How Does The Excavator Machinery
Technology Develop
Excavators are large development equipment made up of a
growth, keep, pail and cab on a spinning system (known as the
"house"). The home rests on top of an undercarriage with paths or
tires.
A cable-operated excavator uses winches and metal rules to
achieve the motions. They are a natural development from the
vapor spades and often called power spades.
All activity and features of a gas excavator are achieved through
the use of gas liquid, with gas tubes and gas engines. Due to the
straight line actuation of gas tubes, their method of function is
essentially different from cable-operated excavators.
Every year, the excavator machinery for sale is largely demanded
by many industrial walks, especially the construction walk.
Initially, the excavator is manual, it has been 136 years from the
present invention to 2013, during which the gradual development
process has experienced from the steam-driven rotary excavator
bucket to the electric drive and the internal combustion engine
driven rotary excavator, hydraulic integration of the full
application automatic hydraulic excavator.

The first hydraulic excavator was successfully invented by the
French Poclain factory. As for the hydraulic technology, an
overhead excavator emerged in the 1940s with a tractor
equipped with hydraulic backhoe. In 1951,the first hydraulic
backhoe excavator was launched by Poclain ( Poclain ) factory
in France, resulting in a new space created in the field of
excavator technology development.
In the early 1950s and mid the humans have developed a towed full
rotating hydraulic excavators and crawler hydraulic excavator.
Initial tried hydraulic excavator was made by the use of the
hydraulic technology of aircraft and machine tools, hydraulic
components of which were lacked for a variety of working
conditions for excavator, and the manufacturing quality is not
stable enough, parts are neither complete.
From the 1960s on, the hydraulic excavator boomed into the
promotion and development stage, the excavator manufacturers
and varieties of countries increased rapidly with the production
soared. Among the years from 1968 to 1970, the production of
hydraulic excavator accounted for 83% of total production, and
was close to 100%.
