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.



Main Product Features:

  1. There are 3 pumps: the two main pumps are for supplying oil at high pressure (up to 5000 psi) for the arms, swing motor, track motors, and accessories, and the third is a lower pressure (700 psi) pump for Pilot Control.

  2. The whole machine has the elegant streamline design, reliable performance and high efficiency of working.

  3. Possess quality certification of ISO 9001:2000. Can pass CE test.

(KOMATSU) advantages: better strength, strong and durable, low fuel consumption, hydraulic pressure is its strong point, the overall coordination is good, the speed is very fast, not easy to bad, good hedge, used car good shot. Disadvantages: high prices, accessories expensive. (Note: because of the domestic market share is very high, deputy plant parts, so it is cheaper): Japanese brands, Hitachi excavator sales is also very big, general can also assemble.

Q: I'm 18 and I live in Massachusetts, I recently committed a Vandalism crime that included my smashing a few windows on an abandoned (seemingly abandoned) excavator with a couple of friends. The damage came to (based on the police officers quick estimate) upwards of $250. I don't know why I or any of us did it but we feel horrible. The police came a few days ago at the scene of the crime and took our information. They also told us we would receive a summons to court in about 6 weeks. I and all of my friends are 18 and we all have perfectly clean records prior to this. We did a stupid thing and want to do anything and everything we can to rectify what we did. With a clean record and the cost of the damage done in mind...what's the worst that could happen to us? And is there any chance that this won't be put on our records if we take the proper steps...?
Since all of you are 18 this will go on your record. For sure restitution $250.00 Court fees, not sure what a Judge will give you. Could be Community hours. probation.
