because it helps lift it with the pulley doing all the work.
Zero swing excavators are excavators that the rear/counterweight part of the machine do not extend further than the tracks. So the operator doesn't have to worry about allowing a swing radius for the rear.
Most excavators now use hydraulic controls for almost everything except possibly forward and reverse track motion
What do you mean by mechanism? Hydraulic tube???? Even small excavators have many pivots - something like 30 or so, excluding any in the tracks, if it has tracks. All are simple hinge mechanisms consisting of two or more bushed holes and a precision-ground pin.
Hydraulic drive systems like gear pumps, rotary vane pumps, screw pumps, bent axis pumps etc. One real life example of hydraulic pumps is the brake master cylinder in a car. You also see hydraulic pumps in excavators.

Crawler excavators doesn't. They have a hydraulick motor.
