There's little in the way of a wheel loader that hasn't been affected by the introduction of electronics.
"Electronics play an important role in the overall value of our machines and affect all aspects of machine operations," says Alan Pumklin, Caterpillar Inc. "They provide tremendous improvements in the areas of safety, operator comfort, productivity, reliability and dependability."
What started as basic advancements with Tier II engines has progressed to greater precision and control in units equipped with Tier III power plants. Further advancements are likely as Tier IV engines are introduced.
"As manufacturers move toward more electronically controlled machines, operation becomes simplified, owning and operating costs may be reduced and hitting production targets becomes easier and more consistent," notes Nick Tullo, Volvo Construction Equipment.
Machine performance
Electronics have affected loaders in three key areas:
1. They have enhanced machine performance by controlling the engine and transmission for benefits such as reduced emissions and smoother shifting.
