive motors.


Eaton Hydraulic Motors and Mining

When it comes to final drives and hydraulic motors for mining applications, one of the key characteristics is efficiency, both mechanical efficiency and volumetric efficiency. Also key for many mining applications is a high starting torque, high torque density, and high power density.  For track drive motors in mining, the Eaton JMV series of hydraulic motors is an excellent choice because of its efficiency, high starting torque, durability, and compatibility with most installations.
