in a car with an automatic transmission that is in a drive gear (D,1,2,3,OD, etc) the engine is always connected to the transmission, unlike a manual-shift transmission where the clutch disconnects the two. the car's engine at idle speed still provides some power, so the car will always try to move forward. your foot on the brake keeps it from moving forward, but doesnt cause the car to stall. this is possible because you have a torque converter, which allows for energy to be redirected when the brakes keep the car from moving. for more info read up on how a torque converter works at a site like howstuffworks.com
Possibly, if you are being aggressive with the excavator, setting the parking brake would take tension off the transmission though.
