Skid/Loaders

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. If you watch the MPEG video you will be able to see these pistons and motors in action.
