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.
Excavating limestone typically involves using heavy machinery such as excavators, bulldozers, and rock drills. The process begins with site preparation, followed by the use of jackhammers or hydraulic breakers to fracture the rock. For larger operations, quarrying equipment like wire saws or diamond wire cutters can efficiently remove blocks of limestone. Safety gear and proper planning are essential to ensure a safe and effective excavation process.
