How do excavator hydraulics work?
The pressure relies on the several-centuries-old scientific principle that liquids can’t be compressed. So pumps squeeze fluids in a hydraulic system through small diameter hoses and pipes — pressure in, pressure out — and mechanical force is created.
How does a hydraulic swivel work?
Swivel-type fittings are designed to allow the coupling and hose connection to rotate, which prevents twisting, kinking and excessive bending. Because swivel joints move, they can compensate for hose length changes when the system pressurizes and absorb hydraulic surges and shocks in a line.
How does a hydraulic rotary union work?
A rotary union functions by connecting a stationary input (supply) to a rotating part, allowing a moving connection to be preserved and permitting the flow of media (liquids, solids and gases).
How does an excavator rotate?
An excavator is made up of a boom, dipper (or stick) and bucket. These pieces connect to a cab that sits on a rotating house. Most houses can rotate a full 360 degrees. By swapping out the bucket for an auger, drill, ripper or rake the excavator can be used for many different jobs.
How many times can you swing an excavator to the left?

How deep of a hole can a mini excavator dig?
A 4,000- to 6,000-pound mini excavator can dig a 10-foot-deep hole. Larger 10,000- to 12,000-pound mini excavators allow dig depths as deep as 14 feet.
Can I dig a pond with a bulldozer?
To dig a pond with a bulldozer, you need to map the land, find the water source, and use the front blade to push out the dirt from the perimeter. Use a backhoe attachment to dig through the soil and create ledges along the way. Use liners, small rocks, and boulders to help with water retention.
Can you just dig a hole for a pond?
Depending on where the rock layer is found, the pond may need to be built completely or halfway above grade. The deeper you can dig, the better the pond will look. It’s tough to make a pond look natural when it’s sitting 18 inches above the surrounding soil. Once the pond is dug, you have two options.
