Case gives us advice on how to lower operating and ownership costs of wheeled loaders.
Logging-on continues with the series of articles by Case that assist us to better manage our wheeled loaders. The first two aspects covered in the January 2 edition of Logging-on covered purchasing the correct size loader and knowing your engine. In this issue we examine:
- Matching axles to the operation: Using the wrong axle/tyre configuration to the application can cause increased wear to the tyres and can put excessive loads on the axles. Case offers three axle options designed for different applications. The limited-slip is suitable for most applications because it allows the machine to operate similarly to an open axle in non-demanding conditions. In normal operation, the differential equally supplies torque to each side of the axle, but if one wheel begins to turn faster than the other, the axle will automatically apply additional torque to the wheel with less traction and increase tractive effort to the opposite wheel. Differential lock is more suitable for demanding conditions. This axle can transmit 100 percent of the available torque to either wheel. The open axle is the simplest of all axle designs and is best suited for solid or hard-packed earth. Torque is delivered to both wheels equally.
- Automatic Bucket Controls: These allow the operator to set a position for the bucket, such as a “return to dig” to approach and hit the pile, allowing the operator to concentrate on manoeuvring the machine and practice safer operation while maintaining the machine’s hydraulic and mechanical effort for driving functions. The bucket will locate itself in exactly the right location that was set up by the operator.
- Attachment Maintenance: Worn cutting edges or bucket teeth will result in the loader working harder, consuming more fuel, spinning tyres and taking more time to complete the job. It can also cause unnecessary wear on the machine.
