The five advantages of Rotary Drilling Rig
1.A multi-purpose machine,achieving a variety of ways to drilling
In some countries, large pile holes and the design of rig foundation construction take advantage of the hydraulic Small Digger drive technology, by adopting the method of combination of modular design, under the same host, to achieve a multi-purpose machine to help the large-scale construction machinery adapting to different construction methods.
2.Advanced equipment performance, high automation level, low labor intensity
Rotary drilling rig is fully hydraulic Crawler Crane self-propelled drilling rig, using a full set of hydraulic system, some also equipped with advanced computer operating system. Rotary drilling rig has many features such as flexible operation, high mechanization, self-movable at the construction.
3.High-efficiency drilling
Rotary Drilling Rig can be configured with different drill bits according to strata.It is better to use long drilling tube in the clayey strata to speed up the drilling;it is better to use short drilling tube with slurry wall in the strata which contains plenty of sand and cobble to control the speed of drilling.Compared with conventional drilling rig, rotary drilling rig has long rotary torque, and can be automatically adjusted according to strata.Drilling pressure is big, and easy to control.At the same time the rotating drilling bit extracted rock and soil directly from the hole,so the speed of drilling is fast.Generally,the speed of drilling is 10m/h in the soil and sand,the speed of drilling is 4-6m/h in the clayey strata,which are 3 or 5times compared with the ordinary rotary drilling.
Sany provide different types of Rotary Drilling Rig as a world-class manufacture,his fifth generation of rotary drive adopts multi-gear control and self-adaption technology which can realize the perfectly match of crowd force and torque, the cutting efficiency can be increased by 15%.
