Hydraulic systems are extremely important to the operation of heavy equipment.
Hydraulic principles are used when designing hydraulic implement systems, steering
systems, brake systems, power assisted steering, power train systems and automatic
transmissions. An understanding of the basic hydraulic principles must be
accomplished before continuing into machine systems.
Hydraulics play a major role in mining, construction, agricultural and materials
Hydraulics are used to operate implements to lift, push and move materials. It wasn’t
until the 1950s that hydraulics were widely used on earthmoving equipment. Since
then, this form of power has become standard to the operation of machinery.
In hydraulic systems, forces that are applied by the liquid are transmitted to a
mechanical mechanism. To understand how hydraulic systems operate, it is necessary
to understand the principles of hydraulics. Hydraulics is the study of liquids in motion
and pressure in pipes and cylinders.
