Q:Card to bel 320d2gc hydraulic excavator how much money
The working device comprises a movable rod, a bucket rod and various changing equipment, such as a shovel, an anti shovel, a loading bucket, a grab bucket, etc., and the typical working cycle is as follows:(1) mining in hard Tucheng in general to the bucket rod bucket cylinder with action, adjust the cutting angle, with the excavation in soft soil slope mining; in turn, is dominated by bucket cylinder action; by the special requirements of the mining operation, the bucket cylinder and the bucket rod cylinder and boom cylinder three composite action. In order to ensure the specified trajectory bucket.(2) full bucket lifting and rotary excavation end, bucket cylinder launch, moving secondary cylinder rising, full bucket lifting; at the same time, slewing motor start, turntable turning to the direction of dumping.(3) unloading turntable to the unloading site, turntable brake bucket, cylinder adjustment, discharge radius, bucket cylinder recovery, bucket unloading. When there is a strict requirement on the unloading position and height, the arm Kr shall also be used.(4) after the end of the unloading, the turntable turns to the reverse direction, meanwhile, the movable arm cylinder cooperates with the bucket rod cylinder, so that the air bucket is lowered into the new digging bit.Single bucket hydraulic excavator is widely used in construction, transportation, water conservancy construction, open pit mining and modern military engineering. It is an indispensable main mechanical equipment in all kinds of earthwork construction.
Q:What are the specifications of excavators?
You didn't ask very clearly. A unit of length or weight, or what? The length is usually mm, and the unit of weight is usually kg. An imperial unit is usually inches in length and weighs t in weight

You can ask the number of cubic mining soil, professional concept: the excavator bucket capacity, but the bucket capacity refers to the full mark (according to the bucket is full, but around 45 degrees along the stack), note that the actual earthwork calculation, which can estimate the bucket capacity, but not a little poor.
Q:Komatsu excavator GPS positioning system, how to go inside to see?

For example, 1.2-1.1-1.0-0.8. various brands, various models of 200 machines, the speed of doing things are almost the same. Because of slow work, so big fight. Quick work makes little work. So both are small.
