What is the difference between a backhoe and a backhoe?
The form of shovel action of the shovel. It is characterized by "forward, upward and forced cutting."". The positive shovel has great excavation force and can dig the soil above the stopping surface. It should be used for the dry foundation pit with excavation height greater than 2m, but the upper and lower ramps should be set up.
According to the difference between the excavation route and the transportation vehicle, there are two ways to dig and unload the soil: forward excavation, lateral unloading, forward excavation and reverse dumpingAs compared with other forms of shoveling:(1): digging backhoe is characterized by "back down, forced soil cutting, the mining power shovel can stop a small, excavation to three below the soil surface, suitable for the foundation pit, foundation ditch, trench excavation depth is less than 4m, but also for soil excavation, wet soil with higher water content and to the underground water level and groundwater level in higher soil. There are two ways to operate the backhoe, namely, ditch end excavation and side ditch excavation.(2) pull shovel: digging features is "back down, self weight cut soil", and its excavation radius and excavation depth is larger, can dig the soil below the stop surface, it is suitable for digging large and deep foundation pit or underwater excavation.(3): grab digging is characterized by "straight up and down, cut the weight of soil, suitable for narrow and deep excavation pit mud or water, especially suitable for cutting under water, the soil is hard not grab construction.
Shovel bucket excavator with the same equivalent ratio of the bucket to be big, but not more than one to three excavation of soil water content of 27%, and with the completion of the whole mining dump truck transport operations, you can also tap the large drying pit and mound etc..
