How Hydraulic Machines Work


Another common piece of equipment at any construction site is the skid/loader (also known generically as a "Bobcat" because that was the name given by the manufacturer that first produced them):

Skid/loaders have three pairs of pistons:

  • The first pair raises and lowers the bucket.
  • The second pair rotates the bucket to dump its contents.
  • The third pair splits the bucket so you can use it to grab and pick up things (such as logs).

There are also hydraulic motors on the four wheels.
