CM458 Crawler Mounted DTH Drilling Rig

Crawler Mounted Hydraulic DTH Drilling Rig

Automatic Crawler Mounted DTH Drill Rig, Crawler Mounted Drilling Rigs
Advanced Technology, easy to handle and operate.
Borehole Diameter
105～305mm
Site Condition
CM458 is applicable to all kinds of anchor supporting operation, grouting hole drilling for cofferdam, dam, and base reinforcement. Newly designed hydraulic clamp makes operation easier.
Product Features
CM458 internal combustion (CM458D Electric) crawler mounted versatile anchor rig adopts diesel engine and hydraulic oil pump assemblies to provide power, allowing rigs to finish moving, rotating, propelling and lifting, as well as angle positioning. During drilling，only the percussive hammer consumes compressed air. 
CM458 is applicable to all kinds of anchor supporting operation. In addition, the rig is also applicable to the grouting hole drilling for cofferdam, dam, and base reinforcement. Newly designed hydraulic clamp is a very useful device making operation easier.

What Are the Types of Drilling Rigs?

图片
With the continuous development of   drilling rig machine  production , the use conditions of drilling rigs are becoming more and more diverse, and various types of drilling rigs have appeared accordingly. Factors affecting the type and composition of drilling rigs include drilling methods, drilling depth, borehole size and drilling tool size, drilling area conditions (such as electricity or fuel, transportation, meteorological conditions), etc. The  t ruck mounted drill rig  is the main machine  that completes the drilling construction. It drives the drilling tool and the drill bit to the deep part of the formation and completes the lifting and lowering of the drilling tool and casing, and the extraction of the core through the elevator (winch) on the drilling machine. , Auxiliary work such as replacement of drill bit. The main function of the pump is to deliver flushing fluid into the hole to clean the bottom of the hole, cool the drill bit and lubricate the drilling tool. Dri

What Happens When Hydraulic Drilling Rigs Use Emulsified Hydraulic Fluid?

图片
  The emulsification of hydraulic fluid is the deterioration of hydraulic fluid. The use of emulsified hydraulic oil will have a very serious impact on the hydraulic system of hydraulic   drilling rigs , which is called the "white blood disease" of hydraulic drilling rigs.   Performance of hydraulic oil emulsification If you find that the hydraulic components of the hydraulic column drilling rig are weak, there are obvious bubbles in the oil tank and the oil temperature is too hot, it is recommended to open the oil tank cover to check whether the oil is white, if it is white and emulsified, it is recommended to clean the pipeline and replace the pure hydraulic oil immediately. Can no longer use emulsified hydraulic oil, "white blood disease" will really ruin the hydraulic drilling rig!   The danger of emulsified hydraulic oil to  hydraulic drilling rigs Hydraulic fluid emulsification is the deterioration of the hydraulic fluid. The use of emulsified hydraulic oil wi
