Exploring the Concept of Spiral Foraging A Unique Approach to Sustainable Harvesting
As a merit in the mining of rock, the drilling rig has to be mentioned. In addition, the drilling rig can also be used as a breaker to break up hard layers such as concrete. According to its power source, the rock drill can be divided into four categories: pneumatic rock drill, internal combustion rock drill, electric rock drill and digging and changing drill.
When the wind force is greater than level 6 during operation, the pile driver should stop the operation, and the oil cylinder should be used as an auxiliary support. If necessary, a wind rope should be added for fixing.When the crawler is piled, avoid the collision between the drill pipe reinforcement cage and other columns.
