Product Description:

Excavators are heavy construction equipment consisting of a boom, stick, bucket and cab on a rotating platform known as the "house". The house sits atop an undercarriage with tracks or wheels. A cable-operated excavator uses winches and steel ropes to accomplish the movements. They are a natural progression from the steam shovels and often called power shovels. All movement and functions of a hydraulic excavator are accomplished through the use of hydraulic fluid, with hydraulic cylinders and hydraulic motors. Due to the linear actuation of hydraulic cylinders, their mode of operation is fundamentally different from cable-operated excavators.

Q:I recently lost my vision in one eye (permanently) due to lack of maintenance (on there end) on equipment that I rented. I rented a excavator from a rental company and shortly after using it part of the machinery (the tooth from the bucket) flew off and hit me in the eye permanently blinding me. Also there was no windshield on this to pull down for protection. Is there a legal case to this? The piece that hit me was approx. 3quot; wide x 6quot; long x 2quot; thick of solid steel, hitting me at approx. 30-40 mph and almost knocking me out. I'm not talking about a little piece of metal that would bounce off of safety glasses. The metal of course did not actually go into my eye but rather hit me so hard it smashed my eyeball flat. Also, we found out later that the bolts holding the tooth on were not the ones made for this excavator, were not the right size and were not hardened bolts. They should not have been used period.
Sounds to me like you might have a case unless somewhere in your rental aggrement there is a liability waiver realeasing the rental company of any liabilty in the event of injury but with the wrong bolts being inplace could be neglagence

I live in Hampton, VA and I wanna get a job for the summer in the Excavator/Dozer area, I have operated many tractors and such before, and know it can be very dangerous and know how to be safe, but is there anybody out there that will hire me?
If you're eligible at the age of 16 to drive a tractor, then by all means go ahead! In Malaysia, although 15 is the allowed age to drive a bus, it's illegal on the road. Please check with the NHTSA for more details.
