Product Description:

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.

  4. A wide range of operating weight & bucket size for your choice.

Q:why won't the excavator dig tunnel 6 in moon map in black ops?
Where the excavator breaches is largely based on luck, but it is more likely that it will breach tunnels you have opened already. I have also found that opening to the power room at round one will cause the excavator to breach at round one sometimes. Hope this helps!
